q In accordance with the licensee's application for amendment dated

{

April 11, 1977, the amendment w^uld modify the operating limits in the i

Technical Specifications to permit operation of the facility for fuel j

cycle 11 with Exxon Nuclear Company uranium 235 fuel assemblies, the i

amendment.would also incorporate associated Technical Specification j

Basis for Decision By letter of April 11, 1977, Commonwealth Edison Company (CE) requested authorization to operate with a new reload of fuel in Dresden 1.

The reload would be the first in Dresden 1 to be fabricated by Exxon but is similar to the previous reload fuel fabricated by Gulf United Nuclear.

Dresden 1 is presently being operated under an exemption to 10CFR50.46 issued August 21, 1975.

The exemption was granted from the requirements of and underlying 10CFR50.46 with respect to the design and diversity of emergency systems or the diversity of emergency power sources, but not from the specific performance requirements of 50.46.

The exemption was for the purpose of providing time to install a new ECCS system and expires December 31,'1977.

The exemption was granted based on preliminary evaluation by CE dated November 1,1974 and a fully detailed evaluation by CE dated July 31, 1975.

ihe exemption was issued based on a preliminary evaluation of the July 31, 1975 submittal by the staff.

The July 31, 1975, submittal was prenoticed in August 1975 and is still under review by NRC.

CE will submit an ECCS analysis for operation with the reload by June 15, 1977, along with any change in limits related to ECCS analysis which may be 7'

necessary.

It is unlikely that staff evaluation of the acceptability

~

of the model for Dresden 1 would be completed prior to the end of the refueling outage (about August 1,1977).

Therefore any approval of continued operation may have to be given within the authorization of 4

the August 21, 1975 exemption or a revised exemption.

An additional consideration which was factored into the August 21, 1975, exemption was that Dresden 1 was expected to be shutdown for six months in 1977 to perform reactor decontamination. That outage has been deferred l

until 1978, and with the exception of the refueling outage, CE prefers to

{

operate Dresden 1 for the remainder of 1977.

}

r Because of the uncertainties at this time about the effects of the reload j'

fuel on transient ar ' accident analyses and the relatively short time t

until the schedule (

• the outage, we suggest the requested authorization f.

3 to operate with the re'oad and the ECCS considerations involved with the f

reload be prenoticed.

[

I It is also our understanding that CE may request an additional exemption from 10CFR50.46 to provide them additional time to complete installation of the new ECCS system and may' request authorization to continue operation under an exemption through December 31, 1978.

However, CE requ,ts that i

operation with the reload and extension of the exemption be considered as l

separable issues by the staff.
