PROCESS ERROR-INDUCED CRITICALITY ACCIDENT ANALYSIS FOR SAVANNAH RIVER SITE RECEIVING BASIN FOR OFFSITE FUEL

摘要

The Savannah River Site (SRS) Receiving Basin for Offsite Fuel (RBOF) is currently used to store fresh and spent nuclear fuel from a variety of domestic and foreign research reactors. As part of the accident analysis chapter of a DOE 5480.23 Safety Analysis Report (SAR) for RBOF, the combined frequency of occurrence for process error-induced criticalities was quantified using a combination of qualitative hazard analysis, quantitative fault tree analysis, and explicit criticality calculations. Using these analyses techniques, the frequency of process error-induced criticality at RBOF was estimated to be 8E-04 yr~(-1).
