RADIONUCLIDE RELEASE FROM SEVERE ACCIDENTS AT NUCLEAR POWER PLANTS EXECUTIVE SUMMARY Report prepared by a study group of the American Physical Society under contract with the U.S. Nuclear Regulatory Commission In 1983, the American Physical Society formed a study group on radionuclide release from severe accidents at nuclear power plants to "review the adequacy of the technical base upon which the phenomenological models for radionuclide release from postulated severe reactor accidents are constructed, the adequacy of the models themselves, and the correct use of the complex computer codes that incorporate these models in the analyses of accident sequences." The impetus to the existing research came from the observation that much less radioactive iodine was released during the Three Mile Island accident than had been expected in an accident of that Magnitude. It is of obvious interest to inquire how general that observation is. Although this executive summary describes, explains, and paraphrases some of the conclusions of this report, any reference should be to the specific conclusion as written in Chapter VIII rather than to the executive summary. This report is concerned with the release of radionuclides from a hypothetical severe nuclear reactor accident - - more severe than any that has yet taken place. It discusses both the predictions and the scientific basis for making them. Although we have not calculated probabilities of individual accident sequences, we have chosen for detailed discussion those sequences deemed by others to be "risk dominant" or to involve a wide range of physical and chemical phenomena.
