.. STARTUPTESTREPORT(SUPPLEMENT 13)

J L

L F - ,

1. The River Bend Station - Unit 1 Startup Test Program was concluded y" on June ~16, 1986. This supplemental ' report provide' s the current status of open test exceptions from the July 27, 1989 supplement of

! the Gulf States Utilities Company, River Bend Station - Unit 1, Startup Test Report. Since the July 27, 1989 report, no test exceptions have been closed and nine open test exceptions remain.

, 2. All open . test exceptions are categorized as affecting. level 2

( criteria or lower. Any level l1 criteria failures referenced in i

previous supplements were downgraded to level 2 criteria as a result F of appropriate engineering analysis and are considered level 2 e 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 approved by the on-site -

L review committee for continued, safe, full power operation of River i Bend Station Unit 1,

3. Currently, the test exceptions are assigned to the individual system engineers to which the exceptions are most applicable. It is

-believed that each ' engineer's knowledge of the system will aid in expediting the closure.of the test exceptions.

ST-13 Process Computer I L'

TE-12: Temperature calibration problems were discovered as a result of  !

B0P testing. 'These problems are still in the process of being K corrected. Testing .will be completed upon corrective t maintenance on RTD calibration problem. Instrumentation and 1 Controls calibration work is being worked as manpower permits.

This level 2 exception was evaluated as not impacting safe, full

- power operation. -

1 STATUS: Open 3

ST-22 Pressure Regulator I

.TE-22: Pressure regulator failed Level 2 criteria for incremental regulation. This exception will require retest, and a test  :

b procedure has been drafted by on-site GE personnel which will perform the retest. This exception has been determined not to impact safe, full power operation.

STATUS: Open ST-23A Water Level Setpoint, Manual Feedwater Flow Changes  ;

TE-19: Results of feedwater study by GE nearly complete to determine  !

required modifications (if any) to conduct retest. Retest is required due to flow transmitters being recalibrated. A retest procedure for this test exception has been drafted by on-site GE personnel. This level 2 exception was evaluated as not -

impacting safe, full power operation.

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

L TE-3: The elbow tap flow versus delta P curves are not within + 5% of L 'the design curves. Elbow tap flow data was taken during~ power ascension following the Refueling Outage (RF-1). Engineering is evaluating field data to determine required main steam line flow instrumentation calibration changes. A Modification Request (MR) is being processed to change applicable vendor doct. mentation.  ;

I General Electric has evaluated this data and agreed that this level 2 test exception does not impact :,afe, full power operation.

STATUS: Open Page 3 of 5

L TE-3: The Flow Control Valve mismatch that existed was reduced from 14%

I- to 7% and the core and drive flow shortfalls have been resolved.

L' 'GE and GSU evaluation is continuing on resolving the M ratio-below design acceptance for Loop B problem. Retest may be if necessary to satisfy the disposition of the M ratio problem due to the reduced Flow Control Valve mismatch. A retest procedure

-has been drafted by on-site GE personnel. This level 2 test

[ exception does not impact safe, full power operation.

STATUS: Open o

) ST-95 Emergency Response Infomation System L TE-3: Module SD-10 for performing scram timing failed. This module  ;

L only addressed the scram time of one rod. Work requests for correcting the problem were completed. However, this module L failed again during retest. Plant maintenance and engineering personnel have not yet determined the cause of the second failure This level 2 exception does not impact safe, full power operation.

STATUS: Open  ;

i i ST-100 Piping-Vibration

]

TE-16: Vibration data for MSS Points T42 and T220 were not available  !

due to failure of ERIS data collection panel 113. Panel 113 has i been repaired. Lanyard pots for MSS-T220 were refurbished and calibrated during the first refueling outage. 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, and FWS T-144X failed. Level I criteria. MSS i i

-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.

Coputer points are available. The lanyard pots for points MSS-T235, CNM-T525 and FWS-T144 were refurbished and calibrated during the first refueling outage. The test data was reviewed  !

and found acceptable for continued safe, full power operation (downgraded to level 2) by S&W/NuPE. l STATUS: Open  !
