Get this from a library! Reactor core monitoring: background, theory and practical applications. [Mihály Makai; János Végh] -- This book presents a comprehensive overview of the computerized core monitoring techniques currently employed at pressurized water reactor (PWR) and boiling water reactor (BWR) nuclear power plants. Therefore the VENUS reactor at in Mol (Belgium) was modified towards a fast core (VENUS-F) and coupled to the GENEPI-3C accelerator built by CNRS The accelerator can operate in both continuous and pulsed mode.
The basic operation of the CANDU design is similar to other nuclear reactors. Fission reactions in the reactor core heat pressurized water in a primary cooling loop.A heat exchanger, also known as a steam generator, transfers the heat to a secondary cooling loop, which powers a steam turbine with an electric generator attached to it (for a typical Rankine thermodynamic cycle). subcritical fast reactor to an accelerator whose light ion beam hits a heavy material spallation target immersed inside its lead alloy cooled core, so as to provide the extra external neutrons needed to sustain the power delivered by the reactor core.

Pulsed-source experiments in a reflected coupled-core reactor Model D required estimates of the fast and thermal transit times, t f and tp. The t f selected, 1 -5 x ' sec was derived from the fast-group constants used in part I. The model was not particularly sensitive however to the value of t by: 1.
Kinetics Experiments on Coupled Cores in the ZED-2 Reactor by H. Hinds, F. McDonnell and D. Walker ABSTRACT A -series of space-time kinetics experiments has been performed in the ZED-2 reactor. The main purpose of the experiments was to provide a set of data with which to test the adequacy of spatial kinetics codes and models.
Solids holdup in the affected riser regions increased with increasing static bed height in the upper fluidized bed. For the coupled reactor, the restriction of riser outlet was determined by the sum of distributor pressure drop (Δ P D = (ζ / α 2) (U g, r 2 / 2) ρ m) and static pressure of the fluidized bed (Δ P b = H b g ρ p ε ¯ sp).Cited by: 4.
Reactor core of AHWR is divided into 17 non-overlapping nodes. Non-linear model of AHWR is characterized by 90 first order differential equations. Total reactor power and 17 nodal powers are. The systematics of coupling reactivity and time delay between cores have been investigated with a series of coupled-core assemblies on the AAEC Split-table Critical Facility.
The assemblies were similar to Static Measurements in Coupled Cores in the Zed-2 Reactor. book Universities' Training Reactor (UTR), but had graphite coupling Author: JR Harries. This benchmark problem originates from the ANL Benchmark Problem Book (Argonne Code Center, ). It is a 2D, 2-group reactor core model with no reflector region (Hageman and Yasinsky, ).
The core is smaller (hence the spatial regions are more tightly coupled) and the spatial variation of the flux varies moderately over the by: 1. A static, full core calculation for IAEA 10 MWth Material Test Reactor (MTR) benchmark problem is carried out using a standard set of computer code systems, namely: (i).

A hybrid coupled strategy was proposed for a coupled neutronics and thermal-hydraulics analysis of a full PWR core, using the continuous-energy Reactor Monte Carlo code (RMC) and the sub-channel.
ZEEP was also used during this period by scientists from the UK to measure the properties of fuel rods to be used in a proposed UK heavy-water power reactor. Near the end of this period lattice experiments were done with rod clusters of uranium metal, similar.

Static and dynamic neutronic analyses have been performed on an innovative burst-mode Ultrahigh-Temperature Vapor Core Reactor (UTVR) space nuclear power system. This novel reactor concept employs multiple neutronically coupled fissioning cores and operates on a direct closed Rankine cycle using a disk magnetohydrodynamic generator for energy.

“ Use of an Optical Probe for Time-resolved in situ Measurement of Local Air-to-fuel Ratio and Extent of Fuel Mixing with Applications to Low NOx Emissions in Premixed Gas Turbines.” Proceedings of the Combustion Institute – An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line.
It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains.
