1. A comparison of the measured spectrum with that expected for antineutrinos issuing from the fission reactions in the reactor's core reveals whether the antineutrinos have changed in any way en route to the detector; muon- or tau-antineutrinos would not produce inverse beta decays.
2. The greatest importance of the Oklo reactors is that they are still there - after almost 2000 million years we can still find the fission products and demonstrate what happened.
3. Thus, one could almost describe the period since the Roman Empire as one of alternating fusion and fission, each phase extending the geographical reach of the system more and more widely.
4. Some uranium, lead and fission products were lost some 722 30 million years ago - Nagy et al calculated the date from the remaining U/Pb isotopes.
5. Plutonium is a unique and inevitable by-product of nuclear fission.
6. So there was a chance that fusion, which would derive its energy from deuterium, an isotope of hydrogen and a constituent of ordinary water, could come along and render fission redundant.
7. Flowers concluded with a much-quoted dictum: "There should be no commitment to a large programme of nuclear fission power until it has been demonstrated beyond reasonable doubt that a method exists to ensure the safe containment of long-lived, highly radioactive waste for the indefinite future."
8. Nuclear fission chain reactions began in patches of ore with concentrations of 25-;60 per cent U, and lasted for 10sup5; -;10sup6; years until too little fissile material remained.
9. What was clear, however, was that he was extremely intelligent, and quickly got to grips with the complex technicalities of nuclear fission and its consequences.
10. Eventually they may take over a small group when the large parent troop undergoes fission as increasing size produces social instability.
11. Controlled fusion has fewer obvious negative aspects than fission.
12. Start to phase out nuclear fission power stations , which are prohibitively expensive and potentially hazardous.
13. In the mid-1950's nuclear fission had still to be turned into a commercial power source.
