• Use of acceptance criteria to evaluate test results

Verification that plant supporting systems are in service

In-service status of calibrated special test equipment required by the test procedure

Adherence to the test requirements of the test procedure during the testc

• Timely and correct action by test personnel during the performance of the tests

Data collection for final analysis by test personnel The run-in test of D/G-C was performed in accordance with test instructions orovided by the vendo Inese same instructions were also used for the run in test of D/G-A (See Inspection Report 50-353/88-17).

The following run-in schedule was used in terms of percent load versus time period:

Hours  % Load 1 25 1 3 .5 3 7 .5 3 100 The inspector made independent readings from the local panel instrument Pyrometur readings showed a maximum temperature differential of 200'F versus a max allowable of 300' The pressure dif ferential on the lube oil strainer did not exceed the allowable 10 psid. The actus1 max, pressure differential was 5 psi Problems had been experienced prior to this test with the thermostatic bypass valve of the Jacket water system. This control valve contad-power pill which controls valve notion. It contro11ea the jacke4 a at too low a temperature (144*F which is well belew the optimum cor.or '

range of 155-160*F). Temporary (non-qualified) replacement power pills had been installed to permit test continuatio The new power pill was controlling the jacket water at slightly below the optimum range, at 154 A non-conformance report (224A-618/5-30M) was issued to address the proble ,

There was a test exception for the crankcase vacuum which was too low (.3 inches of water). The desired range is .4 to 2.5 inches of wate The orifice which controls this vacuum will be modified to prov*de 1 inches of water of vacuu The test was successfully concluded following the run-in schedule ;hown above. No unacceptable conditions were noted during this test. The inspector witnessed selected steps of preoperational test procedure 2P23.1 for the Diesel Generator Fuel Oil System, Startup Subsystem 23 Problems were experienced with Level Alarm Switches LISHL 20-220A-D for the high and low level alarms of the diesel fuel oil storage tanks. The switches are designed for tanks of 30 feet height or below. The actual height of the storage tanks is about 3 feet. Control action therefore is taking place over a very small angle on the circular cam (about 7'). Four test exceptions were issued against the high and low level alarm steps of the procedure during the witnessing period. Recalibration of these level alarm switches is planned by the licensee. The inspector will follow all of these test exceptions during future NRC inspections. Apart from the level alarm switch problems, no unacceptable conditions were note . QA/QC Interface (35301)

The QA Audits and Surveillances listed in Attachment A were reviewed to ascertain the continued QA/QC involvement with the preoperational test progra With reference to the finding in audit 25-96, as reported in inspection report 50-353/88-17, concerning the timely provision of the input for the PM Data Base prior to system turnover, the licensee had taken the follow-up action to address the inspector's concer The decision for the Project Startup Engineer, not to sign the turnover document unless the input for the PM Data Base had been sent to the Startup PM Coordinator, has been incorporated in Startup Adninistrative procedure A06.1, "System / Component Turnover to PECo."

In Surveillance Check Repert 25-041, a water spill incident was investig:ted. Water ' "" 4000 gals) was accidentally dumped from the RHR System via the di... supply to the .aain steam MSRV into the Unit 2 Orywell . As part m '" rrective action taken, PECo Startup advised personnel that in the (w .;e they are to open tell-tale valve (s) outside the test boundary to ascertain any through laakag The inspector enquired whether the licensee plans to incorporate opening of the tell tale valves as a precaution in the portinent test procedure (s).

Startup management agreed to review this matter for feasibility. The inspector will follow the resolution of the above action during future NRC inspection _ _ _ _ _ _ - - .

In Finding Report 25-157 (Audit Report 25-090) it was found That Blue Tag Testing had not been performed to the latest revision of drawing M71-48(2),i.e.20BR. In addition, drawing M71-48-24BR was used without amendments when amendment FMC-M-2031 was activ Both documents were current at the time of the start of the tes It was determined that this oversight did not affect the test. The correctics action was to provide additianal training to field engineers and startup perscnnel to identify the latest design document revision, including outstanding change docu-ments, via "system 38" (Network Computer Program). The inspector enquired whether the licensee plans to revise applicable administrative procedures to require that the drawing revisions be checked for latest status prior to the test and that the effects of drawing changes be reviewed for their impact on the test procedure and the validity of the test data obtained from the test. Startup management agreed to review this matte Independent Effort A review was made of the calibration records for the indicating instruments, listti in Attachment B for Standby Diesel Generator C local panel F It was found that the use of calibration stickers for instruments on local and controi room panels was discontinued in early 1988 as a result of an INPO recommandation to PEco. Calibration records, however, are being >

maintained. A calibration sheet was found for all of the instrumerts listed in Attachment i i It was noted that th) calibration frequency was not shown on the i

individual calibration sheets. This inforr ation, however, is provided in the CHAMPS preventive mainterance computer output. The calibration frequency of all of the instrumente listed in Attachment B was 'ound to be 3 years (every othe ' refueling outage). It was concluded that all of the instruments of Attachment B had a valid calibratio The inspector also reviewed evidence on the timely transmittal of the

Preventive Maintenance (PM) Date Base information prior to system turn over. The inspector verified that the fo11 ewing transmittals were ,

accomplitned prior to the turnover date, t Speedletter to G. Feenstra, S/U Supervisor, from D. Kelsey, PM Coordinator, on S/U System 28E, 0/G Enclosure HVAC System, dated 5-11-88.

• Unit 1 PM Baseline Data marked up for Unit 2

• Unit 1 Lube List marked up for Unit 2 5. Plant Tours The inspector made several tours of the plant including the Reactor Enclosures to observe the status of construction, work in progress, housekeeping, testing activities and cleanlines No unacceptable conditions were note . Exit Interview At the conclusion of the site inspection, on August 12, 1988 an exit interview was conducted with the licensee's senior sitc representatives (denoted in Section 1). The findings were identified and previous inspection items were discusse At no time during this inspection was written material provided to the licensee by the inspector. Based on the NRC Region I review of this report and discussions held with licensee representatives during this inspection, it was determined that this report does not contain information subject to 10 CFR 2.790 restrictions.
