Portsmouth continues to falsify records

Terrie Barrie, May 25, 2013

Jeff Walburn, former Portsmouth worker, must feel a little vindicated today. News broke yesterday that radiation monitoring devices used at Portsmouth were altered by employees and sub-contractors, http://www.dispatch.com/content/stories/local/2013/05/25/records-altered-at-closed-plant.html.

The reason for the falsification was “to avoid detection of problems with the hand-held radiation-detection monitors at the Portsmouth Gaseous Diffusion Plant, according to a May 22 memo from site project director Dennis J. Carr to company employees.” Fluor-B&W company spokesman, Jeff Wagner, explained the role of these devices, “Basically, they are one of the main sources of checking before people or materials leave an area.”

As noted in my July 26, 2012 blog, Mr. Walburn, along with two co-workers, has been trying to get someone in authority to notice this problem for years. They have been hammering away at officials that the Portsmouth records were falsified. In that blog post, Mr. Walburn stated, “I can’t understand why people here can’t get their minds wrapped around the fact that we had dosimeters but they were being altered purposely for bonus money.”

It appears there has been a long history of record falsification at Portsmouth. One of the reasons for Portsmouth’s inclusion in the SEC is because the dosimetry records were not accurate or reliable. On February 17, 1998, OSHA issued a Citation and Notification of Penalty to Lockheed Martin Utility Services, Inc. The type of violation is labeled as “Serious”. In part, OSHA found that:

“The employer did not preserve and maintain records of employee exposure of all (emphasis added) employees for at least thirty years:

a. Records of radiation exposures for all company employees were not adequately maintained from 1993 to 1995 (emphasis added)in that some employee exposures were arbitrarily assigned and based solely upon their past exposures which may have differed from exposures experienced during the period relating to the assigned dose.”

Who ordered the workers to alter the readings? Surely, they didn’t take it upon themselves to falsify the data. What would they have to gain – except maybe they followed orders in order to keep their jobs? I suppose we will have to wait until the DOE Inspector General issues their report on the investigation.

As you can imagine, this practice has serious implications for the workers. They have no idea if they received any radiation dose. I already wrote about NIOSH knowing about the record falsification in 2008, http://1.usa.gov/136qKPo, yet they haven’t changed their methods to reconstruct dose. How can NIOSH possibly defend their position knowing they are using falsified or incomplete records?

This latest incident is ample proof that NIOSH needs to abandon dose reconstruction for Portsmouth workers and recommend SEC status. Same should be done for the Rocky Flats site where not only is there a lack of complete documentation and where record falsification occurred but it was also raided by the FBI and ultimately shut down by DOE.

Radiation records altered, feds say
Piketon contractor says contamination did not enter public space.
By Lynn Hulsey

StaffWriter
PIKETON — Federal authorities are investigating allegations that a contractor’s employees altered documents to cover up problems with radiation detection equipment at a shuttered uranium enrichment plant in southern Ohio, according to federal and contractor officials.

Fluor-B&W/Portsmouth officials believe the documents were altered by “employees and sub-contract personnel” to avoid detection of problems with the hand-held radiation detection monitors at the Portsmouth Gaseous Diffusion plant, according to a May 22 memo from Site Project Director Dennis J. Carr to company employees.

The company is under contract with the Department of Energy to remove radioactive and toxic contamination at the 3,700-acre site where the federal government and its contractors enriched uranium for weapons and power plants between 1954 and 2001.

The monitors are used to measure alpha and beta radiation contamination on people and equipment.

“Basically, they are one of the main sources of checking before people or materials leave an area,” company spokesman Jeff Wagner said.

Officials have not identified any occurrence of an individual being contaminated or the improper release from a radiological area of contaminated equipment, materials or waste as a result of the problem, Wagner said.

“The investigation presented no evidence that anything associated with this issue left the radiation area or the site or entered any public space,” Wagner said.

25 altered entries

The issue was discovered in late April and both the company and the Department of Energy Inspector General opened investigations, Carr said.

“Intentional alteration of federal records is not only a breach of our company’s ethics policy and a Level 1 violation of our disciplinary policy, but could carry with it serious legal and/or contractual consequences for the involved individuals and the company,” Carr wrote.

Fluor-B&W found that about 25 “data entries documenting daily performance tests on handheld radiological monitors had been inappropriately altered,” said Tim Echelard, spokesman for the U.S. Department of Energy.

The monitors are tested daily, and in the process some showed readings about 15 percent outside the proper range, which should have resulted in them being pulled from service, said Wagner.

“It’s possible the equipment did not accurately read the level of radioactivity, but no materials monitored were ever able to leave the radiation area,” Wagner said.

Tim Echelard, DOE spokesman, said the company “confirmed that records had been retrieved and deliberately altered” and “appropriate employee actions” are being taken this week.

Wagner declined to say if those actions include firing radiation contamination personnel in charge of the meters. But Carr said the company will announce “new leadership” of the program.

Wagner said that within the radiation contamination organization “there was some supervisor/ management direction as well as supervision/ management knowledge about the issue but did not act on employee concerns.”

Carr urged employees to not comply with any order from a supervisor that is unsafe, unethical, illegal or violates regulations, and to report such violations to superiors.

Carr said the focus at Fluor-B&W is “recovering from the event and strengthening our Radiation Protection Program through the implementation of corrective actions,” including retraining of staff and verifying equipment is functioning properly.

While the U.S. Department of Energy Inspector General is investigating the allegations, the resulting report may not be made public, according to Felicia Jones, media liaison at the IG’s office.

Massive contamination

In 2006 the Dayton Daily News published a multipart investigation of radioactive and toxic contamination at the Pike-ton site, where secrecy cloaked activities by the government and its contractors, leading to massive contamination that made workers sick.

The Daily News investigation documented decades of slipshod safety practices, accidental toxic releases and routine mishandling of chemical and radioactive material. The cleanup work Fluor-B&W is doing is estimated to cost $2 billion. Taxpayers have paid the company $690 million since it began work in March 2011. The company is to decontaminate more than 400 buildings and systems, and complete environmental remediation of groundwater contamination and landfills on the site, Wagner said. Officials estimate the work will take until 2021 to complete.

Piketon was one of a trio of major government nuclear facilities in southern Ohio that were badly contaminated. The Mound Laboratory in Miamisburg and the Feed Materials Production Center in Fernald near Cincinnati also were cleaned at taxpayer expense.

The Piketon site — 100 miles southeast of Day-ton — also is home to USEC Inc.’s next-generation uranium centrifuges, which are still in the testing stage as the company seeks federal and investor funding for the project.

USEC operated the gaseous diffusion plant at Piketon before it closed. It also operates one in Paducah, Ky., which remains open.

Bob Hope
And The Road To Gi Joe
There was nowhere Bob Hope wouldn’t go to entertain the best audience he ever had—America’s WWII service men and women.
By Richard Sassaman

“There is a startling similarity between Bob Hope and Donald Duck,” wrote screenwriter and director Frank Tashlin. “Both became immensely popular during World War II. Both were braggers who backed down in a pinch but somehow prevailed.”

America’s greatest military entertainer during World War II (Bob Hope, that is), who couldn’t stop entertaining US troops for almost 50 years after the war, was not originally an American. Born Leslie Townes Hope in a London suburb in May 1903, Bob Hope came to Cleveland, Ohio, with his family when he was four years old. A few years after becoming a US citizen in 1920, he was a vaudeville performer appearing under the more masculine name Lester. But Lester becomes Les, and in 1929, perhaps feeling that Les Hope was not exactly inspiring, he changed his name again. “Bob—it seemed more down-to-earth—just like his audience,” wrote biographer Lawrence J. Quirk. “Bob Hope it would be.”

Hope’s five-decade career “covering the bases,” as his biographer William Faith describes it—some 60 tours from Korea to Vietnam to the Persian Gulf—began almost by accident. We weren’t even at war then. It was early May 1941 when his radio producer, Albert Capstaff, urged him to take The Pepsodent Show out of its Hollywood studio and do a live broadcast from March Field in nearby Riverside.

Hope didn’t see the point. Why not just bring the soldiers to the studio? Capstaff told him they numbered in the thousands. He didn’t mention his ulterior motive: his own brother was one of the soldiers. In the end, a group that included Hope’s mustachioed sidekick Jerry Colonna, announcer Bill Goodwin, and singer Frances Langford, who recently had replaced Judy Garland on the show, made the trip to March Field.

If nothing else, Hope figured, the show would provide welcome publicity for his upcoming summer movie, Caught in the Draft, but he was completely unprepared for what he found: “an audience so ready for laughter, it would make what we did for a living seem like stealing money.” He wrote later that “laughs came from simple harebrained foolishness, reluctant heroism, and even blatant cowardice set against a climate of high seriousness.”

“One of the aviators here took me for a plane ride this afternoon. I wasn’t frightened, but at two thousand feet one of my goose pimples bailed out.” (live at March Field, California)

The following week, the Pepsodent bunch was back in the studio after the trip to March Field, but when the impact of that first camp show became obvious, Hope and company began traveling around California in subsequent weeks to visit sailors at the San Diego Naval Station, marines at Camp Roberts north of Paso Robles, and soldiers at Camp Callan in La Jolla. By that time Caught in the Draft had become the most popular Paramount film of 1941. The pattern was set.

Only nine of Hope’s 144 radio shows during the war were broadcast from NBC’s studio. The others all took place at military bases. Hope would identify the base right away, opening his monologue with “This is Bob (insert location here) Hope.”

Sometimes the jokes were accidental. At one naval base, Langford set out to sing “You Go to My Head,” unaware that, to sailors, the “head” is the toilet. Almost always, the response was much greater than the material deserved. “The reason for our overwhelming welcome from troops all over the world,” Hope decided later, “was that we spelled, more than anything else, ‘home.’”

“In America, only the Boy Scouts were prepared.” (Don’t Shoot, It’s Only Me)

A poll published two days before Christmas 1941 in Radio Daily, the newspaper for commercial radio and television stations, confirmed the national appeal of the military broadcasts by naming Hope the top comedian and top entertainer of the year. Such honors didn’t mean much, however, coming in the somber weeks after the Japanese surprise attack on Pearl Harbor. Quirk wrote that Hope was irked on Sunday morning, December 7, because This Week magazine, a supplement to the Sunday edition of the Los Angeles Times, had reported his gross income for 1940 ($464,161.78). But the startling news coming over the radio from Hawaii quickly made him forget his irritation.

“I’ve been offering to kiss every movie star who bought a $500 [war] bond. But I only sold one, and Boris Karloff wants his money back.” (live at the Hollywood Canteen)

In the spring of 1942, Hope became master of ceremonies for the Hollywood Victory Caravan, a two-week tour of 12 American cities that was part of a film industry effort that ultimately raised a billion dollars for army and navy relief agencies. The caravan included 50 Hollywood stars, among them James Cagney, Bing Crosby, Olivia de Havilland, Cary Grant, Laurel and Hardy, Groucho Marx, Merle Oberon, and Spencer Tracy. They did skits written by big-name writers George S. Kaufman and Moss Hart and performed songs by popular composers Jerome Kern, Johnny Mercer, and Frank Loesser.

“You heard about the airman who was making his first parachute drop? Well, his first lieutenant told him which cord to pull, and told him that when he hit the ground there would be a station wagon waiting to drive him back to the base. So the airman jumped out of the plane and when he pulled the cord nothing happened, and he said, ‘And I bet the station wagon won’t be there either.’” (live in Alaska)

By the end of the two weeks, the Hope Gypsies, as Hope called them, were exhausted. But still they set off for 65 more shows at military bases and hospitals. By September the Gypsies, now including guitarist Tony Romano, had arranged their first USO (United Service Organizations) tour and set off to the US Territory of Alaska and the Aleutian Islands. The soldiers there, Hope later wrote, “were the loneliest guys in the world. Also the coldest.”

In the summer of 1943, the Gypsies, with Hope’s friend and ex-vaudevillian Jack Pepper filling in for Colonna, toured England and Northern Ireland. “The European theater,” Hope said, “was a little like vaudeville with foxholes.” Actor Burgess Meredith wrote to his future bride Paulette Goddard that “the most wonderful thing about England right now is Bob Hope…. He is tireless and funny, and full of responsibility, too, although he carries it lightly and gaily. There isn’t a hospital ward that he hasn’t dropped into and given a show; there isn’t a small unit anywhere that isn’t either talking about his jokes or anticipating them. What a gift laughter is!”

Hope made a cameo appearance in the one-hour 1943 training film Welcome to Britain, starring Meredith, which tried to explain the English people and their customs to newly arriving American GIs. (In the words of one reviewer, the documentary shows that “British coffee is awful, their beer is warm, they have a fetish about tea.”) Hope shows up in a scene with a taxi driver, discussing the English monetary system of pounds and shillings.

The Gypsies did their first USO combat zone shows that summer in North Africa, Italy, and Sicily. Palermo offered them both their largest audience—19,000—and a narrow escape with their lives when 100 Nazi Junker JU-88s with a fighter escort dive-bombed the docks, destroying the area around the troupe’s hotel a few blocks away. Hope said that returning safely to the States that fall “was something of a letdown. Hollywood was tinsel and make-believe and happy endings. Where we had been was mud and reality and horror.”

Along the road to the end of the war, Hope met his heroes Winston Churchill, Jimmy Doolittle, and Dwight Eisenhower, as well as other famous leaders such as General George Patton. Years later he admitted, “I miss the immediacy of feeling you’re a part of history, even though you’re not. Yes, I miss the wars, probably because I had the best of the excitement and the least of the danger.”

“What a beautiful swamp you have here…. It’s a top-secret base—even the snakes can’t find it. If you wanna hide from your draft board, this is the place to do it.” (live at Noemfoor, off New Guinea)

The following summer, 1944, the Gypsies were off again, logging more than 30,000 miles in the South Pacific, giving more than 150 performances on remote backwater islands, places like Eniwetok, Tarawa, Kwajalein, Saipan, and Majuro. Hope called it “Loew’s Malaria Circuit” or “the Pineapple Circuit.” At one show, the troupe found out that a Japanese soldier had been killed a few hundred yards from the stage.

It didn’t take Hope long to figure out how to win an audience of troops. “The essential element of foxhole humor, in Hope’s view, is that the GI laughed hardest when the joke was on him,” Faith wrote. In Hope’s words, “[The GI] can take it. He’s laughing off the icy cold, the searing heat, the bugs and the scorpions, his fears and his frustrations.” He also believed that the GI’s “real enemies, even after war broke out, were never just the Germans or the Japanese. The enemies were boredom, mud, officers, and abstinence. Any joke that touched those nerves was a sure thing.”

“There are some cynics who say I never met a war I didn’t like. They’re the ones who haven’t smelled it close up, in the hospital wards…. Politics didn’t matter to me. I never saw a 75mm shell wearing a Willkie button.” (Don’t Shoot, It’s Only Me)

In Caught in the Draft, Hope played a movie star who enlists in the army (along with his agent and chauffeur) because he wants to impress the base colonel’s daughter (played by Dorothy Lamour). In real life, of course, Hope, unlike stars such as Jimmy Stewart and Clark Gable, did not enlist. Some questioned his courage, carping that he kept appearing onstage in front of soldiers to stay out of the army. (When one GI in the back of a crowd in Tunisia, shortly after the August 1943 invasion of Sicily, yelled “Draft dodger!” at him, Hope quipped, “Don’t you know there’s a war on? A guy could get hurt.”)

Respected commentators such as combat reporter Ernie Pyle and novelist John Steinbeck disagreed with Hope’s critics. In a column for the New York World Telegram on September 16, 1943, Pyle wrote that he had traveled in two different cities with Hope’s Gypsies during air raids “and I will testify that they were horrifying raids. It isn’t often that a bomb falls so close that you can hear it whistle. But when you can hear a whole stack of them whistle at once, then it’s time to get weak all over and start sweating. The Hope troupe can now describe that ghastly sound.”

Steinbeck, who had won the Pulitzer Prize in 1939 for The Grapes of Wrath and would win the 1962 Nobel Prize in Literature, spent the second half of 1943 as a war correspondent for the New York Herald Tribune. He wrote a column published on July 26, 1943, that was probably the finest review Hope ever got for his wartime work.

“When the time for recognition of service to the nation in wartime comes to be considered,” Steinbeck began, “Bob Hope should be high on the list. This man drives himself and is driven. It is impossible to see how he can do so much, can cover so much ground, can work so hard, and can be so effective. He works month after month at a pace that would kill most people…. And he has been doing this ever since the war started. His energy is boundless.”

Near the end of his report Steinbeck wrote, “Probably the most difficult, the most tearing thing of all, is to be funny in a hospital…. Everything that can be done is done, but medicine cannot get at the lonesomeness and the weakness of men who have been strong. And nursing cannot shorten one single endless day in a hospital bed. And Bob Hope and company must come into this quiet, inward, lonesome place, and gently pull the minds outward and catch the interest, and finally bring laughter up out of the black water. There is a job. It hurts many of the men to laugh, hurts the knitting bones, strains at sutured incisions, and yet the laughter is a great medicine.”

The last sentence of Steinbeck’s dispatch read simply, “There’s a man for you—there is really a man.”

Time magazine added its approval four days after Pyle’s column, putting Hope—with the tagline “First in the Hearts of the Servicemen”—on the cover of its September 20, 1943, issue. The accompanying article, “Hope for Humanity,” noted that the comedian had just performed “about 250 camp and hospital shows in eleven weeks.”

The article began by citing Jack Benny, Ray Bolger, Al Jolson, Martha Raye, and others. “Never before have the folks who entertain the [troops] been so numerous or so notable; never have they worked so hard, traveled so far, risked so much…,” it read. “From the ranks of show business have sprung heroes and even martyrs, but so far only one legend. That legend is Bob Hope.”

Richard Sassaman lives in Bar Harbor, Maine. He has written for America in WWII about the atomic bomb, Bataan, Corregidor, the Doolittle Raid, and Nazi spies who in November 1944 visited what is now his neighborhood.

Inside K-25
Posted May 24th, 2013 by Alex Wellerstein

The K-25 plant at Oak Ridge was the single most expensive part of the Manhattan Project. It was cost about a fourth more than the entire Hanford site. Perhaps unsurprisingly, the building that housed it was pretty big — supposedly the largest single factory in the world under one roof, at the time that it was built.

I had thought about creating some kind of little graphic comparison to show you how big it was — you know, putting it next to The Pentagon and other large buildings — and then I realized that I wouldn’t really be flexing my geek cred, or taking advantage of a web medium, if I didn’t make a little custom mashup instead. So, I present for you a quick little app that I’m calling, How Big Was K-25?, where you can drag the footprint of K-25 onto anywhere in the world to make a size comparison:(If you only see a blank spot above, or if you want to view it larger than it is displayed in the blog post, then click here to open the page in its own window. Note that there is a “rotate” button in the upper-left corner, if you want to re-arrange K-25.)

And yet… despite its cost, despite its size, when one thinks of images of the Manhattan Project, even images of Oak Ridge, views of the inside K-25 aren’t what comes to mind. We’ve all seen the images of the Y-12 “racetrack,” and many of us have seen images of the face of the B-Reactor, but what does a gaseous diffusion plant look like?

A reader asked this question in a comment on last week’s post, and it got me scratching my head, and asking around on Twitter. I got enough interesting results that I felt it was worth a post in its own right, as opposed to just a long comment. I can think of two major reasons why this sort of thing isn’t as common in the photos of the bomb project, which I’ll include at the end.

These photos were mostly taken by Ed Westcott, the official Oak Ridge photographer during the war (and after), and are hosted by the Oak Ridge Public Library. (Special thanks to the American Museum of Science and Energy for pointing this resource out to me!)Both of these I like not only because of the color — how much of those paint jobs are post-1945, I don’t know — but also because the presence of people helps you get a sense of the scale of those vessels. They seem larger than the ones in the other photographs, so they may be later additions. Thanks to Jeffrey Lewis for pointing this out to me.

So why are these images dreadfully underrepresented in our collective imagination regarding the Manhattan Project? I offer three possible reasons.

One is the familiar problem of classification: gaseous diffusion was highly classified after the war. Unlike the electromagnetic enrichment method, or the basics of reactor operation, it wasn’t declassified in the early 1950s. There are still lots of things that are tied up tight as far as classification is concerned, despite the fact that gaseous diffusion is a pretty old technology, and arguably not the technology of choice for a modern proliferator (too expensive, too difficult).

Another is that gaseous diffusion arguably wasn’t as significant to the war effort as electromagnetic enrichment (though it wasn’t exactly insignificant, either); it came online a lot later, and really wasn’t perfected until after the war ended. Also, in comparison to the electromagnetic method, it also lacked as enthusiastic a booster as Ernest O. Lawrence, who was nothing if not entrepreneurial in promoting technologies that he was involved with.

And lastly, a potential other reason though is that as a concept it’s a bit harder to grasp, a bit hard to explain, and a bit harder to display visually, than other methods of enrichment. Electromagnetic enrichment is pretty easy to understand, and easy to diagram. And once you’ve seen how it works, suddenly images of Calutrons make a lot of sense — ah, there’s that C-shape. Rope them around a magnet and you’re done. It corresponds with nice intuitive notions of classical mechanics, and can be the source of all sorts of plain-language analogies (throwing heavier or lighter baseballs, for example).

Gaseous diffusion involves shooting gas through specialized barriers, relying on slightly different transit times, and visually, looks like just so many big tubs connected to one another. Internally it looks a lot like a lot of other anonymous industrial plants; its size, and its radioactivity, are perhaps the only things that make it obvious that it isn’t some kind of anonymous solvent factory. The kinds of diagrams explaining its operation that circulated in the early days were not exactly stimulating to thought, either.

All of this discussion of K-25, of course, is thoroughly in the past tense. Most of K-25 has been torn down; demolished. The DOE has been fairly unenthusiastic about preserving any of the K-25 buildings, despite their historical relevance. I think this is really, truly too bad. Whatever one’s feelings about the Manhattan Project, destroying historical sites doesn’t really help anybody. This is one of the reasons I’m a supported of the Atomic Heritage Foundation‘s efforts to have a number of the few remaining Manhattan Project sites declared part of a new Manhattan Project National Park. Aside from the possibility of using them as the focal point for interesting interpretations of our atomic history, it’s also necessary if we’re going to expect any remnants of these buildings to still be around in generations to come, as the Manhattan Project slides out of living memory. We can argue about the meaning of these sites for years and years — but only if we still have them to argue about.

The Berlin Wall, which existed from August 13, 1961 through November 9, 1989, was a powerful symbol of the Cold War. The border between West and East Berlin was literally shut down overnight when East German troops moved in during the night of August 12. Before day break, they had torn up streets entering West Berlin, put up concrete posts and strung barbed wire to prevent anyone from crossing what had been an open border.
