Signatures are hot required for these re-verifications.
3.7 Communications between the Test Technician, Operator at the CEDM control panels, and the Control Room must be established prior to the start of the test, and maintained throughout the duration of the test.
3.8 If the Unit is shut down and a SCRAM signal is present, contact the Instrument Department and have them remove the trip by simulating a running condition at the Plant Protection Cabinets to allow operation of the Reactor Breakers.
3.9 Test Equipment 3.9.1 Electronic Timer or Oscillograph Recorder 3.9.2 DMM (Digital Multimeter) 3.9.3 Switches, leads, hand tools, etc.
3.10 Measuring and Test Equipment (M&TE) to be used for this test shall have a current calibration history, have an accuracy better than the allowable accuracy of the device to be calibrated, and be NBS traceable.
3.11 This test will normally be performed with the breaker in the "racked in" position, but can be performed in the "In Test" position. This will keep the circuitry intact to the undervoltage coil with the diede in the coil circuit.
4.0 PRECAUTIONS 4.1 In the event any unanticipated conditions occur during testing, the technician shall immediately notify the Control Operator.
4.2 Receiving approval to begin testing does not, in any way, obviate the responsibility of the technician to determine for himself that it is prudent and safe to begin work.
4.3 In the event the test data does not meet the acceptance criteria, the Control Operator and the applicable Supervisor shall be notified immediately. Under no circumstances shall the device be returned to service withoutthe Control Operator's approval.
4.4 Observe the Work Authorization Holders' responsibilities under Operating Instruction S023-0-13.
4.5 In conducting the activities of the procedure, various levels of circuit voltags wi. b: energized.
Exercise caution and conform to the guidelines specified in References 2.8 and 2.9 concerning maintenance activities on energized electrical circuits.

4.7 The tie breaker (TCB-9) shall not be tested if only one CEDM MG s 1 in service.
4.8 Necessary steps shall be taken to prevent any unscheduled trips or damage to equipment.
5.0 CHECK-OFF LIST(S) 5.1 None 6.0 PROCEDURE 6.1 Verify communications as set forth in step 3.7. Enter the verification signature on the Data Record, Attachment 8.3.
6.2 Verify the proper plant status and CEDM lineup with Operations personnel.
Any deviation from normal plant status and CEDM lineup will be noted in the Remarks section of the Data Record, Attachment 8.3.
6.3 Acceptance Criteria 6.3.1 With timing leads connected to the auxiliary switch (pallets) contacts and the breaker installed in the cubicle, the maximum time response shall be 100 msec, per CE guidelines.
6.3.2 If the time is >82 msec and <100 msec, the Supervisor of I&C Electrical Engineering sEall be notified immediately for the purpose of investigating possible degradation of the tripping devices or breaker.
6.3.3 If the time is >100 msec, the breaker shall be declared inoperable and the Cognizant Supervisor and Control Operator shall be notified immediately.
NOTE:
The 82 msec time is based upon the maximum average test time that was noted during testing by SCE Apparatus Division in concert with GE.
This time includes the extra time added using the auxiliary contacts.

6.4.3 With the timing device connected, remove the power to the undervoltage circuit for the selected breaker, and time from loss of voltage to the breaker opening. Have the breaker closed and repeat the trip twice more. Record the three times on the Data Record, Attachment 8.3.
6.4.4 Return the breaker to the closed or "As Found" condition.
CAUTION ONLY ONE BREAKER AT A TIME MAY BE TRIPPED.
THE BREAKER UNDER TEST MUST BE RECLOSED AND RETURNED TO NORMAL BEFORE TESTING MAY PROCEED ON ANY OTHER REACTOR BREAKER.
6.5 Response Time Testing - Shunt Trip Device 6.5.1 Set up the timing device to be able to time from the initiation of the signal to the shunt trip device to the breaker tripping (opening).
6.5.2 Use the auxiliary contacts (pallets) to time opening of the breaker. Connect test leads to the terminal blocks on the rear of the switchgear per Attachment 8.2.
6.5.3 Initiate a trip signal to just the shunt trip device by closing the circuit, identified in Attachment 8.1 for the selected bre'-
interval between initiation of thc trip signal and the breaker.tir nrjng (opening).
