2.0 Initial Conditions 2.1 The unit is critical.

~

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

.available.

2.2 The data from the previous two 1-PT-46.2 procedures are available.

3.0-Precautions and-Limitations 3.1 The following data must be collected and' trended according to the following surveillance intervals:

a) N-16 Radiation Monitor hours b) 1-RM-SV-121 (Air Ejector) - 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> i..

f) RCS isotopic samples - 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> 3.2 This procedure.is performed once-every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

However, portions of this procedure aust be completed 'in accordance with the above surveillance requirements, so the following steps must be performed during the following time intervals:

Step 4.1: 00:00 to 04:00 I

Step 4.2: 04:00 to 08:00 i

- Step 4.6: 20:00 to 24:00 3.3 The individual minor steps may be performed out of sequence, as long -as -all the major steps are performed within their required surveillance periods.

3.4

'If any of the leak rate determination methods identified in Step 3.1 are not available,-mark and initial the appropriate steps "N/A" and initiate a Work Request (ADM 16.5).'

Record the Work Request' number on she Critique Sheet. Immediately notify the Shift, Supervisor to review Standing Order Number 155 for any required a'etions.

3.5 Use Attachment 6.10 as guidance to estimate the RCS isotopic values.

3.6 If the power history is sufficiently unstabic to estimate the primary isotopics,-then request a RCS isotopic analysis.

- 3.7-If Attachments 6.7, 6.8 and 6.9 demonstrate conflicting trends, or if data'is questionable,-immediately notify the. Shift Supervisor p

l and contact Chemistry to perform a leak rate calculation (CAP-4.0).

l.

L 3.8 - If the' total primary-to-secondary leak rate demonstrates a 60L spd

~

increase between surveillance intervals, immediately notify the Shif t Supervisor to reduce power to less than or equal to 50% as soon as

possible, but within 90 minutes, and immediately reevaluate the leak rates using step 4.1.

1-PT-46.2 Page 4 of 29 00-00-00 3.9 Evaluate the trend in the leak rate to determine the time at which the individual leak rates will exceed 100 spd. If Chemistry can not perform CAP-4.0 before the trend would: indicate a 100 spd leak rate, initiate a Plant Shutdown and be in mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and initiate'l-AP-24.1.

3.10 If the total primary-to-secondary leak rate exceeds 300 gpd total leak rate, or 100 spd per steam generator, initiate a plant shutdown and be in mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and initiate 1-AP-24.1.

3.11 Condenser Air Ejector flow rate is measured once per eight hour shift by 1-LOG-6.C.

Unless leak rates are rapidly increasing, use this data to complete Attachments 6.1 through 6.6.

3.12 Samples /ccunt rates should be taken/ recorded at approximately the same time' to better ensure compatibility of leak rate compar1Lans.

3.13 The Condenser Air Ejector radiation monitor (1-RM-SV-121) "High" alarm limit shall be set to less than or equal to 20 gpd above the current leak rate.
