2. 1. Safety Reviews of Technical System Modifications in the Nuclear Industry

   Author : Thomas Falk; Sven-Ove Hansson; Teemu Reiman; KTH; []
   Keywords : safety; safety review; nuclear; nuclear power plant; process; process improvement; action research; experience feedback;

   Abstract : The function of safety reviews (here understood as expert judgements on proposals for design modifications and redesign of technical systems in commercial Nuclear Power Plants, supported by formalised safety review processes) plays a fundamental role for safety in nuclear installations. The primary aims of the presented case studies includes: critically examining and identifying the main areas for improvement of the existing technical safety review process as it is conducted at a Swedish nuclear power plant, developing a new process, and evaluating whether any improvements were accomplished.

4. 2. Lean Remanufacturing : Reducing Process Lead Time

   Author : Jelena Kurilova-Palisaitiene; Erik Sundin; Bozena Poksińska; Mats Björkman; Martin Kurdve; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular Economy; Lean Production; Toyota Production System; Value Stream Mapping; Remanufacturing Process Challenges and Improvements; Process Efficiency;

   Abstract : Remanufacturing is a product recovery option in which used products are brought back into useful life. While the remanufacturing industry stretches from heavy machinery to automotive parts, furniture, and IT sectors, it faces challenges. READ MORE

5. 3. Safety Evaluation of Road Characteristics

   Author : Sarbaz Najib Othman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident data; FOT data; Overtaking maneuvers; Road safety; PC-Crash; Critical road parameters; Horizontal curves;

   Abstract : Accidents are rare and widely distributed on the road network, which poses a challenge for road safety improvement. Traditional methods alone, such as accident analyses and experimental studies, do not explain all accident causation factors. READ MORE

6. 4. Studies of safety and critical work situations in nuclear power plants : a human factors perspective

   Author : Lena Kecklund; Erik Hollnagel; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Safety; nuclear power; operators; work-related factors; performance; human error; annual outage; MTO; Psychology; Psykologi; psykologi; Psychology;

   Abstract : The purpose of this thesis was to develop and apply different approaches for analyzing safety in critical work situations in real work settings in nuclear power plants, and also to identify safety enhancing measures by using the framework of interaction between human, organizational and technical subsystems (MTO, man-technology-organization). A Cognitive Psychology as well as a Stress Psychology framework was used. READ MORE

7. 5. Mathematical Models for Investigation of Performance, Safety, and Aging in Lithium-Ion Batteries
