f UNIVERSITY OF MISSOURI AT COLUMBIA L

DOCKET NO. 50-186 1.

Please provide a safety analysis for your proposed change to Technical Specification 3.8.d concerning k,ff limits for fuel. storage.

2..

Please explain the safety significance of adding limits on volume % of P

UA1 Powder for the fuel meat in Technical Specification 4.1.b.

x f

P 3.

.It appears that all reference to uranium-aluminum alloy fuel is bei_ng.

removed from the Technical Specifications..Is this correct?

i 4.

Your proposed changes to Technical Specification 4.1.c removes the limit on the maximum uranium-235 (U-235) per fuel element and adds boron

~

l carbide to the fuel as a burnable poison. However, our evaluation l

focused on ELAF with a maximum loading of 17.70 grams U-235 and boron carbide in selected fuel plates.

Please suggest wording for Technical Specification 4.I.c.that addresses these limits based upon ELAF.
