DESCRI/ TION OF AMENDMENT REQUEST l The proposed amendment to the operating license for Dresden Station Unit 1 reflects the need to maintain a Possession-Only License through the l I

SAFSTOR and dismantlement period. 1 l 1 l

BASIS FOR NO SIGNIFICANT RAZARDS CONSIDERATION Commonwealth. Edison has performed an evaluation of the hazards  ;

consideration associated with the proposed License extension utilizing the criteria in 10CFR 50.92. Our evaluation is provided below and i i

specifically addresses.the three criteria of 10CFR 50.92(c) for the I license extension.

The proposed license extension does not involve a significant increase in the probability or consequence of an accident previously evaluated. The proposed license extension would allow for possession and maintenance, but not operation of Unit 1. The Final Hazards Smnmary Report, FHSR, addressed numerous design basis accidents. All these accidents-originated from an operating reactor. The license specifically prohibits operation of the reactor. Therefore, accidents such as loss-of-coolant, overpressurization, failure to scram, loss of reactor recirculation pumps, etc. are no longer of concern. The FHSR also briefly addressed off-site doses from gaseous and liquid. effluents. The non-operating status of the unit has reduced the production of such radioactive materials. Reduced production results in reduced probability of release of such material to the environment. Thus, extension of the operating license will not result in a significant increase in the probability or consequence of an accident previously evaluated.

The proposed license extension does not create the possibility of a new or different kind of accident from any accident previously evaluated.

The license specifically prohibits operation of the Unit i reactor.

Possessing and maintaining a reactor in a de-fueled condition will not create the possibility of a new or different kind of accident since this condition was achieved during each refueling outage experienced by Unit I while Unit I had an operating license.

The proposed extension does not involve a significant reduction in the margin of safety because the Technical Specifications contain adequate controls for prohibiting reactor operation, for maintaining spent fuel pool water level and for monitoring ated restricting radioactive effluents from Unit 1.

For the reasons stated above, Commonwealth Edison finds that the proposed amendment does not involve a significant hazards consideration based on the criteria of 10 CFR 50.92(c). We therefore request approval of the proposed license extension under the provisions of 10 CFR 50.91(a)(4).
