230 kV Switchyard Systems 16.8-2 16.8 ELECTRICAL POWER SYSTEMS 16.8-2 230 kV Switchyard Systems COMMITMENT APPLICABILITY:

The following switchyard equipment shall be in its normal alignment.

/

a.

Switchyard Unit 1 PCBs 14, 15, 17, and 18 including their associated manual disconnects, current transformers, interconnecting bus, and support structures (EBA system),

b.

Switchyard Unit 2 PCBs 20, 21, 23, and 24 including their associated manual disconnects, current transformers, interconnecting bus, and support structures (EBA system),

c.

Busllnes 1A, 1 B (from main stepup transformers to switchyard unit PCBs), including their associated motor operated disconnects, coupling capacitor voltage transformers, interconnecting bus, and support structures (EBA system),

d.

230 kV Switchyard Systems 16 8-2 REMEDIAL ACTIONS A.

CONDITION Switchyard equipment not in normal COMMITMENT alignment.

A.1 REQUIRED ACTION Return switchyard equipment to normal COMMITMENT alignment.

COMPLETION TIME In accordance with the Electronic Risk Assessment Tool TESTING REQUIREMENTS None BASES REFERENCES Effective implementation of the Maintenance Rule, 10 CFR 50.65, requires the continuous assessment of systems determined to be risk significant in the protection against core damage or radiation release. It has been determined through probabilistic risk assessment (PRA) numerical methods that switchyard systems are risk significant from the standpoint of causing or being able to recover from Loss of Offsite Power events. This SLC serves two purposes. It defines the risk significant portions of the switchyard.

It also provides a method of tracking the switchyard systems for the purposes of supporting 1 O CFR 50.65
