Dear Mr. Miller:

Clinton Power Station Unit 1 Docket No.

50-461 Attached are details related to the following item which was discussed with Nick Fioravante Auxiliary Systems Branch, during a meeting of November 30, 1981 to resolve issues for the Clinton SER:

ISSUES MSIV Leakage Control System The above item is considered by the NRC and IP to be closed for CPS Licensing purposes.

Sincerely, ON J.D. Geier Manager, Nuclear Station Engineering Attachments cc: J.H Williams, NRC Clinton Project Manager H.H.Livermore, NRC ilesident Inspector N. Fioravante, Auxiliary Systems Branch l 9i \\

Section 6.7 Main Steam Isolation Valve Leakage Control Sys.

The applicant should correct Section 6.7.2.3a of the FSAR and propose a MSIV leakage rate test frequency consistant with the Standard Technical Specifications.

Response

MSIV-LCS testing will be in accordance with NRC Standard Technical Specifications.

See attached copy of the draft CPS technical specifications.

W With one HSIV leakage control system subsystem inoperable, restore the M. y-inoperable subsystem to OPERABLE status within 30 days.

(Operation may then 1

continue if the secondary containment bypass lokage is within the limits of Specification 3.6.1.2.c when the MSIV leakage is included.

Otherwise,) (m9 be in at least HOT SHUTDOWN within the :

SURVEILLANCE REOUIREMENTS 4.5.1.4 Each MSIV leakage control system subsystem shall be demonstrated OPERABLE:

At least once per 31 days by verifying:

a.

Blower OPERABILITY by starting the blower from the control room and operating the blower for at least 15 minutes.

l 2.

Heater OPERABILITY by demonstrating electrical continuity of the *D heating element circuitry.

b.

During each COLD SHUTDOWN, if not performed within the previous 92 days, by cycling each motor operated valve through at least one completie cycle of full travel.

At least once per.18 months by performance of a functional test which c.

includes simulated actuation of the subsystem throughout its operating 1
