Simmons, J.W. ed.

Studies were continued on the laberatory evaluation of Canadian gravity concentrate, processing of Th-containing U concentrates, extraction of U in a HNO/ sub 3/--TBP--UNH system, corrosion rates of stainless steel in 70% HNO/sub 3/, denitration process, corrosion resistance of chrome-plated drum dryer to raffinate solutions, UO/sub 2/F/sub 2/ reduction process, process studies in the UO/sub 3/ to UF/sub 4/ process, effects of reduction temperature and degree of hydration on reactivity of UO/sub 2/ pellets, conversion of ammonium diuranate to UF/sub 4/, reduction of UF/sub 4/, melting and casting of Nb--U alloys, production of U washers, recovery of U from scrap material, and fabrication of Th electrodes. New processes, special problems, and wet chemical and spectrochemsical development were considered. (For preceding period see NLCO- 601.) (J.R.D.)
