2. 1. 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.

4. 2. Accelerator-driven systems : safety and kinetics

   Author : Marcus Eriksson; Janne Wallenius; Hamid Aït Abderrrahim; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik;

   Abstract : The accelerator-driven system (ADS) is recognized as a promising system for the purpose of nuclear waste transmutation and minimization of spent fuel radiotoxicity. The primary cause for this derives from its accelerator-driven, sub-critical operating state, which introduces beneficial safety-related features allowing for application of cores employing fuel systems containing pure transuranics or minor actinides, thereby offering increased incineration rate of waste products and minimal deployment of advanced (and expensive) partitioning and transmutation technologies.

5. 3. Surrogate Measures of Safety with a Focus on Vulnerable Road Users : An exploration of theory, practice, exposure, and validity

   Author : Carl Johnsson; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trafiksäkerhet; Indirekta trafiksäkerhetsindikatorer; Oskyddade trafikanter; Videoanalys; Surrogate measures of safety; Traffic safety; Vulnerable road user safety; Traffic conflicts; video analysis;

   Abstract : Surrogate measures of safety (SMoS) are meant to function as tools to investigate traffic safety. The term surrogate indicates that these measures do not rely on crash data; instead, they focus on identifying safety critical events (or near-crashes) in traffic, which can be used as an alternative to crash records.

6. 4. Complexity and Ambivalence in Ship Safety Inspection : The view of Swedish Port state control officers

   Author : Fredrik Hjorth; Carl Hult; Ulf Drugge; Michael Baldauf; Linnéuniversitetet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inspection; Port state control; Detention; Deprofessionalization; Compliance; Maritime safety; Profession; Bureaucracy; Sjöfartsvetenskap; Maritime Science;

   Abstract : Despite an extensive system of Port state controls (PSC) on ships, inspection loopholes in European control functions have been reported. Furthermore, risk factors associated with fatigue, stress and a poorly developed safety culture on board ships have been identified in earlier research. READ MORE

7. 5. Work Practice, Safety and Heedfulness : Studies of Organizational Reliability in Hospitals and Nuclear Power Plants

   Author : Vincent Gauthereau; Karlene H. Roberts; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The study of safety in complex systems has focused on different issues over the past decades. This focus was often linked to the conclusions of previous accidents' / incidents' analyses. When accidents were attributed to technical causes, safety research focused on technical developments.
