  2. 16. 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.

  7. 20. Modelling the Role of Nuclear Power and Variable Renewables in Climate Change Mitigation

    Author : Mariliis Lehtveer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy system model; nuclear power; multi-criteria analysis; variable renewables; climate change; optimisation;

    Abstract : As the number of people on Earth and our energy needs have increased the system for providing this energy has become ever more complex and complicated and thus the need for more systematic understanding of it has grown. However, change in energy system is slow and many of the challenges that we face such as mitigating climate change need global solutions. READ MORE
