SYSTEMATIC EVALUATION'ROGRAM REVIEW OF NRC SAFETY TOPIC III-1 ASSOCIATED WITH THE ELECTRICAL, INSTRUMENTATION, AND CONTROL PORTION OF THE CLASSIFICATION OF STRUCTURES, COMPONENTS, AND SYSTEMS FOR THE GINNA NUCLEAR POWER PLANT

1. INTRODUCTION Some of the SEP plant structures, systems, and components may not be designed to withstand the effects of a safe shutdown earthquake and remain functi onal . In some cases, systems and components important to safety may not be designed, fabricated, erected, and tested to quality standards commensurate with their safety function.

The compilation of the major systems required for design basis events (DBE) and for safe shutdown of the plant is submitted in support of NRC Safety Topic 111-12. This safety topic addresses whether the major systems identified meet current quality standards.

2. REVIEW GUIDELINES The objective of this review is to identify only the major elec-trical, instrumentation and control systems (EICS) required for DBE and for safe shutdown of the plant. This identification is to be performed when reviewing each NRC safety topic. A detailed search is not to be made to identify all required systems for DBE and for safe shutdown.

lO 3.2 REACTOR PROTECTION SYSTEMS The following reactor protection systems (reactor trip channels) are required for DBE and safe shutdown:

1. High nuclear flux (power range)

2. High nuclear flux (intermediate range)

3. High nuclear flux (source range)

4. Overtemperature hT

5. Overpower hT

6. Low RCS pressure

7. High pressurizer pressure

8. High pressurizer water level

9. Low reactor coolant flow

10. Turbine trip

11. High containment pressure

12. Low steam generator pressure

13. Low steam generator level

14. Manual trip 3.3 ADDITIONAL SYSTEMS In addition to the ESF and RPS, the following systems are requir-ed for DBE and safe shutdown:

1. Auxiliary feedwater system

2. Service water system

3. Component cooling water system

4. . Residual heat removal system

5. Chemical and volume control system

6. Offsite power system

7. Control room systems

8. Emergency power (a-c and d-c) and control power for the above systems and components
