IAEA safeguards for light water power reactors (LWRs) allow inspectors to provide the international community with a high degree of confidence that nuclear material located at the reactor site has not been diverted to nuclear weapons, other nuclear explosive devices, or purposes unknown. IAEA safeguards for sealed, transportable small modular reactors (SMR), however, are not as well-developed...
New trend in development of nuclear energy use is small modular reactors (SMR) as energy source for remote regions. Special directions in those trends take innovation projects of transportable nuclear power plants (TNPP) with factory fueled and sealed core, having resources for exploitation for 10 years without reloading and without storage for spent nuclear fuel at the site. Such nuclear...
Several thorium fuel cycle variants are currently being actively pursued by the global nuclear energy community. These variants have short-, medium-, and long-term deployment pathways in a variety of reactor types, including thorium-fueled molten salt reactors. Those pathways in turn give rise to a variety of fuel designs, fuel cycle facilities, and nuclear material processing requirements....
The Generation Four International Forum (GIF) formed a proliferation resistance and physical protection (PR&PP;) Working Group (PRPPWG) to develop a methodology to evaluate the six GIF nuclear energy systems concepts.
The PRPPWG developed the methodology through a series of development and demonstration case studies, using a hypothetical “Example Sodium Fast Reactor” (ESFR). The ESFR...
Research reactors with thermal power of 25 MW or less are assumed not able to produce 1 SQ of Pu or U-233 per annum. Binford’s correlation is a rough estimate for the capability of any Uranium-fueled thermal reactor to produce Pu. The quality of Pu-239 varies with fresh fuel type, neutron flux and irradiation time. An increase in irradiation time results in the build-up of Pu-240.
