Mr. Herbert N. Berkow, Director License R-95 Docket 50-193 Gentlemen:

This letter is transmitted to meet the requirements of the HEU-LEU conversion rule.

The Rhode Island Atomic Energy Commission submitted a funding proposal to the Department of Energy on May 2, 1986 for the conversion of the Rhode Island Nuclear Science Center reactor to low enriched uranium fuel As required by the Department of Energy, the submission was based on the use of a standardized LEU fuel plate containing considerably more U235 (225 grams vs.

124 grams) and thinner (0.050 inches vs. 0.060 inches) than the fuel plate currently in use in the Rhode Island reactor.

The contract with the Department of Energy for the conversion study became effective on August 15, 1986.

The use of the standardized plate in the Rhode Island reactor will create conditions which will require compensating adjustment.

While the Department of Energy grant contains some funding for potential hardware solutions to these conditions is is primarily a study grant intended to find solutions to the conditions.

Scoping studies in cooperation with the RERTR group at Argonne are in progress with the goal of designing a satisfactory core arrangement.

These studies are expected to continue for the remainder of 1987 during which the data required for the application to the Nuclear Regulatory Commisison for authorization to convert will be generated.

After receiving the Nuclear Regulatory Commission order to

convert, the schedule is as follows:

All times are measured from the date of receipt of the Nuclear Regulatory Commission conversion order.

1.

Completion of plans and schedules.

2 months 2.

Installation of new hardware.

6 months 3.

Removal of HEU and replacement by LEU 7 months (assuming prompt delivery of LEU fuel elements).

4.

Completion of LEU initial tests of operational parameters with LEU.

8 months 5.

Reports to NRC summarizing new operating conditions and comparing with SAR predictions.

10 months 6.

Completion of shipments of HEU to reprocessing.

12 months During this period of study and implementation, the Rhode Island reactor will continue to operate using HEU as long as the implementation schedule permits.

Shipments of spent HEU fuel elements to reprocessing will continue.

It is therefore not expected that changes in the physical security programs will be required We will be pleased to provide more information if necessary.
