APPENDIX B NOTICE OF DEVIATION i
Commonwealth Edison Company Docket No. 50-373 Docket No. 50-374 As a result of the inspection conducted August 12-14, 26-28, and September 3, 1985, the following deviation in four parts to NRC commitments contained in your LaSalle Unit I letter dated December 22, 1983, were identified:
1.
Commitment - Page 11, Paragraph 5, " Augmented temperature monitoring will be performed... to monitor actual temperatures to assure safety-related equipment does not degrade beyond pre-defined thresholds...."
Attachment A of LAP-820-7 for procedure LLP 84-25 dated July 9, 1984, states that the reason for the special Unit 1 drywell temperature moni-toring program procedure is tu " provide a time table for collecting data regarding temperatures in the Unit 1 drywell thru first refuel."
4 Contrary to the above, monitoring of drywell temperatures using the temporary thermocouples stopped in December 1984.
2.
Commitment - Page 10, Paragraph 3, "A temperature menitoring p,rogram has been defined to evaluate the results from the short term fixes '.
Contrary to the above, adequate documented evaluation of the results was not available for review.
3.
Commitmer;t - Page 14, Paragraph 1.c., "Should the temperature in an area where safety related equipment is located exceed the, limiting temperature on which the 18-month life is based for that equipment, for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, an analysis for continued operation will be completed within seven days or the unit will be temporarily shut down for a visual inspection and i
correction of the anomalous condition (s)".
Contrary to the above, such an ana!ysis was not available for review for various periods of time when the limiting temperature was exceeded for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
4.
Commitment - Annex A, Technical Specification, "The temperature monitoring program will verify that these temperature limits are correlated to Control Room CM Monitors (4).
Contrary to the above, the analysis that was provided to correlate local temperatures in the drywell to alarm setpoints on control room containment monitoring (CM) recorders was found erroneous, 4
