Rapid tritium accounting method based on the temperature gradient for a tritium storage and delivery system: an interpretation with experiments

Samuel Park, Jisoo Kim, Hyun-Goo Kang2020年被引用 1Nuclear FusionIF 3出版社

This paper proposes a rapid tritium accounting method that will enhance the tritium accountability of a tritium storage and delivery system (SDS) with in-bed calorimetry. We derive an accounting model with validation of assumptions based on the law of Newton's cooling. The characteristics of the accounting model enable rapid accounting by instantly measuring the temperature gradient of a tritium storage bed in natural cooling. We validate the accounting method with experiments that demonstrate a good trackability for tritium inventory in the storage bed. Further research with a dedicated design for the proposed method is necessary to improve the rapidity and accuracy of the SDS.

本論文は、トリチウム貯蔵・供給システム(SDS)におけるベッド内熱量測定を用いた迅速なトリチウム計量方法を提案するものである。我々は、ニュートンの冷却則に基づく仮定の検証を伴う計量モデルを導出する。この計量モデルの特性により、トリチウム貯蔵ベッドの自然冷却中の温度勾配を即時測定することで、迅速な計量が可能となる。我々は、実験を通じてこの計量方法を検証し、貯蔵ベッド内のトリチウムインベントリに対する良好な追跡可能性を示す。提案手法の迅速性とSDSの精度をさらに向上させるためには、専用設計に基づく追加研究が必要である。
