A new perspective on the consequences of a potential reactor accident are discussed. TMI accident showed that the release of hazardous radionuclide iodine-131 was radically different than specified in the NRC regulatory model. The reactor safety study (WASH-1400) also had many conservative assumptions (called ''conservatisms'' in this paper). These conservatisms are identified and their effects tabulated. The conservatisms for predictions of the source term are numerous. R and D in the source term is needed in these topics: aerosol transport in primary coolant systems, water scrubbing in fission products, aerosol transport in containment, and the duration of containment integrity. The implications of a smaller source term on the degree of safety system requirements and severe accident rulemaking are briefly discussed.
