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 ...

Liquid Fuel Combustion Using Heat Recirculation Through Annular Porous Media
Journal of Engineering for Gas Turbines and Power, 2005A counter-flow annular heat recirculating burner was designed for lean prevaporized, premixed combustion. Prior to entering the combustor, the reactants are passed through a porous media-filled preheating annulus surrounding the combustor. Kerosene is dripped by gravity onto the porous media and vaporized by the heat conducted through the combustor ...

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.

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.
