Director Standardization and advanced Reactors Division of Project Management U. S. Nuclear Regulatory Commission Washington, D.C. 20555 Docket #50-267

Subject:

Fort St. Vrain Fuel Surveillance Gentlemen:

i In correspondence dated June 20, 1978, reference number P-78103, PSC described a Post Irradiation Surveillance (PIE) Program, that is presently planned for the reference fuel installed in the reactor to be funded through the Department of Energy (DOE).

In describing the on-site examination, " gamma scanning to determine ,

fission product distribution and core power distribution" was mistakenly included. This examination is to be included on a selective basis as indicated in the description of the destructive fuel PIE.

We request that you therefore remove gamma scanning from the description of the on-site examination.

It should also be noted that the on-site examination described in corres-pondence P-78103 would be carried out during the first six refuelings only. There are no plans for including additional characterized fuel elements in the reactor for examination beyond the sixth refueling.

Very truly yours, J.' K. Fuller Vice President Engineering and Planning JKF:11 7 E l f 1 pr $ g 1 2.
