1. 1. Evaluation and Mitigation of Industrial Fire Hazards

   Författare :Petra Andersson; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; Effect of fires; Accidental release; Water mist; Halon replacement; Industrial Fire Hazards; Human burns; Smoke detektion;

   Sammanfattning : A tool suitable for conducting industrial fire and explosion hazard analysis is presented, together with an identification of weak links in the hazard evaluation chain. For some of the weak links additional research has been carried out. LÄS MER

3. 2. Modelling the multifaceted physics of metallic dust and droplets in fusion plasmas

   Författare :Ladislas Vignitchouk; Svetlana Ratynskaia; Richard Pitts; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Plasma-material interaction constitutes one of the major scientific and technological issues affecting the development of thermonuclear fusion power plants. In particular, the release of metallic dust and droplets from plasmafacing components is a crucial aspect of reactor operation. LÄS MER

4. 3. Physical Characterization of Actinide Particles - A Study on Novel Techniques for Radiological and Nuclear Safeguard Investigations

   Författare :Ylva Ranebo; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; plutonium oxide particles; secondary ion mass spectrometry; uranium oxide particles; hot particles; vibrating orifice aerosol generator; scanning electron microscopy; nuclear safeguards;

   Sammanfattning : This thesis presents a study of advanced analytical techniques, for the characterization of actinide particles originating from the non-peaceful use of nuclear technology and from international inspections of the nuclear fuel cycle associated with non-proliferation agreements. The thesis is based on five papers, which will be referred to by Paper I-V in the text. LÄS MER

5. 4. Radioanalytical chemistry in emergency preparedness

   Författare :Ulrika Nygren; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Sammanfattning : Radioactive nuclides present a potential health hazard due to the ionising radiation emitted during their decay. The release of large amounts of radioactive nuclides is of concern both for man and the environment. LÄS MER

7. 5. Element transport in aquatic ecosystems – Modelling general and element-specific mechanisms

   Författare :Lena Konovalenko; Clare Bradshaw; Ulrik Kautsky; Linda Kumblad; Dan Baird; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radionuclides; elements; concentration ratio; bioaccumulation; biomagnification; fish; modelling; aquatic food web; ecosystem; Cs; Sr; environmental risk assessment; marin ekotoxikologi; Marine Ecotoxicology;

   Sammanfattning : Radionuclides are widely used in energy production and medical, military and industrial applications. Thus, understanding the behaviour of radionuclides which have been or may be released into ecosystems is important for human and environmental risk assessment. LÄS MER
