1 Technical Specification Requirements:

2.1 - ' Section 15.4, Table 15.4.1-1, Items 1,4;5,6',7,8,11, and 12.

2.2 Perform this test'conthly (every four' weeks).

g' ~ '

3.0~ CONDITIONS.

'May be performed at any plant power from cold shutdown =to full power.

j: Permissive buttons must be used above or below certain power levels. ,

j /4.0 PRECAUTIONS' i 4 .1 '- Test only one train ("A" or "B") at a. time.

4. 2 D'u ring at-power testing, only one auto shunt trip panel cell-cubicle ("A" or "B") is to be opened at a time.~

. '4. 3 ' All test switches must be returned to normal before testing the.-

t- other train.

4.4 After testing is completed in either-train and before the trip

.. breakers are returned'to normal configurations, check that all p the RT relays are energized by observing the relay " button"'is 1 pulled in.

' 4 . 5 .. After-testing all trip combinations of relays listed under each ~

protective. function, verify that operation of a single relay will not cause the trip to occur by operating each relay individually and

[. noting no trip occurs.

l 4.6- Steps 5.2.14 and 5.2.15 shall not be perfonmed'if ang of the following systems are considered inoperable:

5.3.31 Conduct a continuity check of the following checkoff auxiliary feedwater pump auto start relays if they are deenergized. Test points are located on the logic test panel.

LCAB TP1 to Common %320 ohms LCBB TP2 to Common $320 ohms

ICP 2.3 Page 27 Checkoff 5.3.32 Close reactor trip breaker "B" from the main control board.

5.3.33 Open bypass breaker "B" from the Train "A" logic test panel.

5.3.34 Place bypass breaker "B" in the pullout position.

5.3.35 Notify DSS upon completing this test.

(DSS)

NOTE 1: Reactor trip breaker "A" will trip on this step. Do not reclose this breaker until Step 5.2.32. Verify loss of voltage to the undervoltage coil for all other Train "A" trip combinations by use of the white light on the Train "A" test panel.

NOTE: 2: Reactor trip breaker "B" will trip on this step. Do not

reclose this breaker until Step 5.3.32. Verify loss of voltage to the undervoltage coil for all other Train "B" trip combinations by use of the white light on the Train "B" test panel.
