, construction, and maintenance of the RCS vent system providing assurance that it is able to perform its safety functions and that the integrity of the RCPB is maintained. 5. General Design Criterion 14 requires that all RCPB components be designed and constructed such that there is an extremely low probability that these components will fail and cause a primary leak or loss of coolant accident. The RCS vent system is an integral part of the RCPB that is designed to establish a controlled leakage path to vent gases from the RCS. Appropriate design and construction standards will ensure that in its static condition the RCS vent system will not leak, and in its dynamic condition will operate only when called upon to do so. Following GDC 14 will ensure that the integrity of the RCPB is preserved and that adequate core cooling is maintained. 6. General Design Criteria 17 and 34 require that onsite and offsite electric power systems be provided for all safety-related structures, systems, and components (GDC 17) and specifically for residual heat removal systems (GDC 34). The electric power systems 5.4.12-7 DRAFT Rev. 1 - April 1996 must have adequate independence, redundancy, and testability, and provide sufficient capacity and capability to assure that fuel and reactor coolant pressure boundary design limits are not exceeded, and that core cooling and containment integrity are maintained. The reactor coolant system vents require electric power to function properly. Meeting the requirements of GDC 17 and 34 will ensure that power is maintained to the vent system during accidents. This will enable the vent system to fulfill its safety function of venting gases from the reactor coolant system thereby ensuring that adequate core cooling is established and maintained. 7. General Design Criterion 19 requires that the plant design incorporate a control room from which emergency actions can be taken to maintain the plant in a safe condition under accident conditions. The
