Initials l 1.0 Purpose .

To determine the N-16 Radiation Monitor "First" and "Second* alars setpoints, based on primary-to-secondary leakage concerns.

2.0 Initial Conditions NOTE: If this is an initial startup, then previous pts may not be available.

2.1 The trend of the N-16 Radiation Monitor from 1-PT-46.2 is available.

NOTE: If this is an initial startup, or a restart following a steam generator tube plugging outage, the initial leak' rate is assumed to be 0 spd.

2.2 The S/G 1eak rate da a from 1-PT-46.2 is available.

3.0 Precautions and Limitations 3.1 This procedure must be performed prior to entering Mode 1.

3.2 For an initial startup, or a plant startup following a S/G tube plugging outsge, the previous S/G 1eak rate is assumed to be 0 spd.

3.3 To recalculate the N-16 Radiation Monitor "Fi st" and "Second" alara setpoints, use the most recent leak rate calculations based,on the N-16 Monitor. Several leak rate results may be averaged to better ascertain the primary-to-secondary leak rate.

4.0 Instructions 4.1- Record the most recent primary-to-secondary leak rate data (based on the N-16 Monitor) from 1-PT-46.2 on Attachment 6.1. If this is a startup af ter a S/G tube inspection outage, record 0 gpd total l 1eakage on Attachment 6.1. l i

l

1-PT-46.15 Fage 3 of 3 00-00-00 4.2 Calculate the new "First" alarm setpoint for the N-16 Monitor using the equation at the bottos of Attachment 6.1.

4.3 Calculate the new "Second" alarm setpoint for the N-16 Monitor using the equation at the bottom of Attachment 6.1.

4.4 Immediately notify the Shif t Supervisor of the new alars setpoint.

4.5 Complete Attachment 6.2 and forward a copy to the Instrument Dept.

Supervisor.

4.6 Update the Radiation Monitor Setpoint Document in the Control Room to reflect the new setpoints.

4.7 Verify that the new setpoint has been implemented.

4.8 Post an Operator Aid (ADH-19.27) next to the N-16 Monitor stating both the "First" and "Second" alarm setpoints.

5.0 Acceptance Criteria 9

5.1 The new setpoint has been implemented and an Operator Aid has been posted.

6.0 Attachments 6.1 N-16 Alarm Setpoint Calculations 6.2 Memo to change the alarm setpoints for the N-16 Monitor.
