Re: Catawba Nuclear Station, Unit 2 SE Docket No. 50-414 g
Special Nuclear Material License Application u
Dear Mr. Davis:
M In addition to my letter of June 19, 1985, which was in response to the June 7, 1985 letter from Mr. Kishore Kodali, of your staff, we have the following additional comment:
In the Draft SER and proposed License on pages 11 and 21 (and License Condition 16b) there is a proposed restriction of 12 inches on the minimum edge to edge distance between assemblies in the shipping containers. The actual distance between the assemblies in the containers is approximately 2 inches. The approved Westinghouse shipping containers (Certificate of Compliance No. 5450) employ a poison spacer material which is between the fuel assemblies and will preclude inadvertent criticality. We propose deleting the minimum edge to edge spacing requirement for the shipping container array from the
]
SER and the License.
If there are any questions regarding this information, please contact Mr. Roger W. Quellette at (704)373-7530.
Very truly yours, A'l yW g

OPC's application specifies that no more than two fuel assemblies shall be out of their shipping containers or storage racks at one time.
l Calculations have indicated that two assem%11es could be made critical at optimum conditions of water moderation and reflection; however, one assembly, separated from another assembly by >12 inches of spacing cannot be made critical under any conditions. Therefore, the staff recommends the 3
following license condition limiting the number of fuel assemblies out of storage and the minimum distance from each other and from all other fuel:
Condition 16a. No more than two fuel assemblies shall be out of approved shipping containers or fuel assembly storage racks at any one-time.
- b. The minimum edge-to edge distance between the'two fuel assemblies,.... _,-,. 3 __.............,,and the storage A
rack arrays shall be 12 inches.
