Dscket 1(o, 50-10 m 23 E Co::::2onwealth Edison Company Change No. 10 72 West Adams Street Chicago 90, Illinois Attention:
Mr. D. Robert Bower Gentlemen:
Co::zaonwealth Edison, by letter dated December 24, 1964, has requested authorization to load up to 104 Type III-F fuel assemblies in the Dresden reactor. By addendum dated March 2,1965, Commonwealth submitted supple-mentary information.
This change, designated Proposed Change No. 10, has been considered pursuant to the provisions of Section 50.59, 10 CFR 50.
On the basis of the infor-mation submitted in support thereof, we have concluded that Change No. 10 does not present significant hazards considerations not described or implicit in the hazards summary report and that there is reasonable assurance 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:
E Maximum core diameter (circumscribed circle) 129 in.
Maximum active fuel length - cold 112 in.
Maximum number of fuel assemblies by types:
Type I 263 Type 11 102 Type III 192 Type III-F (standard) 88 4; q Type III-F (removable experimental segmented poison rod) 6 y
Type III-F (powder) 10 p
Type PF-10 and PF-ll (one each) 2 Type SA-1 1
Maximum total number of fuel assemblies 488 8000050
Commonwealth Edison Company RAR 2 3 ESS The fuel assemblies may be located in any position of the reactor, provided that fuel assemblies Type PF-10 and PF-11 are each separated from the other by at least four Type I, Type II, Type III, or Type III-F fuel assemblies.
The reactor may be operated at any power up to and including rated power with any configuration of the various types of fuel assemblies installed, provided the maximum number and location are within the limits specified above.
2.
Section B.3, page 2, second paragraph, as follows:
The nominal fuel pellet density averaged over a fuel segment is 94.3% of theoretical for all fuel assemblies except ten Type III-F assemblies which contain vibratory compacted UO2 Powder with a nominal density of 85% of theoretical.
3.
The tabulation in Section D.3, page 12, is amended to read as follows:
Fuel Type I 350,000 Fuel Type II 410,000 Fuel Type III 360,000 Fuel Type III-F 360,000 Fuel Type PF-10 and PF-11 510,000 Fuel Type SA-1 425,000 4.
Table II (revised February 19, 1964) should be replaced by Table II (revised November 13, 1964) as set forth in Commonwealth Edison's application dated December 24, 1964.
Sincerely yours, Original sigad by us.
