-l STARnTP TEST REPORT (SUPPLEMENT 5)

I l

1. The River Bend Unit i Startup Test Program was officially l concluded on June- 16, 1986. This report contains an update l on the status of test exceptions which were open as of the j July 28, 1987 supplement to the Gulf States Utilities J Company, River Bend Unit 1, Startup Test Report. Since the July 28th report, no test exceptions have been closed. A total of thirteen (13) test exceptions remain open.

It is anticipated that several test exceptions will be closed out following River Bend's first refueling outage and ]

subsequent power ascension. l

2. All open test exceptions are categorized as affecting level 2 criteria or lower. Any level I criteria failures referenced in previous reports were downgraded to level 2 criteria as a resule of appropriate engineering analysis and are considered level 2 criteria in this report. This is consistent with the treatment of all test criteria referenced in the initial Startup Test Report. All open test exceptions were evaluated and cleared for continued safe, full power. opera *1cn.

3. Currently, the remaining open test exceptions are assigned to 4 the individual system engineers to which the test exceptions  ;

are applicable. It is felt that each engineers's knowledge i of the system will aid in expediting the closure of the remaining open test exceptions.

ST-1 Chemistry and Radiochemistry.

'TE 13: HEPA pre-filter efficiency did not meet level 2 acceptance criteria. Existing radionuclides levels continue to be insufficient to adequately measure filter efficiency. Data is being reviewed by CSU and it may be possible to close the TE, as is. t STATUS: Open TE 16: Insufficient radionuclides levels to determine off-gas pre- and post treatment monitor response versus release rate. This exception is to be resubmitted to the FRC for review and possible acceptance.

STATUS: Open Note: These level 2 test exceptions have been evaluated as not impacting safe, full power operation.

ST-13 Process Computer TE 12: Temperature calibration problems were discovered as a result of BOP testing. These problems are still in the process of being corrected. Testing will be completed upon corrective maintenance on RTD calibration problem.

Instrumentation and Controls calibration work is being worked as mar,ower permits. This level 2 exception was evaluated as not impacting safe, full power operation.

STATUS: Open ST-22 Pressure Regulator TE 22: Pressure regulator failed level 2 criteria for incremental regulation. No further progress has been made since the last supplement update. This exception will require retest. This exception has been determined not to impact safe, full power operation.

STATUS: Open Page 3 of 5

, i TE 19: Results. of feedwater study by~ GE nearly complete to determine required modifications- (if any) to' conduct ,

retest. Retest is required due to f16w transmitters being recalibrates. This level 2 exception was evaluated as not impacting safe, full power operation.

STATUS: Open ST-25C/D Main Steam Line Flow Instrumentation  ;

TE' 3: The elbow tap flow versus delta P curves are not within I

+5% of the design curves. The largest deviation is 32%.

Work is currently identified on the preventative maintenance schedule to be worked during the refueling outage. General Electric has evaluated this data and  !

agreed that this level 2 test exception does not- impact i safe, full power operation.

STATUS: Open ST-30C Recirculation System Performance TE 3: The Flow Control Valve mismatch that existed was reduced from 14% to'7% and the core and drive flow shortfalls have been resolved. GE and GSU evaluation is continuing on resolving the M ratio below design acceptance- for Loop B problem. Retest will be necessary to satisfy the disposition of the M ratio problem due to the reduced ,

Flow Control Valve mismatch. No further progress made f since last supplement update. This level 2 test exception does not impact safe, full power operation.  ;

STATUS: Open ST-74 Offgas System TE 14: This TE was created as a result of the level 2 failures resulting from the retest of TE 12. The data from the retest is being evaluated by GSU for disposition. This level 2 test exception does not impact safe, full power operation.

STATUS: Open Page 4 of 5

-ST-95 Emergency Response Information System TEl _3: Module SD-10 for performing scram timing failed. Work f requests for correcting the problem have been completed.

A~ scram is now required.to validate the timing. This

-level :2 exception does not . impact. sa f e', full power operation. {

I STATUS: Open i

-ST-100 Piping Vibration 1 TE 16: Vibration data for MSS Points T42 and T220 was not available due to failure of ERIS data collection panel  ;

113, . Panel 113 has been repaired. Currently verifying {

satisfactory piping vibration sensors in- the field. l This' level 2 test' exception does not impact safe, full power operation.

STATUS: Open TE 20: During generator load rejection (ST-27) points MSS T-42Z, T-235X, Y, & Z, & FWS T-144X failed level I criteria.- MSS T-42X and FWS T-144Y and Z failed level 2 criteria.. No data was available for condensate test point :T/S-525 since CNN-A0V 119 failed to open. This test exception is open pending retest. Computer points are available. ; Currently verifying satisfactory piping vibration sensors in the field. The test- data was-reviewed and all level 1 test exceptions were downgraded to level 2 by S&W/NuPE. These level 2 test exceptions do not impact' safe, full power operation.  !

STATUS: Open TE 21: Test points MSS T-200, FWS T-39, SVV T-39, and T-85 were f

~

not operable during generator load rejection. Requires repair to ERIS data collection panel 107. This work is not scheduled for the refueling outage, however, the j piping vibration sensors in the field are being checked l out. This level 2 test exception remains open for l retest and does not impact safe, full power operation.

STATUS: Open i

ST-104 ESF Area Cooling TE 2: Measured ESF room temperature in the HPCS, RCIC RHR A,  !

RHR B, RHR C, exceed level 3 criteria of 90 6F. No  ;

further progress ..~ been made since the last supplement i update. This level 3 test exception does not impact Safe, full power operation. .
