1.0 DESCRIPTION
The proposed License amendment extends the completion time from 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for Condition B of Technical Specification (TS) 3.5.1, "Accumulators."
The changes are consistent with NRC approved Industry/Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler, TSTF-370, "Risk Informed Evaluation of an Extension to Accumulator Completion Times for Westinghouse Plants." The availability of this technical specification improvement was announced in the Federal Register on March 12,2003 as part of the consolidated line item improvement process (CLIIP).
2.0 ASSESSMENT
2.1 Applicabilitv of Published Safety Evaluation Entergy Nuclear Operations Inc. (ENO), has reviewed the safety evaluation published on July 15,2002 (67 FR 46542) as part of the CLIIP. This verification included a review of the NRC staff's evaluation as well as the supporting information provided to support TSTF-370 (i.e.,
WCAP-15049-A, "Risk-Informed Evaluation of an Extension to Accumulator Completion Times," dated May 18, 1999). ENO has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to Indian Point 3 and justify this amendment for the incorporation of the changes to the Indian Point 3 Technical Specifications.
2.2 Optional Changes and Variations ENO is not proposing any variations or deviations from the technical specification changes described in TSTF-370 or the NRC staff's model safety evaluation published on July 15, 2002.

Accumulators B 3.5.1 BASES ACTIONS A.1 (continued) the core subcritical. One accumulator below the minimum boron concentration limit, however, will have no effect on available ECCS water and an insignificant effect on core subcriticality during reflood. Boiling of ECCS water in the core during reflood concentrates boron in the saturated liquid that remains in the core.
In addition, current analysis techniques demonstrate that the accumulators do not discharge following a large main steam line break.
Even if they do discharge, their impact is minor and not a design limiting event.
Thus, 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> is allowed to return the boron concentration to within limits.
- u If one accumulator is inoperable for a reason other than boron concentration; the accumulator must be returned to OPERABLE status
,i hour'an this Condition, the required contents of three
(,it Y,accumulators cannot be assumed to reach the core during a LOCA.
Due to the severity of the consequences should.a LOCA occur in these conditions, theohour Completion Time to open the valve, remove powerto the valve, or restore the proper water volume or nitrogen cover pressure ensures that prompt action will be taken to return the
(
it.
- )
inoperable accumulator to OPERABLE status.
The Completion Time minimizes the potential for exposure of the plant to a LOCA under If the accumulator cannot be returned to OPERABLE status within the associated Completion Time, the plant must be brought to a MODE in which the LCO does not apply.
To achieve this status, the plant must be brought to MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and reactor coolant pressure reduced to < 1000 psig within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.

INDIAN POINT 3 B 3.5.1 - 7 Revision 0
Accumulators B 3.5.1 BASES SURVEILLANCE REQUIREMENTS SR 3.5.1.4 (continued) inleakage. Sampling the affected accumulator within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after an increase of 8.4 cubic feet will identify whether inleakage has caused
,a reduction in boron concentration to below the required limit.
Considering the nominal accumulator volume of 795 cubic feet of water, inleakage of 8.4 cubic feet of pure water would result in a boron concentration reduction of approximately 1X.
An increase in the accumulator volume of 8.4 cubic feet causes a change of approximately 10% in the indicated accumulator level.
It is not necessary to verify boron concentration if the added water inventory is from the refueling water storage tank (RWST).
because the water contained in the RWST is within the accumulator boron concentration requirements.
This is consistent with the recommendation of NUREG-1366 (Ref.(&.
SR 3.5.1.5 Verification every 31 days that power is removed from each accumulator discharge isolation valve operator when the reactor coolant system pressure is > 2000 psig ensures that an active failure could not result in the undetected closure of an accumulator motor operated isolation valve.
If this were to occur, only two accumulators would be available for injection given a single failure coincident with a LOCA. Since power is removed under administrative control, the 31 day Frequency will provide adequate assurance that power is removed.-
This SR allows power to be supplied to the motor operated discharge isolation valves when reactor coolant system pressure is < 2000 psig.
thus allowing operational flexibility by avoiding unnecessary delays to manipulate the breakers during plant startups or shutdowns.
Should closure of a valve occur, the SI signal provided to the valves would open a closed valve in the event of a LOCA.
