HTGR fuel and fuel elements

Energy, 1991
Abstract The state of the art for fuel and uranium-graphite fuel elements for HTGRs being developed in the USSR is described. The results of investigating the main characteristics of the spherical fuel element materials and components are reported. Included in the studies are: uranium dioxide microspheres, protective pyrocarbon and silicon carbide ...

Closure of fuel elements

Nuclear Engineering and Design, 1966
Abstract A method is described for the end closure of claddings of fuel elements obtained by hot swaging. Cladding materials are dispersion hardened metals, and particularly SAP (synthered aluminum with Al2O3 dispersion) and NiTD ∗∗ (nickel synthered with ThO2 dispersion). Results obtained are reported in the present paper.

Design of fuel elements

Nuclear Engineering and Design, 1972
Abstract This lecture concentrates on design features which may limit the performance of water-cooled power reactors. However, a comprehensive review of all aspects of design is beyond its scope. Apart from achieving its target in terms of reactivity life and thermal and hydraulic performance, a fuel element has done its job if it endures to its ...

Temperature inside the fuel elements

2009
Chapter 2 gives the methods for describing steady and transient temperature fields in the fuel elements. Some information is provided regarding influence of the cladding oxidation, hydrogen diffusion, and corrosion product deposition on the temperature fields.

Multiregion Fuel Elements

Nuclear Science and Engineering, 1962
A multiregion fuel element is described that can be designed to take advantage of the high density and high thermal conductivity of the metal as well as of the high operating temperature of the oxide. This is accomplished by using a rod-shaped element having an outer annulus of metal and a central core of oxide.
