Specifics of forced-convection heat transfer in a vertical 7-element bundle cooled with upward flow of SuperCritical Water
(2020-08-17)
Current Generation II/III/III+ Nuclear Power Plants (NPPs) are no longer economically competitive partially due to low thermal efficiencies.
Six Generation IV NPP concepts were proposed having increased thermal efficiency, ...
Study of contaminants in plasmas during decommissioning processes
(2020-12-01)
With the intention of eventual development of on-site radionuclide capture technologies, methods to simulate radionuclide behaviour when contaminated components are subjected to plasma-based decommissioning processes are ...
Towards low dose retrospective dosimetry on shelled species
(2020-08-01)
This work investigates calcified tissues of shelled species for retrospective dosimetry using electron paramagnetic resonance (EPR) spectroscopy. To determine applicable samples for low dose studies, shells of crustacean ...
Local dose coefficients for radionuclide contamination in wounds
(2020-05-01)
The objective of this research is to create local dose coefficients for radionuclide contaminated wounds to accompany dose coefficients obtained by Oak Ridge Institute for Science and Education looking at whole body effects ...
Study of radio frequency inductively coupled thermal plasma torch (RF ICPT) for radioactive waste treatment: thermoplastics - polyethylene and polyvinyl chloride (PVC)
(2021-06-01)
Despite advancements in technology and many progresses made in effort for radioactive waste (RW) treatment and overall management, there is still no final and ever lasting solution. Among the many RW materials originating ...
A study on the impact of global replacement of fossil fuel based electricity generation, transportation and domestic heating with nuclear generated electricity using a modified VENSIM DICE model
(2021-08-01)
While much debated across current media, electricity generation using nuclear energy is proposed as one of the means of addressing the global negative impacts of climate change – notably ongoing accumulation of CO2 in the ...
Evaluation of the bubble spectrometer performance in space-like neutron fields
(2021-02-01)
The Space Bubble Detector Spectrometer (SBDS) consists of six bubble detectors each with a different neutron energy threshold. To characterize the spectrometer in a space-like neutron field, a series of experiments were ...
Study on heat transfer to supercritical water in application to SMRs
(2021-12-01)
The SuperSafe Reactor (SSR), a small modular reactor (SMR) concept with a supercritical water coolant, was subjected to a thermalhydraulic analysis and an economic analysis of its Levelized Unit of Energy Cost (LUEC). ...
Computational fluid dynamic investigations of flow through an aged CANDU pressure tube
(2021-08-01)
Single-phase, isothermal computational fluid dynamics simulations of twelve simplified CANDUTM 37M fuel bundles sitting in both as-received and aged pressure tubes were performed with Hydra in this work. The predicted ...
Development and demonstration of a high-performance Gaussian puff model for nuclear emergency training scenarios in unity game engine
(2021-08-01)
Prompt decision making and implementation of protective actions in the event of a nuclear or radiological emergency require detailed preparations and training. Computer models provide an avenue to simulate the presence of ...
