Trump administration neuters nuclear safety board

The Trump administration has quietly taken steps that may inhibit independent oversight of its most high-risk nuclear facilities, including some buildings at Los Alamos National Laboratory, a Department of Energy document shows. An order published on the department’s website in mid-May outlines new limits on the Defense Nuclear Facilities Safety Board — including preventing the board from accessing sensitive information, imposing additional legal hurdles on board staff, and mandating that Energy Department officials speak “with one voice” when communicating with the board. The board has, by statute, operated independently and has been provided largely unfettered access to the nation’s nuclear weapons complexes in order to assess accidents or safety concerns that could pose a grave risk to workers and the public. The main exception has been access to the nuclear weapons themselves. For many years, the board asked the Department of Energy to provide annual reviews of how well facilities handled nuclear materials vulnerable to a runaway chain reaction — and required federal officials to brief the board on the findings.

GOP chair of nuclear safety agency secretly urges Trump to abolish it

The chairman of a panel charged with protecting workers at nuclear weapons facilities as well as nearby communities has told the White House he favors downsizing or abolishing the group, despite recent radiation and workplace safety problems that injured or endangered people at the sites it helps oversee. Republican appointee Sean Sullivan, a former Navy submarine officer, told the director of the Office of Management and Budget in a private letter that closing or shrinking the Defense Nuclear Facilities Safety Board he chairs is consistent with President Trump’s ambition to cut the size of the federal workforce, according to a copy of Sullivan’s letter. It was written in June and obtained recently by the Center for Public Integrity. The five-member Defense Nuclear Facilities Safety Board, chartered by Congress, has helped persuade the federal government to impose tighter safety rules and regulations at most of the eight nuclear weapons sites — employing more than 40,000 workers — where nuclear weapons and their parts are produced or stored. Nonetheless, the nuclear weapons complex in recent years has experienced alarming problems, including the mishandling of plutonium, a radioactive explosive; the mis-shipment of hazardous materials, including nuclear explosive materials;  and the contamination of work areas and scientists by radioactive particles — shortcomings detailed in a recent Center for Public Integrity investigation. Sullivan’s position is consistent with the longstanding preferences of the large private contractors that produce and maintain the country’s nuclear arms, most of which also contribute heavily to congressional election campaigns and spend sizable sums lobbying Washington.

Light penalties and lax oversight encourage weak safety culture at nuclear weapons labs

The plan on a hot summer day was to liquefy highly flammable lithium at a temperature of more than 750 degrees and then pump it into a special chamber for cooling, as part of a research project at Sandia National Laboratories in New Mexico.  But what happened instead in August 2011 was a near-catastrophe that could easily have killed two workers. The experiment was designed to help learn more about lithium’s potential use in an advanced nuclear reactor. But it went awry when someone turned the wrong valve and the heater holding the lithium cracked, causing the molten liquid to leak and spray abruptly onto a pipe holding the coolant. The result was a steam explosion, a hydrogen explosion — or likely both — in the lab’s Plasma Materials Test Facility.

Safety problems at a Los Alamos laboratory delay U.S. nuclear warhead testing and production

In mid-2013, four federal nuclear safety experts brought an alarming message to the top official in charge of America’s warhead production: Los Alamos National Laboratory, the nation’s sole site for making and testing a key nuclear bomb part, wasn’t taking needed safety precautions. The lab, they said, was ill-prepared to prevent an accident that could kill lab workers, and potentially others nearby. Some safety infractions had already occurred at the lab that year. But Neile Miller, who was then the acting head of the National Nuclear Security Administration in Washington, says those experts specifically told her that Los Alamos didn’t have enough personnel who knew how to handle plutonium so it didn’t accidentally go “critical” and start an uncontrolled chain reaction. Such chain reactions generate intense bursts of deadly radiation, and over the last half-century have claimed nearly two dozen lives.

Audit: Nuclear lab lets safety gaps languish for years

An obscure facility at Los Alamos National Laboratory for nine years provided vital scientific data about a critical gas used in America’s arsenal of nuclear weapons, until it was shuttered four years ago due to a raft of safety problems that have stubbornly persisted. The Energy Department, which oversees and finances the lab’s work, has poured tens of millions of dollars into fixing the problems, but so far, the expenditures haven’t borne much fruit. The facility – known as the Weapons Engineering Tritium Facility – is “vital” to the lab’s national security mission, but it remains closed, the department’s inspector general said in a report released July 20. In fact, Los Alamos managers have been unable – after seven years of effort – even to prepare a sound analysis of the site’s safety hazards and the steps being taken to ensure that the radioactive gas at issue does not leak or explode and harm either workers or those living nearby, according to the DOE report. DOE Inspector General Gregory H. Friedman said in the report that poor hazard analysis has been a recurrent problem at the lab, and said weaknesses in other projects have remained unfixed from one annual evaluation to the next.
