This independent study demonstrates through state-of-the-art computer probabilistic, risk-assessment techniques that there would be one short-term fatality every 6,000 years at a nuclear plant and indistinguishable long-term cancer fatality risks from terrorist ground attacks involving a nuclear power plant. To put this in perspective, the short-term fatality estimate is over 80 times lower than NRC safety goals. The study was conducted by EPRI (Electric Power Research Institute).
