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...
MCNP and the ADVANTG code were used to analyse γ-dose rates for future Slovenian LILW repository. Using ADVANTG's variance reduction technique, different detailed calculations of achievable in a reasonable time, whereby analogue simulations accelerated up 9500 times. We analysed influence repository configurations on annual 150 m from outer edge The results show that, all open where waste sources is deposited, calculated lower than prescribed limitation (20 mSv/year). By considering also...
A closed-water activation loop is being built at the Jožef Stefan Institute TRIGA reactor in Slovenia to serve as a well-defined and stable source of high-energy gamma rays neutrons. The radial piercing port, which penetrates graphite reflector touching core was chosen for installation due high neutron flux favourable shielding conditions surrounding concrete bioshield. main objective this work assess dose field outside port obtain important details final design inner part irradiation...
Assessing radiation fields in the biological shield penetrations of fusion reactors is a challenging task. At Joint European Torus (JET) neutron field at larger distances from torus has been calculated and measured. JET operated 2021–22 with tritium-tritium plasma neutronics experiments were performed for validating real environment codes nuclear data applied ITER analyses. In particular, fluence neutrons passing through vacuum vessel hall was measured compared calculations order to assess...
The ADVANTG code was used to analyze dose rates from the proposed Slovenian silo-type low and intermediate level waste (LILW) repository. Detailed calculations of are challenging as gamma-sources located in thick concrete containers effect backscattering air has be considered. Compared analog MCNP simulations maximum relative speed-up up 9500 achieved by using ADVANTG. We have analyzed influence different repository configurations on final annual γ-dose rates. For measurement positions,...
