What are the elements of 10 CFR 50 Appendix A?
- General Design Criteria
- Definitions: LOCA, Single Failure, Aticipated Operational Occurances
- 1-5: Overall Requirements
- 10-19: Multiple Fission Produc Barriers
- 20-29: Protection and Reactivity Control
- 30-46: Fluid Systems
- 50-57: Reactor Containment
- 60-64: Fuel and Reactivity Control
-
Define LOCA
Postulated accident resulting from loss of reactor coolant at a rate greater than what the makeup system can replenish
-
Define Single Failure
multiple failures resulting from a single occurence which resuls in the loss of capability of a component to perform its intended safety function
-
Define Anticipated Operational Occurances
- conditions of normal operation which are expected to occur more than once during the life of the plant
- Examples: Loss of power to all reciculation pumps, tripping of the turbine generator set, Isolation of the main condenser, loss of all offsite power
-
Define Safety Related
- SSC's designed to remain functional to assure required safety function
- 1: Integrity of RCS boundary
- 2: Capability to shutdown the reactor and maintain safe shutdown
- 3: Capability to prevent or mitigate consequences of accidents which could result in offsite exposures
-
