USNC-Technologies (USNC-Tech) is an advanced nuclear company focused on developing space power and propulsion systems to enable high-impact science missions the growth of a self-sustaining in-space economy. As subsidiary Ultra Safe Nuclear Corporation (USNC), USNC-Tech has leveraged technologies experience gains from design, licensing, deployment terrestrial gas-cooled reactors for these system...

The paper presents the results of studies on burning minor actinides (MA) extracted from SNF thermal reactors in a BN-600 reactor, which uses complete set MAs instead traditional nuclear fuel types: uranium and/or plutonium. advantages such approach to MA are that long-lived waste is recycled and energy produced can be used, e.g., generate electricity. Besides, where, reactor with or MOX used f...

European Union’s (EU) (currently 27 Member States) shared-cost research has been organised in Framework Programmes (FP) of durations of 4-5 years since 1984. The 6th European Atomic Energy Community (EURATOM) Framework Programme (2002-06) and the current 7th FP (2007-11) have been allocated a fission research budget respectively of 209 and 287 Million Euro from the European Community (EC). In F...

This paper reviews the recent three-year progress on investigations of pebble bed flows in nuclear engineering. Both application beds fission reactors and fusion are included. The fundamental characteristics packing, flows, conduction, convection, radiation, effective thermal conductivity reviewed. important issues design as well that related to reactor safety also introduced. In addition, adva...

The prediction of reactor antineutrino spectra will play a crucial role as experiments enter the precision era. positron energy spectrum 3.5 million inverse beta decay reactions observed by Daya Bay experiment, in combination with fission rates fissile isotopes reactor, is used to extract resulting from specific isotopes. This information can be produce precise, data-based other different fract...

Objectives . The paper aimed to review and analyze the results of works devoted numerical modeling experiments on interaction high-power ultraviolet (UV) laser pulses with condensed targets. were carried out at GARPUN, powerful KrF-laser facility P.N. Lebedev Physical Institute Russian Academy Sciences (Moscow). relevance research is related use excimer UV lasers as a driver for thermonuclear r...

The energy spectrum of fission neutrons in the biological irradiation field of the Kinki University reactor, UTR-KINKI, has been determined by a multi-foil activation analysis coupled with artificial neural network techniques and a Au-foil activation method. The mean neutron energy was estimated to be 1.26 +/- 0.05 MeV from the experimentally determined spectrum. Based on this energy value and ...
