Characteristics of Nuclear Power Plant Performance

PDF Version Also Available for Download.

Description

When analyzing U.S. commercial nuclear power plant performance in terms of selected initiating event frequencies and component unreliability, the data often appear to suggest two groups of performers - nominal and degraded. Given this observation, a limited review of the data was performed to investigate whether degraded performance typically is momentary or sustained. For example, do plants that exhibited degraded performance for a certain initiating event over one period also appear in the degraded performance category over the next period? The data review included a relatively simplistic review for two initiating events and two components followed by a more detailed ... continued below

Description

When analyzing U.S. commercial nuclear power plant performance in terms of selected initiating event frequencies and component unreliability, the data often appear to suggest two groups of performers - nominal and degraded. Given this observation, a limited review of the data was performed to investigate whether degraded performance typically is momentary or sustained. For example, do plants that exhibited degraded performance for a certain initiating event over one period also appear in the degraded performance category over the next period? The data review included a relatively simplistic review for two initiating events and two components followed by a more detailed analysis of one of the initiating events. The limited data review indicates that for the two relatively frequent initiating event categories and two important component types, the plant incursions into the degraded category are typically momentary (lasting one to several years) with subsequent returns to the nominal category. However, some interesting exceptions exist, and these need to be studied in more detail.
