STUP: 86-736 i

Dear Mr. Hickman:

MO At D. Smith's request I am sending you excerpts from the pressurizer control test done during Hot Functional testing. In the packet are:

1. The applicable pages of the test (pp 30 through 32)

2. A Package consisting of the: '

a. The test Review Board Minutes (May 20, 1986)-

b. The Joint Test Review Meeting Minutes (June 16, 1986)

c. An addendum to the above (June 20, 1986)

d. A Post Joint Test Review Meeting Minutes

3. The final test evaluation (Section 12, pp 1 through 20)

4. Tnso attachments to that evaluation, A & C. ,

Engineering has not accepted the analysis without re-confirming the spray valve set points. This confirmation is the basis of our request for deferral of the Pressurizer test approval.

If you have any questions concerning this material, please contact me, at 815-458-2801, ext. 2371.

Test Change Record, comment by N. Hottel: The steps recorded for TCE I as 5.2.1 through 5.2.7 are in error, step 5.2.4,5,6 are not included.

/ $ection 6.4, comment by R. Riessen: Steps 6.4.1,2,3 were not signed off prior to section 9.1 being entered on 3/27/86. This comment also applies to step 7.4.2. This has no impact on the test.

No Resolution Required.

Step 4.2 and 4.4, casament by TRE: TRB is not able to evaluate the acceptance criteria values that are listed as " nominal" in these steps. The nominal values described in 4.2 and 4.3 were at the request of Project Engineering and do not conform to the startup Manual since they do ret have a set point and a prescribed expected range.

Acceptability of the nominal values recorded in the test for these acceptance criteria will have to be further evaluated by PRD.

f Step 9.4.14, comment by R. Riessen: The deficiency written against the pressurizer level control are in,this step. Deficiency I was closed out based on the statement that it was tested in section 9.6 of nWPT-CV-11.

This does not appear to be an adequate reason for closing

. out the deficiency, when the deficient condition existed in this test.

If the controller were not tested in the same configuration in CV-11 sind under the same circumstances that the test conducted in RY-11, it appears this step in RY-17 may have to be retested.

O< , comment by M. Hottel: This deficiency was written against 9.5.25 because the high temperature annunciator in this step did not come in. This was not a deficient condition in reality since the annunciator was suppose to ccme in at a higher temperature. The STE should have a TCE to bypass the verification for the annunicator coming in.

9. Deficiency RY-17H, comment by N. Hottel: This deficiency was written against 9.3.32 because backup heaters did not de-energize, however, step 9.3.32 is signed off which indicates that the heaters did de-energize. This step should not have been signed off. This is a ,

deficient condition, however, the deficiency is closed out. The explanation indicates that the level setpoint was not reached. The TCR should have been weitten to delete that portion of the step if it was not within the setpoint range.

1. Address stop S.5.12, its test / retest chronology in the Engineering Evaluation.

2. Correct typos on page 5 and page 6 of the Engineering Evaluation. ,

3. Data collected in section S.3 concerning 1PT-455A Pressure control loop is not explicit, and therefore does NOT prove what it set out to prove. It is agreed that either additional information will be provided Cie.

pressure / time strip charts from the control board from the time of the test), or that ratesting will be performed.

a. Loop 1PT4E5A needs complete calibration, and data on each component and its out of cal tolerence must be provided.

b. If it is determined that additional data as in #3 above CANNOT be supplied, an AIR to ratest S.3 will i

be provided.

c. The test engineers who ran the test state that the Engineering Evaluation as written to explain section S.3 is INCORRECT. It must be rewritten to reflect reality. ,

SUBJECT:

BwPT-RY-17 Post Joint Test Review Meeting, Resolution of Comments I.

Resolution to J. E. Boardman letter dated 16 June 86:

1. Test / retest chronology for step 9.5.12 has been addressed

'in the engineering evaluation.

4

2. Typo's on page 5 & 6 are corrected (Engineering Evaluation) 3a. Loop 1PT-455 functions per design (as explained in the updated Engineering Evaluation, section 12.2.3). A post

' test calibration was performed during the week of 5-12-86. The post test cal consisted of inputting a signal at the sensor (i.e. pressure at IPT45J) and then verifying the indication at the points where data was collected. Results showed the pressure transmitters 1PT-455 & 456 were out of tolerance. Loop power supplies, isolators and indicators were within spec. The transmitters have been recalibrated and the out of tolerance condition addressed in section 12.2.3 of the l engineering evaluation. This is in accordance with the Braidwood Startup Manual. Therefore, a complete re-calibration is not requited.

3b. Strip charts and additional data has been provided (section 12.2.3), therefore, an AIR to retest section 9.3 is not required.

3c. The Engineering Evaluation for section 9.3 has been rewritten.

i

4. The PORV valves 1PCV-455A & 456 have been lapped. An AIR has been written to insure retest of these valves with respect to leakage.

II. Boardman letter dated 20 June 86

1. An AIR has been issued to retest PORV 455A after perminate turbine has been installed. The valve will be " hot stroked" in less than 2 seconds (open).

t III. Westinghouse Ccwents

1. Westinghouse concerns have been addressed in the updated l version of Engineering Evaluation section 12.2.3.

Westinghouse (SET) now concurs that the Master pressure Controller responds such that the Spray Valves should preclude tht opening of PORV 455 during step load decreases between 10-50*4 power.

IV. TRB Coment incorporation All TRB coments from the meeting held on May 20, 1986 have c been addressed. No further action required.
