ww 1-AP-24.2 Page 2 of 3 00-00-00 1.0 Purpose 1.1 This procedure provides the inoications of, probable causes for and the immediate and long term actions to be taken in the event of a small stesa generator tube Icak.
2.0 Indications 2.1 Steam Generator blowdown radiation monitors (RM-SS-122, RM-SS-123 or RM-SS-124) showing increasing activity or are in alarm.
2.2 Condenser air ejector radiation monitor (RM-SV-121) showing increasing activity or is in alarm.
2.3 Main Steam Header N-16 radiation monitor (01-MS-RI-193A) in alarm or recorder (01-MS-RP 193) shc,*ing increasing activity.
2.4 Radiation Monitor Recorder (RR-100) shows an increasing activity level for steam generator blevdown monitors or condenser air ejector outlet activity.
3.0 Probable Causes 3.1 Small hole in a steam generator tube.
4.0 Immediate Operstor Action 4.1 Notify Shif t Supervisor.

5.0 Long Term Operator Actions 5.1 Attempt to determine which steam generator is leaking.
5.2 Notify Chemistry and Health Physics departments for samples.
'5.3 Isolate blowdown on the affected steam generator, BUT leave the lineup to the sample system open.
'5.4 Perform a " Reactor Coolant System Leak Rate" as per 1-PT-52.2 to determine the leakage rate.
5.5 Determine the need to chift to auxiliary steam, from Unit 2, or auxiliary boilers as per Health Physics recommendations.
5.6 Determine the need to isolate steam from the affected steam generator to the steam driven aux. feedwater pump (1-FW-P-2).
5.7 JF, secondary coolant activity exceeds 10-5 Ci/ 1m, THEN place u
and Special Order Blue Tag the turbine building sump pumps in manual operation. Samples of the sumps must be collected AND analyzed-PRIOR'to release.
5.8 Request Chemistry to trend:the leakage on the affected SG on a daily basis {gt more frequently as required.
5.9 Refer to Standing Order #155 to ensure compliance with allowable primary to secondary leakage.
5.10 Resume steam generator blowdown of the affected steam generator e
I based on Health Physics and Chemistry Dept. recommendations.
5.11 Terminate this procedure.
