The ORNL RaLa plant as built in 1945 was designed to produce 400-1000 Curies of Barium 140 from slugs irradiated in the ORNL pile. From 1948 to the present time the plant has processed Handford-irradiated slugs which have a higher Barium content. Within the last year the plant has been modified to use an ion-exchage purification process to improve substantially the purity of the product. The present design capacity of the ORNL RaLa plant, as modified, is 10,000 Curies; but by using both the production and the standby facilities (the ion-exchange equipment is installed in duplicate) and by pushing the capacity to the utmost, 30,000 Curies can possibly be produced and shipped to Los Alamos in one product carrier. The current run, scheduled to begin Sunday, 12 August, and to finish Saturday, 17 August, 1951, will produce 15,000 Curies. This plant will produce RaLa until the Idaho plant has been completed. Report talks of capacity requirements as requested by Los Alamos, MTR-RaLa schedule for pilot plant and final plant construction, and justification for the MTR Rala pilot plant at ORNL. Also discussed is availability of supplementary services at ORNL.
