SUBJECT:

Nine Mile Point Nuclear Station Unit No. 2; Docket No. 50-4 10 License Amendment Request for Adoption of TSTF-484, Revision 0, "Use of TS 3.10.1 for Scram Time Testing Activities" In accordance with the provisions of Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR 50.90), Nine Mile Point Nuclear Station, LLC (NMPNS) is submitting a request for an amendment to the technical specifications (TS) for Nine Mile Point Unit 2 (NMP2), Renewed Operating License No.

NPF-69.

The proposed amendment would revise Limiting Condition for Operation (LCO) 3.10.1 to expand its scope to include provisions for temperature excursions greater than 200°F as a consequence of inservice leak and hydrostatic testing, and as a consequence of scram time testing initiated in conjunction with an inservice leak or hydrostatic test, while considering operational conditions to be in Mode 4. This change is consistent with NRC approved Revision 0 to Technical Specification Task Force (TSTF) Improved Standard Technical Specification Change Traveler, TSTF-484, "Use of TS 3.10.1 for Scram Time Testing Activities." The availability of the TS 3.10.1 revision was announced in the Federal Register on October 27,2006 (71 FR 63050) as part of the consolidated line item improvement process (CLIIP).

Attachment (1) provides an evaluation of the proposed change. Attachment (2) provides the existing TS pages marked up to show the proposed changes. Attachment (3) provides the existing TS Bases pages marked up to show the changes associated with the proposed amendment (for information only). The TS Bases changes will be processed in accordance with the NMP2 TS Bases Control Program (TS 5.5.10).

NMPNS requests approval of the proposed license amendment by February 29, 2008, with the amendment being implemented within the subsequent 60 days.

In accordance with 10 CFR 50.9 1, a copy of this application, with attachments, is being provided to the designated New York state official.

System Leakage and Hydrostatic Testing Operation B 3.10.1 B 3.10 SPECIAL OPERATIONS B 3.10.1 System Leakage and Hydrostatic Testing Operation BASES BACKGROUND The purpose of this Special Operations LC0 is to allow certain reactor coolant pressure tests to be performed in MODE 4 when the metallurgical characteristics of the reactor pressure vessel (RPV) require the pressure testing at temperatures > 200°F (normally corresponding to MODE 3 Hydrostatic testing and system leakage pressure tests required by Section XI of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (Ref. 1) are performed prior to the reactor going critical after a refueling outage. Recirculation pump operation, decay heat, and a water solid RPV (except for a gas bubble for pressure control) are used to achieve the necessary temperatures and pressures required for these tests. The minimum temperatures (at the required pressures) allowed for these tests are determined from the RPV pressure and temperature (PIT) limits required by LC0 3.4.11, "Reactor Coolant System (RCS) Pressure and Temperature (PK) Limits." These limits are conservatively based on the fracture toughness of the reactor vessel, taking into account anticipated vessel neutron fluence.

With increased reactor vessel fluence over time, the minimum allowable vessel temperature increases for a given pressure.

Periodic updates to the RCS PIT limit curves are performed as necessary, based on the results of analyses of irradiated reactor vessel material data. Hydrostatic and system leakage eventually be required with minimum reactor coolant temperatures > 200°F.

exception to MODE 3 requirements, including OPERABILITY of primary containment and the full complement of redundant Emergency Core Cooling Systems (ECCS). Since the tests are performed nearly water solid (except for a gas bubble for pressure control),

at low decay heat values, and near MODE 4 conditions, the stored energy in the reactor core will be very low. Under (continued)

Furthermore, the purpose is to allow continued performance of control rod scram time testing required by SR 3.1.4.1 or SR 3.1.4.4 if reactor coolant temperatures exceed 200°F when the control rod scram time testing is initiated in conjunction with a system leakage or hydrostatic test. These control rod scram time tests would be performed in accordance with LC0 3.10.4, "Single Control Rod Withdrawal - Cold Shutdown," during MODE 4 operation.

INSERT B (for TS Bases page B 3.10.1-1)

However, even with required minimum reactor coolant temperatures < 200°F, maintaining RCS temperatures within a small band during the test can be impractical. Removal of heat addition from recirculation pump operation and reactor core decay heat is coarsely controlled by control rod drive hydraulic system flow and reactor water cleanup system non-regenerative heat exchanger operation. Test conditions are focused on maintaining a steady state pressure, and tightly limited temperature control poses an unnecessary burden on the operator and may not be achievable in certain instances.

The hydrostatic and/or RCS system leakage tests require increasing pressure to approximately 1025 psig. Scram time testing required by SR 3.1.4.1 and SR 3.1.4.4 requires reactor pressures

> 800 psig.

Other testing (e.g., excess flow check valve testing) may be performed in conjunction with the allowances for system leakage or hydrostatic tests and control rod scram time tests.

Additionally, even with required minimum reactor coolant temperatures < 200°F, RCS temperatures may drift above 200°F during the performance of system leakage and hydrostatic testing or during subsequent control rod scram time testing, which is typically performed in conjunction with system leakage and hydrostatic testing. While this Special Operations LC0 is provided for system leakage and hydrostatic testing, and for scram time testing initiated in conjunction with a system leakage or hydrostatic test, parallel performance of other tests and inspections is not precluded.
