Separate effects of surface roughness, wettability and porosity on boiling heat transfer and critical heat flux and optimization of boiling surfaces
(Massachusetts Institute of Technology, 2012)
The separate effects of surface wettability, porosity, and roughness on critical heat flux (CHF) and heat transfer coefficient (HTC) were examined using carefully-engineered surfaces. All test surfaces were prepared on ...
Nuclear tanker producing liquid fuels from air and water
(Massachusetts Institute of Technology, 2011)
Emerging technologies in CO₂ air capture, high temperature electrolysis, microchannel catalytic conversion, and Generation IV reactor plant systems have the potential to create a shipboard liquid fuel production system ...
Controlling CRUD vapor chimney formation in LWRs through surface modification
(Massachusetts Institute of Technology, 2014)
Fouling has been a persistent problem for fluid-solid interfaces, varying from heat exchangers to ship hulls. In nuclear power plants, buildup of CRUD can accelerate corrosion, increase pressure drops, cause axial power ...
Coupled fluid structure simulations for application to grid-to-rod fretting
(Massachusetts Institute of Technology, 2014)
Grid-to-rod fretting (GTRF) has been the major cause of fuel leakage in Pressurized Water Reactors (PWRs) for the past ten years. It is responsible for over 70% of the fuel leaking in PWRs in the United States. The Consortium ...
CFD in support of development and optimization of the MIT LEU fuel element design
(Massachusetts Institute of Technology, 2014)
The effect of lateral power distribution of the MITR LEU fuel design was analyzed using Computational Fluid Dynamics. Coupled conduction and convective heat transfer were modeled for uniform and non-uniform lateral power ...
Nuclear renewable oil shale hybrid energy systems : configuration, performance, and development pathways
(Massachusetts Institute of Technology, 2015)
Nuclear Renewable Oil Shale Systems (NROSS) are a class of large Hybrid Energy Systems in which nuclear reactors provide the primary energy used to produce shale oil from kerogen deposits and also provide flexible, ...
Effect of residual stress on the life prediction of dry storage canisters for used nuclear fuel
(Massachusetts Institute of Technology, 2013)
Used nuclear fuel dry storage canisters will likely be tasked with holding used nuclear fuel for a period longer than originally intended. Originally designed for 20 years, the storage time will likely approach 100 years. ...
Ultracompact superconducting isochronous cyclotron production of ¹³N for positron emission tomography applications
(Massachusetts Institute of Technology, 2013)
Testing was performed on a data acquisition (DAQ) system that was built specifically to characterize a new ultracompact superconducting isochronous cyclotron (USIC) at MIT. A production model of Nitrogen-13 was validated ...
Materials testing and development of functionally graded composite fuel cladding and piping for the Lead-Bismuth cooled nuclear reactor
(Massachusetts Institute of Technology, 2013)
This study has extended the development of an exciting technology which promises to enable the Pb-Bi eutectic cooled reactors to operate at temperatures up to 650-700°C. This new technology is a functionally graded composite ...
Two-Color interferometry as a fluctuation diagnostic on Alcator C-Mod
(Massachusetts Institute of Technology, 2013)
The two-color interferometer diagnostic on Alcator C-Mod has been upgraded to measure line-integrated electron density fluctuations for turbulence and transport studies. Heterodyne signals from ten vertical-viewing CO2 ...
