The NRC imposed tough sanctions on nuclear power plants that had low ratings.Īs a result, morale among personnel and managers at nuclear plants across the United States plummeted. It was a kind of nuclear reactor operators' capability assessment scheme that involved meticulously scoring each requirement. Japanese Prime Minister Naoto Kan's interference through Tokyo Electric Power Company ( TEPCO) executives caused great confusion in responses to the accident.Īfter the TMI accident, the NRC introduced a rigorous regulatory method known as SALP (Systematic Assessment of Licensee Performance). This was in stark contrast to the situation during the Fukushima Daiichi Nuclear Power Station accident following the Great East Japan Earthquake. Media reports on the steam venting caused panic locally, but radioactive contamination in the area was prevented. Although a core meltdown occurred, the accident was brought under control by venting steam from the containment vessel. This enabled Denton to respond promptly to the accident.

But soon thereafter a severe accident occurred at the Three Mile Island (TMI) Unit 2 nuclear power station in 1979.Īt the time, US President Jimmy Carter delegated full authority to Harold Denton, the director of the Office of Nuclear Reactor Regulation at the NRC. The US Nuclear Regulatory Commission ( N R C) was established in 1975 following organizational reform. This severely damaged the operating performance of nuclear power plants. Previously, the regulatory body wielded its authority to impose sanctions on nuclear power plant operators for even minor defects. The current NRA regulations are similar to the former nuclear regulatory approach of the United States. This was due to the insufficient improvement in two out of six requirements concerning counterterrorism measures.

Japan's Nuclear Regulation Authority ( NRA) on May 17 decided not to lift the de facto ban on the operation of Tokyo Electric Power Co's Kashiwazaki-Kariwa Nuclear Power Plant in Niigata Prefecture.
