This year, 1992, marks the 50th anniversary of the first sustained nuclear reaction in the pile at the University of Chicago's Stagg Field. But it also marks the 30th anniversary of the publication of TID-14844, which has served as the design-basis source term for radiological assessments supporting the licensing of nuclear power plants in the United States since its inception. The conservative TID-14844 model assumes that 100% of the noble gases and 50% of the iodines are instantaneously released to the containment and are available for leakage to the environment. TID-14844 is formally embodied in the US Nuclear Regulatory Commission's (NRC's) regulations in parts 10CFR100 (siting) and 10CFR50 (review of control room habitability, postaccident shielding and sampling systems). It is also embodied in a host of NRC Regulatory Guides and NUREG reports that address off-site consequences of releases of radioactivity, equipment qualification, and other postaccident radiological concerns. On April 20, 1992, the NRC staff presented to the NRC commissioners the draft Revised Accident Source Terms for Light-Water Nuclear Power Plants.' This effort is documented in SECY-92-127 and provides the first official position of the NRC in this matter.
