  5. 3. Inherent Safety Features and Passive Prevention Approaches for Pb/Bi-cooled Accelerator-Driven Systems

    Author : Johan Carlsson; KTH; []
    Keywords : Inherent Safety; Passive Safety; Accelerator-Driven Systems; ADS; nuclear waste; emergency decay heat removal; natural convection; thermal radiation;

    Abstract : This thesis is devoted to the investigation of passivesafety and inherent features of subcritical nucleartransmutation systems - accelerator-driven systems. The generalobjective of this research has been to improve the safetyperformance and avoid elevated coolant temperatures inworst-case scenarios like unprotected loss-of-ow accidents,loss-of-heat-sink accidents, and a combination of both theseaccident initiators.
