SUBJECT:

Transmittal of Nondestructive Fuel and Reflector Examination Reports GA-A16829, 906505, 906577

Dear Mr. Collins:

In order to keep you apprised of the results of examinations to date on the fuel elements with cracked webs, PSC is transmitting 40 copies '1 of each of the following reports:

1) GA-A16829, " Nondestructive Examination of 54 Fuel and Reflector Elements from Fort St. Vrain Core Segment 2",

October 1982.

2) GA report 906505, " Nondestructive Examination of FSV Fuel Element 1-2415", May 17, 1982.
3) GA report 906577, " Visual Examination Results of Segment 2 FSV Fuel Elements 1-2415, 1-0172, 2-2693, 1-018 and 5-0801",

October 7, 1982.

These reports convey the belief that the cracks in the fuel block graphite webbing do not intersect fuel holes. However, upon destructive examination of block 1-2415 at GA Technologies Inc., the crack path was found to partially intersect a fuel hole. The report i on this DOE-funded destructive examination will be transmitted to NRC as soon as it is available.

If PSC can be of further assistance, or if you have any questions regarding this matter, please let us know.

Very truly yours, YMwL ]
