SUBJECT:
SAFETY EVALUATION REPORT: STORAGE OF URANIUM COMPOUNDS IN SEA-LAND CONTAINERS BACKGROUND By letter dated January 21,1999, SPC requested an amendment to Materials License SNM-1227 to include, as an authorized activity, the storage of moderated uranium oxide in sea-land containers. The NRC authorized this activity on May 11,1999, in Amendment 16. By letter dated May 27,1999, SPC requested another amendment to change the authorized activity from the storage of uranium oxide to the storage of uranium compounds.
DISCUSSION The NRC approved the operation of two new uran.om recovery facilities; the Modular Extraction Recovery Facility (MERF) and the Liquie Uranium Recovery / Solids Processing Facility (LUR),
Amendments 10 arid 12 respectively. The product of MERF is uranium oxide, but the LUR produces a uranium compound (sodium ammonium uranium (IV) fluoride), in Amendment 16, the NRC authorized the products from these facilities to be stored in sea-land containers while awaiting further processing. SPC had characterized the products as moderated uranium compounds, but requested the license be changed to allow the storage of uranium oxide, After the amendment was granted, SPC noticed this discrepancy and requested a change to the authorized activity from the storage of uranium oxide, to the storage of uranium compounds.
CRITICAL ITY SAFETY In the amendment request letter dated January 21,1999, SPC provided data on numeroes KENO V.a calculations for both normal and abnormal scenarios using optimally moderated uranium oxide powder saturated with H 0. In each instance, the staff found the models 2
conservatively bourded the worst case abnormal condition and covered the credible single-failure mechanisms. Since uranium oxide is the most reactive element of the applicable uranium compounds, the uranium oxide analysis bounds the reactivity of the uranium compounds. Therefore, SPC has adequately demonstrated that the storage of moderated uranium compounds in sea-land containers is safe.

CATEGORICAL EXCLUSION
- From the information SPC provided in the January 21 and May 27,1999, letters, the staff determined that the proposed change does not adversely affect public health and safety of the environment and the amendment should be categorically excluded from the requirements to prepare a specific environmental assessment. Therefore, in accordance with 10 CFR 51.22(c)(11), neither an environmental assessment nor an environment impact statement is warranted.
CONCLUSlQN The staff has determined that the proposed revision to store moderated uranium compounds in sea-land containers does not adversely affect the health and safety of the workers, public, or the environment and the amendment to Materials License SNM-1227 should be approved.
Region IV inspection staff has no objection to this proposed amendment.
