-c,Pm It is respectfully requested that Special Nuclecr Material License No.
SNM 1050 (due to expire April 30, 1988 by License Amendment No. 9 dated Novem-ber 17, 1987) be amended in tho interim to allow use of a different storage location for the fuel and nondestructive check of welds on the stored pins.
The University of Florida Safety Review Subcommittee (SRS) for the UFSA Fa-cility covered by this license reviewed the status and conditions of the SNM-1050 license on January 28, 1988 and concluded that all safety requirements are met; it also directed that, at this time, plans to refurbish and operate the assembly for suberitical experiments be termirated. The remainder of this submittal consists of an update on the present facility status along with the two amendment requests and information supporting the amendment requests.
To update our license extension da ted Septertber 25, 1987, the present status of the UFSA facility covered by SNM-1050 is as follows:
1 The fuel is stored in a safe configuration in the Nuclear Research Field Building, as specified in our letter of July 15,1980 - a room adjacent to the Facility room.
2.
The facility has an NRC approved Physical Security Plan. The protec-tion provided by this plan and associated systems exceeds the re-guirements established in 10 CFR 73 for Materials of Low Strategic Signi fica nce. NRC Security Inspections have found no security prob-j lems with the Facility.
3.
As reported in 1985, a fire alarm system was installed ta provide enhanced automatic fire detection for the f uel storage and facility a rea. This system has been operational sinceJpril 10, 1985. A fail-ure of a smoke detector outside the storage area revealed the need to replace the existing smoke detectors, along with the monitor sta-tion to prevent further failures. This work was completed in Oc-tober,1987 and the system has functioned well since that time with no f ur ther failures.

As reported in a letter dated July 19, 1984, the facility had been partially dismantled and inspected. No structural or other safety-related defects were found. Parts of the control instrumentation would require repair or replacement. As of the SRS decision on Jan-uary 28, 1988, the remainder of the Facility room and the adjacent control panel and instrumentation is to be cleared out and assured to be suitable for unrestricted use. The Facility room (Room 5 on attached diagram) will then be prepared for fuel storage. The Fa-cility room itself will be assured to be suitable for unrestricted use though the room will remain a restricted room in expectation of approval to move the fuel to this room.
5.
The fuel storage area is properly mair'sined, including required r"rveillance activities. This Facility :ss reintained an unblemished balety record.
l 6.
A Quality Assurance Program plan with a cover 19tter dated September 2,1987 was submitted to NRC NMSS to address shipping up to 1200 of l
the fuel pias held under the SNM-1050 license to a secure experimen-tal facility under the Department of Energy at the Oak Ridge Na-tional Laboratory. Subsequently a resubmittal was required with a cover letter dated September 17, 1987. Program approval dated Novem-ber 5,1987 haa been received so this shipment is expected to occur before the middle of March to reduce substantially the SNM-1050 in-ventory from the present 5400 pins.
7.
In response to the NRC requirement (10 CFR 50.64) to convert the University of Florida Training Reactor (UPTR R-56 license) from high enriched to low enriched uranium fuel, a grant has recently been re-ceived from the Department of Energy to include qualifying some of the SPERT fuel for this conversion. We plan to examine, qualify, and (if accepted) use approximately 500 of these fuel pins (SNM-1050) to fuel the converted UPTR (R-56 license) with as msny as 100 addi-tional pins qualified for refueling purposes. This qualification will involve performing x-ray analysis on sufficient SPERT fuel pins to assure the integrity of welds including thickness for any UPTR fuel loa ding.
The SM4-1050 license amendment request consists of two parts to allow fuel movement to an adjacent room and non-destruct 4ve x-ray analysis. Af ter these activities are completed, we will seek a storage only license for the remain-der of the fuel.
l First ktendment Request 1
It is respectfully requested that permission be granted to move the fuel from Room 3 (present location per the 1980 letter) to adjacent Roem 5
{
(presently the facility room) for long term storage with Room 3 returned i
to unrestricted use. The room locations are labeled on the attached J
figure.

l Suppe rcing Information for First Amendment First, the proposs.d new fuel storage room is the-room used for the SPERT pulsing m<periments; as a result it is a much better shielded room, bet-ter suited to storage of the SPERT fuel under -the SNM-1050 license based upon the decision not to relicense a suberitical assambly. The attached floor plan illustrates this point.
Second, the fuel' will continue to be stored in a configuratiori identical to that used currently. New support racks vill be installed but the eme baskets will be used for the storage in the same geometry as now exists.
l l
Third, the fuel will be moved to the adjacent room by handling the bas-kets one at a time following strict radiation esfety procedures and pre-cautions and the same methods of movement will be as for moving fuel into the present storage room.
Second Amendment Request It is respectfully requested that approval be granted to perform nonde-structive testing (x-ray analysis) to verify the welds on up to 1500 of.
the SPERT fuel pins to provide a qualified source of low enriched' fuel for use in the HEU to LEU conversion of the University of Florida Train-ing Reactor (R-56 license). This non-destructive examination is to be performed on no more than 20 SPERT pins removed from the storage room at any one time in containers used originally to deliver the fuel to the Facility. This testing will be performed within Building #554 housing the UFSA storage Facility.
Supporting Information for Second Amendment First, radiation safety procedures and precautions will be strictly fol-lowed for all fuol handling with a special procedure written and approved by the SRS for performing the x-ray analysis. By limiting the removal of SPERT pins to 20 or less at any one time from the Facility, criticality safety will present no concern.
The University of Florida Safety Review Subcommittee for the UFSA Facili-(
ty covered by this license reviewed these amendment requests and the status and conditions of the Facility on Febraary 2, 1988 and has concluded that the l
safety requirements are fully met and that these additional license anadments will assure safe storage of the UPSA fuel in the Facility room (Room 5) and that the necessary NOT checks are made on SPERT fuel planned. to be used at the UPTR on the (R-56) license. We expect to submit a complete license renet:al application package for storage only of the renaining fuel held under the SNM-1050 license follcwing the standard format guide and prior to the license ter-mination on April 30, 1980.
