4.7 If the setpoint for a radiation detector alarm and/or trip is found to be higher than required, notify Shift Supervisor and take one of the following actions immediately'.

1) The setpoint shall be immediately corrected without declaring the channel inoperable; or
2) Declare the channel inoperable.

4.8 The individual performing the independent verification shall be a person knowledgeable in the appropriate system involved, normally an Auxiliary Operator or Licensees Operator (active or inactive).

PT-17. 4: 3 4.8.1 The initial realignment steps may be performed at various points throughout the procedure, however, the Independent Verification Check shall be performed upon completion of testing each individual train prior to proceeding to any other train.

5.0 PRECAUTIONS

5.1 Observe normal company safety practices.

5.2 Any deviations from stated limits in this procedure should be noted under comments and a WR/TR initiated when applicable.

5.3 Prior to opening Ammonia or Chlorine bottle, verify regulators are back-seated and bottles piped to detectors.

5' Care should be taken when handling Ammonia ( 60 ppm) and Chlorine bottles ( 3.0 ppm) since these are toxic substances.

6.0 INSTRUCTIONS

NQTE 1: Sections not to be performed may be marked N/A if not applicable.

NOTE 2: Testing of radiation detectors may cause a spike on one of the LED readouts of the detectors. This is indicated by an illegible reading. The LED must be reset by momentarily interrupting power to that detector (turn power switch inside drawer to "OFF" position, then return to "ON" ).

NOTE 3: During the performance of this test, R-36, 37 or 38 may go into alarm due to system transient caused by testing. If this occurs, ensure the applicable channel is less than the alarm/warning setpoint, reset by depressing the applicable warning/alarm pushbutton, and reset control room ventilation if necessary.

NOTE 4: 'ny time monthly surveillance is performed, total charcoal filter fan run time must be a minimum of 15 minutes.
