LANL chief denies lab hid facts from WIPP

=The head of Los Alamos National Laboratory issued a memo to employees Monday condemning a story published Sunday in The New Mexican that exposed missteps at the lab that had played a part in a WIPP radiation leak. The story also addressed efforts to downplay the dangers of LANL transuranic waste that had been sent to the nuclear waste storage facility near Carlsbad. The newspaper’s investigation, which took six months and included interviews and a review of thousands of documents obtained under the Freedom of Information Act, found that LANL documents provided to Waste Isolation Pilot Plant officials and regulators about the waste drum’s contents failed to mention several components: organic kitty litter, the unusually high acidity of the waste and a pH neutralizer. Now, those components are being eyed as possible factors in the chemical reaction that caused a LANL drum to burst, leading to the radiation leak. On Feb. 14, when the drum ruptured inside the underground storage facility, more than 20 workers were exposed to radiation. The plant has not reopened since, stranding thousands of barrels of waste from Cold War-era nuclear weapons production at national labs throughout the country. Fully reopening WIPP is expected to take up to five years and cost at least $550 million, according to the U.S. Department of Energy. “Over the weekend, many of you may have read a story in the Santa Fe New Mexican suggesting that Los Alamos National Laboratory was hiding scientific theories about the accident at the Waste Isolation Pilot Plant,” lab Director Charles McMillan wrote in his memo sent to LANL employees just before 5 p.m. Monday. “I want to assure you that nothing is further from the truth.” According to McMillan’s statement, obtained by The New Mexican, he took aim at a portion of the newspaper report about the lab’s delay in sharing a memo with WIPP personnel that likened the contents of the burst waste drum to explosives. The story reported that a May memo by LANL chemist Steve Clemmons asserted he had determined the waste in the drum that ruptured held the same components as three patented explosives. “The Lab was very open with the Department of Energy and the Carlsbad Field Office about hypotheses under evaluation, with daily discussions on all efforts to discover the cause of the breach and to ensure the safety and security of the remaining drums,” McMillan wrote in the memo to lab workers Monday. But emails that were the basis for the news report contradict McMillan’s memo. Those messages, colored at times by outrage from WIPP officials about what they weren’t told by LANL, show that despite daily briefings between WIPP and Los Alamos personnel about the ongoing investigations into the leak, a week passed before WIPP officials learned of Clemmons’ findings about the potentially explosive mixture in the waste...more
