actor coolant, containment sump water, and containment atmosphere without clearing the CIS or SIS. 5. The Electrical Engineering Branch (EELB), under SRP Section 8.3.1, ensures that power supplies are available to all remotely operated valves in the PAS, after detection of an accident which requires containment isolation, assuming a concurrent loss of offsite power. CMEB coordinates reviews related to this system that are performed by the following branches as part of their primary review responsibilities: Radiological Assessment Branch (RAB), under 9.3.2-3 DRAFT Rev. 3 - April 1996 SRP Section 12.3, reviews the potential personal radiation exposure during post-accident sampling. Effluent Treatment Systems Branch (ETSB) reviews the ventilation systems which may be operating during post-accident sampling and the sampling and monitoring systems for radwaste processing systems under SRP Sections 11.3 and 11.5, respectively. Containment Systems Branch (CSB), under SRP Section 6.2.4, verifies that remotely operated containment isolation valves in the PSS and PAS are designed to close on a containment isolation signal (CIS) or safety injection signal (SIS). Instrumentation and Control Systems Branch (ICSB), under SRP Section 7.3, verifies that an override capability exists for the containment isolation valves which will be used for post-accident sampling of the reactor coolant, containment sump water, and containment atmosphere without clearing the CIS or SIS. Power Systems Branch (PSB), under SRP Section 8.3.1, ensures that power supplies shall be available to all remotely operated valves in the PAS, after detection of an accident which requires containment isolation, assuming a concurrent loss of offsite power. Equipment Qualification Branch (EQB), under SRP Section 3.11, verifies that those valves which are inaccessible during an accident are environmentally qualified to ensure operability under accident conditions. Auxiliary System Branch (ASB), under SRP Section
