SUBJECT:

INSERVICE TESTING PROGRAM FOR PUMPS AND VALVES, ST.

LUCIE PLANT, UNIT NO.

1 As a result of.our review of your inservice testing program for pumps and valves, including a staff visit to the site, the staff has determined that additional information is required to complete its review.

The specific requests are identified in the enclosure to this letter.

It is requested that you provide the information by May 18, 1984 or advise us of the date you can provide the information within 10 days of receipt of this letter.

A copy of your response should be sent to NRC's Region II marked for the attention of W. Ross.

If you have any questions, please contact the project manager, D. Sells at (301) 492-9735.

The reporting and/or recordkeeping requirements contained in this letter affect fewer than ten respondents; therefore, OMB clearance is not required under P.L.96-511.

Sincerely, Origine) signed by o.~. ~~

N 1.

The following valves at St.

Lucie Unit 1

are not included in your IST program.

Please justify why these valves were omitted or else submit a

revision of your program that includes these valves and any additional reauests for relief from the AStlE Code that are appropriate.

Chemical Volume and Control System valves SE-02-03, SE-02-04, V-2324, V-2325, V-2326, V-2315, V-2318, V-2321, V-2435, V-2105, V-2199, V-2118, V-2526, V-03920, and the heat traced piping thermal reliefs.

Safety Injection System valves V-3211, V-3221, V-3231, V-3241, V-3439, V-3637, V-3647, V-3439, V-3468, V-3483, V-3469, V-3482, V-3430, V-3431, V-3407, V-3417 and V-03920 Containment Spray System valves V-07256 and V-07258 2.

The following check valves are categorized as C valves in your program.

These valves perform a 'pressure isolation function between the high pressure Reactor Coolant System and the lower pressure Safety Injection System.

Consequently, maximum leakage limits for these valves are specified by the St.

Lucie Unit 1 Technical Specifications.

please justify why these valves should not be categorized and tested as AC valves or submit a revision to your program that reflects an AC categorization.

Safety Injection System valves V-3113, V-3114, V-3123, V-3124, V-3133, V-3134, V-3143, V-3144, V-3217, V-3227, V-3237 and V-3247 3.

The staff has identified the follow'ina eight valves as also performing pressure isolation functions.

please justify why these valves should not have leak test-'equirements such as those in Technical Specification 3.4.6.2 or else revise the St. Lucie Unit 1

IST program accordingly.

Valves V-3215, V-3225, V-3235, V-3245, V-3480, V-3481, V-3651 and V-3652 4.

During the staff's review of the St. Lucie IST program, we were advised that the program was being revised to propose testing the following valves during cold shutdown and other revisions would also be submitted for these CVCS valves.

Valves SE-02-01, SE-02-02, V-2515, V-2516, V-2501 and V-2504 Please document these revisions.

During the staff's

review, we were advised that additional time was needed to provide justification that valves V-2177 and V-2190 cannot be flow tested during refueling outages.

Please provide this justification or commit to a

flow test.

6.

You have requested relief from requirements of paragraph IWV-3520 of Section XI of the ASME Code for valves V-3215, 3225,

3235, and 3245 (Safety Injection Tank discharge check valves) and propose to part-stroke exercise these valves during refueling outages.

This proposed

test, alone, is unacceptable;

however, the staff will approve your proposal if you commit to further verify operability of these valves by disassembling and manually stroking these valves at 10 year or less intervals.

Please provide this commitment or justify the basis for a non-commitment.

7.

Justify why valves V-3463 and I-V07009 (discharge from SIT to RWST) should not be categorized as AE and be given the operational checks required by Paragraph IWV-3700.

8.

You have requested rel ief from Paragraph IWV-3410 for valves FSE-27-1 through FSE-27-11 (Hydrogen Sampling) and valves I-SE-17-1A and I-SE-17-18 (Diesel Oil) and propose alternative methods of verifying operability of these valves.

We recognize the difficulties involved in stroke-timing solenoid valves; however your proposals address only one limiting value; i.e., verifying valve opening and closure.

It is our position that stroke timing also provides information relative to valve degradation.

Con-sequently, we believe that you should seek methods to establish stroke timing through such techniques as fail-safe closure or a

coarse stroke time (2 second maximum).

Please provide a commitment to investigate further more exact stroke timing methods.
