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

,D. H. Laudenbach EG8G, Inc., Energy Measurements Group San Ramon Operations 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 functional.

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.
