PSC will resolve the NRC's coments on the Technical Gpecification format, footnotes, action statements and other related aspects and incorporate these resolutions into the current overall schedule for the Technical Specification Upgra:fe Program' (Reference 3).

For the Fixed Feedwater Flow Low Parameter setpoint which the staff found unacceptable, PSC is in the process of re-evaluating the basis and analyses for the setpoint justification.

PSC will submit, under separate cover, our schedule for providing any additional information I

on this setpoint as soon as our re-evaluation is complete.

In the interim we will continue to use our current setpoint value of ~ 20%

which the staff recommends.

Should you have any questiens concerning this matter, please contact Mr. M.H. Holmes at (303) 480-6960.

l Very truly yours, Jq1Luwe x_.,
