L' We have reviewed your submittal dated January 13,1975 (Propocod change 1
No. 120) in which you requested authorization of changes to Yankee-Rowe b
Technical Specifications relating to the set point limits for the " Low e,
l L Main Coolant Flow-Reactor Scram." Specifically, you propose to change the limit presently specified in terms of percent of normal flow to the more k
direct values of amperes to the main coolant pump motors which are more e
a;ipropriate for the existing coolant flow protection system using current transformors as loss-of-flow sensors.
We find that we nood additional information that will demonstrate that the h
proposed ampere set points will initiate a reactor scram at no less than 60% of normal main coolant flow in cach loop, as presently required in the Ik Technical Specifications, g'
Ni In order to maintain our review schedule, we need a response to thic request j$
by February 20, 1975.
The additional information should be submitted in M
the usuni manner as a supplement to your Proposed Chango No. 120.
