By this letter, we are reporting specific items in our OfI Action Plan response which will not be implement.ed on the schedule submitted by BG&E letters on this subject dated December 15 and 30, 1980, and July 3, 1981. The attachment to this latter provides revised and more detailed schedules together with an indication of progress to date.

Feference requested notification of any technical deviations from NRC positions on Action Items II.F.1.1 and II.F.1.2. We expect to comply with the IEC positions, but we are reevaluatirg to verify that no unanticipated deviations have been imposed by the hardware ve have procured. We vill notify you immediately if any requirement is not

! appropriately addressed.

Other systems which will be insta13ed and tested within the l original schedule may lack specified qualification. These iteme are included

in our equipment qualification program and vill he addressed thmegh responses to Inspection and Enforcement Bulletin 79-01B. This allows a more orderly, efficient, and effective qualification program for equipment at our plant.

l l If any additional information is required, we vould be pleased l to provide iteto you.

Very truly. our , b

i ATTACHMENT l

l Item II.B.3 Post Accident Sampling System At present, the sample skid is on site. Placement is scheduled in late October. Terminations, ductwork, and piping erection vill continue-through November for nost equipment, but. vill extend'through December for several solenoid valves scheduled for delivery on 11/30/81. Final installation, calibration and testing vill carry through January 1982, and shielding vill be installed by March 1982.

The items above must be. completed serially. Testing schedules-near the end of the year are extremely crowded, precluding an accelerated test program to complete this item before 1/1/82. We expect'to be able to report completion of installation and testing by 3/1/82. . If any further schedule changes are required, we vill report them by 2/1/82.

Item II.F.1.1 Noble Gas Stack' Monitor Tubing, conduits and skids are now being installed. "his effort vill be completed by mid-December 1981. -

Detector calibration and testing vill take approximately one month in each unit, so we vill be finished by the end of February 1982.

We expect to be able to report completion by 3/15/82. Any change to the above schedule vill be reported by 2/1/82.

l Item II.F.1.2 Noble Gas Steam Effluent Monitor Engineering for this item is nearly complete; however, ,

unexpectedly long lead times for equipment delivery have imposed delays, the extent of which is still uncertain. We now expect to receive the detector shielding in early Decenber and ';he detect. ors themselves in January. If these delivery dates are maintained, installation of the entire system in both units vill take until early June. By staggering installation, testing and training for Unit 1 and 2, we expect to be able to report comnletion by 7/1/82.

j Item II.F.1.6 Containnert Hydrogen Monitoring l'

Sequencing and recording equipment will not be delivered until early December. Because current Technical Specifications make implementatica--

, of this requirement impractical, a request for their modification has been

! submitted and must be cpproved before either existing H2 analyzer is removed from service.

, Item II.F.1.6' Containment IIydrogen Monitoring (continued)

Equipment installation and analyzer testing must be staggered ~

to maintain continuous hydrogen monitoring capability. Installation includes extensive piping modifications and is expected to take more than four weeks. Testing and training vill require several additional weeks per unit. We expect to report completion by h/5/82.
