ions 9.5.1, 16.0, and 17.0, respectively. For those areas of review identified above as being part of the primary review responsibility of the other branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary branches. II. ACCEPTANCE CRITERIA Acceptability of the design of the turbine generator system, as described in the applicant's Safety Analysis Report (SAR), is based on the General Design Criteria and the other specific criteria listed below, and on the similarity of the design to that of plants previously reviewed and found acceptable. The design of the turbine generator system is acceptable if the integrated design of the system meets the requirement of General Design Criterion 4 as related to the protection of structures, systems, and components important to safety from the effects of turbine missiles by providing a turbine overspeed 10.2-2 Rev. 2 - July 1981 protection system (with suitable redundancy) to minimize the probability of generation of turbine missiles. Specific criteria necessary to meet the requirements of GDC 4 are as follows: 1. A turbine control and overspeed protection system should be provided to control turbine action under all normal or abnormal'operating conditions, and to assure that a full load turbine trip will not cause the turbine to overspeed beyond acceptable limits. Under these conditions, the control and protection system should permit an orderly reactor shutdown either by use of the turbine bypass system and main steam relief system or other engineered safety systems. The overspeed protection system should meet the-single failure criterion and should be testable when the turbine is in operation. 2. Turbine main steam stop and control valves and reheat steam stop and intercept valves should be provided to protect the turbine from exceeding set speeds and to protect the reactor system from abnormal surges. The reheat stop and
