Plutonium recovered from LWR spent fuel, while not weapons grade, can be used to produce nuclear weapons at all levels of sophistication, [25] though in simple designs it may produce only a fizzle yield. [26] Weapons made with reactor-grade plutonium would require special cooling to keep them in storage and ready for use. [27]
Allegations that Silkwood's exposure to plutonium-239 was a deliberate act of radiation poisoning are fueled by the fact that she was in possession of potentially compromising evidence that linked Kerr-McGee with egregious safety violations, encompassing unsafe workplace conditions at the plant, faulty manufacture of fuel rod components that ...
Plutonium–gallium–cobalt alloy (PuCoGa 5) is an unconventional superconductor, showing superconductivity below 18.5 K, an order of magnitude higher than the highest between heavy fermion systems, and has large critical current. [46] [50] Plutonium–zirconium alloy can be used as nuclear fuel. [51]
What to eat instead of deli meat If you're really craving a deli sandwich, Cassetty advises buying a rotisserie chicken or freshly roasted turkey as healthier protein sources compared to packaged ...
Sep. 6—Work continues at the Savannah River Site to transform the Mixed-Oxide Fuel Fabrication Facility into a plutonium pit production facility. The South Carolina Department of Health and ...
Isotopes of plutonium, americium, and uranium were detected, with the highest measured activity being 0.0125 pCi/g of uranium-233, 234. The study found that the increased cancer risk to an individual who ate 28 kilograms (62 lb) of Rocky Flats deer meat per year for 70 years was at most 1 in 210,000.
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...
The pits of the first nuclear weapons were solid, with an urchin neutron initiator in their center. The Gadget and Fat Man used pits made of 6.2 kg of solid hot pressed plutonium-gallium alloy (at 400 °C and 200 MPa in steel dies – 750 °F and 29,000 psi) half-spheres of 9.2 cm (3.6 in) diameter, with a 2.5 cm (1 in) internal cavity for the initiator.
