. Docket.50-2 License R-28 United States Nuclear Regulatory Commission Harold Denton, Director Division of Reactor Licensing Washington, D.C. 20555 Gentlemen:

The University of Michigan requests that Ford Nuclear Reactor Technical Specifications, page 9, section 3.1, specification (5) be changed as follows:

(5) The reactor shall be subcritical by at least 0.025 delta K/K during fuel loading changes.

A revised page 9 is enclosed for incorparation in our Technical Specifications.

In our license renewal request, originated on November 30, 1984, the shutdown margin relative to the cold, xenon free critical condition with all three shim safety rods inserted was changed from 0.03 delta K/K to 0.025 delta K/K (page 9, section 3.1, specification (1)) . The minimum subcritical reactivity for fuel movement is the minimum shutdown margin with all rods inserted. It was an oversight on our part that we did not request a concurrent change in specification (5) reactivity to 0.025 delta K/K.
