“Donna Busche, an employee of San Francisco-based URS Corp., said executives at the company told her she was being fired for “unprofessional conduct” before she was escorted out of the company’s offices at the site in central Washington.

The company denied that her dismissal was punitive or connected to her criticism of the project.

Busche is at least the third senior project official at Hanford who has been fired or who left under duress after raising concerns about safety at the massive $13.4-billion construction project, which has been stalled for more than a year over concerns about its basic design.”

Wikipedia entry for Hanford:

he Hanford Site is a mostly decommissioned nuclear production complex operated by the United States federal government on the Columbia River in the U.S. state of Washington. The site has been known by many names, including: Hanford Project, Hanford Works, Hanford Engineer Works or HEW and Hanford Nuclear Reservation or HNR. Established in 1943 as part of the Manhattan Project in the town of Hanford in south-central Washington, the site was home to the B Reactor, the first full-scale plutonium production reactor in the world.^[1] Plutonium manufactured at the site was used in the first nuclear bomb, tested at the Trinity site, and in Fat Man, the bomb detonated over Nagasaki, Japan.

During the Cold War, the project was expanded to include nine nuclear reactors and five large plutonium processing complexes, which produced plutonium for most of the more than 60,000 weapons in the U.S. nuclear arsenal.^[2][3] Nuclear technology developed rapidly during this period, and Hanford scientists produced many notable technological achievements. Many of the early safety procedures and waste disposal practices were inadequate, and government documents have since confirmed that Hanford’s operations released significant amounts of radioactive materials into the air and the Columbia River, which still threatens the health of residents and ecosystems.^[4]

The weapons production reactors were decommissioned at the end of the Cold War, but the decades of manufacturing left behind 53 million US gallons (200,000 m³) of high-level radioactive waste,^[5] an additional 25 million cubic feet (710,000 m³) of solid radioactive waste, 200 square miles (520 km²) of contaminated groundwater beneath the site^[6] and occasional discoveries of undocumented contaminations that slow the pace and raise the cost of cleanup.^[7]

The Hanford site represents two-thirds of the nation’s high-level radioactive waste by volume.^[8] Hanford is currently the most contaminated nuclear site in the United States^[9][10] and is the focus of the nation’s largest environmental cleanup.^[2]
