  2. 6. On-Line Monitoring Applications in Nuclear Power Plants

    Author : Hashem Mehrdad Hashemian; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calibration monitoring; noise analysis; instrumentation and control; sensing line blockages; Nuclear power plants; sensor response time testing; reactor diagnostics; next generation reactors; applied research;

    Abstract : As the current generation of nuclear power plants have passed their mid-life, increased monitoring of their health is critical to their safe operation. This is especially true now that license renewal of nuclear power plants has accelerated, allowing some plants to operate up to 60 years or more. READ MORE

  4. 7. 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

  5. 8. Measures and method characteristics for early evaluation of safe operation in nuclear power plant control room systems

    Author : Eva Simonsen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control room; early development; human factors engineering; safe operation; resilience engineering; evaluation methods; nuclear power;

    Abstract : Safe operation is a central objective for high-risk industries such as nuclear power plants. Operation of the plant is managed from a central control room, which is a complex socio-technical system of physical and organisational structures such as operators, procedures, routines, and operator interfaces.

  6. 9. Structural integrity of prestressed nuclear reactor containments

    Author : Patrick Anderson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel liner; reliability; relaxation; shrinkage; creep; loss of prestress; tendon; Nuclear; containment; design pressure; Construction technology; Anläggningsteknik;

    Abstract : A nuclear power plant is provided with an extensive defense intended to prevent radioactive discharge in case of a reactor accident. This defense is built up of several independent safety barriers, where the reactor containment constitutes the last barrier to the environment. READ MORE

  7. 10. Polymeric materials in nuclear power plants : Lifetime prediction, condition monitoring and simulation of ageing

    Author : Erik Linde; Ulf Gedde; Mikael Hedenqvist; Sue Burnay; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Nuclear power plants generate a significant part of the world’s electrical power consumption. However, many plants are nearing the end of their designed lifetime, and to extend the lifetime it is important to verify that every component can withstand the added service time. This includes polymeric materials, which become brittle with time. READ MORE
