The MARIA research reactor is designed and operated as a multipurpose nuclear installation, combining material testing, neutron beam experiments, medical industrial radionuclide production, including molybdenum-99 (99Mo). Recently, after fuel conversion to LEU rejuvenation of the staff while maintaining their experience, has been used respond increased interest scientific community in advanced power studies, both fission fusion. In this work, we would like introduce MARIA’ s capabilities...
International Fusion Materials Irradiation Facility — DEMOOriented Neutron Source (IFMIF-DONES) is a planned powerful neutron source, which will generate an intense flux of neutrons (up to ∼1015n/s/cm2) with fusion-relevant energy spectrum. It be accelerator source based on deuteron beam - lithium target reactions. The engineering design IFMIF-DONES elaborated in the frame Early work package EUROfusion consortium. facility dedicated irradiation suitable structural materials for construction...
This paper presents the results of fast neutron irradiation (E n > 0.5 MeV) an EJ-276 scintillator performed in MARIA research reactor with fluence up to 5.3×10 15 particles/cm 2 .In our work, four samples size φ 25.4 mm×5 mm were tested.The changes light yield, emission and absorption spectrum neutron/gamma discrimination using PuBe source before after are presented.The figure merit based on charge integration method for different fluences short gate times determined.
We report a new half-life measurement of the 188-keV isomeric state in $^{184}\mathrm{Re}$. The $^{184m}\mathrm{R}\mathrm{e}$ isomer was produced by means neutron activation natural rhenium foil MARIA nuclear reactor at National Centre for Nuclear Research (NCBJ). observation decay over two periods has yielded value ${T}_{1/2}=177.25\ifmmode\pm\else\textpm\fi{}0.07$ d. Our result is most precise determination $^{184m}\mathrm{Re}$ and improves precision previously known...
A simple model, for the estimation of changes in nuclear fuel element cladding temperature as well conditions formation onset nucleate boiling, is proposed. The results this are sufficient to assess effect transient with peak reactor's power on device's safety, without need time-consuming thermal calculations. basic parameters determined using proposed model maximum wall device a hot spot, time constant change, and course boiling ratio time. may be used investigating behavior thin...
