Safety analysis is part of the ITER Test Blanket Module (TBM) design process ensuring that the TBM does not adversely affect the safety of ITER. To get the licence for TBM as a whole with ITER, relevant safety analysis is required for each TBM system proposed by each party. The safety analysis for the Chinese Dual Functional Lithium–Lead Test Blanket Module (DFLL-TBM) has been performed based on the latest DFLL-TBM design. In this paper, the following safety considerations, such as source terms, operational releases, accident sequence analyses and waste assessment, were analysed. Both the deterministic approach and the complementary systematic approach starting with failure mode and effects analysis studies were adopted in the accidental analysis. The preliminary results showed that the DFLL-TBM system at normal operating conditions and under accident scenarios did not add additional safety hazards to the ITER machine and could meet the ITER safety requirements and additional safety requirements for the TBM system.

安全解析は、ITERテストブランケットモジュール(TBM)設計プロセスの一部であり、TBMがITERの安全性に悪影響を及ぼさないことを保証するものである。TBM全体としてITERとともに認可を取得するためには、各機関が提案する各TBMシステムについて関連する安全解析が必要とされる。中国の二重機能リチウム鉛テストブランケットモジュール(DFLL-TBM)の安全解析は、最新のDFLL-TBM設計に基づいて実施された。本論文では、線源項、運転時放出、事故シーケンス解析、廃棄物評価などの安全上の考慮事項を分析した。事故解析には、決定論的アプローチと、故障モード影響解析研究から始まる補完的体系的手法の両方が採用された。予備的結果は、DFLL-TBMシステムが通常運転条件下および事故シナリオ下においてITER機器に追加の安全上の危険性をもたらさず、ITER安全要件およびTBMシステムに対する追加安全要件を満たすことができることを示した。
