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, ...
Comparative assessment of small modular reactor Passive Safety System design via integration of dynamic methods of analyses
(2019-12-01)
Integral Pressurized Water Reactor (iPWR) type SMR designs were studied featuring Passive Safety Systems (PSS) in all cases. As many as 11 current SMR designs use PSS to remove decay heat. Variations in PSS designs were ...
Planning and optimization of nuclear-renewable micro hybrid energy systems for off-grid applications
(2020-11-01)
Resilient operation of medium/large scale off-grid energy systems is a key challenge for energy crisis solutions, which requires continuous and sustainable energy resources. In this context, microreactors are incorporated ...
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 ...
Environmental impact of zebra mussel controls in nuclear power plants
(2020-04-01)
Industries that rely on the Great Lakes for cooling have battled the zebra mussel infestation for years. With increasing emphasis on environmental sustainability, decision-makers need to consider more than just monetary ...
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 ...
The effect of high dose rate on tissue equivalent proportional counter measurements in mixed neutron-gamma fields
(2010-04-01)
Tissue equivalent proportional counters (TEPCs) are commonly used for radiation monitoring in areas where a mixture of neutron and photon radiations may be present, such as those commonly encountered in nuclear power plants. ...
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 ...
Implementation of power electronics in nuclear power plants: DC electrical system conceptual design and its financial analysis
(2018-05-01)
A Power Electronic (PE) device is a semiconductor-based device which enable many advanced conversion of electricity which have been used widely in many industries. Due to the recent development in both circuit design and ...
