Graphite bomb BLU-114/B. A graphite bomb is intended to be a non-lethal weapon used to disable an electrical grid.The bomb works by spreading a dense cloud of extremely fine, chemically treated carbon filaments over air-insulated high voltage installations like transformers and power lines, causing short-circuits and subsequent disruption of the electricity supply in an area, a region or even ...
Total weight of nuclear material and bomb was 98.8 - 100.2 kg Hiroshima's "Little Boy" gravity bomb: 13–18 54–75 Gun type uranium-235 fission bomb (the first of the two nuclear weapons that have been used in warfare). 64 kg of Uranium-235, about 1.38% of the uranium fissioned Nagasaki's "Fat Man" gravity bomb 19–23 79–96

There are about 179–264 fuel rods per fuel bundle and about 121 to 193 fuel bundles are loaded into a reactor core. Generally, the fuel bundles consist of fuel rods bundled 14×14 to 17×17. PWR fuel bundles are about 4 m (13 ft) long. In PWR fuel bundles, control rods are inserted through the top directly into the fuel bundle.
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
Caesium-137 (137. 55Cs. ), cesium-137 (US), [7] or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. Trace quantities also originate from spontaneous fission of uranium-238.
The highest levels found (of Pu-239 and Pu-240 combined) were 15 becquerels per square meters in Fukushima prefecture and 9.4 Bq in Ibaraki prefecture, compared to a global average of 0.4 to 3.7 Bq/kg from atomic bomb tests.
The presence of the isotope plutonium-240 in a sample limits its nuclear bomb potential, as 240 Pu has a relatively high spontaneous fission rate (~440 fissions per second per gram; over 1,000 neutrons per second per gram), [20] raising the background neutron levels and thus increasing the risk of predetonation.
