e of the basic event definitions, or does it necessitate new basic events? * Does the application necessitate a specialized probability model (e.g., time-dependent model, etc.)? * Does the application necessitate modifications to specific parameter values? * Does the application introduce new component failure modes? * Does the application affect the component mission times? * Does the application necessitate that the plant-specific (historical) data be taken into account, and can this be easily achieved by an update ol the previous parameters? Does the application involve a change which may impact parameter values, and do the present estimates reflect the current status of the plarit with respect to what is to be changed? Dependent Failure Analysis * Does the application introduce or suggest new common cause failure contributions? * Does the application introduce new asymmetries that might create subgroups within the CCF component groups? * Is the application likely to affect CCF probabilities? 4 Information from Section 3.3 of the EPRI "PSA Applications Guide" provided substantial input to this table. SRP 19-30 Table I11-1 (page 2 of 3) Questions to Assist in Establishing the Cause-Effect Relationship Human Reliability Analysis * Does the application involve a procedure change? * Does the application involve a new human action? * Does the application change the available time for human actions? * Does the application affect the human action dependency analysis? * Does the application eliminate or modify an existing human action? * Does the application introduce or modify dependencies between plant instrumentation and human actions? 0 Is the application concerned with events that have been screened from the model, either in whole or in part? 0 Does the application impact a particular performance shaping factor (PSF), or a group of PSFs, and are they explicitly addressed in the estimation approach (e.g., if the issue is to address training, is training one of the
