%h reasurer Gentlemen:
enrnnnwealth Edison Company has requested, by letter dated August 5,1963, authorization to load up to 200 Type III fuel assemblies into the core of the Dresden reactor at its forthcoming refueling.
This request, designated Proposed Change No. 4, was considered pursuant to the provisions of Section 50.59, 10 CFR 50 On the basis of the informa-tion submitted in support thereof, it was concluded that Change No. 4 does not present significant hazards considerations not described or implicit in the hazards sumanary report and that there is reasonable assursace that the health and safety of the public will not be endangered. A related hazards analysis is attached.
In view of the foregoing, the technical specifications to License No.
DPR-2 are hereby amended as set forth below.
1.
Section B.2, page 1, in its entirety, as follows:
Nuclear Core-Maximum Core Diameter (circumscribed circle) 129 in.
Maxiz::um active fuel length - cold 112 in.
Maxir:um number of fuel assemblies by types Type I 352 Type II 107 Tp e III 200 Type PF-8 through PF-12 (one each) 5 Maximum total number of fuel assemblies 488
Ihe various fuel assemblies may be located in any position of the reactor, provided overall core sy==ctry is preserved and provided that fuel assemblies Type PF-8 through 12 are each separated from any other such assembly by at 1 cast four Type I, Type 11, or Type II f u e l a n s

- 2. Section B.3, page 2, second paragraph, as follows:
The cinimum fuel pellet density averaged over a fuel segment is 94% of theoretical for all fuel assemblies except PF-8 anc' PF-9 which have fuel densities 907. of theoretical.
- 3. The tabulation in Section D.3, page.12, is amended to read as follows:
Fuel Type I 320,000 Fuel Type II 410,000 Fuel Type III 330,000 Eur.1 Type PF-8 and PF-9 470,000 Fuel Type PF-10 through PF.12 510,000 6
