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.
