Mr. Charles E. MacDonald, Chief Transportation Branch Gentlemen:

Subject:

Application for Revision of Compliance No. 5450, Docket 71-5450 The Westinghouse Electric Corporation hereby requests the revision of Certificate of Compliance No. 5450, Docket 71-5450, to include an RCC-4 type shipping package in the series of packages authorized by the certificate.' The RCC-4 package is described in the attach-ment. 'Its distinguishing characteristic is the length of the packaging, which is =24" longer than,the RCC-3 packaging.

. Westinghouse requests that the following changes be made to the existing. revision (6) of Certificate of Compliance No. 5450:

f 1)

Item' 5 (a) (1) should be changed to read; "Model Nos.: RCC, RCC-1, RCC-2, RCC-3, and RCC-4."

2)

, Item 5,(a) (3) should be revised to delete the word "and" after the word RCC-2.

The period after the word RCC-3 should be changed to a comma and add "and.1460E92, 1460E94, and 1460E96 for the RCC-4."

3)

Item 5 (a) (4) should be changed to read " Fuel rod container reinforced 13 gage steel box constructed in accordance with Westinghouse Electric Corporation Drawing No. C56J0055."

4)

Item 5 (b) (1) (ii) should be revised to include another column for 17 x 17 Zr clad:

Item 5 (b) (1) (iii) should be revised to include an additional column for Zr clad:

Rod Diameter (Nom), in 0.374 Fuel Length (Max), in 168 Maximum U-235 3.5 enrichment, w/o 6)

Item 5 (b) (2) (ii) should be revised to read "... not more than 80 kilograms..." instead of "... not more than 60 kilograms...".

Please note that previous transmittals indicated that the assem,i blies (12 ft., 17 x 17) were assumed to be of infinite length;

~ i.e., an axial buckling of zero was used.

Since the effective multiplcation factors for the various shipping container geometries for 17 x 17 fuel was calculated with zero axial leakage, the results previously transmitted may conservatively be applied to 14 feet, 17 x 17 (non optimized) fuel assemblies enriched with up to 3.5 w/o 235.

g The container internals and fuel cross section for the RCC-4 are identic'al'to the RCC-1 and RCC-2 packages.

The external shell will be at least as thick as on earlier designs.

The weight per unit length is approximately constant for 10, 12 and 14 foot fuel in the appropriate shipping container.

The crush configuration that follows the maximum credible accident (MCA) is therefore the same for the RCC-4 as for the earlier RCC-1 and RCC-3 designs.

The design will meet the requirements of 10 CFR 71.31 and 71.32.
