Dear Administrative Judges:
Reference is made to my letters to the Licensing Board dated June 17, 1988 and June 23, 1988, respectively. Attached to the latter letter was a letter dated June 21, 1988 from the NRC Staff to the Applicant requesting additional information.
Applicant on July 20, 1988, responded to Staff's request.
A copy of that response is attached for your information.
The Staff has not yet reviewed the response in question.
Sincerely, W
NNG Bernard M. Bordenick Counsel for NRC Staff

Mr. Hugh L.
Thompson, Jr.
6A-4 NMSS Docket Materials Gentlemen:
In response to Mr.
A.
Thomas Clark Jr.'s letter dated June 21,
- 1988, requesting additional information on enrichment of naturally occurring radioisotopes we advise as follows:
1.
For carbon-14 enrichment the highest concentration would be in dimethylzinc feedstock material.
Approximately 25% of this compound is carbon.
If it is assumed that carbon-14 is present with a specific activity level of 5 picoeuries per gram anu 4Kg are enric,ged to 100% the resulting activity would be 5X10 C1, an amount 200 times lower than one microcurie.
Clearly, carbon-14 enrichment is totally inconsequential.
A five picocurie per gram concentration corresponds to the highest levels found naturally,
- however, the alkyd feedstocks used for production are all petroleum-derived and will have spec.tfic activity orders of magnitudo lower than 5 picocuries/ gram.
2.
For tellurium-123 AlchemIE will be enriching approximately 60 grams to about 50%.
With a specific i
activity level of 0.2 X 10 Ci/Kg, 60 grams,pf this product would have an activity of 6 X 10 C1, an amount 167 time lower than one microcurie.
- Clearly, te11urium-123 enrichment is of no consequence.
The assumed 60 gram amount of product is excessive with respect to the inventory on site at any given moment.

Nuclear Regulatory Commission July 20, 1988 Page 2 3.
For ygadmium-113, the specific act1vity is 340 X 10 C1/Kg.
If it is assumed that all of the enriched product, about 120 grams, is cadmium-113, then the activity would be 40.8 picoeuries, an amount 25,000 times lower than one microcurie.
- Clearly, cadmium-113 enrichment is totally inconsequential.
Again, the assumed product amount of 120 grams of 100%
cadmium-113 is far greater than any inventory there will on-site at any given moment.
We hope these calculations have now removed any concern whatsoever with respect to the possible consequences of enriching any of these isotopes.
Sincerely, HEMIE ;INC.
