User's Guide for PRISIM (Plant Risk Status Information Management System) Arkansas Nuclear One - Unit 1. Volume 1. Program for Inspectors,

摘要

The user's guide is a two-volume document designed to teach NRC inspectors and NRC regulators how to access probabilistic risk assessment information from the two Plant Risk Status Information Management System (PRISIM) programs developed for Arkansas Nuclear One - Unit One (ANO-1). Volume 1 describes how the PRA information available in Version 1.0 of PRISIM is useful for planning inspections. Using PRISIM, inspectors can quickly access PRA information and use that information to update risk analysis results, reflecting a plant's status at any particular time. Volume 2 describes how the PRA information available in Version 2.0 of PRISIM is useful as an evaluation tool for regulatory activities. Using PRISIM, regulators can both access PRA information and modify the information to assess the impact these changes may have on plant safety. Both volumes are stand-alone documents; each volume presents several sample computer sessions designed to lead the use; through a variety of PRISIM applications used to obtain PRA-related information for monitoring and controlling plant risk.
