Storage of radioactive aqueous wastes from Purex processes [PDF]
, 1952 The radioactive liquid wastes from a separations facility are customarily stored in underground waste storage tanks. The wastes from the proposed Purex Separations Plant will have a high concentration of the fission products and will result in a large evolution of heat.

AIChE Journal, EarlyView.Abstract Recovery of rare earth elements (REEs) from end‐of‐life (EOL) products represents a strategic opportunity to strengthen the domestic supply chain for rare earth elements. This work presents a superstructure‐based optimization framework for finding the most economical processing pathway for different EOL rare earth permanent magnets (REPMs ...

New Waste Calcining Facility Non-radioactive Process Decontamination [PDF]
, 2001 This report documents the results of a test of the New Calcining Facility (NWCF) process decontamination system. The decontamination system test occurred in December 1981, during non-radioactive testing of the NWCF. The purpose of the decontamination system test was to identify equipment whose design prevented effective calcine removal and ...
