A promising source of energy are nuclear fusion reactors (more stable and with less radioactive products than fission reactors). Their basic reaction is the fusion of two forms of heavy hydrogen into helium and a neutron: d + t → 4He + n. The deuteron (d) consists of a neutron (n) and a proton (p) bound by 2.2 MeV , the triton (t) of 2 n’s and a p bound by 8.5 MeV , and 4He of 2 n’s and 2 p’s bound by 27.4 MeV . How much deuterium (in kg) is burnt in a 100 MW fusion reactor in one month (assuming 50% energy efficiency of the reactor)?

Nuclear fission and electrical energy Electrical energy currently produced by nuclear reactors is derived from the decay of 235 92U, through a process known as nuclear fission, whereby a slow-moving neutron is captured by the 235 92U nucleus, creating 236 92U. The uranium nucleus 236 92U is very unstable, and it will immediately decay into two lighter elements and release neutrons. Some of the neutrons will go on to destabilize other nuclei, creating a chain reaction. During fission reactions the...

Which type of nuclear decay is the following radioactive isotope likely to undergo? All known stable isotopes are shown on the graph. The points form what is know as the "belt of stability". If a radioactive isotope is above the belt of stability, think about what type of decay would decrease its N/Z ratio. If an unstable isotope is below the belt of stability, think about what type of decay would increase its N/Z ratio. If a radioactive isotope is...
