APPROVED:PLANT MANAGER DATE

RESPONSIBILITY

1. Instrument Supervisor (Test Director), for performing the test,analysis of data, and reporting of results.

2. Shift Foreman, for obtaining the proper clearance and maintaining safeoperating conditions during the test period. Also, the SFM isresponsible to supply personnel to perform verification.

FREQUENCY

The test may only be performed during plant shutdown (modes 5 or 6) when

the rod control motor-generators are not operating and the reactor tripbreakers are available for test. The Technical Specifications, Tables4.3-1 and 4.3-2 require that the functional test be performed on a normalrefueling outage basis.

SCOPE

I The purpose of the routine test is to determine that the manually operatedswitches for initiating and blocking reactor protection and engineeredsafeguards functions are operative and will perform the actions for whichthey were designed. These functions are as follows:

1. Manual Reactor Trip

2. Containment Isolation Phase B

3. Safety Injection

4. Containment Isolation Phase A, Actuate Trains A&B

DISCUSSION

The manually operated switches involved in the initiating, blocking and/orresetting of protection and safeguards functions work in any or all of fourways. These are: 1) contacts directly in the circuitry of the equipment,2) contacts directly to the master relays in the SSPS, 3) contacts to theelectronic logic circuitry in the SSPS and 4) contacts directly to theunlatching coils of the slave relays, as follows:

1. The correct functioning gf the contacts directly in the circuitry ofequipment is determined by observing the actual operation of theequipment.

2. The correct functioning'of the contacts that are directly involved inmaster relay operation is determined in the following manner. Thereare two ways that a slave relay can be activated. One is through themaster relay with which it is associated and the other a parallelcircuit through the Safeguards Test Cabinet. As the slave relays areactually energized during the use of the Safeguards Test Cabinet, itis therefore only necessary to prove the manual switch circuitrythrough the master relay to or beyond the common points of the twoparallel circuits. This is done by monitoring the bottom coil(terminal 2) of the slave relays in question with the output relaycabinet in the "TEST" mode and the master relay selector in the "OFF"position.

3. The correct functioning of the contacts that introduce a signal to theelectronic logic is verified by manually introducing a signal from thecontrol room switches and determining that the proper potential isreceived at the logic input. Operation of the logic is tested usingthe semi-automatic tester in the SSPS (STP I-16A or I-16D) whichapplies the same input signals to the logic as the control roomswitches.

4. The correct functioning of the contacts that unlatch the slave relaysis verified by observing that the proper unlatching potential isapplied across the unlatching coil. 'The physical unlatching of thecoils is demonstrated during individual slave relay testing throughthe Safeguards Test Cabinet, or other testing.

As this test involves only the two basic logic conditions of "True orFalse" it is not necessary to use calibrated voltmeters. The values givenin the procedure are referenced to the logic state rather than to precisevoltages.

DOCUMENTATION AND REPORTING

1. Sumary Sheet

A summary sheet is provided which is intended to serve as a "shopfollower" for the test. This sheet shall be filled out each time thetest is performed, and shall be filed with the data sheet package forthe test. The sumary sheet has several basic functions:

a. To allow the technician and inspector (if any) to documentcertain important findings and/or the completion of certainimportant steps in the procedure. In particular, provision ismade on the form to document the completion of the importantsteps in the removal from service and reinstatement.

At the bottom of the form is a section entitled "Summary of MajorFindings." This should be filled out by the technician, and isintended to be a brief summary of important, unusual orunexpected items, such as breaker contact remains closed, switchreplaced, Plant Problem Report filed, etc. This is intended onlyto be a convenient summary to aid the reviewer of the test. Itis not intended to be a comprehensive test report. More detailedinformation would be found on the test data sheets, maintenancehistory cards, Plant Problem Reports or in other special reportsprepared for the test.

b. To assist the reviewer(s) of the test results by directing theirattention to the important findings. The tests are ordinarilyreviewed shortly after completion by a cognizant supervisor whoapproves the data sheets and maintenance cards.

2. Data Sheets
