Subject:
McGuire Nuclear Station Dockets Nos.: 50-369 and 50-370 Selected Licensee Commitment Manual (SLC)
Reference:
10CFR50.4 and 50.71 Gentlemen:
The SLC Manual is Chapter 16 of the McGuire FSAR. This manual contains commitments and other station issues that warrant control, but are not appropriate for Technical Specifications.
Attached are seven copies of the latest revision to the McGuire Selected Licensee Commitments (SLC) Manual. This revision rearranges and enhances Tables 16.11-? and 16.11-3, providing
{
more precise definitions and controls for the Discharge Canal Minin m Flow Interlock.
For questions regarding this revision, please contact Dwin Cald.a at (7(M) 875-4328.
Very truly yours,

ACTION STATEMENTS ACTION 1 -
With the number of channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, effluent releases may continue for up to 14 days provided that i
prior to initiating a release:
a.
At least two independent samples are analyzed in accor-dance with SLC 16.11-1, and
[
r b.
At least two technically qualified members of the facility staff independently verify the discharge l
line valving:
1)
The manual portion of the computer input for the release rate' calculations performed on the computer, or t
2)
The entire release rate calculations if such calcula-tions are performed manually.
I Otherwise, suspend release of radioactive effluents via this pathway.

TAHLE NOTATION i
(1) The ANALOG CHANNEL OPERATIONAL TEST shall also demonstrate that automatic isolation of this pathway and control room alarm annunciation occur if any of the following conditions exists:
l Instrument indicates measured levels above the a.
Al' arm / Trip Setpoint; i
b.
Circuit failure (alarm only); and, Instrument indicates a downscale failure c.
I (alarm only).
~.
l (2) The ANALOG CHANNEL OPERATIONAL TEST shall also demonstrate that control room alarm annunciation occurs if any of the following conditions exists:
i Instrument indicates measured levels above the Alarm a.
Setpoint; b.
Circuit failure; l
l i
Instrument indicutts a downscale failure; and, c.
(3) The initial CHANNEL CALIBRATION shall be performed using one or more of the reference standards certified by the National
}
Bureau of Standards (NBS) or using standards that have been obt.ained from suppliers that participate in measurement assurance activities with NBS.
These stan-dards shall permit calibrating the system over its intended range of energy and measurement range.
For subsequent CHANNEL CALIBRATION, calibration shall be used. sources that have been related to the initial (4) CHANNEL CHECK shall consist of verifying indication of flow.
CHANNEL CHECK shall be made at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> during periods of release.
