Docket No. 50-285
Dear fir. Clark:
Fort Calhoun Station Containment Hydrogen fionitors (NUREG-0737, Item II.F.1.6)
Omaha Public Power District's letters to the Commission dated March 10 and June 1,1982 detailed a delay in placing the subject hydrogen monitors into operation due to damage that occurred to the analyzer cells during calibration in late 1981.
The District had shipped the damaged analyzer cells to the vendor (Comsip, Inc.) for repair and the repaired analyzer cells were returned to the Fort Calhoun Station on June 14, 1982.
Based on this delivery schedule, the District expected to install, calibrate, and have the hydrogen monitors fully operational by July 1, 1982.
The purpose of this letter is to inform the Commission that an edditional delay has precluded the completion of this NUREG-0737 item.
The hydrogen analyzer cells were received on June 14, 1982 without their respective integrated circuit boards, which are required to pro-vide proper remote (i.e., control room) panel indication.
The District immediately contacted the vendor regarding the missing circuit boards and an investigation by the vendor confirmed that the circuit boards were not shipped with the analyzer cells and that, in fact, one of the circuit boards was still located at the vendor's facility and the other board was presumed lost. Therefore, a new circuit board for one of the District's hydrogen analyzer cells must be fabricated.
Addi tionally,
each circuit board must be individually and electrically matched to a
/
specific hydrogen analyzer cell to provide for proper monitor operation l'
and indication. To facilitate this circuit board and analyzer cell matching, the District returned the analyzer cells to the vendor and the vendor has acknowledged receipt of the returned analyzer cells.
Comsip has stated that several weeks will be required to complete the fabri-cation of a new circuit board and complete the recessary electrical work 8207080105 820701 PDR ADOCK 05000285 P

e Mr. Robert A. Clark LIC-82-251 Page Two on the analyzer cells. Accounting for this time at the vendor, sub-sequent delivery time, and finally allowing approximately ten working days to reinstall and calibrate the hydrogen monitors, the District expects the subject monitors to be operational in three months. The District will inform the Commission when the subject monitors are fully opera tional.
