- Abstract
- The objective of this review is to evaluate the South Texas Project (STP) Probabilistic Safety Analysis (PSA) for the USNRC. The PSA was reviewed for thoroughness of analysis, accuracy in plant modeling, legitimacy of assumptions, and overall quality of the work. The review is limited to the internal event analysis and the fire accident analysis. This review is not a pass/fail evaluation of the adequacy of the PSA. The adequacy of the analysis depends on the intended uses and must be addressed on a case-by-case basis by the licensee and the NRC. This review identifies strengths, weakness, and areas where additional clarification would assist the NRC in evaluating the PSA for specific regulatory pruposes. The licnesee, Houston Lighting and Power (HLP), reviewed this report prior to its final release to the NRC. The responses provided by HLP are provided in detail in appendices to this report, and they are summarized in the main body of the report. All issues raised in the review were adequately addresseed by HLP in their responses.
