Shutdown dose rate assessment with the Advanced D1S method: Development, applications and validation

• Development of Advanced-D1S for shutdown dose rate calculations.
• Recent applications of the tool to tokamaks.
• Summary of the results of benchmarking with measurements and R2S calculations.
• Limitations and further development.

The present paper addresses the recent developments and applications of Advanced-D1S to the calculations of shutdown dose rate in tokamak devices. Results of benchmarking with measurements and Rigorous 2-Step (R2S) calculations are summarized and discussed as well as limitations and further developments. The outcomes confirm the essential role of the Advanced-D1S methodology and the evidence for its complementary use with the R2Smesh approach for the reliable assessment of shutdown dose rates and related statistical uncertainties in present and future fusion devices.
