a.4.5.4 Acceptance Criteria

a. As used in this specification:

1) Imperfection means an exception to the dimensions, finish, or contour of a tube from that required by fabrication drawings or specificatima. Eddy-current testing indications below 20% of the nominal tube wall thickness, if detectable, may be considered as imperfections;

2) Degradation means a service-induced cracking, wastage, wear, or general corrosion occurring on either inside or outside of a tube;

,3) Decraded Tube means a tube containing imperfections greater than or equal to 20% of the nominal' wall thickness caused by degradation;

4)  % Deoradatice. means the percentage of the tube wall thickness affected or removed by degradation;

5) Defect means an imperfection of such severity that it exceeds the plugging limit. A tube containing a defect is defective;

6) Pluccino Limit means the imperfection depth at or beyond which the tube shall be removed from service and is equal to 40%

of the nominal tube wall thickness;

7) Unserviceable describes the condition of a tube if it leaks or contains a defect large enough to affect its structural integ-rity in the event of an Operating Basis Earthquake, a loss-of-coolant accident, er a steam line or feedwater line break as specified in Specification 4.4.5.3c., above;

8) Tube Insoection means an inspection of the steam generator tube from the point of entry (hot leg side) completely around the U-bend to the top support of the cold leg; or an inspection from the point of entry (Hot leg or Cold Leg Side) completely around the U-bend to the opposite tube end. .

5 SURVEILLANCE REQUIREMENTS (Continued) 19)- Yreservice Inspection means an inspection of the fu'11' length of

'each tube in each steam generator performed by eddy current techniques prior to service to establish a baseline condition of the tubing. This inspection shall be performed prior to

initial: POWER OPERATION.using the equipment and techniques expected to be.used during subsequent-insurvice inspections.

b. The steam generator shall; be determined OPERABLE after completingL the corresponding. actions (plug all tubes exceeding the plugging limit'and.all tubes containing through-wall cracks) required by -

Table 4.4-2.

. 4.4.5.5 Reports 7 a. Within 15 days'following the completion of- each inservice inspection of steam generator. tubes, the number of tubes plugged in each steam generator shall.be reported to the Commission in a Special Report pursuant to Specification 6.9.2;

b. The complete results.of the steam generator tube inservice inspection shall be submitted to the Cummission in a Special Report pursuant to Specification 6.9.2 within 12 months following the completion of the inspection. This Special Report shall include:

1) Number and extent of tubes inspected,.

2). Location and percent of walt-thickness penetration for each indicEtion of an inoperfection, and

3) 1dce.tffication nf tubes plugged.

c. Results cf ' steam generator tube inspections which fall iato Category I C-3 nhall be reported in a Special Report to the tonnission pursusnt to Specification 6.9.2 withtr 30 days and prios to resumption of plant nperatien. This report shall provide a description of investi-gatiu 5 ccnducted te determine cause of the tube degesdatiQn and cort ective measures taken to prevent recurrence.
