Between 1950 and 2000, there were 21 serious incidents or accidents involving off-site radiological releases that warranted a rating on the International Nuclear Event Scale, one at level 5, five at level 4 and fifteen at level 3. Additionally, during the 1950s and 1960s there were protracted periods of known, deliberate discharges to the atmosphere of plutonium and irradiated uranium oxide particulates. These frequent incidents, together with the large 2005 THORP plant leak which was not detected for nine months, have led some to doubt the effectiveness of the managerial processes and safety culture on the site over the years.

On April 20, 2005, a camera inspection of a feed clarification cell at THORP revealed that 83,000 liters of dissolver solution had leaked from a broken pipe (Figure 1) into the cell sump. The highly radioactive dissolver solution, consisting of approximately 19 metric tons of uranium, plutonium and fission products dissolved in nitric acid, was entirely contained within the stainless steel-lined cell.
No personnel were injured as a result of this incident. However, the cleanup costs for this event are expected to exceed $500 million, and the THORP facility faces a lengthy shutdown (possibly even permanent closure).

Reprocessing also results in radioactive liquid waste: the French reprocessing plant in La Hague discharges 100 million liters of liquid waste (pdf) into the English Channel each year. "They have polluted the ocean all the way to the Arctic," Makhijani says. "Eleven western European countries have asked them to stop reprocessing."
