d occur before operation and during startup to functionally demonstrate that the overpressure protection system, as installed, meets all design requirements. 6. Technical Specifications. The technical specifications should specify appropriate limiting conditions of operation and inservice surveillance to ensure continued system reliability, including, for PWRs, specific limiting conditions of operation and testing of the LTOP 5.2.2-8 Revision 3 - March 2007 system as specified in NUREG-1430 through NUREG-1434, Generic Letters No. 82-16, 83-02, and 90-06. 7. TMI Action Plan Requirements. Section II.D.1 of the TMI Action Plan requires an applicant submit a plant specific report regarding relief valve (RV) and safety valve (SV) testing. Section II.D.3 of the TMI Action Plan requires that RVs and SVs be provided with direct valve position indication. Generic Letters No. 82-16 and 83-02 requires sections II.D.1 and II.D.3 be covered by technical specifications while NUREG -0737 section II.K.3.3 specifies reporting for section II.D.1 and II.D.3. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. GDC 15 requires that the reactor coolant system and associated auxiliary, control, and protection systems shall be designed with sufficient margin to assure that the design conditions of the reactor coolant pressure boundary are not exceeded during any condition of normal operation, including anticipated operational condition. The overpressure protection system maintains RCS pressure within acceptable design limits during certain analyzed transients. Application of GDC 15 to the overpressure protection system provides assurance that the RCPB will have an extremely low probability of failure during transients. 2. GDC 30 requires that the reactor coolant pressure boundary be designed, fabricated, erected and tested to the highest quality standards
