TURKEY POINT UNIT NO. 4 STEAM GENERATOR INSPECTION PROGRAM PLANNED FOR APRIL, 1979

l. Eddy Current testing of U-bends is planned as follows:

a) Steam Generator A, rows 2-5, columns 1-92; unplugged tubes will be tested at. 100 KHZ using beaded flex 0.540 probe.

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

2. Hot leg tube gauging will 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 hot leg gauging pattern map identify the tubes to be probed.

3. Cold leg tube guaging 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 cold leg gauging pattern map indicates the extent of the cold leg gauging.

4. Wrapper to shell annulus measurements will be made on Steam Generator B.

5. Handhole inspections using TV and/or 'photographs will be used to inspect the flow slots and determine the extent of hour-glassing on, the gl tube support plates in Steam, Generators A, B, and C.

6. A Reg. Guide 1.83 inspection will be i

performed.

7. Preventive plugging based upon the inspection results.

NOTE: A visual inspection (miniature TV Camera system) of the, reactor vessel lower internals is planned during this outage. This inspection will attempt to locate and retrieve a loose object believed to be in the vessel per past indications by the MIMS (Metal Impact Monitoring System).
