Environmental behavior of hafnium : the impact on the disposition of weapons-grade plutonium
… as a neutron poison for the disposition of weapons-grade plutonium in Yucca Mountain. The hydrolysis of hafnium was investigated by potentiometric titration in solutions of varying ionic strength to determine the stability constants for the first four monomeric hydrolysis products. The …

Imaging the ionization track of alpha recoils for the directional detection of weapons grade plutonium
Since the dawn of the nuclear weapons era, political, military, and scientific leaders around the world have been working to contain the proliferation of Special Nuclear Material and explosively fissile material. This paper describes the construction of a prototype, directional, fast neutron …

Monitoring under the Plutonium Management and Disposition Agreement : the prospects of antineutrino detection as an IAEA verification metric for the disposition of weapons-grade plutonium in the United States
… nuclear warheads. Although all Soviet-era weapons were eventually acquired by Russia, concerns about the excessively large weapons stockpiles of the United States and Russia, combined with the goal of nuclear disarmament, led to the Plutonium Management and Disposition Agreement (PMDA). …

Application of advanced fuel concepts for use in innovative pressurized water reactors
… of these knowledge gaps: (1) the disposition of weapons-grade plutonium in thorium and silicon carbide cladding, (2) economics of accident tolerant fuel (ATF) claddings and (3) breeding of plutonium in uranium nitride fuel. Burning weapons-grade plutonium in a standard pressurized water reactor …

Monte Carlo simulations of a physical cryptographic warhead verification protocol using nuclear resonance fluorescence
… for authenticity without revealing any sensitive weapons design information to international inspectors. Recent efforts have investigated physical cryptographic verification protocols that attempt to solve this treaty verification problem by using physics processes rather than electronics to …

Advanced nodal methods for MOX fuel analysis
… being considered for the disposal of surplus weapons grade plutonium is to bum the plutonium as mixed oxide fuel (MOX) in commercial light water reactors (LWR's). The introduction of MOX fuel into LWR's poses several challenges for the reactor analyst. The spectrum difference between MOX and …

Nuclear warhead monitoring : a study of photon emissions from fission neutron interactions with high explosives as a tool in arms control verification
… surrogate materials to represent the warhead's weapons-grade plutonium and HE. The experiment did not show the expected signals. This motivated a simulation of the mock-up experiment using the radiation transport code MCNP6 to help understand the observed results. The experimental and simulation …

Proliferation Resistance of Utilizing Enriched Reprocessed Uranium
… in the ERU-based LWR fuel. Besides denaturing plutonium with Pu-238, reprocessed U (RepU) holds advantage over natural uranium in terms of discouraging production of highly enriched uranium (HEU). The presence of minor uranium isotopes U-232, U-234, and U-236 in the discharged fuel complicates …
