x REACTOR COOLANT SYSTEM SURVEILLANCE REQUIREMENTS (Continued) 4.4.5.4 Acceptance Criteria a.

As used in this specification:

1)

Imperfection means an exception to the dimensions, finish or contour of a tube fror that requirea by fabrication drawings or specifications.

Eddy-current testing indications below 20% of the nominal tube wall thickness, if detectable, may be consid-ered as imperfections; 2)

Cegradation means a service-induced cracking, wastage, wear or general corrosion occurring on either inside or outside of a tube; 3)

Degraded Tube means a tube containing imperfections greater than or equal to RO% of the nominal wall thickness caused by degradation; 4)

% degradation 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)

Plugging 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.

This definition does not apply to the area of the tubesheet region below the F* distance pro-vided the tube is not degraded (i.e., no indications of crack-ing) within the F* distance.

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, or a steam line or feedwater line break as specified in 4.4.5.3c, above; 8)

Tube Inspection 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; and McGUIRE - UNITS 1 and 2 3/4 4-14 Amendment No. 89 (Unit 1)

Amendment No. 70 (Unit 2)

r

.s.

REACTOR COOLANT SYSTEM SURVEILLANCE REQUIREMENTS (Continued) 9)

Preservice Inspection means an inspection of the full length of each tube in each steam generator performed by eddy current techniques prior to service to establish a basel1ne condition of the tubing.

This inspection shall be performed after the field hydrostatic test and prior to initial POWER OPERATION using the equipment and techniques expected to be used during subsequent inservice inspections.

10)

F* Distance is the distance into the tubesheet from the top face of the tubesheet or the top of the last hardroll, whichever is lower (further into the tubesheet) that has been conservatively chosen to be 2 inches.

11)

F* TUBE is a tube with degradation equal to or greater than 40%,

below the F* distance and not degraded (i.e., no indications of cracking) in the F* distance, b.

The steam generator shall be determined OPERABLE after completing 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 a.

Within 15 days following t'1e 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 Commission 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 wall-thickness penetration for each indication of an imperfection, and 3)

Identification of tubes plugged, c.

The results of inspections of F* tubes shall be reported to the Commission in a report, prior to the restart of the unit following l

the inspection.

This report shall include:

1)

Identification of F* tubes, and 2) location and size of the degradation.
