Dear Sir:

My letter dated April 29, 1977 advised you that a probability study of a failure of the Reactor Coolant System in the annular region between the reactor vessel and the cavity shield vall in order to address concerns relative to the Oconee Nuclear Station Reactor Vessel Support System would be submitted in July, 1977. Due to certain refinements and increases in the scope of the study, the report has not been submitted. It is expected that the report will be available for submission in the near future.

Ver d truly yours,/
