A government watchdog has accused officials at the giant Hanford nuclear weapons complex in Richland, Wash., of stifling dissent on safety matters by removing a project engineer the day after he complained about the safety of a radioactive waste treatment project.
In a strongly worded report, the Defense Nuclear Facilities Safety Board said the Department of Energy and its contractor Bechtel Corp., had promoted “a subculture…that deters the timely reporting, acknowledgement, and ultimate resolution of technical safety concerns.”
As a result, the report said, workers building a $12.2 billion radioactive waste treatment plant face an atmosphere of “unhealthy tension” that has made processes for resolving safety issues “largely ineffective.”
Workers at the Department of Energy’s 586-square-mile Hanford site are responsible for cleaning up billions of gallons of liquid radioactive waste and millions of tons of solid waste from nine former nuclear reactors and processing facilities that were built in the 1940s to produce plutonium, a radioactive element used to make atomic weapons.
The treatment plant, designed to stabilize radioactive waste by turning it into glass, is still under construction. It is required to start treating 53 million gallons of radioactive waste stored in underground tanks by 2019, according to The Tri-City Herald .
The safety board, created by Congress to provide oversight of the county’s nuclear weapons complex, launched the probe after former engineering manager Walter Tamosaitis was stripped of his duties when he complained about safety problems. The action “sent a strong message” to other “project employees that individuals who question current practices or provide alternative points of view are not considered team players and will be dealt with harshly,” the report said.
The investigation widened after allegations surfaced that the DOE also had tampered with witnesses at a public hearing conducted by the board.
The report was the culmination of interviews with 45 people and the review of 30,000 pages of documents. As one example of unheeded safety concerns, the report said that Bechtel suppressed a July 2009 study on the potential spread of radioactive particles offsite.
The nuclear safety board called on Energy Secretary Steven Chu to make major improvements. It also called for a review of Tamosaitis’ removal and treatment by DOE and Bechtel. According to the report, the former engineering manager now “sits in a basement cubicle with no meaningful work.”
