Safety Design Guidelines (SDG) on Safety Approach and Design Conditions for Generation-IV Sodium-cooled Fast Reactor System [7. Joint IAEA-GIF Technical Meeting/Workshop on the Safety of Liquid Metal Cooled Fast Reactors]

Scope of SDG on Safety Approach: • This report is intended to provide recommendations and guidance on how to comply with the GIF SFR Safety Design Criteria. It presents examples for the measures stated in criteria as the best practices to help the designers achieve high levels of safety. • Initially, the guidelines will focus on specific safety concerns, such as reactivity characteristics of SFRs and heat removal issues. • To address the potential consequences of such accidents, this report focuses on providing examples of design approaches for ''prevention and mitigation of severe accidents'' and for ''loss-of-decay heat removal capability as a situation that needs to be practically eliminated''
