日本原子力研究開発機構は、開発途上国等への世界展開を目指し、蒸気タービンによる発電、工業プロセスへの高温蒸気や地域暖房への低温蒸気供給を行う小型高温ガス炉システムの概念設計を実施した。小型高温ガス炉の炉心熱流動設計では、燃料の熱的健全性を確保するために、燃料最高温度の評価が重要となるが、その算出・評価をパーソナルコンピュータ(PC)上で簡便に行えるように、Microsoft Excelをベースとした計算ファイルを開発した。本報告書では、計算で使用される基礎式、計算方法と手順及び検証計算結果について述べる。

The Japan Atomic Energy Agency has performed the conceptual designs of small-sized High Temperature Gas-cooled Reactor (HTGR) systems, aiming for the deployment of the systems to overseas such as developing countries. The small-sized HTGR systems can provide power generation by steam turbine, high temperature steam for industry process and/or low temperature steam for district heating. In the core thermal and hydraulic designs of HTGRs, it is important to evaluate the maximum fuel temperature so that the thermal integrity of the fuel is ensured. In order to calculate and evaluate the fuel temperature on personal computers (PCs) in a convenient manner, the calculation file based on the Microsoft Excel were developed. In this report, the basic equations used in the calculation file, the calculation method and procedure, and the results of the validation calculation are described.
