U.S.NRC Progress in Source Term Evaluation

In this paper progress in the source term evaluation has been presented. This paper presents the development of Source term evaluation of Nuclear Power Plants (NPPs) for Probabilistic Risk Assessment (PRA) for operation and licensing of the NPPs. Substantial research had been carried out by NRC, for this purpose. Nuclear Research and development (R&D) Agencies like ANL, NEA, ORNL, SNL, BCL and ANS incorporate with U.S. NRC, and by the time they had published research reports on progress in risk assessments and source term evaluation of different accidental consequences in Commercial NPPs.
