What happens to electrons during alpha decay? Is positron decay the same as gamma decay? What is gamma decay? Plutonium-239 alpha decay yields Does the number of neutrons change in alpha decay? Why does alpha decay have less energy than gamma decay?
Their solution was to create an implosion device consisting of a sphere of U-235 to act as the tamper and a plutonium-239 core surrounded by high explosives. When the bomb was detonated, it had a 23-kiloton yield with an efficiency of 17 percent. This is what happened: The explosives ...
Since the energy per fission from plutonium-239 and uranium-235 is about the same, the theoretical fuel value of fissile plutonium can be put at $5,600 per kilogram. Reactor-grade plutonium also contains non-fissile isotopes, reducing its value to about$4,400 per kilogram. What would happen...
As the name suggests, this involves fusing two atoms together to create a heavier atom, releasing energy in the process. There are several advantages of this, including the production of more energy, the non-reliance on radioactive elements such as plutonium that need careful handling, and the...
How much time is required for a 6.25-mg sample of radioactive C to decay to 0.75 mg if it has a half-life of 27.8 days? If a nuclide has a half-life of 100 seconds, what is the corresponding mean lifetime? What is the half-life of plutonium? What is the half-life of uranium?
Under these circumstances the neutronic value of U-233 will tend to be high relative to that of Pu-239, particularly if the thorium fuel cycle is well established by then. Then transmuter reactors burning plutonium and producing U-233 can realize a very substantial profit from the fuel ...

Pellets of plutonium dioxide release heat through natural decay. This heat is converted into electricity using a series of thermocouples. Although the power output isn't very strong, it powers the electronics and instruments on board the Voyagers for a very long time. Power isn't expected to ...
It wasn't easy to build. Early bomb designers faced several problems, particularly how to control and direct the shock wave uniformly across the sphere. Their solution was to create an implosion device consisting of a sphere of U-235 to act as the tamper and a plutonium-239 core surrounded...
(HFIR), a DOE Office of Science user facility at ORNL, will provide PROSPECT with its neutrinos. Commercial nuclear reactors use a variety of uranium and plutonium fuels with different combinations of isotopes. This results in a broad spectrum of neutrino energies. That makes it difficult to ...
