INTERNAL committed to Nude.r r;1xC..o-.., CORRESPONDENCE NPM 2002-0293 To: Randy Amundson From: James Masterlark 1 Date: June 4 th, 2002
Subject:
Risk Ranking of Human Actions from the PBNP PRA Copy To: Paul Knoespel Rick Wood Paul Smith Terry Vandenbosch The purpose of this memo is to transmit a risk ranking of human actions from the latest PRA update (Version 3.03). I am including 2 tables that rank the Human Actions from two perspectives: Fussell-Vesely (F-V) importance and risk achievement worth (RAW). Which of these rankings to use depends on the application.
F-V importance of a human action is the fraction or percent contribution to the total core damage frequency (CDF) attributable to the human action being performed incorrectly. It can also be looked upon as a measure of the maximum reduction in total CDF achievable based on the complete reduction in error probability of a human action, (i.e., error probability approaches 0). Therefore, F-V importance is a good measure to use when
.iding which operator actions should have high quality procedures and enhanced (not necessarily more)
.Lining. The underlying assumption is that effective training and simplified procedures can reduce the error rate of the human action. Increasing the reliability of a human action with a low F-V importance will not result in a significant reduction in core damage risk. Therefore, it is not generally in the best interest of the plant to develop and implement enhanced training or procedures for a human action with a low F-V importance. Table I lists the top 15 human actions in order of highest to lowest F-V importance.
RAW is a measure of the increase in total CDF assuming the human action is never performed correctly (i.e.,
error probability is 1). This measure is not truly risk informed as it only relates to the consequences of the error without regard for the likelihood of occurrence (in reality it is a hybrid deterministic/probabilistic measure combining an assumed error, and the probabilistic result of the error). For example, a simple action to start a turbine driven pump from the Control Room will have a higher RAW than the pump due tor the lower failure probability of the human action even though the consequence of the failures is the same (i.e., the pump doesn't work). This would lead one to believe that the action to start the pump is more important than the pump itself, and more resources should be spent training on the human action when in reality, the weak link is the pump.
Human actions with a high error probability but a low RAW will have little or no impact on CDF if the error robability is reduced. Also, a human action with a high RAW but an error probability that is already low (less han about IE-3) cannot, in most cases, be improved no matter how much the training or procedures are nhanced. However, a high RAW does indicate human actions for which training should not be reduced or rocedures made more complicated. Table 2 lists the top 15 human actions in order of highest to lowest RAW:
REC'D JUN II Z002
To obtain the most useful information from these two ranked lists, both should be examined in combination for specific type of insights they provide. Please contact me or anyone in the PRA Group if you have any Muesttons on how to apply this information. We will be happy to meet with you to discuss it.
