Content:
products are entrained in the suppression pool and are unavailable for leakage from containment. Compliance with GDC 41 ensures that the suppression pool will adequately meet its post accident safety function of fission product cleanup. 2. GDC 42 requires that the system be designed to permit appropriate periodic inspection of important components. If taken credit for in the Chapter 15 Accident Analysis, the suppression pool is relied upon to entrain fission products following design basis accidents. Inspection of important components of the suppression pool will validate the safety analysis assumptions regarding the system's effectiveness in fission product cleanup and assure the integrity and capability of the system to remove fission products following a design basis accident. 3. GDC 43 requires that the system be designed to permit appropriate periodic testing of important components. The capability of the suppression pool to clean up fission products is dependent upon the functionality of system components. Examples of functional testing performed on the suppression pool system components include: drywell leak testing, vacuum breaker operability tests, vacuum breaker position indicator and alarm testing, and water level instrument testing. The periodic functional testing of the suppression pool system components validates the safety analysis assumptions regarding the system's effectiveness in fission product cleanup and provides assurance of operability and the capability to remove fission products following a design basis accident. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the 6.5.5-6 Revision 1 - March 2007 proposed alternatives provide an acceptable method of complying with the
