Investigation of Pressure-Tube and Calandria-Tube Deformation Following a Single Channel Blockage Event in ACR-700
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Advanced Nuclear Power Program, 2005-11)
The ACR-700 is an advanced pressure-tube (PT) reactor being developed by Atomic Energy of Canada Limited (AECL). As in conventional CANDU reactors, the PTs are horizontal. Each PT is surrounded by a calandria tube (CT), ...
AN EVOLUTIONARY FUEL ASSEMBLY DESIGN FOR HIGH POWER DENSITY BWRs
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Nuclear Fuel Cycle Program, 2007-07)
An evolutionary BWR fuel assembly design was studied as a means to increase the power
density of current and future BWR cores. The new assembly concept is based on replacing
four traditional assemblies and large water ...
Effects of Surface Parameters on Boiling Heat Transfer Phenomena
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Advanced Nuclear Power Program, 2011-06)
Nanofluids, engineered colloidal dispersions of nanoparticles in fluid, have been shown
to enhance pool and flow boiling CHF. The CHF enhancement was due to nanoparticle
deposited on the heater surface, which was verified ...
A Drop-In Concept for Deep Borehole Canister Emplacement
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Nuclear Fuel Cycle Program, 2011-06)
Disposal of high-level nuclear waste in deep boreholes drilled into crystalline bedrock (i.e.,
“granite”) is an interesting repository alternative of long standing. Work at MIT over the past
two decades, and more recently ...
Critical Heat Flux Enhancement via Surface Modification Using Colloidal Dispersions of Nanoparticles (Nanofluids)
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Advanced Nuclear Power Program, 2008-06)
Nanofluids are engineered colloidal dispersions of nanoparticles (1-100nm) in common fluids
(water, refrigerants, or ethanol…). Materials used for nanoparticles include chemically stable
metals (e.g., gold, silver, ...
Thermal-Hydraulic Analysis of Innovative Fuel Configurations for the Sodium Fast Reactor
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Advanced Nuclear Power Program, 2009-08)
The sodium fast reactor (SFR) is currently being reconsidered as an instrument for
actinide management throughout the world, thanks in part to international programs such
as the Generation-IV and especially the Global ...
Feasibility of Very Deep Borehole Disposal of US Nuclear Defense Wastes
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Nuclear Fuel Cycle Program, 2011-06)
This report analyzes the feasibility of emplacing DOE-owned defense nuclear waste from
weapons production into a permanent borehole repository drilled ~4 km into granite
basement rock. Two canister options were analyzed ...
