Radial distributions of power and fuel temperature in annular U3Si2 fuel with FeCrAl cladding
Annals of Nuclear Energy, 2020Abstract The present work performs systematic study on neutronic properties of annular fuel due to its high efficiency in heat transfer and low peak fuel temperature. Recent physical experiment on annular fuel indicates the present neutronic study is urgent and necessary.

High-Performance Annular Fuel Reactor Physics and Fuel Management
Nuclear Technology, 2007Compared to the traditional solid fuel pin, annular fuel with internal as well as external coolant flow increases the cooling surface by ∼50%, which allows a higher core power density. However, operating at high power density introduces challenges in the core physics design of burnable poison to suit the desired fuel cycle length.

Fertile-Free Annular Fuel for Plutonium Recycling
Nuclear Technology, 2007Up to 50% increase in the power density of the existing pressurized water reactor (PWR)-type reactors can be achieved by the use of internally and externally cooled annular fuel geometry. As a result, the accumulated stock-piles of Pu, especially if incorporated infertile-free inert matrix, can be burnt at a substantially higher rate as compared with ...

Temperature distributions in end closures of annular fuel elements
Nuclear Structural Engineering, 1965Abstract The temperature distributions in bonded end closures of annular fuel elements, such as those often used in nuclear superheating power reactors, are determined analytically. The solution for the temperature distributions is represented by products of the Bessel functions with hyperbolic functions.

Radiation and creep analysis of strains and stresses in annular fuel elements☆
Nuclear Engineering and Design, 1965Abstract A theoretical analysis for the determination of strains and stresses produced in long, annular reactor fuel elements is presented. In the analysis, primary effects of thermal-cycling growth, irradiation growth, swelling, creep and neutron flux levels developed in the fuel material are taken into account. An exact solution based on a product

Optimum configuration of an annular nuclear fuel element
Nuclear Engineering and Design, 1970Abstract In all-ceramic fuel elements for high temperature gas-cooled reactors, an unfueled moderator spine is often surrounded by a fuel compact consisting of a dispersion of fuel and fertile material in a moderator matrix with a ceramic cladding. For given fuel and fertile loading in a fuel element of given outer size, physical reasoning suggests ...

Influence of the Fuel Distribution in Double Annular Combustors on the Emissions
Russian Engineering Research, 2021The double annular combustor of a low-emission combustion chamber in a gas-turbine engine based on natural gas is considered. The distribution of fuel supply in the double annular combustor is investigated, and its influence on the toxic emissions is determined.
