Background
Millstone Unit 3 requested Westinghouse to perform an evaluation of the Emergency Core Cooling System (ECCS) branchline throttle valves. This evaluation was to address the potential throttle valve erosion concem desenbed in Westinghouse notification letter [ ] *> c. Briefly, this task determined the maximum pressure drop across the presertl installed branchline throttle valves and splits that pressure drop between an onfice and the present installed throttle valve. In the scoping evaluations, it was determined that the head boost provid by the Recirculation S stay Pumps was not previously evaluated, and it was necessary to evaluate and address runout of tw High Head Safety injection (HHSI) pumps and Centrifugal Charging Pumps (CCP) prior to designing the branchline orifices. Westinghouse performed CCP and F HS1 puma runout calculations (References 2, 3 and 4) to establish the system performance requirements for the iHSI and Chargmg/ Safety injection (CHG/SI) systems. While performing these suction boost / runout calculations it was determined to be beneficial to revise the Technical Specifications' surveillance and flow balancing requirements. These changes will rectablish pump performance degradation margin, which was used for system rethrotteling to prevent suction boost runout without a Technical Specification -
change.
Page 1 of 5
i I l Purpose This letter only addresses the Technical Specification data associated with minimum safeguards flow
' data that is input to the Updated Final Safety Analysis Report (UFSAR) accident analyses. The maximum safeguards UFSAR input data was not affected by this effort nor is maximum safeguards data provided in the Technical Specifications. The intent of this letter is to provide the revised
' Technical Specification limits and to document the bases for the present and revised Technical Specification limits.
Bases for the Present Technical Specification The Millstone Unit 3 present Technical Specification limits and the associated Westinghouse ECCS -
calculations / references are as follows:
Survedlance Requirements Pump Current value Reference T/S Section CCP A,B & C t 2411 psid ( ) 8, c 4.5.2.f.1 B1348 psid ( } ", c 4.5.2.f.2 SIP A & B 4.5.2.h.1.a CCP A,B & C 3 339.0 gpm ( ) "< c 4.5.2.h.1.b CCP A,B & C 5560 gpm ( } ** c g 442.5 gpm [ ] 8, c 4.5.2.h.2.a S1P A&B 4.5.2.h.2.b StP A 5 670 gpm
- Reference 7 SIP B 5 650 gpm
- Reference 7 indicates that Stone and Webster established these values. NEU to verify with Stone and Webster, A brief discussion of referenced calculations as it applies to the current Technical Specification values follows:

[ [

[ minimum acceptance TAC curve at higher flows and no margin was available. [
i ) e,c. The results of this calculation are a mini flow surveillance criteria of 2 2338 psid at 50 gpm, and a corresponding analysis value (4.5.2.h.1.a) of g 339.0 gpm.
- c " Millstone Unit 3 ECCS Reanalysis" [ ] *< c
[
This calculation documented CHG/SI, HHSI and Residual Heat Removal System (RHRS) changes to the TAC 01 procedure and generated minimum ECCS flow rates. The
- CHG/SI and HHSI minimum and maximum branchline resistances were evaluated to provide the lirr.iting ECCS flowrates. [
] ** c. The results of this calculation are a CCP mini flow surveillance enteria of 2 2298 psid at 50 gpm which is an analysis value based on a corresponding 4.5.2.h.1.a flow of1310.5 gpm.ne HHSI flows from this calculation were revised in Calculation
[ ]* c summarized above.
Bases for the Revised Technical Specification limits The Millstone Unit 3 ECC5 Technical Specification ihnits have been revised based on Westinghouse ECCS calculations References 3 and 4 as follows:

The CCPs are limited to [ ] *, c gpm from the Refueling Water Storage Tank (RWST) if both RHR pumps are operating along with both CCPs and HHSI pumps. References 3 and 4 show that the rethrottled CHG/SI system flow is less than [ ] a, c gpm from the RWST with one CCP operating therefore adequate l NPSH is provided to the CCPs.

)*>c.The Technical Specification results of this calculation are a mini flow surveillance criteria of 2 5676 ft (24M psid) at 50 gpm based on TAC / analysis pump curve data and a corresponding analysis flow value (4.5.2.h.1.a) of1310.5 gpm. The results of this calculation are consistent with the data in Reference 5 letter.

References 3 and 4 evaluated the rethrottled system relative to Reference 5 data. Except for the all lines injecting ase for the CHC pumps, which has been evaluated by the appropriate safety analysis group through the Technical Specification change review process, there were no adverse flow deviations.
