Page 1 Background

A routine safety inspection

was conducted by Messrs.James A.Isom, David J.Hartland, and Douglas L.Shepard from Jurie 4, 1994, through July 1, 1994.During this inspection, one item was found to be in violation.

The violation was identified

as the failure to correct che root cause for the repeated packing failures of a Unit 2 main steam test selector valve over a period of two years that resulted in several entries into four-hour limiting conditions

of operation.

This violation was set forth in a letter containing

the notice of violation, dated July 20, 1994, fromMr.E.G.Greenman, Director, Division of Reactor Projects, USNRC, Region III.The letter was received July 25, 1994.Our response to the notice of violation is contained within this document.NRC Violation"10 CFR 50, Appendix B, Criterion XVI,"Corrective

Action," requires in part that"Measures shall be established

to assure that conditions

adverse to quality are promptly identified

and corrected.

In the case of significant

conditions

adverse to quality, the measures shall assure that the cause of the condition is determined

and corrective

action taken to preclude repetition." Contrary to the above, as of July 1, 1994, the licensee failed to replace the pitted valve stem on main steam stop valve (MSSV)dump valve test selector, 2-MM0-240, a significant

condition adverse to quality.Specifically, Action Request 25594 had been written on July 8,'992, to replace the pitted valve stem but was not scheduled to be performed until the refueling outage starting in September 1994.Consequently, 2-MMO-240 had to be repacked five times, requiring entries into the four hour Limiting Condition of Operation (LCO), as required by Technical Specification (TS)4.7.1.5.1.

There were several opportunities

since July 1992 to replace the stem without entering the LCO.This is a Severity Level IV violation (Supplement

I).

TO AEP:NRC: 1212G Page 2 Response to Violation dmissio or Denial o the Alle ed Violat o Indiana Michigan Power Company admits to the violation as cited in the NRC notice of violation.

2.easons for the Violatio The root cause for this violation has been identified

as a programmatic

weakness in the plant's corrective

action program.In July 1992, Unit 2 was in Mode 3 (Hot Standby).While repacking 2-MM0-240, the valve stem was found to be pitted, scored and in need of replacement.

At that time an Action Request was initiated to replace the stem.Since a repair activity of this type requires cooldown to Mode 5 to perform, a scheduling

code of U2R94 was assigned, adding the repair to the scope of the 1994 refueling outage.At the time the U2R94 code was assigned, in the absence of prior failure history, this was the correct designation.

The valve stem replacement

would only have been elevated to the forced outage schedule if the subsequent, repeated repairs had been identified

as rework and an adverse trend.Since the valve stem deficiency

was first identified, 2-MMO-240 has been repacked five additional

times.Had the valve stem replacement

been scheduled as a forced outage activity, there would have been two opportunities

prior to the violation to complete the repair.The first opportunity

occurred in August 1993 when the unit experienced

a reactor trip and forced outage.The second opportunity

occurred in January 1994 when the unit was removed from service to repair an unisolable

steam leak on Steam Generator 21 blowdown line.Repeated packing replacements

were not identified

in the plant's Corrective

Action Program (PMI-7030)

as an adverse trend.PMI-7030,"Corrective

Action Program," requires a condition report to be written for similar corrective

maintenance

work within 90 days of the original deficiency.

Only the final packing failure on May 17, 1994, fell within the 90 day criteria, as this failure occurred 57 days after the previous repair on March 21, 1994.

ATTACHMENT

TO AEP:NRC: 12120 Page 3 A rework condition report was not initiated following the May 17 failure due to an error in the Maintenance

Administrative

Procedure (MAP)¹MA3.3-05,"Maintenance

Planning".

MAP¹MA3.3-05 incorrectly

defined rework as similar work performed within 30 days of the original failure, rather than 90 days.As a result of this error the maintenance

planner failed to identify the reoccurrence

of the packing leak on May 17, 1994, as falling within the definition

of rework.3.Cor ective Actions Taken and esults eyed The work control process code was changed on the 2-MMO-240 repair Job Order.The 2-MMO-240 repair task now appears on the forced outage schedule, as well as within the scope of the refueling outage.MAP¹MA3.3-05,"Maintenance

Planning," was revised to reflect the current definition

of rework contained in PMI-7030.4.Corrective

Actions Taken to Avoid Further Violations

PMI-7030,"Corrective

Action," will be revised to redefine rework.The definition

for rework will now include any corrective

maintenance

which requires entry into a Limiting Condition of Operation (LCO)if similar work has been performed on that equipment/component

during the current operating cycle, including the previous refueling outage.When rework of this type occurs, a Condition Report will be written to aid in the identification/evaluation

of an adverse trend.The"90-day" standard will be retained for work upon equipment or components

which do not initiate an LCO entry.MAP¹MA3.3-05,"Maintenance

Planning," will be revised to refer to PMI-7030 for the above-described

redefinition

of rework.These measures will assure that this type of condition will be precluded in the future.5.ate When Full Com lienee Will Be Achieved PMI-7030 and MAP modifications

will be completed by September 30, 1994.

for 2-MMO-240 will be completed during the first Mode 5 forced outage of sufficient

duration or the upcoming Unit 2 refueling outage, scheduled to commence September 6, 1994, whichever occurs first.
