Nuclear Weapons

Who’s got Nuclear Weapons ? The Effects of Nuclear Weapons Trident is Britain’s nuclear weapon system. It consists of four nuclear powered, nuclear-armed submarines, one of which is on patrol, under the seas, at all times. Each Trident submarine carries up to 48 nuclear warheads, each of which can be sent to a different target. Each warhead has an explosive power of up to 100 kilotons, the equivalent of 100,000 tons of conventional high explosive. This is 8 times the power of the atomic bomb that destroyed Hiroshima in 1945, killing an estimated 140,000 people. Trident and its Replacement

The Treaty on the Prohibition of Nuclear Weapons

This new United Nations treaty prohibits states from developing, testing, producing, manufacturing, transferring, possessing, stockpiling, using or threatening to use nuclear weapons, or allowing another state’s nuclear weapons to be stationed or deployed on their territory. The treaty also prohibits states from assisting, encouraging or inducing anyone to engage in any of those activities. Britain has not signed this treaty. The Treaty on the Prohibition of Nuclear Weapons The Senedd voted to support the TPNW as part of a resolution on Ukraine.

Nuclear power

The chain reaction inside a nuclear reactor core produces plutonium, which can be separated out by reprocessing the spent fuel to make weapons of mass destruction. The UK government’s Atoms for Peace project in the 1950s was actually a secret plan to produce plutonium for the first nuclear bombs. It has now been confirmed that both Trawsfynydd and Wylfa A were also used for this purpose. From the start, military and ‘civil’ nuclear power were two sides of the same coin.
