...though we didn't intend to eliminate the safety problems. Immediately after the TMI disaster, a task force of the Nuclear Regulatory Commission (NRC) developed a 600-page "TMI Action Plan," which outlined the major weaknesses in nuclear power plants in the U.S.--unreliable equipment, faculty backup cooling systems, insufficient operator training, poorly designed control rooms, inadequate data displays, etc. And to the NRC's credit, much progress has been made--in operator training, control rooms, pipe repairs...
...facilities are safer than Soviet ones in other ways. Unlike Soviet nuclear reactors, all NRC-licensed American installations are equipped with emergency core-cooling systems. These usually work by dumping tons of water into any reactor core that shows signs of overheating. Nor are U.S. reactors as likely to release radiation into the atmosphere in the event that the fuel starts melting. Only the newest of the Soviet Union's Western-style reactors are equipped with the steel-reinforced concrete containment buildings that are designed to hold in radioactive gases and the other by-products of an accident. All licensed...
...investigation, to be conducted by O'Connor, the Cambridge police and fire chiefs, was sparked by a report sent to the Nuclear Regulatory Commission (NRC) by Daniel Hirsch, an authority on research reactors at the University of California at Santa Cruz. The report stated that security for nuclear reactors must be improved substantially to protect such facilities from fuel-theft and sabotage...
...order effectively to protect the reactors, Hirsch said, "They need large exclusion zones and very serious security." He added that he could not be more specific because NRC regulations require that security measures remain secret...
Lincoln Clark, associate director of the MIT facility, said there is no need for an investigation or an increase in security. "We've been good neighbors in Cambridge for many years. We've increased levels of security as the NRC has published new regulations, and I don't think there is anything to worry about...
