NUREG-0800 U.S. NUCLEAR REGULATORY COMMISSION STANDARD REVIEW PLAN BRANCH TECHNICAL POSITION 11-6 POSTULATED RADIOACTIVE RELEASES DUE TO LIQUID-CONTAINING TANK FAILURES REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of the effectiveness of radwaste systems and health physics in modeling radiation exposure scenarios and in confirming compliance with dose acceptance criteria. Secondary - Organizations responsible for the review of site geology and hydrology characteristics and the use of conceptual models in surface and groundwater transport; civil engineering in evaluating building plant structures and foundations; and mechanical engineering for the review of the plant’s structures, systems and components and design of mitigating features. A. Background During normal operation, nuclear power plants generate radioactive materials, as fission and activation products, which are present in primary coolant and secondary coolant and steam. Primary and secondary coolants are processed by the liquid waste management system (LWMS). The LWMS is designed to ensure that liquids and liquid wastes produced during normal operation, including anticipated operational occurrences, are handled, processed, recycled as coolant, or released in accordance with relevant U.S. Nuclear Regulatory Commission (NRC) regulations. The LWMS is comprised of permanently installed plant systems and mobile processing equipment. Typically, such systems include tanks, piping, pumps, valves, filters, demineralizers, and additional equipment that are
