Dear Mr. Mueller:
The NRC staff is reviewing your application for license amendment, dated October 16, 1998, to change the format and content of the current Technical Specifications (TSs) for Nine Mile Point Nuclear Station, Unit 2 (NMP2) to be generally consistent with NUREG-1434, Revision 1, "Standard Technical Specifications for General Electric Plants, BWR 6," and extend surveillance requirements from 18 to 24 months.
Based upon our review of the changes proposed for TS Sections 3.1 and 3.2, we find that additional information, identified in the enclosure, is needed.
The schedule for responding to this, letter was discussed with Messrs. S. Leonard and T. Page in your organization.
Based upon that discussion, a mutually agreeable response date is May 13, 1999.

3/99 NINE MILEPOINT NUCLEAR STATION, UNIT2 IMPROVED TECHNICALSPECIFICATIONS SECT 3.1 - REACTIVITYCONTROL SYSTEMS RAI 3.1-4 ITS 3.1.7 Standby Liquid Control System SR 3.1.7.8 & SR 3.1.7.9 CTS 4.1.5.d DOC L.2 The DOC L.2 states that the requirement that CTS 4.1.5.d (SR 3.3.1.7.8 8 SR 3.1.7.9) "be performed during shutdown is proposed to be deleted... might be able to be performed while operating without jeopardizing safe plant operation."
Comment: This relaxation is not supported by the Bases for SR 3.3.1.7.8 & SR 3.1.7.9, which state that the "Frequency is based on the need to perform this Surveillance under the conditions that apply during a plant outage and the potential for an unplanned transient if the surveillance wereperformedatpower."
The ITS SR 3.3.1.7.88 SR3.1.7.9frequencyisproposedtobe24 months, the refueling cycle interval ~ The DOC L.2 needs to be corrected.
NMPC Response:
Enc1osure
RAI 3.1-6 ITS 3.1.8 SDV Vent and Drain Valves SR 3.1.8.3, SR Frequency CTS 4.1.3.1.4.a DOC LD.1 Cyclic Surveillance Frequency is proposed to be changed from 18 to 24 months.
Comment: Under review by the NRC Technical Staff.
NMPC Response:
[No response required at this time; NRC Technical Staff is reviewing]
RAI 3.1-7 ITS 3.1.8 SDV Vent and Drain Valves, Required Action A.1 CTS 3.1.3.1.d DOC L.1 &JFD1 The CTS requires restoring an SDV vent or drain line with one inoperable valve to operable status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
The STS requires restoring an SDV vent or drain line with one inoperable valve to operable status within 7 days.
The ITS requires isolating an SDV vent or drain line with one inoperable valve within 7 days.
NMPC justifies this based upon WNP2 and LaSalle approved TS, and NMP2 design being similar to those plants.
Comment: Changes to both the CTS and STS are beyond scope changes that require NRC Technical Staff review.
NMPC Response:
[No response required at this time; NRC Technical Staff is reviewing]
3/99 NINE MILEPOINT NUCLEAR STATION, UNIT2 IMPROVED TECHNICALSPECIFICATIONS SECT 3.2 - POWER DISTRIBUTIONLIMITS RAI 3.2-1 ITS 3.2.4 Average Power Range Monitor (APRM) Gain and Setpoint ITS 3.2.'4 LCO & SR 4.2.4.2 STS,3.2.4 Average Power Range Monitor (APRM) Gain and Setpoint CTS 3/4.2.2 Average Power Range Monitor Setpoints DOC A.4 and JFD-3 In the CTS the APRM flow biased simulated thermal power scram setpoint is established in the COLR, according to a relationship ('T'). This relationship is returned to the ITS because it "is not cycle specific." This change results in the ITS 3.2.4 L'CO & SR 4.2.4.2 including additional detail that is not in the STS.
Comments:
(1) While it is agreed that the proposed change is administrative, the detail removed from the COLR and placed in the ITS, is in the COLR under both the CTS and.STS.
The rationale for utilizing the COLR is that, while the relationship 'T's not cycle specific it does vary and it can be defined and determined external from the specification. The details add significantly to the specification, particularly ITS SR 4.2.4.2.
Reconsider returning the information to the COLR. Or, in the case of ITS SR 4.2.4.2, consider placing the detail in the Bases.
(2) The phraseology, ".;. the ratio of FRTP and MFLPD," while it may be grammatically correct, is not clear.
Preferable is, "... the ratio of FRTP:MFLPD," or
"... the ratio FRTP/MFLPD." Consider rewording for clarity.

NMPC Response:
RAI 3.2-2 B 3.2.1 Average Planar Linear Heat Generation Rate (APLHGR)
Bases Sections: Background &Applicable Safety Analysis JFD-1 The. ITS Bases, B 3.2.1, for APLHGR limits do not include the STS Bases discussion on anticipated operational occurrences (AOOs), because "AOOs are not considered in establishing the APLHGR limits (the MCPR and LHGR limits are considered for AOOs)."
Comment: In confirming this JFD-1 justification with the NRC's Reactor Systems Technical Staff, it seems this change is generically correct.
Request that a TSTF change request be submitted to revise the STS.
NMPC Response:
NMPC to submit TSTF Change proposal (per verbal response on 3/11/99; no additional response required).
