o containment integrity. Meeting GDC 38 will help ensure that containment can fulfill its role as the final barrier against the release of radioactivity to the environment. 4. GDC 39 requires that the containment heat removal system be designed to permit appropriate periodic inspection of important components. The containment heat removal system is relied upon to minimize the duration and intensity of the pressure and temperature increase following a loss-of-coolant accident thus lessening the challenge to the containment barrier. Periodic inspection will verify the operability and integrity of the containment heat removal system and help ensure that it fulfills its role in precluding the release of radioactivity to the environment. 5. GDC 40 requires that the containment heat removal system be designed to permit appropriate periodic testing of important components. The capability of the containment heat removal system to reduce containment temperature and pressure is dependent upon the functionality of system components. Periodic functional testing of the containment heat removal system components validates the safety analysis assumptions regarding the system's effectiveness in reducing post LOCA temperature and pressure and provides assurance of operability and the capability to perform following a design basis accident. 6. GDC 13 requires that instrumentation be provided to monitor all expected parameters of normal operation, anticipated operational occurrences, and accidents to assure adequate reactor safety is maintained. Since containment plays a vital safety role, appropriate instrumentation, such as temperature and pressure, must be provided so that operators can verify containment is properly fulfilling its function. Meeting GDC 13 will help ensure that containment accomplishes its mission of precluding the release of radioactivity to the environment. 7. GDC 64 requires that the containment atmosphere be monitored for the release of radioactivity from
