At the end of 1938 Otto Hahn and Fritz Strassmann in Berlin showed that the new lighter elements were barium and others which were about half the mass of uranium, thereby demonstrating that atomic fission had occurred.

What was the Russian nuclear physics?

Russian nuclear physics predates the Bolshevik Revolution by more than a decade. Work on radioactive minerals found in central Asia began in 1900 and the St Petersburg Academy of Sciences began a large-scale investigation in 1909. The 1917 Revolution gave a boost to scientific research and over 10 physics institutes were established in major Russian towns, particularly St Petersburg, in the years which followed. In the 1920s and early 1930s many prominent Russian physicists worked abroad, encouraged by the new regime initially as the best way to raise the level of expertise quickly. These included Kirill Sinelnikov, Pyotr Kapitsa and Vladimir Vernadsky.

Which isotope was most likely to have fission?

Bohr soon proposed that fission was much more likely to occur in the uranium-235 isotope than in U-238 and that fission would occur more effectively with slow-moving neutrons than with fast neutrons. The latter point was confirmed by Szilard and Fermi, who proposed using a 'moderator' to slow down the emitted neutrons.

How did the 1970s affect nuclear power?

In the early 1970s, the increased public hostility to nuclear power in the United States lead the United States Atomic Energy Commission and later the Nuclear Regulatory Commission to lengthen the license procurement process, tighten engineering regulations and increase the requirements for safety equipment. Together with relatively minor percentage increases in the total quantity of steel, piping, cabling and concrete per unit of installed nameplate capacity, the more notable changes to the regulatory open public hearing -response cycle for the granting of construction licenses, had the effect of what was once an initial 16 months for project initiation to the pouring of first concrete in 1967, escalating to 32 months in 1972 and finally 54 months in 1980, which ultimately, quadrupled the price of power reactors.

Nuclear power generation had the biggest ever fall year-on-year in 2012, with nuclear power plants globally producing 2,346 TWh of electricity, a drop of 7% from 2011. This was caused primarily by the majority of Japanese reactors remaining offline that year and the permanent closure of eight reactors in Germany.

The total global installed nuclear capacity initially rose relatively quickly, rising from less than 1 gigawatt (GW) in 1960 to 100 GW in the late 1970s, and 300 GW in the late 1980s. Since the late 1980s worldwide capacity has risen much more slowly, reaching 366 GW in 2005.

What did Rutherford discover?

In 1932, physicist Ernest Rutherford discovered that when lithium atoms were "split" by protons from a proton accelerator, immense amounts of energy were released in accordance with the principle of mass–energy equivalence. However, he and other nuclear physics pioneers Niels Bohr and Albert Einstein believed harnessing the power of the atom for practical purposes anytime in the near future was unlikely. The same year, Rutherford's doctoral student James Chadwick discovered the neutron. Experiments bombarding materials with neutrons led Frédéric and Irène Joliot-Curie to discover induced radioactivity in 1934, which allowed the creation of radium -like elements. Further work by Enrico Fermi in the 1930s focused on using slow neutrons to increase the effectiveness of induced radioactivity. Experiments bombarding uranium with neutrons led Fermi to believe he had created a new transuranic element, which was dubbed hesperium.

Nuclear fusion, on the other hand, is where two or more nuclei fuse together. This produces an enormous amount of binding energy - it's the process of fusion that that powers active stars. These immensely powerful processes provide the science behind the technology of nuclear weapons. The atomic bombing of Nagasaki.
