Value-Impact Assessment for a Candidate Operating Procedure Upgrade Program.

摘要

The report documents a value-impact assessment that was undertaken to assist the U.S. Nuclear Regulatory Commission (NRC) in determining whether it should implement regulatory action that would specify requirements for the preparation of acceptable normal and abnormal operating procedures by the NRC's licensee nuclear power plants. The following steps were used in the assessment: (1) the proposed NRC regulatory action was defined as the NRC requiring each U.S. nuclear plant to undertake a program to upgrade its normal and abnormal operating procedures, (2) the attributes effected by this action were identified, and (3) sensitivity analyses were performed to show how changes in important data would affect the expected changes in the attributes. The individual evaluations were then summarized and the value-impact results displayed.
