Inspection Report 50-285/85-25 dated January 29, 1986.
Dear Mr. Gagliardo:
Inspection Report 85-25 Omaha Public Power District recently received Reference 2.
This Inspec-tion Report concerned an inspection held during the period November 4-8, 1985, in the area of the radiation protection program.
During this in-spection, the NRC discussed the status of the Noble Gas Effluent Monitor midrange and high range detector systems and the FCS Technical Specifica-l tion Section 2.21 requirements.
Technical Specification Table 2-10 requires that when less than the mini-mum number of channels are operable, alternate methods for monitoring be initiated and if the channels are not returned to operating status within 7 days, a special report shall be submitted within 14 days to the Commis-sion containing plans and schedules for returning the monitors to opera-ble status. At the time of the inspection, the midrange and high range detector systems had not been calibrated. We provided the inspectors j
with a copy of OPPD letter LIC-84-301 dated September 5, 1984, which pro-i vided our plans for returning the monitors to operable status by Septem-her 14, 1984. Additionally, we informed the inspectors that a second i
letter was sent after Se)tember 5,1984, which extended tha date of ex-pected operability for t1e monitors. At the time of the inspection, we i
were unable to locate the second letter.
The NRC inspectors stated that this was considered an unresolved item (285/8525-02) pending resolution of the notification to the Commission and expected operability of the monitors. OPPD has subsequently deter-mined that the second letter was never sent to the NRC.
Therefore, this letter serves to provide the information required by the Technical Spect-fications.

. b.'E.Gagliardo LIC-86-095 Page 2 Monitors RM-063 L, M, and H are inoperable because they have not been
~
calibrated at the required. frequency. The current calibration procedure requires the use of secondary (solid) radioactivity sources that directly relate to the high range primary gas calibration done by the manufacturer at the factory. Those secondary sources were mistakenly discarded.
Therefore, the current calibration procedure cannot be performed.
The plan for returning RM-063 L, M, and H to operable status requires 'per-forming an onsite, high range primary gas calibration. Calibration design and procedure revision is expected to be complete by March 14, 1986.
Pro-curement of radioactive gas standards and subsequent performance of the calibration should be completed by May 15, 1986.
Performance of the high range primary gas calibration will be done in conjunction with a second-ary calibration using solid sources. The secondary calibration would 4
then be repeated at the Technical Specification required frequency using the same solid sources to relate back to the primary calibration.
