~,

a) ' A seismic occurrence greater than the operating basis I earthquake. )

b) A loss of coolant accident which causes significant deviations in ,

temperature or pressure which affect the integrity of the steam generator tubes, or requires actuation of the engineered

safeguards.

j c) A major steam lin- or rnajor feedwater line break.

D. Acceptance Criteria:

1. As used in this Specification:

^

a) -Imperfection means an exception to the dimensions, finish or

.- contour of a tube from that required by fabrication drawings or

. specifications. Eddy-current testing indications below 20% of

. the nominal tube wall thickness, if detectable, may be considered as imperfections.

b) Degradation means a service-induced cracking, wastage, wear 4

. or general corrosion occurring on either inside or outside of a tube, c) Degraded Tube means a tube containing imperfections R 20%

of the nominal wall thickness caused by degradation.

d)  % Degradation means the percentage of the tube wall thickness af fected or removed by degradation.

e) Defect means an imperfection of such severity that it exceeds the plugging limit. A tube containing a defect is defective, f) Plugging Limit means the imperfection depth at or beyond which the tube shall be removed from s:rvice because, it may become unserviceable prior to the next inspection and is equal to 50% of the nominal tube wall thickness.

g) Unserviceable describes the condition of a tube if it leaks or contains a defect large enough to af fect its structural integrity in the event of a Operating Basis Earthquake, a loss-ci coolant accident, or a steam line or feedwater line break as specified in Specification 4.10.1.C.3.

h) 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.

! 2. The Steam Generator may be returned to service after completing i the corresponding actions (plug a!! tubes exceeding the plugging limit l

and all tubes containing through wall cracks) required by Table 4.10.1-2, with the exception of plugging the tube in Row 37, Column 73 in Steam Generator 2 for Cycle 14.
