?Startup Test Report - Supplement 12-o The River Bend Station: . Unit:1 Startup Test Program'was concluded on' June L 16,' 1986. . This ' supplemental report provides the current status of open.

test exceptions from.the April 27, .1989 supplement of .the Gulf States Utilities Company, River Bend Station - Unit-1,.Startup Test Report. Since

- the April- 27, 1989 report, one test' exception has been closed and nine open test exceptions remain All open test' exceptions are categorized as affecting level 2 criteria or lower. Any level 1 criteria failures . referenced . in previous. supplements-were downgraded to. level 2 criteria as'a result of appropriate engineering analysis and are consideredclevel-2 criteria in .this report. This- is:

consistent with the treatment of all' test' criteria referenced in the

'n

' initial Startup Test Report. All open test exceptions were evaluated and approved .by -theoon-site review committee.for continued, safe,. full power

.'i operation of River Bend Station - Unit 1.

Currently, the test exceptions are assigned -to the individual . system engineers to which the exceptions are most applicable. It.is believed.that i each engineers' knowledge of the system will aid in expediting the closure of theftest exceptions.

hT-13ProcessComputer TE 12:- Temperature calibration problems were discovered as a result of B0P t,esting. 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 manpower permits. This level 2 exception was evaluated as: not impacting sa fe , full power

' operation.

STATUS: Open ST-22 Pressure Regulator TE 22: Pressure regulator failed level 2 criteria for incremental regulation. .This exception will require retest, and a test procedure has been. drafted by on-site GE personnel which will J

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 b GE nearly complete to determine required modifications (if any) y to conduct retest. Retest is required due to flow transmitters being recalibrates. 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 TE 3: The elbow tap flow versus delta P curves are not within +5% of 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 documentation.

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

STATUS: Open Page 2 of 4

,ST-30C Recirculation. System Perfomance 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 thel 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 ST-95 Emergency Response Information System TE 3: Module SD-10 for' performing scram timing failed. Work requests

-for correcting the problem was completed. However, this module failed again during the 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 ST-100 Piping Vibration 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. . 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, & FWS T-144X. failed level I criteria. MSS T-42X and FWS T-144Y and.Z failed'1evel 2 criteria. No data was available for

. condensate test point T/S-525 since CNN-A0V 119 failed to open.

This-testtexception is open pending retest. Computer 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.  !

STATUS: Open  !

data -' collection panel 107. This work was not scheduled for the-refueling. outage, however,:the piping vibration sensors in the field were checked out. This level 2 test exception remains open-for retest and does not impact safe, full power operation.

STATUS: Open ST-104 ESF Area Cooling r

L TE 2: ' Measured ESF room temperature in the HPCS, RCIC, RHR A, RHR B, RHR C, exceed level 3 criteria of 90 degrees Fahrenheit. This level 3 test exception does'not impact safe,' full power operation. .The qualified equirment in the ESF rooms, RHR A, RHR B, RHR C, RCIC and HPCS are qualified at a minimum ambient temperature of 145 L degrees Fahrenheit. This qualified operating temperature exceeds L the requirements of S7-104, TE 2. This data has'been reviewed by the Facility Review Committee and it has been' accepted'as-is.
