fied in Subsection II. The NRC staff uses the procedures below during the construction permit review to determine whether the design criteria and bases and preliminary design in the preliminary safety analysis report (SAR) meet the acceptance criteria in subsection II. For review of operating license (OL) applications, the procedures verify that the initial design criteria and bases have been 10.2-6 Revision 3 - March 2007 appropriately implemented in the final design detailed in the final SAR. These procedures should be followed for review of a DC or COL application. The review procedures for COL, DC, or OL applications determine that the content and intent of the applicant’s technical specifications agree with the requirements for system testing, minimum performance, and surveillance developed as a result of the staff’s review. The specified review procedures are for a typical TGS. Any variance in the review to account for a proposed unique design will ensure that the system meets the criteria of subsection II. The reviewer evaluates the TGS, subsystems, and components of the unit that are considered essential for the safe integrated operation of the reactor facility. 1. The reviewer confirms that the system description and the piping and instrumentation diagrams (P&IDs) provided in the SAR show the TGS. The general arrangement of the TGS and associated equipment with respect to safety-related SSCs is noted. 2. The reviewer verifies the adequacy of the control and overspeed protection system and determines the following: A. Support systems, subsystems, control systems, and alarms and trips will function for all abnormal conditions, including a single failure of any component or subsystem, and will preclude an unsafe turbine overspeed. The design of the in- depth defense provided by the turbine generator protection system to preclude excessive overspeeds should include diverse protection means. B. For normal speed-load control, the speed governor action of the
