PADUCAH REQUEST FOR APPROVAL OF EXCLUSION FROM CRITICALITY ACCIDENT l ALARM SYSTEM DETECTION FOR CYLINDER STORAGE YARD (TAC NO. L32098) l

Dear Mr. Toelle:

l By letter dated November 17,1998, the U. S. Nuclear Regulatory Commission (NRC) granted USEC an l exclusion from the requirements contained in 10 CFR 76.89 for the C-745-U Cylinder Storage Yard l provided the following controls were in place to preclude maloperation:

j (1) The storage yard will only be used to store UF cylinders that contain toll normal material, heels from toll normal material, or tails material, all less than 1 wt%8 5U; and (2) USEC will control the C-745-U cylinder handling and storage operation through the use of training, plant procedures, and surveillances.

As one part of the implementing controls for item 2 above, the NRC inadvertently required the yard to be identified by fissile control area markings. However, since such markings are only used for identification of fissile materials greater than 1 wt%23sU, the use of these signs for the C-745-U Cylinder Storage Yard would be inconsistent and confusing. Therefore, by receipt of this letter, the November 17,1998, letter is hereby amended to eliminate reference to fissile control area markings.

Should you have any questions or concerns, please contact Merri Hom of my staff at (301) 415-8126.

Sincerely, I
