REPLY TO NOTICE OF VIOLATION 50 4S8/9305-01 LEVEL IV AM'CE Notice of Violadon - I.ctter fmm A.B. Beach to P.D. Graham dated April 30,1993.

VIOLATION 10 CFR Part 50, Appendix B, Criterion XI, " Test Control," states, in part, that a test program shall be established to assure that all testmg required to demonstrate that stmetures, systems and components will perform satisfactorily in service is identified and performed in accordance with written test pmcedures which incorporate the requirements and acceptance limits contained in applicable design documents.

Contrary to the above, on February 24,1993, all testing required to demonstrate that Control

,

Building Instrument Air Solenoid Operated Valve 11AS'SOV36A would perform satisfactorily

'

was not idettfied and performed, in that maintenance that could have affected seat and bonnet leakage integrrty was performed, and the post maintenance test did not verify that the leakage

,

inw.yky of the valve was adequate.

In addition, the maintmance pufwwcd included diuuembly and adjustment of the valve position indicating reed switches, but the post-mamtenance test did not verify the appropriate position indimtion which caused the stroke time test to be invalid.

MASON FOR THE VIOLATION When a maintenance work order (MWO)is generated for a condition /ptoblem, the maintenance planner incorporates all the applicable docutnents and procedures into the work package as addressed by his program. Involved in this process is the post maintenance test (PMT)

requirements which are the specific test procedures performext as required by Operations, Maintenance, System Engineering, motor operated valve (MOV), in-service test (IST), and local leak rate tea (LLRT) groups. When the planner is completed with the package, he routes the MWO to the applicable departments for their review. The department's review involves review of their specific sections of the MWO for accuracy, review of the e=tre package for completeness, and determination of proper retest requirements. In this instance, not all the appropriate retests wqe specified in the MWO package nor were the retests identified in the subsequent review.

In this case, the specific package for valve IAS*SOV36A was generated due to the solenoid valve (SOV) failing its stroke time test. The package detailed the removal and dimwmbly of the valve to troubleshoot and reparr. In the package, the directions provided a clear order of steps to accomplish the repair. It also indicated that the reed switch assembly was to be matched prior to removal, and returned to its original position upon reassembly.

Based on this information, the engineer reviewed the package and determmed that the stroke time surveillance test (STP-122-6301) was a sufficient test to fulfill the PMT requirements.

Incal position indistion verification was determined to not be necessary because the specified steps regarding dia"embly of the valve per the MWO, vendor manual, and work practices were deemed adequate by System Engmeering.

A leak test was not specified by the System 1 OF 2

Engineering IST CocidL L henne IAS*SOV36A is o Category "B' valve per ASME XI and

as such does not require testing for seat leakage. Other leakage test requirements were not

COnnreTIVE sim.r5 TAKEN AND RRWLTS ACHIEVED Condition Reort #93-0093 was generated to address the concerns on the post mairnenance test regul.

i I.eekage through IIAS*SOV36A has been measured as part of the total accumulator leak test in l

TSP-0029 "Contml Building Air Accumulator Test." R==a performance of this test requires

rendering both divisions of Control Room HVAC inoperable, 'ISP-0029 is scheduled during

refuelings only. Per the disposition of CR 93-0093, the local position verification section of STP-122-6301 was performed as an equivalent retest to dhmine if there was gmss leakage

,

through IIAS'SOV36A. The valve exhibited no lenkage in this test.

,

11AS*SOV36A is backed up by a check valve so that there is radandant protection against excessive leshge. The citenla+ian for the control building air amunulators includes leakage i

for the SOV and the check valve. This calculation provides enough margin to conclude that if no gross leakage exists through the SOV, then the systcm r,;ill refonu lis.wfoty fuusica should the need arise,

,

COnnwrTIVE sTa.r5 WHICH WTTL BE TAKEN TO AVOID FURTHER FINDINGS A review of other plant procedures including technical section procedures (TSPs) will be performed to identify any procedures which contain tests that may be required after maintenance.

'

Any tests that are identified through this review will be added to the Maintenance Plannmg

Guidatinam as required post maintenance tests for applicable components. The Maintenance Plannmg Guidelines will be revised as required. In addition, the test method used to determine

leshge through IIAS*SOV36A per the local position verification section of STP-122-6301 will i

be used in the future following maintenance on both IIAS*SOV36A and IIAS'SOV36B. The

]

section will be identified in the STP as being a post a.intenance test requirement.

DATE WHEN FUIL COMPr IANCE WTIL BE ACHTEVED

-

The initial Itnnew of techniemi section procedures has been completed. There were no other

!

cases mirnilar to TSP-CiO29 identified in this portion of the review. Further review of other plant proceditres and any naca*=3 revision to the Maintenance Planning Guidelines will be completed by October 31,1993.
