FUN'CTIONAL TEST SSPS Train A, Reactor Trip Breaker UV Coil PURPOSE 1.1 The purpose of this procedure is to verify the operability of the Reactor Trip Breaker under voltage (UV) coil from SSPS Train A.

2.0 REFERENCES

2.1 Solid State Protection System Manual.

2.2 Wiring Diagrams:

203688, 222885, 224305 3.0 PRECAUTIONS 3.1 Test conditions must be applied to only Train A.

A reactor trip will occur if both trains have a general warning condition Therefore, it is extremely important that the doors to only one train at a time are open, to preclude the introduction of test conditions into both trains.

3.2 Test conditions may be applied to one train using its built-in testers, while the opposite train is used to maintain the plant protection and provide data to the demul-tiplexers.

If in the process of testing, malfunctions are detected, they can be isolated by carefully following the

~rocedures in Section 6 of the Solid State Protection Manual.

3.3 This procedure must be completed in the sequence given to ensure successful completion.

4.0 LIMITATIONS AND ACTIONS 4.1 If, at any time during the performance of this test, there is any reason to suspect that the test equipment being used may not be performing properly, a comparison check shall be performed with a similar device or the device shall be checked for calibration against a standard.

This shall be done prior to taking any other corrective action~

4.2 If, during the performance of this test, the "As Fou1'd" data does not meet the requirements of the specified accuracy, the Job Supervisor shall be notified immediately and IC-14.1.001 shall be performed.

FUNCTIONAL TEST SSPS Train A, Reactor Trip Breaker UV Coil 4.0 LIMITATIONS AND ACTIONS (continued) 4.3 If, during the performance of this procedure, the required status indication cannot be obtained, the Job* Supervisor shall be notified immediately.

Exceptions to the required innication, due to plant conditions at the time of the test, may be made by the Job Supervisor.

Any exceptions of this nature must be indicated and explained in the Remarks section of this procedure.

4.4 An entrv will be made in the Remarks section of this procedure indicating any deficiency and the correcti~re action taken.

5.0 TEST EQUIPMENT None Required 6.0 PREREQUISITES 6.1 The individual assigned to perform this procedure is qualified to do so in accordance with Solid State Protection System Qualification Card 2.6.

Supervisor 6.2 The Senior Shift Supervisor/Shift Supervisor has granted permission to perform this procedure.

Senior Shift Supervisor/Shift Supervisor Date/Time 6.3 The Control Operator is aware of all of the alarms and indications that will result from the performance of this procedure.

Control Ooerator 6.4 Quality Control shall be present for the performance of this procedure.

7.0 SALEM GENERATING STATION TECHNICAL DEPARTMENT (I&C)

FUNCTIONAL TEST SSPS Train A, Reactor Trip Breaker UV Coil SYSTEM LINE-UP.

7.1 The following conditions must be established and/or verified by the Control Operator.

7.1.1 Reactor Trip Bypass Breaker B is open and in the Racked Out position.

7.1.2 Safeguard actions which are being blocked by virtue of having been RESET from the Control Bezel will be re-initiated at the completion of this test if the necessary logic signal is present.

The Safeguard actions involved are:

1.

Containment Spray

2.

Phase A Isolation

3.

Phase B Isolation

4.

Feedwater Isolation

5.

Containment Ventilation Isolation from Safety Injection signal Control Operator 8.0 INSTRUCTIONS INITIALS 8.1 Verify the fo~lowing Solid State Protection System Warnings Lamps are Off.

8.1.1 General Warning Lamp - Train A 8.1.2 General Warning Lamp - Train B 8.2 Depress the following.General Warning Lamps and verify the Lamp Lights, and then remains OFF.

8.2.1 General Warning Lamp - Train A 8.2.2 General Warning Lamp - Train B 8.3 Record UV Coil Voltage Meter Reading.

F.equired 43 VDC +/- 2 VDC (when shutdown 0 VDC +/- 2 VDC)

As Found 8.4 On the Output Relay Test Panel, place the Mode Selector Switch in the Test position.

8.5 Verify the Operate Lamp is not lit.

FUNCTIONAL TEST SSPS Train A, Reactor Trip Breaker UV Coil 8.0 INSTRUCTIONS (continued) 8.6 Verify the General Warning Lamp is lit.

8.7 On the Logic Test Panel, place the Input Error Inhibit switch* to the Inhibit position.

8.8 Verify Reactor Trip Breaker A is CLOSED (if Reactor Trip Breaker is open have the Control Operator CLOSE Reactor Trip Breaker A) 8.9 Omit steps 8.10, 8.18 and 8.19 if Reactor is tripped.

Tripped~~~~~-

Operational -------

8.10 Have the Control Operator rack in and close Reactor By-pass Breaker A, and verify that the breaker is in Operate position and its ~ight is illuminated.

INITIALS CAUTION Reactor By-pass Breaker A must remain energized for the duration of the manual testing, otherwise a Reactor Trip will occur.

8.11 At the LOGIC TEST Panel place the LOGIC A Test Switch in Position 7.

(Pressurizer High

.Pressure Trip).

8.12 In the MANUAL INPUT FUNCTION TEST portion of the LOGIC TEST PANEL, depress and hold any TWO pushbuttons.

8.13 At the Control Board, verify that Reactor Trip Breaker A is OPEN.

8.14 Verify the UV COIL VOLTAGE meter indicates approximately 0 VDC.

8.15 Release the pushbuttons depressed in Step 8.12.

8.16 Place the LOGIC A Test Switch in the OFF position.

8.17*Have the Control Operator close the Reactor Trip Breaker A.

8.18 Have the Control Operator OPEN Reactor By-pass Breaker A.

FUNCTIONAL TEST SSPS Train A, Reactor Trip Breaker UV Coil 8.0 INSTRUCTIONS (continued) 8.19 Have the Control Operator rack Out Reactor By-pass Breaker A.

8.20 Verify that the general warning test LED for SSPS Train A is extinguished in both Train A and Train B.

8.21 Have the Control Operator reinstate the FLUX TRIP MANUAL Blocks from the Control Board.

NOTE INITIALS The pushbutton must be pushed even when BEZEL block light is li~. (NO blocks can be applied if their permissives are not present, therefore, only those permitted will be set.)

8.21.1 Block Source Range - Train A pushed.

8.21.2 Block Intermediate Range - Train A pushed.

8.21.3 Block Power Range - Train A pushed.

CAUTION The Flux Trip Manual Blocks must be reinstated prior to placing the input error inhibit switch in the normal position.

8.22 Place the MODE Selector switch in the OPERATE position.

8.23 Actuate the following MANUAL BLOCKS using the pushbuttons on the Control Board.

No blocks can be applied if their permissives are not present; therefore, only those permitted will be set.

a.23.1 Pressurizer Safety Injection.

8.23.2 Steamline Pressure Safety Injection.

NOTE INITIALS Safeguard actions which are being blocked by virtue of having been R.ESET from the Control Bezels will be re-initiated at this time if necessary logic signal is present.

The safeguards actions involved are:

a.

Containment Spray

b.

Phase A Isolation

c.

Phase B Isolation

d.

Feedwater Isolation

e.

Containment Ventilation Isolation from Safety Injection Signal.

Inform the Control Operator of this condition.

Control Operator 8.24 Place the Input ERROR Inhibit switch in the NORMAL position.

8.25 Have the Control Operator reset all unwanted safeguards actions which were re-initiated as a result of this test.

8.26 If the Shift Supervisor wants the Safety Injection block re~initiated for the train, short terminals 2 and 6 on TDl and have the Control Operator depress S.I.
