In a power plant scale fusion reactor, huge amount of thermal produced by the reaction and external heating must be exhausted through narrow area divertor targets. The targets withstand intense bombardment diverted particles where high heat fluxes are generated erosion takes place on surface. A considerable volumetric nuclear also exhausted. To cope with such an unprecedented exhaust challenge, highly efficient cooling capacity is required. Furthermore, fulfill other critical functions as...
Abstract ITER is of key importance in the European fusion roadmap as it aims to prove scientific and technological feasibility a future energy source. The EUROfusion consortium labs within Europe contributing preparation exploitation operation aspires exploit outcomes view DEMO. paper provides an overview major progress obtained recently, carried out frame new (initiated 2021) work-package called ‘ Pr eparation I TER O peration’ (PrIO). directly supported by eleven PrIO contributions given...
The spherical momentum distribution of the protons in ice is extracted from a high resolution deep inelastic neutron scattering experiment. Following recent path integral Car-Parrinello molecular dynamics study, data were successfully interpreted terms an anisotropic Gaussian model, with statistical accuracy comparable to that model independent scheme used previously, but providing more detailed information on three dimensional potential energy surface experienced by proton. A recently...
The OH stretching vibrational spectrum of water was measured in a wide range temperatures across the triple point, 269 K <T < 296 K, using Inelastic Neutron Scattering (INS). hydrogen projected density states and proton mean kinetic energy, <EK>OH, were determined for first time within framework harmonic description dynamics. We found that liquid value <EK>OH is nearly constant as function T, indicating quantum effects on frequency are weakly dependent temperature. In case ice, ab initio...
The methodological approach employed for the neutronics in PPPT (Power Plant Physics and Technology) programme of EUROfusion is presented. It encompasses development works on advanced computational tools activities related to nuclear design performance evaluation DEMO power plant including safety, maintenance, waste management issues. Development work conducted Monte Carlo codes, CAD geometry conversion simulations, coupled radiation transport activation computation systems. role data...
JET components are removed periodically for surface analysis to assess material migration and fuel retention. This paper describes issues related handling procedures preparing samples analysis; in particular a newly developed procedure cutting beryllium tiles is presented. Consideration also given the hazards likely due increased tritium inventory activation from 14 MeV neutrons following planned TT DT operations (DTE2) 2017. Conclusions drawn as feasibility of post DTE2.
Neutronics benchmark experiments are conducted at JET in the frame of WPJET3 NEXP within EUROfusion Consortium for validating neutronics codes and tools used ITER nuclear analyses to predict quantities such as neutron flux along streaming paths dose rates shutdown due activated components. The preparation rate future Deuterium-Tritium operations (DTE2 campaign) progress. This paper summarizes status measurements progress current Deuterium–Deuterium (DD) campaign efforts DTE2.
The Plasma Facing Components (PFCs) of the divertor target contribute to fundamental functions heat removal and particle exhaust during fusion operation, being subjected a very hostile complex loading environment characterized by intense particles bombardment, high fluxes (HHF), varying stresses loads significant neutron irradiation. development well-designed target, which represents crucial step in realization DEMO, needs assessment all these as accurately possible, provide pivotal data...
The Radial Neutron Camera (RNC) is a diagnostic system located in the ITER Equatorial Port 1 (EP01) composed by two sub-systems (i.e.: in-port and ex-port RNC) probing poloidal section of plasma through set fan-shaped Lines Sight (LOS). RNC designed to provide time resolved measurement neutron alpha particles source profiles total strength, application reconstruction techniques line-integrated fluxes. Ex-port sub-system 16 LOS distributed different toroidal planes enclosed massive shielding...
