A Fuel Channel Design for CANDU-SCWR

Volume 3: Structural Integrity; Nuclear Engineering Advances; Next Generation Systems; Near Term Deployment and Promotion of Nuclear Energy, 2006
The CANDU®-Supercritical Water Reactor (CANDU-SCWR) is one of the six reactor concepts being considered by the Generation-IV International Forum (GIF) for international collaborative R&D. With SCW coolant, the thermodynamic efficiency is increased to over 40%.

Downdraft Channel Gasifier Furnace for Biomass Fuels

Transactions of the ASAE, 1985
ABSTRACT THE development of a downdraft multi-channel gasifier for biomass fuels, starting in 1980, has resulted in an efficient design which can be scaled up as desired. Development problems and solutions are described. Capacity, temperature, efficiency and emissions tests are discussed and results given.

Droplet Dynamics in PEM Fuel Cell Flow Channels

Volume 10: Fluids Engineering, 2021
Abstract During the operation of proton exchange membrane (PEM) fuel cells, water is produced in the cathode side. The produced water passes through the porous structure of the electrode and emerges from the surface of the gas diffusion layer (GDL) within the flow channel.

Performance Prediction of Side Channel Type Fuel Pump

Journal of Fluid Machinery, 2003
The periphery pump (or regenerative pump) has been generally applied in the automotive fuel pump due to their low specific speed (high heads and small flow rate) with stable performance curves. In this study, the performance prediction of side channel type periphery pumps has been developed.

Water Removal From Hydrophilic Fuel Cell Channels

Journal of Fuel Cell Science and Technology, 2008
This paper describes an approximate method for analyzing two-phase flow of gas and liquid water in fuel cell channels, whose surfaces are sufficiently hydrophilic for liquid water to wick spontaneously into the channel corners. This analysis is used to address the important question of whether the gas flow at typical stoichiometries in such channels is

Heat-Loss Calculations in a SCWR Fuel-Channel

18th International Conference on Nuclear Engineering: Volume 2, 2010
The objective of this paper is to calculate heat losses from a CANDU-6 fuel-channel while modifying it according to the specified operating pressure and temperature conditions of SuperCritical Water-cooled Reactors (SCWRs). Heat losses from the coolant to the moderator are significant in a SCWR because of high operating temperatures (i.e., 350–625°C ...

Material Degradation in ACR-700 Fuel Channel Components

Volume 7: Operations, Applications, and Components, 2006
The ACR (Advanced CANDU Reactor)-700 shares many design features with operating CANDU (CANada Deuterium Uranium) reactors, such as horizontal pressure tubes, heavy water moderator, and on-line fueling. However, there are some departures from the operating reactors that could affect the performance of structural materials.

A BWR Fuel Channel Tracking System

1988
A relational database management system with a query language, Refer-erence I, has been used to develop a Boiling Water Reactor (BWR) fuel channel tracking system on a microcomputer. The software system developed implements channel vendor and Nuclear Regulatory ommission recommendations for in-core channel movements between reactor operating cycles.

Fuel channel friction and thermal irreversibilities in a proton exchange membrane fuel cell

International Communications in Heat and Mass Transfer, 2006
In this article, entropy production of gas friction and thermal irreversibilities in a rectangular channel of a proton exchange membrane fuel cell (PEMFC) is studied. A 2-D formulation of gas motion, heat transfer and entropy production is developed.

Multi-channel Optical Fiber Thermometer for PEM Fuel-Cell Applications

International Journal of Thermophysics, 2011
Miniature, durable, and fast-responding temperature sensors are needed for proton exchange membrane fuel cells (PEMFCs). When embedded in a single cell or in a cell stack, they can provide useful information both at the design stage for optimizing the cell efficiency and during operation for monitoring the working conditions and thus preventing ...
