Caper Modifications and First Experimental Results on Highly Tritiated Water Processing with PERMCAT at the Tritium Laboratory Karlsruhe

Overview of R&D at TLK for process and analytical issues on tritium management in breeder blankets of ITER and DEMO

“…This operation should produce stoichiometric DTO (specific activity up to 5.2 × 10 16 Bq/kg) which is very challenging to handle and process. The CAPER facility [11] hosting a PERMCAT reactor has been especially upgraded to produce, handle and decontaminate HTW [22]. A staged approach is being implemented as depicted in Fig.…”

“…Using this configuration, about 10 runs were performed to study the influence of main process parameters (swamping ratio, purge gas pressure, and feed flow rate) on the detritiation factors (DF). About 25 g of HTW with specific activity up to 4.4 × 10 15 Bq/kg were processed [22]. • Stage 1-b: Some MSB previously loaded with detritiated HTW were placed upstream of the PERMCAT for a further detritiation.…”

Overview of R&D activities on tritium processing and handling technology in JAEA

“…The tritium processing technology has been developed for the system of ITER [10]. The blanket tritium technology is a remaining key issue for a DEMO fusion reactor [11].…”
