Any tube(s) which give indication at 100 KHZ will be reorobed using 400 KHZ.

2.

Hot leg tube gauging Hill be conducted on all three steam generators utilizing three different sized eddy current probes

(,540 in 610 in.,

and

.650 in. diameters).

The unshaded areas on the attached tube map identify the tubes to be probed.

3.

Cold leg tube gauging will be conducted on all three steam generators utilizing two different sized eddy current probes

(.540 in.,

and

,610 in,).

The blocked area on the attached tube map indicates the extent of the cold leg gauging, 4.

Handhol,e inspections using TV and/or photograohs will be used to inspect the flow slots and determine the extent of hourglassing on the 81 tube support plates in Steam Gene-rators A, B, and C.
