FALL 89 OUTAGE STEAM GENERATOR TUBE INSPECTION SCOPE (TAC NO. 69344)
By letter dated August 30, 1989, Consumers Power Company committed to provide the NRC with the final eddy current inspection scope for the October 1989 steam generator inspection.
As discussed during the meeting of September 12, 1989, with NRC staff, Consumers Power Company will inspect all of the tubes recommend-ed by MPR Associates in their support plate stress evaluation report (MPR-1125, Palisades Steam Generator Proposed Eddy Current Inspection Plan, May 1989).
The scope consists of inspecting 1006 tubes in A steam generator hot leg and 783 tubes in B steam generator hot leg.
All of these tubes will be inspected with the 8 x 1 probe.
A subset of these tubes which are located near previous leakers will be inspected with the MPRC at support plates 3 or 13.
The MRPC will be used to inspect 239 tubes in A hot leg and 94 tubes in B hot leg.
The.8 x 1 probe is qualified for the detection of circumferential cracks.
It is not, however, qualified to size IGA or wastage type defects.
During the inspection, a large number of "noncrack" indications are expected to be identified with the 8 x 1 probe in regions of IGA or wastage.
In order to ensure these indications do not represent true degradation growth or exceed the plugging criteria, Consumers Power Company will inspect 10% of the tubes which contain "noncrack" indications (or a minimum of 100 tubes) with a bobbin probe.
Any indications which exceed Palisades plugging criteria will be plugged.
The results of t~ese inspections will be used to determine if an expansion in scope is necessary during this or subsequent inspections.
