12. February 19th, 2005 Non-CO 2 -emitting Energy Sources for the Future Safety of Current Nuclear Plants n There has not been a loss of life in the US due to commercial nuclear plants (TMI released a small amount of radiation) n Chernobyl accident - a terrible accident with a bad design u These plants are now closed or redesigned for operation u Russian nuclear plant operations are being assisted by IAEA n Regional deregulation of the electricity industry introduces challenges to continue & enhance the safety of nuclear plants. D - Upgrades of power plant equipment and reliable replacement schedule D - Risk-informed decision making by the industry should be cost-effective US nuclear plants are now self-insured via Price-Anderson Act and we should renew Price-Anderson legislation for long-term
