Preliminary Nuclear Criticality Safety Evaluation for the Container Surveillance and Storage Capability (CSSC) Project

摘要

Washington Safety Management Solutions (WSMS) provides criticality safety services to Washington Savannah River Company (WSRC) at the Savannah River Site. One activity at SRS is the Container Surveillance and Storage Capability (CSSC) Project, which will perform surveillances on 3013 containers (hereafter referred to as 3013s) to verify that they meet the Department of Energy (DOE) Standard (STD) 3013(1) for plutonium storage. The project will handle quantities of material that are greater than ANS/ANSI-8.1(2) single parameter mass limits, and thus required a Nuclear Criticality Safety Evaluation (NCSE). The WSMS methodology for conducting an NCSE is outlined in the WSMS methods manual(3). The WSMS methods manual currently follows the requirements of DOE-O-420.1B(4), DOE-STD-3007-2007(5), and the Washington Savannah River Company (WSRC) SCD-3(6) manual. DOESTD-3007-2007 describes how a NCSE should be performed, while DOE-O-420.1B outlines the requirements for a Criticality Safety Program (CSP). The WSRC SCD-3 manual implements DOE requirements and ANS standards. NCSEs do not address the Nuclear Criticality Safety (NCS) of non-reactor nuclear facilities that may be affected by overt or covert activities of sabotage, espionage, terrorism or other security malevolence. Events which are beyond the Design Basis Accidents (DBAs) are outside the scope of a double contingency analysis.
