9 APPENDIX B NOTICE OF DEVIATION Based on the results of an NRC inspection conducted during the period October 24, to December 2,1981, it appears that one of your activities was not conducted in conformance with your commitments to the consaission as indicated below:
Final Safety Analysis Report (FSAR) section 7.1.2.2.3 specifies that the total worst case error produced in the reactor outlet temperature trip channel, which includes sensor, processing equipment and trip bistable errors, will not exceed 11.0*F.
Contrary to the above, the procedure used to calibrate the reactor outlet temperature trip channel allows acceptance of a total error of i 3.065*F.
This total includes a sensor error of + 0.065*F, a process error of +2.5 F, and a bistable error of 10.5*F.
In addition, the 1 3.065*F does not include the readability error of the signal converter meter used to calibrate the process equipment.
