The EUROfusion Safety and Environmental Work Package (WPSAE) has the scope to progress safety studies for future EU DEMO reactor. A Generic Site Report (GSSR) been prepared include all steps necessary cover issues of nuclear fusion plant, from definition principles requirements, through detection source terms at risk, selecting postulated initiating events, analyzing accidents, quantifying doses population investigating waste production its management. Eleven GSSR volumes collate performed....
The Grup de Física les Radiacions (GFR) of the Universitat Autònoma Barcelona (UAB), in collaboration with Institute for Radiological Protection and Nuclear Safety (IRSN), has developed a passive Bonner sphere system (UAB-BSS), gold foils as thermal neutron detectors, application pulsed fields or mixed neutron-photon high photon intensities. In such fields, active devices suffer from saturation dead-time effects. MCNPX Monte-Carlo code been used to determine response neutrons different...
The use of high-energy linear electron accelerators (LINACs) for medical cancer treatments is widespread on an international scale. associated bremsstrahlung X rays may produce neutrons as a result subsequent photonuclear reactions with the different materials constituting accelerator head. generated neutron field highly variable and depends strongly beam energy, shielding, flattering filter well movable collimators (jaws) design irradiation geometry. An estimate this photoneutron component...
Demonstrating tritium self-sufficiency is an important goal of the European tokamak demonstration fusion reactor. Currently four breeder blanket concepts are being considered: Helium Cooled Pebble Bed (HCPB), Lithium-Lead (HCLL), Dual (DCLL) and Water (WCLL). Differences in materials construction lead to differing nuclear responses. As well as affecting breeding this also particular importance safety analyses, such modelling loss coolant accidents, it affects blanket's decay heat nuclide...
The IFMIF-DONES (International Fusion Material Irradiation Facility-DEMO Oriented NEutron Source) facility is being designed with the general objective of providing irradiation representative samples power fusion machine materials under prototypical conditions. A linear accelerator will deliver deuterons at high intensity to circulating lithium in a loop, which produce neutrons capable obtaining required damage As result this process, radionuclides be produced as by-product, characterized by...
Positron emission tomography (PET) is a non-invasive medical imaging technique normally used for diagnostic purposes to determine the location and concentration of physiologically active compounds in human body. An unshielded cyclotron PET at Clinica Universitaria de Navarra produce short-lived positron emitting radionuclides (15O, 13N, 11C 18F) by bombarding appropriate target material with proton or deuteron beams energies up 18 9 MeV, respectively. Subsequent nuclear reactions may...
A preliminary beam dump cartridge design has been proposed recently for the IFMIF-EVEDA accelerator. Copper was material chosen stop. In this paper we investigate possibility of designing a practical shielding so that it can offer an acceptable radioprotection response during both beam-on and beam-off phases. The analysis is performed whole component located inside already designed accelerator vault. comprehensive methodology to deal with problem. Special attention paid treatment neutron...
The IFMIF-DONES Facility is a unique first-class scientific infrastructure whose construction foreseen in Granada, Spain, the coming years. Strong integration efforts are being made at current project phase aiming harmonizing ongoing design of different and complex Systems facility. consolidation Diagnostics Instrumentation, transversal across many them, key element this purpose. A top-down strategy proposed for systematic Review Requirement definition, putting emphasis one-of-a-kind...
In large fusion machines, as the foreseen DEMO, high energy neutrons produced will cause transmutation of interacting materials which become a source radioactive waste. Besides main constituents material that could transmute but presence is essential, impurities often give rise to significant additional activation compared base material. Thus, once identified nuclides generating dominant products for DCLL (Dual Coolant Lithium-Lead) concept Breeding Blanket (BB) European objective study has...
A systematic methodology has been applied with the help of virtual simulation tools for a conceptual study an industrial light vehicle concept assembly. All workstations have defined throughout manufacturing process. With this methodology, ergonomic studies newly developed at every workstation in way that connects classical methodology. These focused especially on those workplaces, which offered worst working conditions. The use provided step-by-step overall vision assembly process from...
In the framework of collaboration between Universidad Autónoma de Barcelona and INFN Frascati National Laboratories, an experimental Bonner Sphere neutron spectrometry exercise has been performed in 2.5 MeV 14.2 quasi monoenergetic beams ENEA Fast Neutron Generator.
