Rank ordering of vital areas within nuclear power plants
The conceptual development of a methodology for rank ordering vital areas within nuclear power plants based upon times associated with sabotage events and their consequences is discussed. The important time parameters in the analysis include the time required to detect the perpetration of sabotage, the time required to repair or mitigate the consequences of the sabotage and the total time available to perform these functions before it is too late to reverse the damage. These time interval parameters are incorporated into an interruption analysis importance measure that provides information on the ability of the protection systems to cope with the results of the sabotage. A consequence analysis that considers categories of release characteristics is the next step in the ranking scheme. Results of the interruption and consequence analyses are combined to attain a risk index associated with each vital area. The final ranking can be used to order upgrade priorities and to allocate scarce protection resources effectively.
