Combustion of a liquid fuel in a rectangular channel

Combustion, Explosion, and Shock Waves, 2014
The possibility of flame spread over the surface of a liquid fuel (n-butanol) in two-phase flow with a gaseous oxidizer in a narrow rectangular channel is demonstrated. The results of a detailed experimental study of combustion in this system are given.

Zirconium ignition in exposed fuel channel

Nuclear Engineering and Design, 2015
Abstract A theoretical model based on simultaneous solution of the heat and mass transfer equations is developed for predicting the rate of thermo-chemical reaction between zirconium cladding and a hot steam environment. Ignition conditions relevant to cladding oxidation in an exposed fuel channel of a partially uncovered core are predicted based on ...

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%.

Uranium dioxide mass transfer in the central channel of the fuel kernel of a fuel element of a single-element energy-generating channel

Atomic Energy, 2009
The methods and computer program for calculating, as well as the computational results obtained, the remaining-life changes occurring in the profile of the central channel of the kernel of a fuel element in a single-element electricity generation channel because of uranium dioxide mass transfer, taking account of the redistribution of the fuel ...

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.

Evolution of pores in the fuel cladding of the electrogenerating channel

Physics of Atomic Nuclei, 2014
The results of reactor tests of carbonitride fuel in a monocrystalline cladding from a molybdenum-based alloy that were carried out earlier on an experimental setup Ya-82 for 8 to 300 h at a temperature of ∼1500°C can be used in order to prove the operational reliability of fuel elements in the design of a megawatt nuclear power plant for a spacecraft.

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 ...

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.

Multi channel voltage control for fuel cells

Journal of Power Sources, 2005
Abstract Cell voltage control is a safe method to evaluate the operation of the single cells even though large efforts are being made to stabilise the behaviour of the fuel cells over the whole operating range. For fully developed systems only voltage control of single cells is necessary, whereas in test benches it is necessary to record data of the ...
