Study of heat transfer in a 7-element bundle cooled with the upward flow of supercritical Freon-12
(2012-04-01)
Experimental data on SuperCritical-Water (SCW) cooled bundles are very limited. Major problems with performing such experiments are: 1) small number of operating SCW experimental setups and 2) difficulties in testing and ...
An experimental study of the relative response of plastic scintillators to photons and beta particles within the context of tritium monitoring
(2011-08-01)
A scintillation counting system has been constructed with the use of BC-400 and EJ-212 series plastic scintillators along with a subminiature photomultiplier tube to investigate the effect of increasing plastic scintillator ...
Development and characterization of a dual neutron and gamma detector
(2011-08-01)
A dual neutron and gamma detection system has been developed for online measurements. The system consists of a single crystal mounted on a photomultiplier tube to detect simultaneously gamma radiation as well as thermal ...
Thermal aspects of using alternative nuclear fuels in supercritical water-cooled reactors
(2010-11-01)
A SuperCritical Water-cooled Nuclear Reactor (SCWR) is a Generation IV concept currently being developed worldwide. Unique to this reactor type is the use of light-water coolant above its critical point. The current research ...
Conceptual design of a thermal hydraulic loop for multiple test geometries at supercritical conditions named supercritical phenomena experimental test apparatus (SPETA)
(2012-04-01)
The efficiency of nuclear reactors can be improved by increasing the operating pressure of current nuclear reactors. Current CANDU-type nuclear reactors use heavy water as coolant at an outlet pressure of up to 11.5 MPa. ...
Determining the effectiveness of nuclear security through computer simulation
(2015-09-01)
There is a growing concern from both national regulators and the International
Atomic Energy Agency (IAEA) about the threat posed by attacks against iconic targets such as nuclear power plants. This has led to an increased ...
Development of a heat-transfer correlation for supercritical water in supercritical water-cooled reactor applications
(2009-12-01)
A large set of experimental data, obtained in Russia, was analyzed and a new heat-transfer correlation for supercritical water was developed. This experimental dataset was obtained within conditions similar to those for ...
Theoretical performance analysis of a novel hemispherical tissue equivalent proportional counter for neutron monitoring and dosimetry
(2016-02-01)
Neutron dosimetry in reactor fields is currently conducted using thermal neutron flux monitors. It has been demonstrated that Tissue Equivalent Proportional Counters (TEPCs) have the potential to improve the accuracy of ...
Simulation, design and construction of a gas electron multiplier for particle tracking
(2012-12-01)
The biological effects of charged particles is of interest in particle therapy, radiation protection and space radiation science and known to be dependent on both absorbed dose and radiation quality or LET. Microdosimetry ...
Simulation of in-core dose rates for an offline CANDU reactor
(2016-04-01)
This thesis describes the development of a Monte Carlo simulation to predict the dose rates that will be encountered by a novel robotic inspection system for the pressure tubes of an offline CANDU reactor. Simulations were ...
