Dear Mr. Rusche:

In our February 8, 1977 letter, we informed you that we would provide a report of the complete results of our findings concerning the inspection of the broken control rod cluster assembly R-43.

The NRC Staff's Report to the ACRS dated December 14, 1976 requested that we submit a report of our findings within 60 days following the startup of Unit l.

With this letter we are transmitting three copies of the inspection report on the damaged RCC assembly.-entitled "Inservice Inspection Report of Damaged RCC Assembly at Donald C. Cook Unit 1 Nuclear plant."

This report provides the complete results of the visual examination of the damaged.

RCC Assembly R-43 from core location E-3.

Very truly yours, Sworn and subscribed to before me this 21st day of April, 1977 in,
