TEHDGA吸着材にガンマ線及びHe$$^{2+}$$イオンビーム(例えば$$^{241}$$Amからのアルファ線を模擬したもの)を照射し、水素ガス発生量、浸漬3M硝酸$$_{3}$$溶液中の有機物の溶出量、熱特性及び分解生成物の化学種を評価した。これらを組み合わせて、1kGy/hの線量率のラフィネートからMAを分離回収プロセスの運転安全性を評価した。

The gamma-ray and He$$^{2+}$$ ion beam (which is simulated for alpha-ray from $$^{241}$$Am, for example) were irradiated on the TEHDGA adsorbent to evaluate the hydrogen gas production, leaching amount of organics in the immersed 3 M HNO$$_{3}$$ solution, thermal characteristics and speciation of the degradation products. These were combined to assess the safety of the 1st run of the MA separation process from the raffinate at a dose rate of 1 kGy/h.
