Content:
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 reactor coolant vents are remotely operable from the control room such that the vent system can properly fulfill its safety function of venting primary system gases during an accident. Compliance with GDC 19 will provide assurance that control room operability is preserved such that the reactor coolant system vents can be operated during an accident thereby ensuring that core cooling is maintained. 8. General Design Criterion 36 requires that emergency core cooling systems (ECCS) be designed to allow periodic inspections to assure the integrity and capability of these systems to carry out their safety functions is maintained. The reactor coolant system vents are part of the ECCS in that they eliminate gases from the primary system which could otherwise inhibit ECCS natural circulation or pump operation. Conforming with GDC 36 will ensure that the operability of the reactor coolant system vents is maintained throughout the life of the plant so that core cooling will not be interrupted by the evolution of gas during an accident. III. REVIEW PROCEDURES The procedures below are used during the construction permit (CP) review to assure that the design criteria and bases and the preliminary design as set forth in the Preliminary Safety Analysis Report meet the acceptance criteria given in subsection II. For operating license (OL) reviews, the procedures are utilized to verify that the initial design criteria and bases have been appropriately implemented in the final design as set forth in the Final Safety Analysis Report. The OL review also includes the proposed technical specifications, to assure that they are adequate in regard to limiting conditions of operation and periodic surveillance testing. The reviewer will select and emphasize material from this SRP section, as
