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 ...
Regional Examples of Geological Settings for Nuclear Waste Disposal in Deep Boreholes
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Nuclear Fuel Cycle Program, 2010-01)
This report develops and exercises broad-area site selection criteria for deep boreholes suitable for disposal of spent nuclear fuel and/or its separated constituents. Three candidates are examined: a regional site in the ...
Conceptual Design of an Annular-Fueled Superheat Boiling Water Reactor
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Advanced Nuclear Power Program, 2010-10)
The conceptual design of an annular-fueled superheat boiling water reactor (ASBWR) is
outlined. The proposed design, ASBWR, combines the boiler and superheater regions into
one fuel assembly. This ensures good neutron ...
Design of a Functionally Graded Composite for Service in High Temperature Lead and Lead-Bismuth Cooled Nuclear Reactors
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Advanced Nuclear Power Program, 2010-10)
A material that resists lead-bismuth eutectic (LBE) attack and retains its strength at 700°C
would be an enabling technology for LBE-cooled reactors. No single alloy currently exists
that can economically meet the required ...
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 ...
A Framework for Performance Assessment and Licensing of Deep Borehole Repositories
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Nuclear Fuel Cycle Program, 2010-03)
This is the initial progress report under a Sandia-MIT contract dealing with development of
engineering and geological siting criteria for deep borehole disposal of spent nuclear fuel or
its separated constituents. ...
HLW Deep Borehole Design and Assessment: Notes on Technical Performance
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Nuclear Fuel Cycle Program, 2010-04-01)
This is a progress report covering work through mid-April 2010 under a Sandia-MIT
contract dealing with design and siting/licensing criteria for deep borehole disposal of spent
nuclear fuel or its separated constituents.
It ...
Comparison Between Air and Helium for Use as Working Fluids in the Energy-Conversion Cycle of the MPBR
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. Advanced Nuclear Power Program, 2011-02)
A comparison between air and helium for use as working fluids in the energy-conversion cycle of the MPBR is presented. To date, helium has been selected in the MPBR indirect-cycle working reference design. Air open- and ...
Estimate of Radiation Release from MIT Reactor with Low Enriched Uranium (LEU) Core During Maximum Hypothetical Accident
(Massachusetts Institute of Technology. Center for Advanced Nuclear Energy Systems. MIT Reactor Redesign Program, 2011-06-01)
In accordance with a 1986 NRC ruling, the MIT Research Reactor (MITR) is planning on
converting from the use of highly enriched uranium (HEU) to low enriched uranium
(LEU) for fuel. A component of the conversion analysis ...
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 ...
