UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO.
TO FACILITY OPERATING LICENSE NO. NPF-69 NIAGARA MOHAWK POWER CORPORATION NINE MILE POINT NUCLEAR POWER STATION UNIT NO.
2 DOCKET NO. 50-410
- 1. 0 INTRODUCTION In a letter dated April 3, 1990, Niagara Mohawk Power Corporation (the licensee) requested an amendment to the Nine Mile Point Unit 2 (NMP2) Operating License NPF-69.
The proposed amendment requested the deletion of License Condition.
2.C(9) which addresses the Detailed Control Room Design Review (DCRDR) at NMP2 and the associated Human Engineering Discrepancies (HEDs).
As a result of the staff's review of the April 3, 1990, letter, additional information was requested on May 15, 1990, by the NRC staff concerning the remaining HEDs to be corrected per License Condition 2.C(9).
The licensee submitted a letter to the NRC dated June 29, 1990, providing the additional information requested.
- 2. 0 EVALUATION License Condition 2.C(9) reads as follows:
(9) Detailed Control Room Desi n Review Section
- 18. 1 SSERs 5-and 6
(a)
Niagara Mohawk Power Corporation shall implement the activities remaining to complete the Detailed Control Room Design Review and correct all human engineering discrepancies (HEDs) in accordance with the schedule and commitments in letters from C.V. Mangan (NMPC) to E.G.
Adensam (NRC) dated April 14 and June 9, 1986.
(b)
Prior to startup following the first refueling outage, Niagara Mohawk Power Corporation shall provide the results of the re-evaluation of normally lit and nuisance alarms for NRC review in accordance with its August 21, 1986, letter.
(c)
Prior to star tup following the first refueling outage, Niagara Mohawk Power Corporation shall complete permanent zone banding of meters in accordance with its August 4, 1986, letter.
As a result of several telephone conversations between the licensee and the staff, the staff concludes that parts (b) and (c) of License Condition 2.C(9) need not be deleted at this time, since it is the licensee's intention to P0 fQPf0039 90i2f8 PDR ADOCN, 05000@f0 p

A complete parts (b) and (c) consistent with the original proposed resolutions and on the original schedule in accordance with the August 21, 1986, and August 4, 1986, letters.
Therefore, parts (b) and (c) are not being deleted at this time.
Parts (b) and (c) may be deleted at a later time following a certification by the licensee that the subject actions have been implemented.
The deletion of part (a) is addressed below.
License Condition 2.C(9) part (a) references two letters which identify specific HEDs.
Included in the letters are descriptions of the HEDs, explanations of the corrections and schedules for implementation.
Any change to the attributes of an HED referenced in these letters would require an amendment to the license condition.
The licensee has indicated that they are comnitted to resolve all the HEDs in License Condition 2.C(9) part (a) in accordance with the DCRDR requirements of NUREG-0737, Supplement 1.
The purpose of requesting the deletion of License Condition 2.C(9) part (a) is to remove the necessity for the processing of multiple revisions to the license condition as a result of changes to the method of correction of the HEDs.
.x" Several phone calls between the NRC staff and the licensee have been made to ~
discuss changes to the originally planned corrections of HEDs.
As a result of these calls, all changes to date have been evaluated by the staff and have been determined to be acceptable and will be reflected in a Supplemental Summary Report to be submitted by the licensee.
The licensee will submit a docketed DCRDR Supplemental Summary Report 6 months following the restart of NMP2 from the 1990 refueling outage for staff review.
This report will contain copies of each of the revised HED sheets.
Further revisions to HEDs, if they occur, will also be submitted to the NRC in subsequent Supplemental Sumary Reports.
The docketed Supplemental Summary Report will provide sufficient opportunity for staff review and, therefore, a revision to the License Condition 2.C(9) part (a) for each of these changes is unnecessary.
3.0
SUMMARY
The staff concludes that part (a) of License Condition 2.C(9) may be deleted since a mechanism, as discussed above, is currently in place for the NRC staff to monitor and review changes to HEDs.
Parts (b) and (c) of License Condition 2.C(9) may be deleted at a later time following a certification by the licensee that the subject actions have been completed.

- 4. 0 ENVIRONMENTAL CONSIDERATION This amendment involves a change in a requirement with respect to the installation or use of the facility components located within the restricted areas as defined in 10 CFR Part 20.
The staff has determined that this amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure.
The Commission has previously issued a proposed finding that this amendment involves no significant hazards consider ation and there has been no public comment on such finding.
Accordingly, this amendment meets the eligibilitycriteria for categorical exclusion set forth in 10 CFR Sec 51.22(c)(9).
Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.
5.0 CONCLUSION
We have concluded, based. on the considerations discussed above, that:
(I) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed
- manner, and (2) such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
