BYPASS LEAKAGE PATH l

1. 3 A BYPASS LEAKAGE PATH is a potential path for leakage to escape from both L

the primary containment and annulus pressure boundary.

Only one type'of L

BYPASS LEAKAGE PATH is recognized:

a.

BYPASS LEAKAGE PATHS TO THE AUXILIARY BUILDING are those paths that would potentially allow leakage from the primary containment to circumvent the annulus secondary containment enclosure and escape L

known values of the parameter which the channel monitors.

The CHANNEL CALIBRA-TION shall ancompass the entire channel. including the sensor and alarm and/or trip furctions, and shall include the CHANNEL FUNCTIONAL TEST.

The CHANNEL CALIBRATION may be performed by any series of sequential, overlapping or total channel steps such that the entire channel is calibrated.
