Subj ect: Response to Inspection Report (IR) 50-346/890015 (Unresolved Item l
89015-01)
Gentlemen:
Nuclear Regulatory Commission (NRC) letter dated' June 23,.1989 (Log Number
]
1-2115) requested Toledo Edison (TE) to respond to NRC concerns that TE's Request for Assistance (RFA)/ Document Change Request-(DCR) process does not provide a program for determining design document deficiency trending and for performing root cause analyses and additional reviews of similat areas if trending identified a pervasive problem. The letter requested TE to provide a discussion of how TE's current program determines design document deficiency trending, and when pervasive problems arc;found to' exist, how root cause l
enalyses and additional reviews and actions are performed to assure adequate resolution.
j During the exit meeting for IR 50-346/89015, TE acknowledged that no ongoing program existed for root cause and trending of DCR's and agreed to evaluate the inspector's concern and to consider implementing such a program.
Toledo Edison's evaluation included a review of the DCR process and the. Configuration Management Program (CMP). The CMP identified document discrepancies during-
- i extensive walkdowns that were conducted under this program. These discrepancies are presently being evaluated under a comprehensive on-going effort in which personnel recognize trends during the disposition of these l
discrepancies. The CMP included provisions for-performing root.cause analysis and taking corrective action to prevent recurrence.- Other design document discrepancies are being identified and resolved through the RFA/DCR process separate from the CMP. The current RFA/DCR process for evaluating and' correcting design document deficiencies does not include such provisions.
