Subject:
James A. FitzPatrick Nuclear Power Plant Docket No. 50-333 Integrated Implementation Schedule of SPDS and ATWS Rule Modifications
Reference:
1.
10 CFR 60.62, " Requirements for Reduction of Risk from Anticipated Transients Without Scram (ATWS) Events for Light-Water-Cooled Nuclear Power Plants" (49 FR 26036).
Dear Sir:
On January 29, 1985, Authority representatives met with the NRC staff to discuss our implementation of the five items in Supplement No. 1 to NUREG-0737.
At that meeting, we briefly described an alternate schedule for SPDS and the ATWS rule (Reference No. 1).
This letter provides the details of this alternate plan.
The Authority has re-examined the schedule provided for the Safety Parameter Display System (SPDS) considering the modifications required to implement the ATWS Rule (Reference 1).
Although the ATWS Rule does not require that an implementation schedule be submitted until 180 days after the issuance of the final QA guidance, the combined impact on the Authority's resources of these issues requires that we address them together.
The Authority proposes a schedule in which SPDS implementation is accelerated by one refueling cycle (approximately eighteen months).
This schedule improvement is possible only if ATWS Rule related modifications can be scheduled for completion thirty days after the end of the third refueling outage after July 26, 1984 (i.e. Reload 8/ Cycle 9) or June 1, 1988 whichever is later.
This represents a one fuel cycle extension of the schedule for ATWS modifications from the schedule in the ATWS rule.
The SPDS would then be completed thirty days after the end of the 1986 (Reload 7/ Cycle 8) refueling outage or December 31, 1986, whichever is later.
The accelerated SPDS schedule proposed by this letter is contingent upon the NRC's approval of the attached ATWS schedule.
Without approval, the SPDS schedule remains unchanged from that previously submitted.

Attacha2nt No. 1 is th2 Authority's schsdule for the coupletion of ATWS modifications as required by 10 CPR 50.62(d).
This schedule was prepared without the selection of a specific alternative or plant unique analyses.
Therefore, with the exception of the final completion date, the details may change.
A final ATWS implementation plan will be submitted October 15, 1985 in accordance with the requirements of the rule.
By providing schedules linked to refueling outages, NYPA has considered the need for scheduled refueling outages to complete equipment installation.
Linking the schedule to a fixed date also considers the possibility that mid-cycle outages may be cancelled resulting in a refueling outage taking place sooner than anticipated.
If this were to occur, and the schedule were based i
solely on the refueling outage, unavoidable schedule extensions may be necessary.
i i
}
This is both a realistic and best schedule for many reasons.
At our January 29th meeting, the Authority described the modifications j
scheduled for installation in upcoming refueling outages.
(A list of these modifications is included as Attachments No. 2 and 3).
1 While none of these modifications are of such scope or size as to preclude the completion of other modifications, the number which can be safely and effectively implemented at one time is limited.
i Physical limitations, such as on-site manpower, as well as fiscal, engineering and procurement limitations can significantly affect schedule.
In some cases, installation sequences can be changed to improve schedules, reduce the amount of duplicate work or to take r
advantage of developing situations.
Schedule flexibility allows the Authority to both operate FitzPatrick and complete modifications in i
l an efficient, safe and cost-effective manner.
We are actively working towards an integrated schedule that will clearly illustrate the amount of work planned, as well as our progress.
The Authority has been closely following the ATWS rule; we have participated in the BWROG's (Boiling Water Reactor Owners Group)
ATWS generic program since it's inception.
The generic portion of this program was recently completed (March 1985).
The Owners Group i
is still examining Standby liquid Control System alternatives. (e.g.
1 enriched boron, increased boron concentration and two-pump l
operation) and technical specification changes for the various options.
If you have any questions or would like to discuss this further, please contact Mr. J. A. Gray, Jr. of my staff.
Very truly yours, I
