Gentlemen:
The University of Michigan requests that the Ford Nuclear Reactor (FNR) license No. R-28 be amended to allow an increase in the total number of kilograms of contained uranium on-site from 16.1 to 25.
Discussion and Explanation As part of the low enrichment uranium (LEU) program, a total of 45 standard fuel elements, each containing 167 grams of urantum-235, and 10 control rod elements, each containing 83.5 grams of uranium-235, are to be delivered to the Ford Nuclear l
Reactor in early 1981 for a LEU whole core demonstration.
This total of 8.35 kilograms of uranium-235 added to the FNR's current licensed limit yields 24.45 kilograms.
Since the reactor will be operating under its normal schedule during arrival of the I
LEU fuel.and subsequent planning for the whole core demonstration, the LEU fuel will be an addition to the inventory of highly enriched' fuel on hand.
Argonne National Laboratory, sponsors of the LEU program, are purchasing the LEU fael from CERCA (Compagnie pour l' Etude et la Realisation de Combustibles Atomiques) in
' France and NUKEM (a manufacturing conglomerate) in Germany, Fuel element dimensions
[
and characteristics when manufactured by these companies are identical to those de-scribed in the SAFETY ANALYSIS, UTILIZATION OF LOW ENRICHMENT URANIUM (LEU) FUEL IN TIIE FORD NUCLEAR REACTOR, October,1979, which is under your review at the present time, l
cxcept the aluminum alloys used in the fuel core powder, fuel plate covers, and fuel element structure are French and German alloys.
TABLE 1 (attached) lists the chemical compositions of United States, French, and German aluminum alloys proposed - for LEU j
fuel elements.
Though each has chemical differences, all are of high quality suitable
(
for use in reactor fucis.
E The Union Carbide reactor' is licensed t( use CERCA fuel manufactured with the French j
alloys.. The General Electric Test Reactor is licensed to,use NUKEM fuel made with the German alloys.
In addition, both companies have extensive experience successfully supplying European reactors with plate fuel including OSIhIS (70 MW), Ilh R Petten (45 MW),
BR2 (80 MW), ORPIIEE (14 MW), and the German-French-British Reactor in Grenoble.

R-28 50-2' James R. Miller Page 2 Requested License Amendment Change paragraph 2.b. of License R-28 to read: Pursuant to the Act and Title 10, CFR, Chapter 1, Part 70, "Special Nuclear Material," to receive, possess.and use f
(1) 16.1 kilograms c # contained uranium-235 as fully enriched uranium
.for use in conneew cn with operetion of the reactor.
(2) 9.0 kilograms of contained uranium-235 in fuel enriched to less than.20% in uranium-235.for use in connection with operation of the reactor.
'e (3)
Up to five fission type neutron detectors which may contain up to a maximum total of 10 grams of uranium-235 as fully enriched uranium.
This matter has been reviewed and approved by our Reactor Safety Review Committee.
Sincerely, F
William Kerr
