The safety record at the U.S. laboratory that created the atomic bomb is facing intensifying criticism as work ramps up to produce a key component for the nation’s nuclear weapons cache.
A series published this week by the Center for Public Integrity cites numerous internal reports and other documents outlining federal regulators’ concerns about safety lapses at Los Alamos National Laboratory over the years, including spilled plutonium and workers positioning plutonium rods in a way that could have been disastrous.
In an internal memo obtained by The Associated Press, Los Alamos officials took aim at critics and reassured employees of the safety of the lab’s facility for making plutonium cores known as “pits” used to trigger the explosions in nuclear bombs.
“As employees, you should be proud of your laboratory’s accomplishments over the past decade to strengthen our ability to operate safely and securely,” according to the memo, dated Monday. “While there will often be external organizations and individuals which advance a misleading narrative, it is not an accurate reflection of our work.”
It said the plutonium facility’s operations and safety programs have successfully undergone more than a dozen independent external reviews and that it’s close to being fully operational after safety problems forced work to be suspended in 2013.
Safety at the nation’s aging nuclear research labs is under scrutiny as federal officials grapple with issues that have been decades in the making. Aside from Los Alamos, U.S. Department of Energy officials recently said inadequate funding and the inability to clean up millions of gallons of toxic waste at the Hanford Nuclear Reservation in Washington state will likely lead to future accidental radiation releases.
The probe of Los Alamos by the nonprofit journalism organization caught the attention of top officials at the National Nuclear Security Administration, which oversees the lab, and members of New Mexico’s congressional delegation, who say safety should be the top priority given the lab’s role in maintaining and modernizing the U.S nuclear stockpile.
“There have been acknowledged mistakes that this report shines a light on that must be addressed,” U.S. Sen. Martin Heinrich, a New Mexico Democrat, said in an email to the AP.
Tom Udall, the state’s other Democratic senator, brought the issue up at a Senate appropriations subcommittee appearance Wednesday by DOE Secretary Rick Perry, who told Udall he believes LANL is “making significant progress.”
“The reviews are done, the ratings assessments were very deliberately and appropriately accomplished and [the pit program] has been brought back on line,” Perry said. He said DOE is on schedule to meet Department of Defense requirements for pit manufacturing. “The safety of the operations at our labs – I don’t think anything is more important,” Perry said.
The birthplace of the atomic bomb, Los Alamos has struggled for years to address management and oversight issues, along with more recent safety concerns about the handling of radioactive waste and plutonium.
Members of an independent federal oversight panel confirmed during a public hearing earlier this month that many of the alarm and fire suppression systems at the plutonium facility date to the 1970s, raising questions about the ability of the decades-old concrete building to accommodate the increase in plutonium pit production ordered by the Energy Department.
The Center for Public Integrity also pointed to a June 2016 incident in which technicians spilled several tablespoons of liquid containing plutonium, sopped it up with organic cheesecloth and threw away the cloth in waste bins with other nuclear materials. Federal rules prohibit using cheesecloth in such cleanups because contact with plutonium can trigger chemical reactions and fires.
