- ' - JUN 211988 REQUEST FOR ADDITIONAL INFORMATION FROM ALL CHEMICAL ISOTOPE ENRICHMENT, INC.

FOR FACILITY-1 CPDF AND FACILITY-2 OLIVER SPRINGS DOCKETS 50-603 AND 50-604 RE: Letter, dated June 9',1988, from John H. Smelser, Jr. 'to the Nuclea;-

Regulatory Comission, Attention: Mr. Hugh L. Thompson, Jr., on the subject of concerns of the Attorney General of the State of Tennessee.

In the reference letter an attachment is provided which lists elements for which naturally occurring radioisotopes occur. The list is incomplete in that several naturally occurring isotopes which undergo double beta transitions are not included.' However, half-lives of these rore events are on the order of 10'O years and they may be safely neglected. Information is available, nevertheless, on the isotopic abundance of carbon-14 which is about 5 picocuries per gram of carbon

• at the earth's surface. Carbon in petroleum, which has decayed nyer many half-lives, will have considerably fewer atoms of carbon-14.

Since AlChemIE intends to use several kinds of organic chemicals as a potential carrier in its separation process, an analysis should be provided to show the extent to which carbon-14 could be enriched in the centrifuge machines.

In add! tion, for the naturally occurring radioisotopes shown on the table attached to the refsrence letter, AlChemIE should demonstrate the extent to which the process could enrich each isotope. For example, since the abundance ratio of tellurium-122 is 2.92 times that of tellurium-123 (with a small quantity of tellurium-120 added), the theoretical maximum atom fraction which could be produced should not exceed 0.38.

Please provide the infonnation described above as an an,endment to your environmental report.

• See, for example, Eisenbud, M. , Environmental Radioactivity, Academic Press, 1973, pp.187-8, and NCRP Report No. 81, "Carbon-14 in the Environment,"
