are isolated from, and independent of, one another. 3. The main steam stop, control, reheat stop, and intercept valving arrangements and valve closure times are reviewed to ensure that no single valve failure can disable the overspeed control function. 4. The extraction steam valving arrangements and valve closure times are reviewed to see that stable turbine operation will result after a TGS trip. 5. The capability for testing of essential components during TGS operation is reviewed. 6. The proposed inservice inspection program for essential speed control valves is reviewed to verify that it includes the provisions of item 5 of subsection II of this SRP section. 10.2-7 DRAFT Rev. 3 - April 1996 7. The RAB PERB reviews the expected radiation levels around the TGS and the degree 28 of access to TGS components during operation and the MEB EMEB reviews the quality 29 and seismic classification as indicated in subsection I of this SRP section. 8. If there are safety-related systems or portions of systems located close to the TGS, the physical layout of the system is reviewed to assure ensure that protection has been provided from the effects of high and moderate energy TGS piping failures or failure of the connections from the low pressure turbine section of the main condenser. The means of providing such protection will be given in Section 3.6 of the SAR, and the procedures for reviewing this information are given in the corresponding SRP Sections. For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM)
