GULF STATES UTILITIES COMPANY RIVER BEND STATION UNIT 1 STARTUP TEST REPORT (SUPPLEMENT 1) 30 OCTOBER 1986 8612040109Og000SB PDR ADOCK PDR P
.. . s STARTUP TEST REPORT (SUPPLEMENT 1)
- 1. The River Bend Unit 1 Startup Test Program officially was concluded on June 16, 1986. This Report contains an update on the status of the test exceptions which were open as of 15 July 1986 when the Gulf States Utilities Company River Bend Unit 1 Startup Test Report was written. Since 15 July 1986 forty-two (42) test exceptions have been closed, two (2) have been created as a result of retests and eighteen (18) remain open.
- 2. All open test exceptions are categorized as affecting level 2 criteria or lower. Any Level 1 criteria failures referenced in the report were promptly downgraded to Level 2 criteria as a result of appropriate engineering analysis and are considered Level 2 criteria in this report. This is consistent with the treatement of all test criteria referenced in the initial Startup Test Report. All open test exceptions were evaluated and cleared for continued full power operation.

' s ST-1 CHEMISTRY AND RADIOCHEMISTRY
))! DESCRIPTION STATUS 13 HEPA pre-filter efficiency did not meet OPEN level 2 acceptance criteria. Existing radionuclides levels are insufficient to adequately measure filter efficiency.
A retest will be performed when radio-nuclides levels are higher.
16 Insufficient Radionuclides levels to de- OPEN termine off gas Pre and Post treatment monitor response versus release rate.
Repeat when off-gas activities are sufficient to establish trending. This test exception affects level 2 criteria.
These two (2) Level 2 test exceptions (TE-13 and TE-16) were evaluated as not impacting safe, full power operation.
ST-11 LPRM CALIBRATION TE DESCRIPTION STATUS 8 LPRM's 6B-38-15 and 2D-38-47 are in- CLOSED' operable and therefore were not calibrated. Repair and retest is part of Maintenance Work Request (MWR) 38043 and 38049. There is no test criteria associated with this test exception.
ST-13 PROCESS COMPUTER TE DESCRIPTION STATUS 4 Spacer /LPRM dips are not distinguishable CLOSED at low power level. Retest is now completed.
12 BOP calculations were not verified due to OPEN late software delivery. Calculations are 90% verified. Temperature calibration pro-blems were discovered as a result of BOP testing and are in the process of being corrected. Verification will be completed upon corrective maintenance on RTD calibra-tion problem. This Level 2 exception was evaluated as not impacting safe full power operation.

ST-23D MAXIMUM FEEDWATER RUNOUT CAPABILITY TE DESCRIPTION STATUS 3 Level 2 criteria was exceeded in the 3 CLOSED pump /3 valve configuration when CNM-AOV119 failed to open. General Electric Engineer-ing has determined that the test results were acceptable.
ST-24 TURBINE VALVE SURVEILLANCE TE DESCRIPTION STATUS 3 Turbine valve surveillance at high power CLOSED level was not performed due to inoperable moisture separator / reheater. Since River Bend currently does not intend to per-form TCV surveillance testing above 85%
power this test exception has been closed.
ST-25C/D MAIN STEAM LINE FLOW INSTRUMENTATION TE DESCRIPTION STATUS 3 The elbow tap flow versus delta P curves OPEN are not within + 5% of the design curves.
The largest deviation is 32%. General Electric has evaluated this data and agreed that this exception does not impact full power operation. Investigation is continu-ing however, to determine the cause.
5 The flow venturi delta P as extrapo- CLOSED lated to 140% rated steam flow is 157 psid versus level 2 criteria of 178 psid.
Design documents have been changed and the Technical Specification has been approved by the FRC.

- s ST-29 RECIRCULATION FLOW CONTROL TE DESCRIPTION STATUS 4 Flux Loop and Flux Estimator testing was CLOSED not conducted in order to expedite testing.
Since this mode of operation will not be used, Flux Loop testing has been deleted.
10 The duty cycles for FCV "A" and "B" did CLOSED not satisfy the level 2 criteria of 0.2% Hz.
A retest is needed. This Test Exception was closed since it is a duplicate of TE-18.
17 Flux Loop and Flux Estimator testing was CLOSED not performed since this feature will not be utilized at River Bend. Flux Loop testing has been deleted (See ST-29 TE-4).
18 Duty cycle testing was not performed based OPEN on failure at similar test conditions at TC-3 (See TE-10). Based on General Electric San Jose recommendations position indicators were recalibrated and retest to be performed.
This exception was evaluated to have no im-pact on full power operation.
ST-30C RECIRCULATION SYSTEM PERFORMANCE TE DESCRIPTION STATUS 3 Flow control valve mismatch exists. Core OPEN flow and drive flow shortfall exist when considering individual flow control valve positions though total loop and core flows are satisfactory. This TE is under evaluation by General Electric Engineering.
This TE affects level 2 criteria. This ex-ception was evaluated to have no impact on full power operation.

TE DESCRIPTION STATUS 20 During generator load rejection (ST-27) OPEN points MSS T-42Z, T-235 X, Y, & Z, FWS T-144X, failed Level l criteria. MSS T-42X and FWS T-144Y and Z failed Level 2 criteria. No data was available for conden-sate test point T/S-525 since AOV-119 failed to open. The test data was reviewed and found acceptable for continued power operation (downgraded to Level 2) by S&W/NuPE. This TE is open pending retest.
21 Test points MSS T-220, FWS T-39, SVV T-39 OPEN and T-85 were not operable during genera-tor load rejection. Open for retest.
ST-100, TE-15, 16, 19, 20 and 21 require that ERIS Panel 107 be operable. Failure of the panel resulted in the inability to collect data. The panel will be repaired and retesting performed. Engineering analysis was performed on these test exceptions utilizing actual vibration / expansion measurements recorded at previous test conditions and existing stress analysis, where appropriate. The engineers concluded that all Level I criteria violations could be downgraded to Level 2 and these open exceptions did not impact continued operation at full power.

}]
29 Rated Feedwater expansion data, per TE-20, CLOSED was unsatisfactory for test points E-35, E-50 and E-941 due to a inoperable ERIS drywell panel. ERIS panel was repaired and test points were retested.
37 During retest of Reactor Water Cleanup per OPEN TE-21, WCS test point E-56X failed Level 1 and WCS snubber PSSP-3013-Al failed Level 2 criteria. Retest is required.
