A significant amount of interest has been
aroused recently concerning the advancement of the
current pressurized water reactor core designs with
a special emphasis towards improving the conversion
characteristics of these reactors. Most reports
have been divided into two camps; those that deal
with the neutronic aspects and those that...
The Very High Temperature Reactor (VHTR) design was one of six designs chosen
for development under the Generation IV initiative. Thermal mixing of the coolant at
the exit of the reactor has been a common concern for VHTR reactor designs.
Thermal mixing processes are commonly investigated through the use of...
The Multi-Application Small Light Water Reactor (MASLWR) is a small natural circulation pressurized light water reactor design that was developed by Oregon State University (OSU) and Idaho National Engineering and Environmental Laboratory (INEEL) under the Nuclear Energy Research Initiative (NERI) program to address the growing demand for energy and electricity....
The United States nuclear industry is under
significant public pressure to close the nuclear fuel
cycle. Closing the fuel cycle will require that nuclear
waste, fission products and transuranics, except plutonium
(actinides), be disposed of by permanent burial. The
actinides can be buried with the fission products, but this
will...
A continuous process for the production of ceramic materials has been studied.
This method reacted metal and oxidizer in a diffusionally controlled process,
demonstrated by reacting a magnesium particle stream and hot water vapor. Many small
rich hydrogen/air diffusion flames provide an atmosphere of hot water vapor, hydrogen,
and nitrogen...
The Department of Nuclear Engineering and Radiation Health Physics (NE/RHP) at Oregon State University (OSU) has been developing an innovative modular reactor plant concept since being initiated with a Department of Energy (DoE) grant in 1999.
This concept, the Multi-Application Small Light Water Reactor (MASLWR), is an integral pressurized water...
In order to address the energy needs of developing countries and remote communities, Oregon State University has proposed the Multi-Application Small Light Water Reactor (MASLWR) design. In order to achieve five years of operation without refueling, use of 8% enriched fuel is necessary.
This dissertation is focused on core design...
Some of the next generation of small modular reactors have been designed with helically coiled steam generators integrated into the reactor vessel to enhance natural circulation. According to the developers of TASS/SMR, a one-dimensional thermal hydraulic code written to model the Korean Atomic Energy Research Institute's SMART reactor, the Žukauskas...
Preliminary nuclear design studies have been completed on ten
configurations of nuclear reactors for low power (1-30 kWe) space
applications utilizing thermionic energy conversion. Additional design
studies have been conducted on the TRICE multimegawatt in-core
thermionic reactor configuration. In each of the cases, a reactor
configuration has been determined which...
Dry reforming of methane to syngas using CO2 was performed in a solar-driven milli-scale reactor, which converts solar energy to chemical energy. The process aims to upgrade the energy content of the feed stream using sustainable energy. The effect of mean residence time, temperature and CO2:CH4 ratio on conversion and...
