Characterization of the Neutron Irradiation System for use in the Low-Dose-Rate Irradiation Facility at Sandia National Laboratories
… the neutron irradiation system consisting of americium 241 beryllium (241AmBe) neutron sources placed in a polyethylene shielding for use at Sandia National Laboratories (SNL) Low Dose Rate Irradiation Facility (LDRIF). With a total activity of 0.3 TBq (9 Ci), the source consisted of three …

Management of the UK plutonium stockpile using thorium fuelled Light Water Reactors
… feasibility of this approach. The build-up of americium-241 from decay of Pu-241 leads to increased fissile feed requirements which, in the case of U-Pu MOX fuels causes the Void Coefficient (VC) to become positive under transient conditions for a stockpile averaged Pu vector from the year 2055 …

Determination of actinide elements in environmental samples by ICP-MS
… actinide elements neptunium, plutonium and americium, resulted in the successful determination of 239Pu and 237Np in biological reference materials. Detection limits were 700, 850, and 600 attograms (ag) for 237Np, 233Pu, and 241Am, respectively, for a 0.5 ml sample injection, and better …
