olant Pressure Boundary," requires (in part) that the RCPB be designed, fabricated, erected, and tested in a manner that provides assurance of an extremely low probability of abnormal leakage, rapidly propagating failure, or gross rupture.8 7. General Design Criterion 15 (GDC 15), "Reactor Coolant System Design," requires (in part) that the reactor coolant system (RCS) and associated auxiliary, control, and protection systems be designed with sufficient margin to ensure that the design conditions of the RCPB are not exceeded during any condition of normal operation, including anticipated operational occurrences.9 8. General Design Criterion 30 (GDC 30), "Quality of Reactor Coolant Pressure Boundary," requires (in part) that: a. Components that are part of the RCPB be designed, fabricated, erected, and tested to the highest quality standards practical; and b. Means be provided for detecting and, to the extent practical, identifying the location of reactor coolant leakage.10 9. General Design Criterion 31 (GDC 31), "Fracture Prevention of Reactor Coolant Pressure Boundary," requires (in part) that: a. The RCPB be designed with sufficient margin to ensure that when stressed under operating, maintenance, testing, and postulated accident conditions the boundary behaves in a nonbrittle manner and the probability of rapidly propagating fracture is minimized; and b. The design reflect consideration of service temperatures and other conditions of the boundary material under operating, maintenance, testing, and postulated accident conditions, including the uncertainties associated with determining: (1) Material properties; (2) The effects of irradiation on material properties; (3) Residual, steady state, and transient stresses; and (4) Size of flaws.11 10. General Design Criterion 32 (GDC 32), "Inspection of Reactor Coolant Pressure Boundary," requires (in part) that components that are part of the RCPB be designed to permit: a. Periodic inspection and testing of important
