Pebble bed reactors fuel elements are specially suited for withstanding very high burn-up values. This is one of the main characteristics of a transmutation fuel. The higher the burn-up achieved in the fuel, the smaller the number of reprocessing steps needed for obtaining a high transmutation rate. In this paper, a new transmutation cycle option will be introduced, based in a single pass of th...

The influence of combustor size and shape on material feasibility is explored using (structural and fuel) weight, as well as fuel economy as metrics. Amaterials selection methodology developed for actively cooled rectangular panels has been embellished to include cylindrical/annular configurations. The procedure incorporates an analytical model for temperature and stress distributions subject t...

This paper presents the development of a nonlinear state observer to estimate the different gas species concentration profiles in a Proton Exchange Membrane Fuel Cell energy system. The selection of the estimated states follows functionality and fuel cell performance criteria. The implementation is based on the finite element discretisation of a fuel cell distributed parameter model. Forward an...

background: decrease of economically accessible uranium resources motivates consideration of breeding of fertile elements such as thorium. material and method: thorium oxide fuel burn up calculation of a simulated research reactor cooled heavy water has been proposed in the present work using mcnpx 2.6 code. two 233u and 235u isotopes have been used as fissile element of thorium oxide fuel. 135...

The trace element content of clinkers (and possibly of cements) can be used for the qualitative identification (i.e. manufacturing factory). Several hundred clinker sorts have been analysed (by replicated quarterly samples, collected from all Hungarian cement factories as well as from factories of 8 foreign countries) to determine their Mg, Sr, Ba, Mn, Ti, Zr, Zn and V content. The first 6 elem...

Monolithic fuels are the most promising candidate for a next generation of high-density research reactor fuels. If successfully developed, the remaining HEU-fueled reactors in the world could presumably be converted to low-enriched fuel — and the use of highly enriched uranium in the civilian nuclear fuel cycle eventually terminated. The most challenging type of reactors to convert are single e...
