NRC-19-81-494 Page 2 of 5 ARTICLE I - STATEMENT OF WORK A.,Backgroun'd The Three Mile Island (TMI) accident experience, when added to previous data, has raised important questions about the continued validity of accident release source. term assumptions that underlie many U. S. Nuclear Regulatory Commission (NRC) reactor regulatory policies and practices.
For example,.in order to bound the radiological consequences of Design Basis Accidents, the NRC Regulatory Guides 1.3 and 1.4 define the assumptions to be made in determining whether a plant meets the 10 CFR 100 radiological guidelines. TheseRegulatorfGuidesincluderequire-ments to ' assume a release from containment of 100 percent of the core inventory of noble gases and 25 percent of the iodine. Because of its relative abundance, its high radiotoxicity, and its assumed release and transport in vapor form, radiciodine is nearly always the most signifi-cant fission product, from a health hazard viewpoint, in Design Basis Accident evaluations.
In a letter to Chairman Ahearne dated August 14, 1980, three scientists from National Laboratories expressed their belief that, based on data that included the experience of the TMI accident, current NRC models and Regulatory Guides may not correctly describe the release of iodine during reactor accidents.
If the present state of knowledge or further research should demonstrate the validity of their assertions, it could have a major impact on present Commission policies and practices.
Fol-lowing a November 18, 1980 briefing by proponents of the idea of the need for such change, the Commission directed the staff to undertake, on an expedited basis, a thorough study of the state of technological knowledge of fission product source terms and a companion study of the implications of the source term study for regulatory policies and practices.
The Commission has requested that the NRC Office of Policy Evaluation (OPE) provide, with Contractor assistance, a short-tenn independen' evaluation of NUREG-0772 now being prepared by the NRC staff.
B.
Objective Task A -- Provide an evaluation of the technical adequacy of NRC staff report o'n the current state of technology and knowledge concerning radioiodine and other fission product species which could be released in a reactor accident.
C.
Work to be Performed Task A -- Evaluate NUREG-0772, " Technical Bases for Estimating Fission Product Behavior During LWR Accidents"
