Indonesia recently announced plans for 12 nuclear reactors, but these plans were quickly postponed until 2020. Alternatively, many of these radioisotopes can be produced in special machines called accelerators or cyclotrons, which do not require the use of uranium and do not involve the generation of high-level nuclear waste. Nuclear reactors also serve to drive the propulsion units of nuclear submarines. In addition, special military reactors are used to produce most of the nuclear explosive materials used in nuclear weapons. Nuclear power cells are commonly used in space technology to power satelites also.
Nuclear reactors fuelled with uranium automatically produce plutonium as a byproduct.
If that plutonium is chemically separated from the rest of the radioactive garbage in the spent reactor fuel, it can be used as a nuclear explosive. So, the spread of nuclear power around the world gives more and more countries the option of producing nuclear weapons at some future time. In 1974, India exploded a bomb that was made from plutonium produced in a reactor given to the Indian government as a gift by the Canadian government. However, it is well established that the sale of uranium to the CDA in the 50s and 60s resulted in the uranium being used to produce plutonium for military purposes. Any country purchasing Australian uranium must promise not to use it or the byproduct plutonium for bombs.
