Techniques and procedures have been developed at the transuranium processing plant to produce quantities of special high-purity isotopes, e.g. /sup 227/Ac, /sup 242/Cm, /sup 250/Cf, /sup 251/Cf, and /sup 254/Cf by short-term irradiation of appropriate target materials in the high flux isotope reactor (HFIR). The general sequences of operations required to produce special isotopes includes (a) purification of the target isotope from other actinides, lanthanides, and cationic impurities, (b) fabrication of the target assembly; (c) irradiation in HFIR's hydraulic rabbit facility; (d) target dissolution; and (e) product isolation and purification. Usually, all of these steps must be scheduled carefully and coordinated to optimize the yield and enrichment of the product isotope. The operations associated with the various high-purity isotopes are similar and are illustrated by the procedures used to produce /sup 250/Cf.
