Sandjjn (OP) User ID: 28872052 United States 05/31/2013 07:55 PM Report Abusive Post Report Copyright Violation | Update: Slow Cooker at Paducah Comes to a Boil [link to ecowatch.com] Of greatest safety concern in a dirty power-down is the “slow-cooker” phenomenon, so-called by engineers, though the term itself is considered classified, and workers at the gaseous diffusion sites in Tennessee, Ohio and Kentucky have been ordered not to utter it. As a nuclear engineer for the Navy in the early 1950s, Jimmy Carter was assigned to work on gaseous diffusion design and may have contributed to invention of the term. ... A “slow cooker” is a critical mass of uranium and transuranic elements that forms inside the process equipment of a gaseous diffusion plant due to injudicious operation or a loss of power that causes process gas to crystallize. An undisclosed number of slow-cookers has occurred at the gaseous diffusion plants, mostly at the X-326 high-assay building at Piketon, Ohio, where the Criticality Accident Alarm Safety System (CASS) activated on May 22, causing building evacuation during cleanup, according to reliable informants. Ironically, that was the same day that my post about Paducah closure appeared. The phenomenon was first theorized by the physicist Edward Teller, father of the American H-Bomb, when he visited Oak Ridge during the Manhattan Project. Though the piping in diffusion plants has been designed to prevent any normal critical mass of uranium, as in an atomic bomb, from forming, Teller worried that the combined neutron flux from bringing many hundreds of tons of uranium into relative proximity could yield unanticipated criticality effects. That possibility has been magnified at Paducah because, in the 1960s and 1970s, recycled uranium containing significant amounts of plutonium, americium and neptunium, was fed into the Paducah diffusion cascade, resulting in worker and environmental exposures that made headlines in the 1980s. Plutonium and other transuranic elements intensify the possibility of critical mass formation, in ways that cannot be entirely predicted because no gaseous diffusion plant contaminated with transuranics has ever been powered down dirty before. Yes, this is a big science experiment. But hey, kids, don’t try this at home! |

Sandjjn (OP) User ID: 28872052 United States 05/31/2013 08:38 PM Report Abusive Post Report Copyright Violation | Here's basically the explanation regarding the possible effects: Lyn says: May 28, 2013 at 6:11 pm So that alleviates some of the concern regarding explosions. What about the likelihood of a release of dangerous gases like uranium hexafluoride, u-235, u-238, aluminum, or anything else used in the cascade. Is this something local residents should be concerned about? Geoffrey Sea says: May 29, 2013 at 1:05 pm Lyn, absolutely, because the seals which are leaking already will only degrade over time. This only one of the Paducah Catch-22s. It is not safe to demolish the facility if the cascade was not thoroughly purged prior to power-down. However, there is no funding for a complete purge. And it is not safe to allow the plant to degrade in an idle state. I might suggest federal legislation to mandate a residence-exchange program, so that Paducah local fence-line residents obtain title to USEC CEO Welch’s posh mansion in northern Virginia, and Welch is required by law to reside on the fence-line of the Paducah plant. I’m told that Mr. Welch has a private court behind his home, which might serve as partial compensation to Paducah residents suffering from chronic toxic exposures. |

Anonymous Coward User ID: 20478377 United States 05/31/2013 09:28 PM Report Abusive Post Report Copyright Violation | The OP has no idea what he is talking about. It will take 60 years to clean up. That is expected. There are already new plants in operation to take up the slack. It was too costly to keep running. The only problem with letting all the techs and engineers go is that it raises the cost of decom'ing. |
Anonymous Coward User ID: 29667147 United States 05/31/2013 09:31 PM Report Abusive Post Report Copyright Violation | This is fear mongering. They are not going to just drop their tools and walk away. Read the press release from USEC: [link to www.usec.com] USEC will take steps to cease enrichment at the Paducah plant over the next month and to prepare the plant site for return to DOE. USEC expects to continue operations at the site into 2014 in order to manage inventory, continue to meet customer orders and to meet the turnover requirements of its lease with DOE. We will be working with DOE during the coming months and expect to reach agreement on how to best transition the site. The company and our workforce have unparalleled expertise that should be drawn on. We can provide significant value to the government in making that transition in the most cost-effective and timely manner,” Van Namen said. USEC expects to begin reducing its workforce at the plant in the coming months. The Company will begin notifying workers as the specifics of the transition activities are defined. USEC anticipates maintaining a workforce at the site into next year to support ongoing operations, perform transition activities and meet regulatory requirements. |

It is a gaseous diffusion operation....meaning, that they are producing nuclear fuel, and there is no chance of any explosion... Remember, the bombs are never where the fuel for them is created...and that's what you're seeing here... |
endtimes101 User ID: 8915967 United States 05/31/2013 09:38 PM Report Abusive Post Report Copyright Violation | Disaster is about to strike in western Kentucky, a full-blown nuclear catastrophe involving hundreds of tons of enriched uranium tainted with plutonium, technetium, arsenic, beryllium and a toxic chemical brew. But this nuke calamity will be no fluke. It’s been foreseen, planned, even programmed, the result of an atomic extortion game played out between the U.S. Department of Energy (DOE) and the most failed American experiment in privatization, the company that has run the Paducah plant into the poisoned ground, USEC Inc. Quoting: Sandjjn As now scheduled, main power to the gargantuan gaseous diffusion uranium plant at Paducah, Kentucky, will be cut at midnight on May 31, just nine days from now—cut because USEC has terminated its power contract with TVA as of that time [“USEC Ceases Buying Power,” Paducah Sun, April 19, page 1] and because DOE can’t pick up the bill. DOE is five months away from the start of 2014 spending authority, needed to fund clean power-down at Paducah. Meanwhile, USEC’s total market capitalization has declined to about $45 million, not enough to meet minimum listing requirements for the New York Stock Exchange, pay off the company’s staggering debts or retain its operating licenses under financial capacity requirements of the Nuclear Regulatory Commission. The Paducah plant cannot legally stay open, and it can’t safely be shut down—a lovely metaphor for the end of the Atomic Age and a perfect nightmare for the people of Kentucky. [link to ecowatch.com] TOTAL BS - they will safely shut down. Thread fail. |
