Processes

DIDPA

Di-iso-decylphosphoric acid

JAERI developed a partitioning process to separate elements in high-level liquid wastes into four groups: transuranium elements, Tc-platinium group metals (PGM), Sr-Cs and the remaining other elements. The DIDPA process is a solvent extraction process used to separate the TRU elements from nuclear waste in order to decrease its radiotoxicity.

SETFICS

Solvent Extraction for Trivalent f-elements Intra-group Separation in CMPO-complexant System

The Solvent Extraction for Trivalent f-elements Intra-group Separation in CMPO-complexant System (SETFICS) process could be considered as a modified TRUEX process, as it is based on the same CMPO solvent. SETFICS aims to recover An & Ln from a raffinate of SOFT PUREX in order to decrease the radiotoxicity of nuclear wastes.

TALSPEAK

Trivalent Actinide-Lanthanide Separations by Phosphorus-reagent Extraction from Aqueous Komplexes

The TALSPEAK (Trivalent Actinide Lanthanide Separations by Phosphorus-reagent Extraction from Aqueous Komplexes) process aims to separate An from Ln from an UREX raffinate.

ALSEP

An-Ln Separation

The ALSEP (Actinide-Lanthanide Separation) process is the last P&T process developed in the USA. This is a patented process that aims to directly separate the Am/Cm product from lanthanides from a raffinate of TBP cycle, as PUREX.

TRUEX

Transuranic Extraction

The TRUEX process is a solvent extraction process based on PUREX and aims to extract the transuranic elements (namely Pu, U, americium (Am), and curium (Cm)) from nuclear fuel wastes in order to reduce the alpha activity of these wastes.
