Probability of Failure of the Waste Hoist Brake System at the Waste IsolationPilot Plant (WIPP)

摘要

The Department of Energy (DOE) has continues to improve the design and operationof the waste hoist brake system at the Waste Isolation Pilot Plant (WIPP) culminating in a design fully describes in a recent report: a Revised Design, WCAP-13800 (Westinghouse 1994). Component failure data for the report were taken from NPRD-91 (Denson et al. 1991). However shortly after publication of the Revised Design an updating of component failure data became available in the newly published NPRD-95 (Denson et. al 1994).
