Subject:
Amendment of License SNM-928, Docker*070-92S Increased Possession Limit for U-23
Dear Sir:
By this letter and its attachments, the Kerr-McGee Corporation files amendment application No.
24 for authorization to possess no more than 6,000 kilograms of U-235 at any one time.
Additional business opportunities during 1971,.which primarily involve the storage of low enriched UF 6 for customers, show the need for increasing our maximum U-235 possession limit from 3,000 kgs to 6,000 kgs.
Approval of this amendment by April 20, 1971 is urgently re-quested, and will enable us to provide this service required by our customers on a timely basis.

AMENDMENT APPLICATION NO.
24 TO LICENSE SNM-928, DOCKET 70-925 INTRODUCTION This application for license amendment requests our U-235 possession limit be increased from 3,000 kgs to 6,000 kgs, and describes a new storage area for storing 30 inch cylinders containing UF 6 at a U-235 enrichment not exceeding 5%.
A.
Packages To Be Stored Packages to be stored will be the OR-30 cylinder as described in our license amendment No.
71-15, dated January 15, 1971.
B.
Storage Area and Cylinder Arrangement The storage area is shown on the attached drawing NPD-107-808.
The cylinders are to be stored only one high and in a horizontal position.
The drawing shows the arrangement.
C.
Nuclear Safety Evaluation Under optimum conditions of interspersed moderation, as shown by Figure 3 of K-1686, the k. is 0.83 for 5% U-235 enriched UF 6 within the-0.4 inch steel jacket.
This is more than adequate to account for calculational uncertainties.
