If practical, de-energi:s all electrical equipment. Red-ug breakers and r.vitches as apprep l

NOTE: Some equipment may be powered from more than one source. lbTT1ALS  !

- a.

Check all equipment wid a meter to ecsure it is de-energized before working on it,

b. Observe proper working clearances during work, refer to 1.5.1 i of the Wisconsin Electic Safety Manual.

2.

If it is necessary to work on energized equikent, perfor:n 6e fouowing ,

applicable steps. Mark 'N/A' for 6ose items that do not apply to the evolution.

NOTE: Low-voltage gloves may be worn in lieu of high-voltage gloves while l working on conductors or equipment which are, or may become, energized i

st 130 V or less. l 2.

Ensure approved high-voltage gloves are obtained and air tested prior to use.

b. Ensure approved low-voltage gloves are obtained and air tested prior to use.

MSS #: ADMINISTRATOR.

INITIATOR: ISSUE MANAGER:

NUMBER OF OPEN ACTIONS: 2 NUMBER OF CLOSED ACTIONd: v Alarm Response Contrary To What Was Anticipated Per The Procedure DESCRIPTION:

When the DC control power to bus 2B03 was de-energized, the Unit 2 Common Critical Control Power Failure alarm (Window CO2 F 4-1) was not received. The previous step of the controlling procedure to de-energize the control power indicated this alarm should have been received.

i Significance: Unanticipated response contrary to procedure.

Corrective Actions: Reviewed drawings and determined the Unit 2 Common Critical Control Power Failure alarm (Window CO2 F 4-1) should not be received when the 2B03 DC Control Power is de-energized. The 2B03 fuse monitor relay ( 2B 03 -74 FM) inputs to the alarm and only monitors the DC Control Power to 2B03 lockout scheme which has a different supply than the overall bus control power.

There was no automatic control action associated with this alarm. The .

lack of the alarm did not affect the operability of safety related l equipment. An evaluation of the appropriateness of this response is questioned in one of the action items. If that appropriateness is determined to be different than what is stated, this will be updated.

This is not considered reportable.
