Resolution of Generic Safety Issues: Item B-3: Event Categorization ( NUREG-0933, Main Report with Supplements 1–34 )
There are several inconsistencies in event categorization between the GDC, SRP, Standard Format, and applicant submissions. In addition, categorization by other groups such as ANSI and ANS is not always consistent with NRC positions. In several cases, applicants have proposed that certain events be categorized as accidents (which would permit limited fuel damage) whereas the staff categorizes them as anticipated transients. This NUREG-04713 task will categorize the postulated transients and accidents and define acceptance criteria for the various categories. The result will be an improved licensing process and possible relief from current restrictive requirements for some licensees.
The categorization and definition of acceptance criteria are part of the staff routine activities such as revising the SRP.11 Thus, this Licensing Issue should be dropped from further consideration.412
