RESPONSE TO IE INSPECTION REPORT 86-023 REVISION 2 On December 23, 1986, Consumers Power Company submitted a revised response to the violation contained in IE Inspection Report 86-023 for the Palisades Plant.
In that response, Consumers Power Company cosunitted to detail the results of an evaluation of our preplanning process.
In accordance with the commitment, Consumers Power Company is submitting this revised response detailing the results and necessary corrective actions to be taken. Revisions are indicated by lines in the right hand margin.

Administrative Procedure 5.01, " Processing Work Requests / Work Orders". A, Block 46 through 50, requires that maintenance which can affect the performance of Q-listed equipment, structures, or systems must be properly preplanned and performed in accordance with written procedures, instructions or drawings appropriate to the circumstances.
Contrary to the above, written procedures and instructions were not properly preplanned for the following maintenance activities to ensure adequate controls appropriate to the maintenance circumstances:
- 1) on August 15, 1986, Q-listed Work Order No 24606289, controlling the maintennnce activity for relocating auxiliary fuses in a station power breaker, was inadequato such that links that were opened were not reclosed.
- 2) On August 23, 1986, Switching and Tagging Order No 86-1414 was inadequate to cut out one of the IC bus undervoltage relays prior to a Q-listed maintenance activity, similar to the above, commencing.
- 3) On August 27, 1986, Q-listed Work Order No 24606631, controlling the l
installation of a turbine thrust bearing trip device, was inadequate df OC0287-0213-NLO4 8702110017 970206 l

Palisades Plant Response to IEIR 86-032 Revision 2 February 6, 1987 since it failed to state the opening and reclosing of the link that defeats the automatic diesel generators start.
Response
Corrective Actions Taken and Results Achieved Administrative procedures have been revised to provide enhanced controls during the maintenance process. Documentation of the following items is now required, when applicables slide links opened / closed, leads lifted /
landed, blank flanges installed / replaced, apool pieces removed / installed and temporary hoses installed / removed. Any individual who signs for the completion of an activity assumes the responsibility for assuring, through personnel observations, that the activity has been completed as intended.
Additionally, safety injection system and diesel generator initiation signals have been blocked and are being administrative 1y controlled during maintenance and testing. Plant personnel have also been trained and counseled so as to better recognize potential actions which could cause safety system actuations. Work orders concerning safety related bus relaying which may affect safety system actuation are presently receiving a second level review by the Electrical Department.
Corrective Actions to be Taken to Avoid Further Violations An extensive review of plant safety systems will be undertaken to develop a list of components which have potential for causing safety system actua-tions.
Included in the format of this list will bei equipment identifica-tion numbers, appropriate plant schematic and drawing numbers and a description of the potential type of safety system actuation.
If feasible, this list will then be incorporated into the Advanced Maintenance Management System (AMMS) database such that discipline Work order Planners, Engineers preparing / performing Facility or Specification Changes and Operations personnel are alerted to potential safety system actuations when planning modifications, work orders, tagging orders and releasing work orders for repair. This list will be developed by a working group comprising all appropriate plant disciplines. Their review will encompass all safety systems and include a review of past Corrective Action Documents involving safety system actuation. After development of thi6 list, discipline plannern will be flagget to obtain a second level review of plans for work and post maintenance testing.
A secondary output of this group will be the recommendation for additional blocks to prevent safety system actustion during maintenance and testing activities.
Date When Full Compliance Will lie Achieved
'These corrective actions are anticipated to begin approximately 30 days after Palisades resumes power operation.
Initiation of corrective actions are being delayed until this time due to experienced personnel necessary OC0287-0213-NLO4 i
r Nuclear Regulatory Commission 3'
Palisades Plant Response to IEIR 86-032 Revision 2 February 6,1987 for adequate completion being committed to plant testing and start-up operations. A detailed sequence of actions will be submitted approximately 60 days after Palisades resumes power operation. Full compliance is expected to be achieved approximately six months after initiation of these corrective actions.
