Proliferation Resistance of Utilizing Enriched Reprocessed Uranium
… used nuclear fuel being the acquisition path for Pu and U by the proliferating states, the roles of intrinsic and extrinsic barriers to proliferation through this path need a deeper analysis. Denaturing of a fissile material, such as U or Pu, is one of the intrinsic barriers that renders the …

Alpha-radioactive isotopes in the marine environment.
… by radiochemistry and alpha-spectrometry for Pu-239, 240. Many of these organisms were also analysed for Pu-238, Po-210 and - those isotopes of thorium and uranium that are alpha-emitters. In some samples an estimate of the Ra-226 content was also made. The Pu-239 concentrations are compared …

The history of plutonium and cesium-137 contamination of the Ob River delta sediments
… of the particle reactive isotopes Cs-137, Pu-239,240, and Pu-238 with depth in sediments. To preserve a temporal record, the sediments need to be deposited more or less continuously and to not be subject to mixing. Meeting these criteria led to a focus on sampling in the shallow "sor" and …

Design strategies for optimizing high burnup fuel in pressurized water reactors
… fuel storage capacity, increased core power output and the search for increased proliferation resistance, achieving burnup in the 70 to 100 MWd/kg range has attracted considerable attention. However the implications of this initiative have not been fully explored; hence this work defines the …
