Director of Nuclear Reactor Regulation U S Nuclear Regulatory Commission Washington, DC 20555 MONTICELID NUCLEAR GENERATING PLANT Docket No. 50-263 License No. DPR-22 Supplement No. I to License Amendment Request Dated March 21, 1978 on March 21, 1978. Northern States Power Company requested a License Amendment to authorize the use of a new fuel type and allow the application of a special analytical technique for the Monticello In particular, the Staf f was requested to include the applica-core.

tion of General Electric retrofit fuel in the Monticello reactor when performing a generic review of Topical Report NEDO-24011, " Licensing Topical Report, General Electric Boiling Water Reactor, Generic Reload Fuel Application", da t ed May, 1977.

The Staff safety evalua-tion on this Topical Report was subsequently issued on May 12, 1978.

Cal cula tions for the reload core were in progress when we filed our March 21 Licens e Ame ndme nt Request and certain specific information was identified to be supplied later.

The application of retrofit fuel also involved minor editorial changes to clie technical specifica-tions as well as newly. calculated technical specification limits based on the analytical techniques presented in the referenced topical report. The partial drilled model was not used for the ECCS analysis of the reload core as we originally proposed in our March 21 Amendment Reques t.

The new fuel type was analyzed more conservatively using the currently approved methods.

ECCS limits for fuel types currently in use will remain in effect.

It is therefore not necessa ry at this time to make some of the changes proposed in our March 21 License Amendment Request.

However, we continue to request that you approve the use of the partial drilled tnodel for Monticello for future use.

1 For your convenience, we have prepared this supplement to our initial License Amendment Request as an independent package incorporating the additional information and deleting that which is not applicable at this time, so as to 'ully replace the March 21, 1978 submittal.

We request that our September 30, 1977 License Ame nd me nt Request (Revised MAPLHGR Limits) be reviewed and approved along with the Supplemental document.

Since the same pages are subject to change under two amendment requests, it would cause confusion to issue one without the other.

We see no technical reason for delaying issuance of an amendment in response to the September 30 request; we impicmen-ted these changes ab ou t a year ago, based on our agreement at that time.

A notice for opporcunity for public hearing was issued on November 1, 19 77, with no response to our knowledge.

The mechanics of the changes are as follows:

1.

License Change - Make the change to the Provisional Operating License as discussed in Exhibit A of our September 30, 1977 License Amendment Request.

2.

Reasons for Technical Specifica tion Changes and Safe ty Evaluations These can be found in Exhibit B of our September 30, 19 77 License Amendment Request.

3.

Technical Specificatf on Page Revisions - Revised Technical Specification pages are attached as Exh ib i t B to this Supplement No. I to License Amendment Request Dated March 21, 1978.

The pages are in the form we request them to be is sued ; that is, all the September 30, 1977 proposed changes have been incorpo ra ted along wi th the pr es en tly requested changes.

At tached are forty copies of Exhibits A, B and C.

Exhibit A describes the proposed changes along with reasons for the change. Exhibit B is a set of Technical Specification pages incorporating the proposed ch ange s.

Exhibit C is a saf ety evaluation supporting the changes.

We ask that this request be reviewed and approved prior to our Fall r efueling outage which is present2 y scheduled to commence on October 1,19 78.
