Letter, G03-82-831, dated August 20, 1982, Mr. R. S . Leddick to Mr. D. M. Sternberg, same subject.
Ebasco, in conjunction with Combustion Engineering (CE), was directe8 by the Supply System to assure an evaluation of the safe-end indica-tions (associated with the subject deficiency) was performed per 10CFR50.55(e). The referenced letter reported that this evaluation was not complete; however, upon completion, the results would be forwarded to your office by October 22, 1982. To date, the evaluation has not been completed. It is anticipated that the results will be l
provided to your office by January 14, 1983.
The status of repair actions taken is as follows:
o  CE has submitted an ASME Section XI repair plan documenting the rework required per,the disposition of Oe original NCR.
e  The repair plan was approved by Oa 5 opiy System and the work commenced on September 13,1%!
o Grinding operations revealed edditional indications that were not indicated on the RT film. CE elected to remove the indica-tions rather than evaluate the relevancy of the indications.
e Final PT of the excavation areas was accepted by CE QA Representa-tives and the Supply System on October 13, 1982.
