6. SurveiiIance Observation Duriry the inspection period, the inspector verified plant operations cmpilance with at least sixteen different technical specification requ:re-ments. Systerns observed included refueling water tank, contairrnent spray,

,

diesel generators, reactor coolant systmlleakage, chemistry, pressure /

tmperature Iimi ts, ard other The inspector reviewed operating procedure 0120051, Rev. 6, Reactor Coolant

,

System Flow Verification by Calorimetrics, for cmpleteness, technical L accuracy, approval, etc. Final flow calculation was found to agree with the

, previous detennination wi thin 0.5%. The inspector verified that testiry was performed in accordance with adequate procedures, test instrtmentation was calibrated, limi ting condi tions for operation were rnet, rmuval and restora-tion of the af fected cmponents were properly accmplished, test results met requirarents and were reviewed by personnel other than the individual directing the test, and that any deficiencies identified during the testiry were properly reviewed and resolved by appropriate nunagenent personnel .

No violations or deviations were identifled in this are . Maintenance Observation Station rmintenance activities of safety-related systmis and conponents

,

listed below were observed / reviewed to ascertain that they were conducted in accordance wi th requirmients. The foilowing itans were considered during this review: the limiting conditions for operation were met; activi ties were accmplished using approved procedures; functional testing and/or calibrations were performed prior to returning conponents or systems to service; quality control records h were nuintained; activities were accmpiished by qua1ified personnei; j' parts and nuterials used were properly certified; and radiological controls were inplemented as required. Work requests were reviewed to detennine status of outstanding jobs and to assure that priority is '

j assigned to safety-related equipnent rmintenance which nuy af fect r systun perfonmnce. The foilowing nuintenance activities were

!

observed / reviewed:

On Tuesday, April 20, 1982 the inspector reviewed Plant Work Order No. 7054, which performed work on Pressure hidicator 2208. A gage that senses pressure on the "B" boric acid punp discharge. The sensing iine was pitgged and the gage indicated no pressure. A heat

,, imp was placed on the sensing iine for one hour and then the 1A and l 1B boric acid pmps were run to verify unplugging of the sensing lin Discussions with plant ILC personnel indicate this to be a continuing

.

probl an. The nuin piping is heat traced up to an isolation diaphragm,

! but the capillary tube from the diaphragn to the gage is exposed and j not heat traced.

Confirming indications included stnp level and contalrnent particulate alanns at the alert and high Icvels. The operators conducted a contairment entry and found a leak blowiry steam at the location of the pressurizer cubicle. The clouds of steam stopped when spray control valve 1100F was isolated locally. A leak rate calculation confirmed the stopping of the leak. W e licensee stated-the intention to investigate the problem during an upcoming scheduled outage.

There were no injuries, no penmnent danuge, no release of radiactive nuterials, and no exposure of personnel. All involved were given whole body count No violations or deviations were identified during this even . Hydrostatic Test Procedures - Unit 2 During this inspection period the inspector reviaved SQP-14 Revision Integri ty Testing; Quality Instruction QI 10.78, Revision 1 - Integrity Testing Inspection and interviewed supervising personnel in this are It was ascertained that SQP-14 did not specify that connected piping and equiptent adjacent to but outside hydrostatic test boundaries nust be protected frcm overpressurization. SQP-14 did not require any doctmentation of this protection. QI 10.78 did not require any inspection of such protectio At the request of the inspector, Construction Test nom CT-027-82 was issued to clari fy SQP 14. The applicant has cmmitted to establish a program to evaluate the sone 1200 previous Hydrostatic Tests to demonstrate there was no danuge to adjacent portions of systens.
