Dear Mr. O'Reilly:
In the Corrective Action section of Significant Deficiency Report SD 413-414/82-26, dated January 17, 1983, it was stated that the defective piston skirts would be repaired and/or replaced by June 1, 1983.
It was originally planned that the work on the Unit 1 and Unit 2 diesels would be done concurrently; however, the Unit 1 diesels were finished first. The work on the Unit 2 diesels is now scheduled to be completed by August 1, 1983.
