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 ...
Improving x-ray operator performance using virtual environments
(2021-08-01)
There are significant limitations in the training for x-ray operators under current regulatory and operational constraints. Advances in technology now allow for the creation of realistic virtual reality environments, which, ...
Characterization of PVA-Borax-fructose gel for the capture of radioactive wastes generated during nuclear decommissioning activities
(2021-05-01)
With the long-term objective of using polymer gels for the capture of solid, liquid and gaseous waste generated from decommissioning works, characterization of gel properties as well as the properties of the individual ...
Analysis and optimal planning of nuclear-renewable hybrid energy systems for ships
(2021-06-01)
Ocean-going ships are one of the sources of global GHG emissions. Several actions are being taken to reduce the GHG emissions from maritime vessels, and integration of Renewable Energy Sources (RESs) is one of them. Due ...
Detector integration of severe accident management instrumentation for robotic applications at nuclear reactor facilities
(2021-08-01)
In the aftermath of a nuclear accident, robots can be used to monitor and assess radiological contamination, preventing harmful exposure to plant personnel. In this work, several detectors were evaluated to be supplemented ...
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 ...
