RESPONSE TO IE INSPECTION REPORT 86-023 IE Inspection Report 86-023 dated September 26, 1986, transmitted one viola-tion which requires a response by October 27, 1986. The following is our response to that item.
Violation (255/86023-01)
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 con-trols appropriate to the maintenance circumstances:
(1) On August 15, 1986, Q-listed Work Order No 24606289 controlling the maintenance activity for relocating auxiliary fuses in a station power breakse scq fnadequate such that links that were opened were not recloaed.
l (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 installation of a turbine thrust bearing trip device, was inadequate since it failed to state the opening and reclosing of the link that defeats the automatic diesel generators start.

Palisades Plant Response to IEIR 86-023 October 27, 1986
Response
S Corrective Action Taken and Results Achieved The stated three examples which occurred on August 15, 23 and 27, 1986 were the subject of three Licensee Event Reports; LER 86-026,86-027 and 86-029, respectively. Each of the examples was ultimately the result of personnel error. Counselling of appropriate individuals regarding strict attention to detail has been accomplished.
Administrative procedures have been revised to provide enhanced controls during the maintenance process. Documentation of the following items is now required, when applicable: slide links opened / closed, leads lifted /
landed, blank flanges installed / replaced, spool 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.
Additional guidance for maintenance testing following the completion of a maintenance activity has been established in administrative procedures addressing appropriate methods of verifying the restoration of system /
circuit integrity.
Corrective Actions To Be Taken To Avoid Further Violations None Date When Full Compliance Will Be Achieved Full compliance has been achieved.
