Dear Mr. Clark:
Subject:
Implementation Schedule on Selected TMI Related Modifications Omaha Public Power District's letters to the Commission dated November 19, 1981 and December 28, 1981 identified the District's expected schedule for implementing several NtIREG-0737 required modifications at the Fort Calhoun Station.
Specifically, tasks II.B.2, II.B.3, II.F.1.1 and II.F.1.2 were delayed due to equipment delivery and construction problems.
These four tasks have experienced additional delays. The explanation for these deiays and revised schedules are attached.

ATTACHMENT 1 Task Action Plan Item II.B.2:
Plant Shielding NUREG-0737 Required Completion Date:
January 1,1982 Present Status and Reasons for Delay:
This task was expected to be complete by April 1,1982, as detailed in the District's letter dated December 28, 1981.
However, because of difficulties experienced during the construction phase, part of this work will be delayed by approximately one month. This task consists of-construction of new shield walls in three different areas and. install-ation of remote level indicators for SI pump room sumps. The present status of these jobs is as follows:
1.
Shield Wall Near Control Room:
Construction work is almost complete; only painting and finishing. work remains.
2.
Shield Wall Around Radwaste Panel Area:
Rebar and form work is in place, 50% concrete has been poured; rest of the con-crete is expected to be poured by April 15, 1982.
3.
Shield Wall in Room 59:
Status same as item 2.
4.
SI Pump Room's Level Indicators: Because of an equipment delivery problem, this work could not be finished on schedule.
Construction is expected to be complete by April 15, 1982.
Calibration will take approximately two more weeks.
Expected Completion Date:
April 30, 1982

,i T sk Action Plan Itsn II.B.3: Reactor Coolant Post-Accident Sampling '
NUREG-0737 Required Completion Date:
January 1,1982 Present Status and Reasons for Delay:
This task was expected to be complete by March 31, 1982, as de-tailed in the District's letter dated December 28, 1981. However, because Sf-equipment delivery problems and construction difficulties, particularly inaccessibility of the work, area due to the existing equipment (major portion of this work was in gas compressor room and the existing sampling room), the construction work was completed approxi-mately six weeks behind schedule._'Because of the size of and equipment in the gas compressor and sampling rooms, only a limited number of workers could be effectively used at.any one time.
Installation is no'w complete. At present, the testing and cali-bration work is in progress. Testing, room modifications, and training are expected to take approximately ten more weeks. Allowing another two weeks for contingencies, the' system is expected to be fully operational by June 30, 1982.

ATTACHMENT 3 Task Action Plan Item II.F.1.2:
Sampling System for lodines and Particulates NUREG-0737 Required Completion Date:
January 1, 1982 Present Status and Reasons for Delay:
This task was expected to be complete by March 31, 1982, as de-tailed in the District's letter dated Hovember 19, 1981.
However, the District is having considerable equipment delivery problems. The wide range noble gas monitor and sampling system for particulates and iodines were ordered from Victoreen, Inc.
In accordance with our contract with Victoreen, the guaranteed delivery date for the system was originally.
December 1, 1981.
However, because of a large number of orders received by Victoreen in. response to TMI requirements, Victoreen was unable to meet their guaranteed delivery date.
Inspite of a special trip to Victoreen's office and several telephone calls, the District has not been able to get a firm commitment for delivery date from Victoreen.
Victoreen's tentative delivery date is now May 8,1982.
Installation and testing is expected to take approximately eight weeks. Accordingly, the complete system is expected to be operational by July 8,1982 at the-earliest. Allowing for training and contingencies, the District expects to meet a July 31, 1982 implementation date. As reported earlier, isokinetic nozzles for this system were installed during the last re-fueling outage.
Expected Completion Date:
July 31, 1982 I

ATTACHMENT 4 Task Action Plan Item II.F.1.1:
Main Steam Line Radiation Monitor NUREG-0737 Required Completion Date:
January 1,1982 Present Status and Reasons for Delay:
This task was expected to be complete by April 20, 1982. However, because of equipment delivery problems, particularly from Victoreen, Inc. (see attachment 3), this work is expected to be delayed.
Delivery for main steam line monitors, which was promised by December 15, 1981, is now expected by April 30, 1982.
Solenoid valves are expected by April 30, 1982.
Part of the installation work is complete and it is expected to take approximately five weeks for installation and testing after receipt of materials. Allowing for training and contingencies, I
the system is expected to be operational by June 30, 1982.
Expected Completion Date:
June 30, 1982
