system shall be designed in accordance with the requirements of Branch Technical Posi- tion RSB 5-2 attached to this SRP section (Ref. 3). The LTOP system shall be operable during startup and shutdown conditions below the enable temperature defined in paragraph B.2. of RSB 5-2. 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 of this SRP section. For operating license (OL) applications, the procedures are used 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 and in the report on overpressure protection. The latter report is required by the ASME Code (Ref. 2) and is used as the basis for many of the individual review steps outlined below during the OL review. 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 following steps are taken by the SRXB reviewer in determining that the acceptance criteria of subsection II have been met. These steps should be applied to CP and OL reviews as appropriate. Previously reviewed designs may be used as a guide; however, the reviewer must verify that any changes are justified. 5.2.2-3 Rev. 2 - November 1988 1. The piping and instrumentation diagrams are examined to determine the number, type, and location of the safety and relief valves in both the primary and secondary systems, and of discharge lines, instrumentation, and other components. 2. All other functions of the components, instruments, or controls used for overpressure protection and the interfaces with all other systems are identified. The effects of these other functions or systems on operation of the
