- Area Code 517 788-0550 December 22~ 1979 Director, Nuclear Reactor Regulation Att:
Mr Dennis L Ziemann, Chief Operating Reactors Branch No 2 US Nuclear Regulatory Commission Washington, DC 20555 DOCKET 50-255 - LICENSE DPR PALISADES PLANT -
RESPONSE TO IE INSPECTION REPORT 79-17 Consumers Power Company response to the alleged discrepancies noted in IE Inspection Report 79-17 dated November 21, 1979, is as follows:
Item 1 - Infraction Technical Specification 3.8.1.g requires a check of primary coolant system boron concentration each shift when refueling operations are being performed in the reactor.
Contrary to the above, the licensee failed to check primary coolant system boron concentration during the "A" shift on October 2, 1979, a shift during which refueling operations were being performed in the reactor.
Response to Item 1 Discussion The apparent violation of Technical Specification 3.8.1.g is attributed to two factors:
(1) oversight by the individual assigned to draw the sample, and (2) failure of shift operating personnel to stop refueling operations when it was determined that no boron sample was taken on the shift in question.
Corrective Action Taken and Results Achieved The refueling check sheets for the 1979 refueling outage have been examined, and it has been verified that the PCS boron concentration during both the shifts immediately preceeding and following "A" shift on October 2, 1979, was in speci-fication.
Accordingly, it is concluded that the PCS boron concentration during "A" shift on October 2, 1979, was also within specifications.

Consumers Power Company December 22, 1979 Corrective Action to be Taken to Avoid Further Noncompliance 2
This occurrence has been reviewed with the Chemistry Technicians, and the import-ance of obtaining required samples has been stressed.
This event will also be re-viewed with shif't operating personnel, and the importance of verification of all refueling requirements during refueling operations will be stressed.
Date When Full Compliance Will be Achieved The reviews described above will be completed prior to the next refueling outage.
Item 2 - Infraction Technical Specification 6.8.1.b requires implementation of procedures covering refueling operations.
Procedure FHS0-2, "Refueling Procedure" includes checklist CL A5.14-1, "Refueling Operations Shif't Check Sheet," which states, in part:
"the minimum spent fuel pool/reactor cavity level is one foot below the surface skinuners during fuel handling."
Contrary to the above, the licensee handled fuel on the "A" shifts of October 11 and 12, 1979, when the water level was 1.5 and 2 feet, respectively, below the skimmers.
Response to Item 2 Discussion The failure to properly implement Procedure FHS0-2 resulted from a combination of factors:
(1) a small leak in a steam-generator dam combined with a small leak in the reactor cavity liner resulted in the pool level dropping more rapidly than would be expected under normal refueling conditions; (2) the shift operating personnel failed to halt refueling operations upon discovery of this out of speci-fication condition.
Corrective Action Taken and Results Achieved Repairs have been made to both the lea.king steam generator dam and the reactor cavity liner such that these leakage paths should be eliminated.
Shif't operat-ing personnel will be instructed regarding the significant of verifying that prereq-uisites for refueling are within specifications.
Corrective Action to be Ta.ken to Avoid Further Noncompliance Shif't operating personnel will be trained in refueling procedures prior to Palisades next refueling outage.
Date When Full Compliance Will be Achieved The required training will be completed prior to the next re fueling outage.
