TL;DR: In this article, a pyroprocessing integrated inactive demonstration facility (PRIDE) was constructed at KAERI and it began test operation in 2012 to test the process regarding unit process performance, remote operation of equipments, integration of unit processes, scale-up of process, process monitoring, argon environment system operation, and safeguards related activities.

TL;DR: In this paper, the separation characteristics of surrogate rare-earth fission products in a eutectic (LiCl-KCl) molten salt were investigated using an integrated rare earth separation apparatus comprising a precipitation reactor, a solid detachment device, and a layer separation device.

TL;DR: In this article, a self-pH-adjustment function was proposed for a multi-cell-stacked electrolyzer with an anion exchange membrane, where a portion of the ammonia solution from a pH adjustment reservoir was circulated through the cathodic chambers of the electrolyzer.

TL;DR: In this article, a process to recover pure uranium from contaminated (U,Gd)O 2 scraps generated from nuclear fuel fabrication processes by using the dissolution of (Gd,O 2) scraps in a carbonate with H 2 O 2 and the precipitation of the dissolved uranium as UO 4.

TL;DR: In this paper, the fabrication of a borosilicate glass based wasteform with a glass matrix of SiO2-Al2O3-B2O 3 having a high waste loading of 50% lanthanide oxide was reported.
