Specifics of forced-convective heat transfer to supercritical CO2 flowing upward in vertical bare tubes
(2015-04-01)Heat transfer in the forced convection regime of fluids at supercritical conditions has been studied extensively for the past 60 years. The dominant approach to summarize the experimental results was by proposing empirical ... -
Characterization of eutectic In-Bi-Sn alloy (Field’s metal) for use in single and two-phase liquid metal flow in natural circulation systems
(2015-04-01)An In-Bi-Sn eutectic alloy was characterized for the purpose of liquid metal natural circulation experiments. The alloy was chosen to reduce the power requirement and enhance the safety of these types of experiments. The ... -
Dosimetric characterization of a miniature x-ray source for biophysics studies
(2015-07-01)Tritium is a low energy beta emitter that is found in abundance at CANDU nuclear power plants and is a cause of concern since it accounts for roughly thirty three percent of the total occupational exposure of nuclear ... -
Monte Carlo simulations for the purpose of efficiency curve calibration for the Fastscan whole body counter
(2015-08-01)In order to be able to qualify and quantify radiation exposure in terms of dose, a Fastscan whole body counter must be calibrated correctly. Current calibration methods do not take the full range of body types into ... -
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 ... -
Study on supercritical fluids in an intermediate heat exchanger for an SCWR hydrogen cogeneration system
(2015-12-01)SuperCritical Water-cooled Reactors (SCWRs) are one of six Generation-IV nuclear reactor concepts under development worldwide. SCWRs benefit from an increase in thermal efficiency due to the reactor coolant operating above ... -
An evaluation of the net breeding capability of heterogeneously-fuelled pressure-tube heavy water reactors with the thorium fuel cycle
(2015-12-01)The thorium fuel cycle is a promising future option for an alternative to uranium. The pressure tube heavy water reactor (PT-HWR) has for decades been considered capable of achieving net breeding on the thorium fuel cycle, ... -
