MOHAWK 300 ERIE BOULEVARD WEST SYRACUSE. N. Y. 13202 July 21, 1975 Mr. Karl R. Goller, Assistant Director Operating Reactors Division of Reactor Licensing United States Nuclear Regulatory Commission Washington, D. C. 20555 Re: Nine Mile. Point Unit 1

.Docket No. 50-220

Dear Mr. Goller:

The attached refueling information for Nine Mile Point Unit 1 is in response to your June 18, 1975 letter. Our present plans provide for plant shutdown on September 13, 1975 and start-up, following the refueling, on November 9, 1975.

The reload license amendment submittal will be provided by August 15, 1975 in accordance with the requirements of Enclosure 1 of your letter . We regret that this does not meet your requested 90 day lead-time. A'eavy licensing workload at our fuel supplier is the reason for the delay.

Sincerely, NIAGARA MOHAWK POWER CORPORATION

Refuel in Information Re uest

1. Name of Facility: Nine Nile Point Unit 1

2. Scheduled date for next refueling shutdown: September 13, 1975

3. Scheduled date for restart following refueling: November 9; 1975

4. Will refueling or resumption of operation thereafter require a technical specification change or other license amendment?: Yes There will be minor changes to Minimun Critical Power Ratio (MCPR} and possible changes to Rod Block Limits. The MCPR changes will arise from cycle dependent analyses of the most limiting MCPR transient. The possible changes to the Rod Block Limits will be based on cycle dependent analyses of the Rod Withdrawal Error transient.

5. Scheduled date(s) for submitting proposed licensing action and supporting information: August 15, 1975.

6. Important licensing considerations associated with refueling, e.g., new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures:

A cycle dependent analysis may require review of a Control Rod Drop accident which is outside the generic boundary approach.
