Also, because the packages are cooler, they can also be placed closer together, increasing repository capacity.8 Clearly, IFRs can be part of a much longer-term strategy for U.S. nuclear energy, since they provide a cheap, efficient way to dispose of waste that is proliferation resistant.
It was found that the proposed core, which provides twice the flux per unit core power compared to similar natural uranium fueled, light water cooled, heavy water moderated and graphite reflected research reactors, NRX/CIR, is proliferation resistant almost by a factor of 2 as compared to NRX/CIR.
That agreement called for North Korea to give up its nuclear program in exchange for two light-water nuclear reactors (which are proliferation-resistant) for electric power generation.
In the paper we assume that plutonium with sufficiently high content of the Pu-238 isotope (about 6% or more) and americium from spent nuclear fuel are proliferation-resistant.
The mature, quiescent MCF10A structures are exceedingly proliferation resistant, being able to prevent Myc-induced cell cycle re-entry.
Because no plutonium is separated in the process, the fuel can be considered proliferation resistant.
Therefore reactor-grade plutonium may not be sufficiently proliferation resistant against nuclear terrorism.
Also the waste is nearly proliferation resistant because of the low concentrations of plutonium comprised mainly of poor material for weapons.
In exchange, a consortium, the Korean Peninsula Energy Development Organization, was created to build replacement reactors for North Korea based on technology that was more proliferation-resistant.
Unfortunately, reactor-grade Pu contains only 2.7% 238Pu and is thus not sufficiently proliferation resistant in this respect.
Both probabilistic and deterministic PR measures are calculated using a software tool that implements the proposed approach and can be used to quantitatively compare proliferation resistant characteristics of different scenarios for a given NES, according to the computed PR measures.
