20555 Attnt Mr. Thomas E. Murley Ret University of Virginia's 2 MW,,3 UVAR reactor, Facility License R-66, Docket No. 50-62, LEU Fuel Conversion Schedule.

Dear Sir We were recently informed by EG&G's Idaho office (via a telephone communication) that, due to budgetary constraints, LEU fuel elements for the UVAR reactor will not be manufactured before September or October of 1991.

We have sufficient HEU fuel elements available to us to permit uninterrupted operations until that time, so the delay will not have a severe impact.

In November 1989, the University of Virginia submitted to the NRC an application to convert the UVAR reactor to LEU fuel.

The submittal included a revised SAR and also a conversion schedule.

To meet the requirements of 10 CFR 50.64 (c)(2), we would like to point out that the conversion schedule must be adjusted forward to reflect the above information.

Availability of DOE conversion funds September 86 EG&G Fuel Element Drawing Approval by U.Va.

November 89 Submittal to the NRC of UVAR SAR by Virginia with application to convert to LEU Fuel November 89 Expected Pitting of dummy LEU element (s) in U VAR May 91 Expected Notification of UVAR LEU fuel availability October 91 Receipt of NRC's " Order to Convert" A

Completion of HEU Fuel shipping plans and scheduling A+1 Completion of all HEU fuel shipments from site A+2 Expected UVAR reactor downtime 1 mo.

Receipt of LEU fuel for a complete UVAR core A+2 Loading of LEU fuel in UVAR core A+2 Completion of initial LEU fuel operating parameter tests A+3 Report to NRC containing summary of new UVAR reactor operational conditions, comparisons with SAR predictions, A+12 and license / tech spec conditions A

Date of NRC order to convert, expected to coincide approximately

with the date of LEU fuel availability.

If the milestones indicated in this schedule can't be met, despite best efforts, the conversion of the UVAR will be delayed accordingly.

HEU spent-fuel shipping date is dependent on cask availability.
