In-Plant Reliability Data Base for Nuclear Plant Components: Interim Report - Diesel Generators, Batteries, Chargers, and Inverters.

摘要

The objective of the In-Plant Reliability Data (IPRD) program is to develop a comprehensive, component-specific reliability data base for probabilistic risk assessment and for other statistical analyses relevant to component reliability evaluations. This objective is being attained through a cooperative effort with several utilities which have provided access to maintenance files and pertinent population information. This pilot data base includes (1) a component population list (for each plant) of selected electromechanical and mechanical equipment (e.g., pumps, valves, etc.), and (2) comprehensive component failure and repair histories based on corrective maintenance actions on these components. This document is the product of a pilot study that was undertaken to demonstrate the methodology and feasibility of applying IPRDS techniques to develop and analyze the reliability characteristics of key electrical components in five nuclear power plants. These electrical components include diesel generators, batteries, battery chargers and inverters.
