Pursuant to 10 CFR 50.4(b)(6) and 50.71(e), Niagara Mohawk Power Corporation hereby submits one signed original and ten copies of Revision 1 to the Nine Mile Point Unit 2 Updated Final Safety Analysis Report, hereinafter referred to as the Updated Safety Analysis Report (USAR) for Nine Mile Point Unit 2.. Copies are also being sent directly to the Regional Administrator, Region I and the NRC Resident Inspector at Nine Mile Point. In accordance with 10 CFR 50.71(e)(4) this update includes modifications completed prior to April 30, 1989.

The certificate required by 10 CFR 50.71(e)(2) is attached to this letter, All errata items identified in Attachment to our previous USAR 1

transmittal letter of April 28, 1989, have been resolved and the appropriate changes incorporated into this update. However, as we noted in our previous transmittal letter, Niagara Mohawk's internal Nuclear Compliance and Verification group conducts an additional independent verification of the technical basis of'hanges and the accuracy of the USAR changes. This verification of certain USAR changes for both this update and the original submittal has not been completed, The remaining open verification items fall into one of four categories:

1). The majority of open verification items involve inconsistencies in the level of detail shown on USAR figures when compared to the source design documents. These items do not involve questions of accuracy, but will require development of standards and revision of a large number of design drawings to satisfy NHPC's internal verification procedures.

2). Several verification items relating to setpoints on USAR figures are still being completed. These items have raised questions about setpoints contained in the USAR. Procedures are in place, including 10 CFR 50.59 evaluations, to ensure adequate control of setpoint changes in the plant; however, setpoints on Logic Sketches (LSKs) in the USAR are not routinely updated. Setpoints shown on LSKs are provided as guide values and are not as-built. This is identified on the USAR figures by notes that state: Setpoints shown on logic drawings are for logic clarification only and may be only approximations of the actual process setpoints. Setpoint data sheets must be referred to for actual process setpoints. A small number of the setpoints in the USAR text were originally verified using the design LSKs. There is, therefore, the possibility that these setpoints are also not as-built. A program is now being developed to verify setpoints in the text against the as-built values.

3). Some items from this update (Revision 1) are still in the final verification process.

4). Source documentation for changes developed by GE had not been available, preventing final verification.

Programs to resolve the general arrangement and setpoi nt issues will be established no later than November 30, 1989. A schedule for completion of the programs and all open verification items including any open items from 3 and 4 above wi 11 be established at that time. As stated in our April 28, 1989 submittal letter, procedures are in place to document and resolve verification comments. USAR changes resulting from those comments will then be incorporated.

Attachment 1 is being submitted in fulfillment of the requirements of 10 CFR 50,71(e)(2)(ii) to identify changes made under the provisions of 10 CFR 50.59 but not previously submitted to the Commission. Included in Attachment 1 are eight safety evaluations which were inadvertently left out of our April 28, 1989 submittal. Four of these safety evaluations reflected changes made to the design of the plant prior to the issuance of the full-term operating license. The other four should have been included as changes for the last submittal. All eight safety evaluations were incorporated into Revision 0 to the USAR. None of the safety evaluations in Attachment 1 involved an unreviewed safety question as defined by 10 CFR 50.59(a)(2).

SUMMARY

SER NO.: 89-038 SER TITLE: Revisions to USAR Table 9.4-1 SYSTEM: NA USAR SECTIONS USAR Table 9.4-1, pages 1, 2, and 3 AFFECTED:

DESCRIPTION: This SER documents changes to USAR Table 9.4-1. The foot-note describing the design basis for maximum indoor tem-peratures for safety-related equipment was expanded to include "and the summer outdoor'design maximum temperature of 100'F dry bulb and 73'F wet bulb." Added "cable chases and corridors" under the control building el 261 ft as a separate area on page 1 of the table to reflect the in-crease from 104'F to 110'F inside design maximum tempera-ture for these areas. The increase in indoor temperature is a result of using the higher outdoor air temperature as a design basis.

These changes provide greater flexibility for plant opera-tion by revising acceptable temperature ranges. The in-crease in the plant outside air design temperature from .

93'F to 100'F provides reasonable assurance that the out-door ambient temperature will not result in a plant shut-down in the future. This change will not increase the probability of equipment malfunction or failure, since the safety-related equipment located in the control building el 261 ft cable chases and corridors are qualified for the ambient conditions which were revised from 104'F to 110'F.

These changes have no impact on plant safety and therefore do not constitute an unreviewed safety question.

SUMMARY

SER NO.: 89-039 SER TITLE: Miscellaneous Changes to the USAR NA SYSTEM'SAR SECTIONS AFFECTED: Figures 9.2-7 (Sheet 9) and 11.4-1a DESCRIPTION: In order to eliminate a nuisance alarm caused by high ambient temperatures, the water treatment system caustic storage tank high temperature switch setpoint was increased from 80'F to 90'F, (Figure 9.2-7, Sheet 9). At this new setting, the high temperature switch will continue to perform its design function which is to provide indication of overheating by the tank's plate heating coil.

Two radioactive solid waste system check valve sym-bols were revised from "socket weld" to "flanged" end connections as the result of a change in valve type (piston check to swing check). The change was made to minimize the potential for valve failure due to particles present in the system fluid and to facili-tate valve removal for maintenance. The design func-tion of these valves remains unchanged.

These changes are within the design basis of the plant and do not affect any safety functions or anal-ysis, and therefore do not constitute an unreviewed safety question.

AFFECTED: Tables 9.2-1A, Sheets 1, 5, and 6; 9.2-1B, Sheets 1 and 5; and 9.2-2, Sheets 1, 5, and 9

'ESCRIPTION: These changes to the USAR tables are a result of an editorial omission discovered during the review of SER 88U-014, Revision 0, Service Water System Modifi-cations. The change to the service water flow re-quirements made in the affected tables is consistent with the change described on SER 88U-014 to provide continuous flow to four of the safety-related unit coolers serving the residual heat removal and low pressure core spray pump rooms. Therefore, these-changes update the USAR tables to incorporate a previously approved plant modification. The review concluded that the changes do not constitute any unreviewed safety questions, 5018-176720183-HC4
