e. Lithium isotope separation technology. This subcategory includes classified technical information on the separation of lithium isotopes by using counter-current flows of lithium amalgam and aqueous lithium hydroxide solution in packed columns. Not included is information regarding plant design and operating conditions from which total production rates or design capacity of the lithium isotope separation plant (Colex) in Oak Ridge, Tennessee, can be inferred. In addition to the other requirements of this part, access permits for Restricted Data in this subcategory will be approved, provided the permittee:
1. Demonstrates that it is not a corporation or entity owned, controlled or dominated by an alien, a foreign corporation, or a foreign government, and
2. Agrees to insertion in his access permit of the terms and conditions:
(i) Set forth in paragraphs (a) and (b) of § 725.23 of this part;
(ii) Set forth in paragraph (c) of § 725.23 of this part, amended by deleting the phrase “category C-24, isotope separation,” and inserting in lieu thereof the phrase “subcategory C-44e, lithium isotope separation technology”;
(iii) Set forth in paragraph (d) of § 725.23 of this part, amended by:
(A) Deleting the phrases “production or enrichment of special nuclear material” and “separation of isotopes” wherever they appear, and inserting in lieu thereof the phrase “separation of isotopes of lithium”;
(B) Deleting the phrase “domestic commercial uranium enriching services are provided by,” and inserting in lieu thereof the phrase “domestic lithium isotope separation capacity becomes available to.”
This category does not include information which reveals or from which can be calculated actual or planned (as distinguished from design) capacities, production rates and unit costs for the plutonium production program.
C-65Plutonium Production. This category includes information on reactor, fuel element and separations technology which reveals or from which can be calculated actual or planned (as distinguished from design) capacities, production rates and unit costs for the Hanford and Savannah River production facilities.
