't Denver, Colorado 80225 IN REPlJ ltEV!:H M October 11, 1978 U. S. Nuclear Regulatory Commission Division of Reactor Licensing Washington, D.C. 20545 Attention:

Charles Trammel Docket No. 50-274 Reactor License R-ll3 By this letter, we request the following change to our license.

Paragraph 2.B states: " Pursuant to the Act and Title 10, Chapter 1, CFR, Part 70, "Special Nuclear Material", to receive, possess and use up to 4 kilograms of uranium-235 for use in connection with operation of the reactor."

We request that this paragraph be changed to read:

Pursuant to the Act and Title 10, Chapter 1, CFR, Part 70, "Special Nuclear Material," to receive, possess and use up to 5_ kilograms of uranium-235 for use in connection with operation of the reactor".

This change is requested because we are approaching the time when we will need to acquire additional fuel in order to maintain adequate excess reactivity for our experimental programs. We are seeking to obtain surplus fuel elements from a facility that has converted to FLIP fuel, rather than purchasing one element at a time.

The present limit of 4 kilograms is not adequate if we are able to obtain a number of elements at one time.

Paragraph D.2 of our Technical Specifications states: "The excess reactivity above cold critical, without xenon, shall not exceed 4.9%

delta K/K with experiments in place".

No change is requested in this section. The change will apply only to the possession limit.

=

There are 122 fuel positions in our core, and we now possess 105 elements.

Adequate storage is available either in the reactor tank or in dry storage wells.
