Development of annular centrifugal contactors for TRPO process tests

摘要

The TRPO process has been developed in China for removing transuranium (TRU) elements from the high-level liquid waste (HLLW) since 1980s. In order to meet the requirements of the TRPO process tests, a series of annular centrifugal contactors have also been developed at the Institute of Nuclear and New Energy Technology (INET), Tsinghua University, China. In particular, the ?10 mm annular centrifugal contactor has been applied successfully in laboratory scale tests of the TRPO process. The ?70 mm annular centrifugal contactor for semi-industry scale tests of the TRPO process has good performance and two design characteristics, namely a modular design and an overflow structure.
