Content:
injection, the types and methods of construction (e.g. the use of double wall pins versus single walled pins to improve integrity) of start-up neutron sources, the types of neutron detection equipment (e.g. in core neutron detectors) and features provided to minimize neutron irradiation of plant structures and components. 5.2.3 REACTOR COOLANT PRESSURE BOUNDARY MATERIALS – as it relates to the material specifications provided to reduce ORE (e.g. low cobalt content), chemistry controls to minimize corrosion and reduce ORE (e.g. Electric Power Research Institute (EPRI) primary water chemistry guidelines and zinc injection), thermal hydraulic design features provided to limit erosion (e.g. limiting flow rates, or the use of baffles) and fabrication techniques, such as processes to ensure smooth surfaces resistant to erosion or the deposition of material and to minimize contamination. 5.2.4 REACTOR COOLANT PRESSURE BOUNDARY INSERVICE INSPECTION AND TESTING – as it relates to the methods and features provided to reduce ORE due to inspections such as: reducing inspection frequencies, improving access to SSCs, using improved inspection techniques. 5.2.5 REACTOR COOLANT PRESSURE BOUNDARY LEAKAGE DETECTION – as it relates to the radiation monitoring systems, types of detectors and specified sensitivity, provided for leakage detection to ensure the integrity of the Reactor Coolant System (RCS), and to minimize contamination of the facility and reduce ORE through early detection of leaks. 5.3.1 REACTOR VESSEL MATERIALS - as it relates to the material specifications provided to reduce ORE (e.g. cobalt content). 5.4 REACTOR COOLANT SYSTEM COMPONENT AND SUBSYSTEM DESIGN – as it relates to the features provided to limit or reduce the build up of radioactivity in tanks, heat exchangers, and related components connected to the RCS), and features provided to limit ORE, minimize contamination of the facility and reduce waste generation from these potential radiation sources.
