The ITER tritium systems

Characterisation of a multitube PERMCAT reactor in view of a technical facility for highly tritiated water processing at the Tritium Laboratory Karlsruhe

“…Such water is mainly produced from the catalytic oxidation of tritium in different detritiation systems. The Combined Electrolysis Catalytic Exchange (CECE) process was chosen for ITER to process at least 20 kg h −1 of tritiated water with mean and maximal specific activity of 0.4 × 10 12 Bq kg −1 and 11.1 × 10 12 Bq kg −1 respectively [1]. This process is already developed and a decontamination factor (DF) of 2.5 × 10 5 was demonstrated at technical scale using the TRENTA facility at TLK [2].…”

RAMI analysis for ITER fuel cycle system

“…The principal functionality of the fuel cycle system is to provide fuel during plasma operation with the support of three individual systems [1,2]. First, the tokamak VV (Vacuum Vessel) will be fueled by PIS (Pellet Injection System) and NB (Neutral Beam) injection system.…”

“…The ITER fuel cycle system is expected to inject fuelling gas/pellets to the tokamak, as well as to recycle exhaust tritium as next fuel source with high reliability and availability [1,2]. The fuel cycle system is one of the key elements and challenges for the project, it should demonstrate reasonably high reliability and availability during the plasma operation.…”

Conceptual design on interface between ITER and tritium extraction system of Chinese helium-cooled solid breeder test blanket module

“…c) Measure and account tritium amount to obtain essential experimental data. According to ITER fuel cycle design [3], tokamak exhaust processing (TEP) system has the function to separate Q 2 from various tritiated fluids and then transfer them to isotope separation system (ISS) for tritium and deuterium recovering. Thus TBM TES only need to separate Q 2 from helium purge gas and deliver to ITER TEP for further processing.…”
