Chemical Processing Technology Quarterly Progress Report, October-December 1961

Description: The ICPP processed Al fuel, prtncipally of the MTR-ETR type, durtng this quarter. Newly designed and installed processing equipment exhibited excellent operating performance. This included direct-air-pulsed extraction, stripping and scrub columns, and a cascade-controlled continuous evaporator in first cycle product concentration service. Aqueous zirconium fuel processing studies continued with the objective of adapting the hydrofluoric acid process to continuous dissolution-complexing to incre… more

SOME OBSERVATIONS REGARDING RARE-EARTH LACTATES

Description: Lactates of all the rare earths except lanthanum, cerium, and praseodymium were prepared and studied. In the case of lanthanum, cerium, and praseodymium the laciates are apparently so soluble that they cannot be crystallized directly from aqueous solution. Products obtained by addition of anhydrous ethanol to sirupy solutions of the iight-rare-earth lactates were not well characterized and were deliquescent. Neodymium lactate trinydrate was prepared only by the addition of alcohol to a sirupy s… more

Fever--A One-Dimensional Few-Group Depletion Program for Reactor Analysis

Description: The one-dimensional difiusion-theory depletion program FEVER, written in FORTRAN-II for a 32,000-word computer is described. The code allows for the representation of self-shielded burnable poisons and provides methods for automatically adjusting control poisons in various regions of the reactor according to some specified sequence. No intermediate tape manipulation is required during the calculations, since all program and data storage are contained in the fast memory of the computer. Informat… more

Chemical Processing Technology Quarterly Progress Report, July-September 1962

Description: Aqueous zirconium fuel processing studies, directed at adapting the hydrofluoric acid process to continuous dissolution-complexing in order to increase the capacity of the ICPP process, resulted in two successful approaches to the complexing-feed adjustment step. Continuous in-line adjustment (conversion of uranium(IV) to uranium(VI) necessary for extraction) was accomplished in one minute or less at approximately 90 deg C; surges of dissolver product from the operating dissolver up to 1.9 time… more

WATER REQUIREMENTS FOR A RADIOCHEMICAL PROCESSING PLANT

Description: A survey of the water requirements is presented for a hypothetical plant to process all the fuel from a 15,000Mwe nuclear economy. For each processing plant, specific requirements must be based on a detailed water survey which includes water quality, process requirements, and in-plant conservation plans. These considerations are discussed and the quantitative requirements are listed. (J.R.D.)
