Director Office of Nuclear Reactor Regulation Nuclear Regulatory Commission Washington, DC 20555

Dear Sir / Madam:

Re: University of Florida Training Reactor (UFTR)

Facility License: R-56; Docket No. 50-83 Enclosed is an updated proposal intended to meet the requirements of 10 CFR 50.64(c)(2).

Except for scheduling, this proposal is essentially unchanged from that originally submitted with a cover letter dated March 26,1987 and later revised as to its schedule pursuant to a request from the NRC Project Manager Theodore Michaels dated April 17,1987. This revised schedule was submitted with a cover letter dated May 14, 1987. It is also essentially unchanged from the updated proposals submitted in March of subsequent years except for the revised schedule and the presence of substantive informadon on progress to date including the final fuel bundle design.

The updated written proposal outlines how the R-56 licensee intends to meet the requirements of 10 CFR 50.64 Paragraph (c)(2) to include certification that funding for conversion had been received through the Department of Energy for the first phase of the project and a tentative schedule for conversion based upon availability of replacement fuel acceptable to the Commission and upon consideration of the availability of additional funding, shipping casks, '

implementation of arrangements for the available financial support and allowing for commitments of reactor usage. The schedule had slipped significantly in previous years due to delays in work to qualify the SPERT fuel and due to delays in safety analysis as we awaited code implementation and availability of graduate students for the work. The delays in work with the SPERT fuel were most significant in 1988 and 1989 as the SPERT fuel had to be moved, under the SNM-1050 license, and then various license changes approved prior to initiation of the qualification work which was lengthy and subject to several equipment (X-ray machine) failures. The non-destmetive testing of the SPERT fuel was completed 9503310106 950327 PDR ADOCK 05000083 h v

Letter to Director, NRC Page 2 March 27,1995 i successfully by April,1989; however, shielding and other structural changes necessitated by use of the SPERT fuel resulted in a decision in August,1989 to utilize plate-type silicide fuel for the conversion. With this decision made, work was then expected to progress more rapidly as the code methodology for safety analyses was being implemented and tested in parallel.

Unfortunately, the decision by the graduate student performing this work to leave the university to pursue his degree elsewhere in August,1989 necessitated essentially restarting i

the safety analysis when a student began work on it for his thesis in early 1990. Although he spent a week at Argonne National Laboratory working with the RERTR group to receive training in the use of the codes, it still took time for the student to become proficient in the use of the codes. Unfortunately several flaws in the implemented codes used for the neutronics analysis also slowed progress though these were cleared up in early,1991.

1 In April,1991, a student project concluded the benchmarking neutronics analysis on the existing HEU core demonstrating acceptability of the static neutronics methodology to model the existing core. Similarly a thesis project concluded in May,1991 produced the static neutronics analysis for the proposed LEU core with the number of fuel plates per bundle now set at 14. DOE-supplied funding support of this work was extended beyond April 30,1991 but this was not accomplished until March,1992 resulting in some delays due to administrative problems. Nevertheless, the complementary basic thermal hydraulic analysis and other analysis work required to conclude the HEU to LEU safety analysis was undenaken and has been nearly completed as work had been underway in the 1993-1994 year to prepare the safety analysis report package required for the NRC. Delays have been involved since then because of the inability to get the existing grant support extended to allow project completion up to SAR submittal. The grant support was finally extended in late November,1994 but little work has been accomplished as the funding remaining in the grant is for support of a non-permanent employee (student) who has not been identified. In mid-March, DOE advised they will extend the grant with its remaining support past the current March 31,1995 ending date so we are in the process of getting the support funding category changed to allow completion of work through submittal of SAR changes. This change will require several months. However, DOE also advised in mid-March that additional funding for the next phase (Phase II) of the conversion will not be available in this year's DOE budget.

We have also been working closely with the Department of Energy in Idaho to assure fuel availability in a timely manner and to make decisions on utilization of the existing fuel boxes. The final design review on the fuel is in progress and questions about holddown devices have been cleared up by DOE. Only a very small piece of the neutronics analysis remains to be completed. After this work is completed, the entire package can be assembled for submission to NRC by October,1995 but with the project progressing as predicted in the attached updated proposal.

Letter to Director, NRC Page 3 March 27,1995 One final area has involved considerable time commitments during this past year. - This is the effort to renew the SNM-1050 spent fuel license. Since DOE cannot accept this fuel for return, we must follow through on assuring it meets storage licensing requirements. -

If further information is needed, please advise. Thank you for your consideration.

UNIVERSITY OF FLORIDA TRAINING REACTOR LICENSE NUMBER: R-56 UPDATED PROPOSAL SUBMiritu TO .

THE NUCLEAR REGULATORYCOMMISSION TO MEET 10 CFR 50.64 REQUIREMENTS FOR UPDATING SCHEDULING OF UFTR CONVERSION FROM HEU TO LEU FUEL Dr. William G. Vernetson Director of Nuclear Facilities March 27,1995 l

UNIVERSITY OF FLORIDA TRAINING REACTORFUEL CONVERSION FROM HIGH ENRICHED TO LOW ENRICHED URANIUM FUEL INTRODUCTION This proposal is submitted to the Nuclear Regulatory Commission to meet the requirement that the licensee for the University of Florida Training Reactor (UFTR), as a licensee of a non-power reactor authorized to possess and use high enriched uranium (HEU) fuel shall develop and submit a proposal to replace all HEU fuel possessed under the R-56 license with available low enriched uranium (LEU) fuel acceptable to the Nuclear Regulatory Commission on a schedule determined pursuant to 10 CFR 50.64 Paragraph (c)

(2). This proposal addresses the overall process of conversion from initial preparations following receipt of funding'to support conversion to final verification, testing, and summary reporting on the converted UFTR. Three primary phases have been identified for control i and administration of the overall process of conversion as follows:

I. Preparation for Conversion.

II. Conversion (assuming NRC order to convert).

III. Review and Verification of Conversion.  ;

1 1

Table I contains a listing of key activities involved in each phase of the conversion from l

receipt of funding for conversion from the Department of Energy (DOE) to final submittal ,

of summary reports to DOE and NRC on the conversion.

i 1

PIIASE I: PREPARATIONFOR CONVERSION Phase I commenced with receipt of funding for conversion from DOE to cover Phase I only. This funding was considered to be certified per the letter contained in Appendix I l of the 1987 proposal; this proposal was submitted to the Department of Energy and official 2

w ..  ;

1

• . J

. notic'e of receipt of funding was received with a letter dated November 12,1987. Because of errors in the contract description provided by DOE, the full approval for receipt of funding was delayed until receipt of the confirming letter dated December 21,1987. Copies of both letters as well as the 1987 certification letter are enclosed in Appendix I along with documentation showing the extension of the current DOE grant to support Phase I work which has been delayed beyond the original grant period.

Initial efforts in the process to convert the UFTR from use of high enriched to low enriched fuel (HEU-LEU) consisted of preliminary tests'and an evaluation to determine

/ ,

whether the SPERT-type fuel available to the R-56 licensee but currently under license SNM-1050 could be qualified for use in the UFTR. Visual and radiographic test results to date were positive in this regard. Unfortunately, equipment failures and the need to move ,

t the SPERT (SNM-1050) fuel storage facilityimpacted the schedule during the 1988 year so the radiographic tests were not completed until April,1989 along with relicensing the SPERT fuel storage facility. Overall, the results of the radiographic tests of the SPERT fuel.

were positive showing that the condition of the fuel was such that its integrity was assured.

i Phase I then continued with activities to justify a fuel selection, either SPERT or silicide, based upon results of prequalification testing of existing SPERT fuel and identifying any modifications in existing reactor systems necessitated by use of the new fuel.  :

Several previously unconsidered potential complications noted in late 1988 were investigated in 1989. This effort was directed to maintaining and/or improving the UFTR neutronics characteristics while minimizing the overall cost of UFTR conversion. The only-two fuels that have been considered are the existing SPERT UO2 , stainless steel clad fuel presently under the SNM-1050 license and the newly developed silicide fuel available through the RERTR program at Argonne National Laboratory.

c .

~.

The first choice had been to use the already existing SPERT fuel for which a number of neutronics and thermal-hydraulics analyses are in existence. This would be the cheaper fuel if acceptable since it is already manufactured. However, even after completion of the prequalification program for the qualification tests used to assure the SPERT fuel can meet UFTR requirements without compromising safety,it was necessary to assure this SPERT fuel could be used without requiring costly modifications which could outweigh the low initial cost of SPERT fuel (no manufacturing costs) and have impact on core neutronics per earlier analyses. The Department of Energy was receptive to this evaluation of the two fuels and work in this area progressed wellin 1989. Unfortunately, the complexity and cost of potential structural (the SPERT fuel loading would weigh about 2000 pounds versus the present 50 pound core loading), shielding, fuel arrangement and cooling system changes necessitated by use of the SPERT fuel resulted in a milestone decision in August,1989 not to utilize the SPERT fuel for conversion but rather to utilize the standard plate-type silicide fuel. The anticipated cooling system fuel arrangement and shielding changes potentially necessitated by use of the SPERT fuel were especially strong factors in the decision since space in the UFTR facility is already limited and the facility had been cited for two violations in this area in 1989.

In parallel with selection of the plate type silicide LEU fuel and identification of necessary reactor systems changes, safety analysis were being performed for the selected LEU fuel conversion and associated system changes. Implementation of the neutronics codes to be used was underway during 1989 and several codes had been implemented and run for test cases. Therefore, UFTR conversion calculations were progressing reasonably well until the loss in August,1989 of the graduate student performing the neutronics calculations as he decided to pursue his advanced degree at another university.

4

. Unfohunately, he left with much of his work inadequately undocumented. The unavailability of another qualified student committed to assume this responsibility resulted in further delays. Nevertheless, a student project in Fall,1989 resulted in some progress in assuring neutronics methodology would be adequate though many calculations had to be updated and repeated due to errors in and poor documentation of the previous work. It was hoped that this individual would remain on the project for his thesis work. This retention effort was successful and the neutronics analyses were able to move forward in 1990.

Several errors due to poor documentation necessitated restarting the safety analysis when the student began work on it in early 1990. Although he spent a period at Argonne National Laboratory working with the RERTR group to receive training in the use of the codes, it still required some time for the student to become proficient in use of the codes in-house. Unfortunately several formatting and other flaws in the implemented codes used for the neutronics analysis also slowed progress in 1990. These were cleared up as part of the work on assuring proper code methodology during 1990.

Early in 1991 a student thesis project had resulted in good progress in assuring the neutronics methodology to be adequate and the necessary " benchmark" modelling of the existing core was nearly complete. Only scoping calculations had been completed for the LEU core with the number of fuel plates per bundle not yet set when the 1991 proposal required by 10 CFR 50.64(c)(2) was submitted. It was expected that DOE-supplied funding support of this work would be extended beyond the April 30, 1991 end date per verbal communications so this work could be concluded along with basic thermal-hydraulic analyses to conclude the required HEU-to-LEU conversion safety analyses. Unfortunately this grant was not officially extended until March,1992. It was also expected that the individual working on this neutronics analysis would complete his thesis work by mid-1991. The 5

l i

, q i

~= " benchmark" static calculations on' the existing ~ UFTR HEU core were completed and an

-l internal' report generated in April,1991. The individual working on the neutronics analysis l completed his thesis workin May,1991 making his defense on May 10,1991 but continuing his work until May 23,1991. After the number of fuel plates per bundle was set at 14 from -

the neutronics analysis, thermal hydraulics analyses were begun in August,1991. "Ihese analyses had to be completed before the entire analysis package could be assembled for submission to NRC. A graduate assistant had nearly concluded working on the thermal hydraulics area as the 14 plate fuel bundle arrangement had been selected for the conversion in March,1992. The lack of official grant extension made the financial support of this effort more difficult but a draft report of this thermal hydraulics werk was produced in June,1992 with the final report now essentially completed during this past year.

i

?

. A no-cost extension of the Department of Energy Grant DE-FG05-88ER75387 entitled " Conversion of University of Florida Reactor to Iow Enriched uranium (LEU)" was submitted to Ms. Ann Rydalch via a letter dated April 25,1991 with a copy supplied to  :

i Keith Brown. The extension was agreed to be until April 30, 1992. Unfortunately, no i further information had been received on the no-cost extension until March,1992 making  !

1 some plans and efforts difficult to implement. In addition, time consuming efforts were also in progress with the Department of Energy representatives in Idaho to investigate the ,

possibility of replacing the UFTR core fuel boxes which make reloading and unloading the i core difficult and time consuming. DOE representatives even visited the UFTR facility and observed operations as well as reviewed drawings as several days were spent in discussions i

of how best to proceed in 1992. This unexpected work effort occupied much time and progressed slowlybut a decision not to change the fuel boxes was finally reached in summer, 1992. Similarly efforts to review fuel drawings and to evaluate the holddown/ spreader pin ,

from DOE at-the UFTR facility and ready to be reviewed. when the grant is officially L

extended. .!

- During the previous year, work to incorporate all the analysis completed to date into a single FSAR update to include the Technical Specifications progressed very slowly with  :

some kinetics calculations still remaining in the neutronics area. During the previous year' r it was expected that the . DOE. supplied funding support for this work would again be  ;

extended beyond April 30, 1993 with the DOE project manager checking on this per.a telephone request made in June,1993. 'A letter dated August 9,1993 requesting such an .

. extensien was submitted to DOE. In a letter dated November 5,1993, DOE indicated that the no-cost extension needed to be submitted to the Oak Ridge office; the resubmittal of j the extension request to the Oak Ridge Operations Office was accomplished via a letter dated December 15,1993. During January,1994, the Oak Ridge office indicated that the proper submission really is to the Idaho Operations Office; when informed of this, the l 1

project manager was to check, but the grant was not extended as needed until November, .

1994. This work was expected to be completed by June,1994. However, little work has -

been accomplished as the funding remaining in the grant is for support of a non-permanent employee (student) who has not been identified. In mid-March, DOE advised they will-extend the grant with its remaining support past the current March 31,1995 ending date so we are in the process of getting the support funding category changed to allow completion of work through submittal of SAR changes. This change will require several months.

However, DOE also advised in mid-March that additional funding for the next phase (Phase II) of the conversion will not be available in this year's DOE budget. The entire l

7

~ = -y

. package of results willthen be assembled as a Revision to the UFTR Safety Analysis Report by October,1995 with the project then expected to progress as indicated in the updated Table II.

I As indicated, previous delays have necessitated several extensions in the initial DOE grant which had been received as documented in Appendix I with another extension requested and verbally agreed to, to pick up from April,1993 as indicated above to assure continuous funding throughout the remainder of the conversion process with a new grant to be required for Phase II. In addition to neutronic and thermal-hydraulic analysis, shielding and effluent analyses will be documented to identify any changes in procedures (few expected), security plan, technical specifications or other license documents that must l

be considered as part of conversion. These should be minimal. This submittal will also contain documentation detailing the various tests and surveillances planned as part of the conversion. At this point a complete set oflicensing documents for the conversion willbe submitted along with a conversion application for review and approval. This result is now [

expected by October, 1995. Assuming resolution of all questions, this . submittal will conclude the Phase Ilicensee efforts. Phase I will then conclude with the issuance by the NRC of the specific Order to Convert.

PHASE H: CONVERSION (Assuming NRC Order to Convert)

Phase II (Conversion) will begin with receipt of the NRC Order directing the conversion and any necessary changes to the license, facility and/or procedures per 10 CFR 50.64(c)(3). This second phase was not yet funded by the existing DOE grant for which an extension has been requested and willinclude all final tests conducted with the HEU fuel to serve primarily as the basis for later comparison with similar tests with LEU fuel. Phase 8

1. Shutdown core decay for several weeks followed by core unloading and shipment i ofirradiated HEU fuel.

2. . Qualification of the selected LEU fuel (as applicable).

SUMMARY

CONCLUSIONS  ;

i As noted earlier, 'a relatively detailed list of the: various' elements that must be; .j i

' obtained, produced or otherwise generated as required throughout the three phases of the  !

UFTR conversion from HEU to LEU fuel is presented in Table L The current ' plan ' i

. 1 continues to be to generate as much of the required safety analysis and design workin-house i as possible. Only items such as silicide fuel (now the selected. fuel) would be designed and.-

manufa:tured outside the administrative control of the UFTR licensee. At this point, j without having identified all required changes, it is not possible to delineate . exactly what other external support may be needed. The neutrcales and thermal-hydraulics analyses are  !

all being conducted in-house which has necessitated some external support from the l RERTR program at Argonne National Laboratory to assure proper. code implementation - j Li at the University of Florida to carry out the required safety analysis. Work has progressed j l i slowly with delays due to SPERT fuel inspection delays, graduate. student changes and j i

inability to identify qualified graduate. students to work on the project for their thesis work

.h up until the previous two years when progress on the use of the neutronics methodology was l l

delayed by several code inconsistencies and lack of documentation which have now been i corrected. The effort to generate the submittal package is underway and is ' expected to  !

i progress rapidly during summer,1995 with submittal in October,1995.

The overall flow diagram for HEU to LEU conversion of the UFTR is presented in  ;

I Figure 1. Key stages in the three phases, as well as key input items at the various stages,  !

~,

, are indicated at each stage. Nevertheless, there is still some uncertainty in the exact plan of events in Phase II such as whether LEU fuel will be accepted on site prior to shipping HEU fuel off site. Another concern is the physical fit of the fuel in the fuel boxes which will necessitate some considerable experimental measurement and verification efforts after this year. These items are now under consideration.

Finally, Table II contains an updated tentative schedule (Revision 7) for the major milestone events in the UFTR conversion process commencing with the notification of receipt of funding effective in November,1987 and concluding with submittal of a final report to NRC and DOE summarizing the results of the conversion byJune,1996. It should be noted that this schedule is tentative and, as required by 10 CFR 50.64,willbe updated i

yearly. There has been considerable schedule slippage during the past few years. The schedule is also subject to variations caused by availability of replacement fuel or other l

items involved in required facility changes as well as variations in the level of DOE funding after the first two year period (now extended) for which funding has been received. Other areas which may impact the schedule are the availability of a shipping cask especially for l l

irraciated HEU fuel (we are currently using our HEU fuel at a rate of about 1.5MW-Days T l

energy generation per year so it will almost certainly require a fuel cask versus a 6M l container though this may depend on the cooling period) and fmal usage of the UFTR with HEU fuel to provide a basis for comparison of changes in operating characteristics or to 1

meet education, research and service commitments. Within these constraints and conditions, the schedule in Table II is one which the licensee is committed to meeting and which the licensee considers relatively realistic based upon expected resources. and recent progress with neutronics calculations.

Although much of the detail of the conversion process has depended upon the final 11

, selection of fuel types, this selection is now finalized; therefore, the information, especially the tentative schedule in Table II provided in this updated proposal, shows that the LEU conversion at the UFTR has progressed up until this past year with significant delays occurring during the year again due to delays in getting the extension to the DOE grant to document completion of the thermal hydraulics calculations and to work with the Department of Energy, EG&G Idaho on fuel review and checks for insertion into the core.

As previously indicated, we lost the individual working on the submittal package last year.

At this point, reactor staffincluding the Director are still planning to complete the package without graduate assistant support which has proven unreliable in supporting this project.

The key decisions remaining willinvolve identification and evaluation of system changes required by the conversion, especially concerning utilization of the. existing fuel boxes, shipment of used fuel and delivery of new fuel as well as development and implementation of a test program for both the HEU and LEU cores some of this uncertainty is also involved with the possibility of DOE replacement of UFTR fuel boxes. The schedule willlikely be most impacted, however, in the near future by the times required for completing and documenting the safety analysis in a submittal package and perhaps for manufacture of the LEU fuel. The schedule presented in Table IIis considered to be realistic and should be attainable now that the neutronics methodology has been proven acceptable, neutronics calculations are complete for both the HEU and LEU core and thermal hydraulics calculations are also complete except for several relatively minor documentation points. All analyses show the 14 plate LEU fuel bundle is acceptable for the conversion. As a result we should be able to conclude in a few additional months making the proposed schedule for first submittal realistic assuming DOE extension of their grant.
