SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO CHANGE IN CHAPTER 14 FSAR STARTUP TEST PROGRAM NIAGRARA MOHAWK POWER CORPORATION NINE MILE POINT NUCLEAR STATION UNIT 2 DOCKET NO. 50-410 1.0 Introduction By letter dated 'September 9,
1987',
Niagara'Mohawk Power Corporation (the licensee) submitted changes made to their initial startup test program.
The submittal was made in accordance with license condition C(8) which requires that any changes to the initial startup test program described in Section 14 of the FSAR be made in accordance with the provision of 10 CFR 50.59 and reported, in accordance with 50.59(b), within one month of such change.
The letter detailed two changes:
(1)
The requirement for RCIC (Reactor Core Isolation Cooling) pump discharge pressure during CST (Condensate Storage Tank) injection testing was changed from 100 (+20,-0) psi above reactor pressure to
> 100 psi above reactor pressure.
(2)
The requirement to test the RWCU (Reactor Water Cleanup) system during test condition heatup at rated reactor pressure and temperature and in both its normal and hot standby (startup) modes was changed to require testing in the startup alignment and in the normal operating alignment.
In addition, the requirement to calibrate the bottom head flow indicator and to measure pump vibration at the coupling end were deleted.

4.0 Evaluation (1)
RCIC Pum Test Pressure 4
To simulate expected operating conditions during Reactor Core Isolation Cooling Condensate Storage Tank (RCIC-CST) injection
- test, the pump discharge pre'ssure must exceed the reactor pressure by an amount that equals or exceeds the maximum pipeline pressure loss during actual vessel injection.
The 'expected maximum pipeline pressure loss during actual, vessel injection is 100 psi.
. ADOCH, 05000410
I
The change removes the upper tolerance limit and permits testing at higher pump discharge pressure which subjects the system to a more stringent test and therefore, bounds expected operational characteristics.
The change is therefore found acceptable.
(2)
RWCU S stem Test The change in wording does not change the modes of operation in which the system will be tested.
The removal of the requirement to conduct these tests during test condition heatup (low power) is-necessary since plant specific restraints do not allow placing, the RWCU system in its normal alignment until reactor power exceed 20K of rated power.
The change is therefore acceptable.
The deletion of the requirement to calibrate the bottom head flow indicator is acceptable since this calibration was accomplished during the preoperational test program.
The deletion of the requirement to measure pump vibration at the coupling end is acceptable due to the pump vibration measurements made on the bearing housing and shaft which provide adequate assurance of acceptable pump performance.
5.0 Conclusion We have concluded, based on the considerations discussed
- above,
( 1) 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 (3) the issuance of this change will not be inimical to the common defense and security or to the health and safety of the public.
