g., control rods, control rod drives, and boron injection system). o The control room, including its associated equipment and all equipment needed to maintain the control room within safe habitability limits for personnel and safe environmental limits for vital equipment. o The primary and secondary reactor containment. e. support systems that are needed to fulfill the functions described in items 1.c and 1.d above, including but not limited to component cooling, service water, Class 1E electrical systems, fuel systems, seal water systems (such as those for reactor coolant pumps), and supporting subsystems (including the auxiliary systems for the onsite electric power supplies), and diesel fuel support systems; f. systems or portions thereof that are needed for (1) monitoring and (2) actuating systems, as described further in Regulatory Guide 1.151, “Instrument Sensing Lines” (Ref. 10) , including all electrical and mechanical devices and circuitry between the process and the input terminals of the actuator systems involved in generating signals that initiate protective action; and g. systems, other than radioactive waste management systems, not covered by items 1.a through 1.f above that contain or may contain radioactive material and the postulated failure of which would result in conservatively calculated potential offsite doses that are more than 0.005 Sievert (0.5 rem) to the whole body or its equivalent to any part of the body or total effective dose equivalent (TEDE), as applicable. Design guidance for radioactive waste systems can be found in Regulatory Guide 1.143, “Design Guidance for Radioactive Waste Management Systems Structures and Components Installed in Light- Water-Cooled Nuclear Power Plants” (Ref. 11). Guidance for dose calculations can be found in Regulatory Guide 1.3, “Assumptions Used for Evaluating the Potential Radiological Consequences of a Loss-of-Coolant Accident for Boiling-Water Reactors” (Ref. 12), Regulatory Guide 1.4,
