Dear Sir:
The Authority's letter of December 23, 1982 (Reference 1) discussed NUREG-0737 Item II.B.3.2 - Post-Accident Sampling, and scheduled completion of the modification by the end of the Reload 5/ Cycle 6 refueling outage now in progress.
Reference 2 transmitted the Commission's Order confirming our commitment to that schedule.
The Authority has made a good faith effort to meet the commitments in References 1 and 2.
A system developed for the BWR Owners' Group Post-Accident Sampling System (PASS) Subcommittee has been purchased and is currently being installed.
As required by References 1 and 2, the system wil] be fully installed and placed into service before startup.
It will be fully operational with the exception of the dissolved gas portion of the system.
The Authority has encountered problems in the sampling of dissolved gases.
These problems, which are similar to those of other utilities employing the Owners' Group system, include water carryover into the sample vial.
The carryover causes inaccurate gas chromatography readings and could result in significant personnel radiation exposure following an accident.

PDR I
1 The BWR Owners' Group PASS Subcommittee is addressing the problem of water carryover and discussed it at a meeting with the NRC in Bethesda on July 20, 1983.
In the course of that meeting, the Owners' Group informed the NRC that: (1) the accuracy of the current PASS dissolved gas measurement is 40%, at best; and (2) a modification to improve the dissolved gas _ sampling is being
- developed and will be sent to the participating utilities in late October or early November-1983.
The NRC personnel at the meeting agreed that plants such as FitzPatrick, which are scheduled to restart before the corrective modifications are implemented, could start-up and at a later date complete corrective modifications to improve the' accuracy of dissolved gas measurement to be consistent with the post implementation review criteria.
Based on the Owners' Group delivery schedule, the Authority anticipates that the corrective modification will be installed
.by December 31,1983.
It is.our understanding, based on this meeting and conversations with the NRC Licensing Project Manager and Resident Inspector, that the Authority will not be considered in violation of the Confirmatory Order due to this delay.
If you have any questions regarding this matter, please contact Mr.
J.A.
Gray, Jr. of my staff.
