The US has an excellent safety record with its nuclear-powered fleet although early Russian subs suffered a few accidents which caused 20 servicemen to die from radiation exposure between 19.ДЄt the end of their 20-year lifetimes, the contaminated parts of nuclear reactors need to be disposed deep underground in special waste storage cells.ДЄnti-nuclear campaigners say any leaks of radioactive waste could lead to an environmental disaster. The nuclear reactors are shielded from the rest of the submarine in a separate section to protect the crew from dangerous radiation. 'And we will continue to meet all our nuclear non-proliferation obligations.' Are they safe? 'But let me be clear, Australia is not seeking to acquire nuclear weapons or establish a civil nuclear capability,' he said. Mr Morrison also said the Australia has no plans to build nuclear power stations which are widely used around the world. Scott Morrison made it clear that the nuclear-power submarines will not have nuclear missiles on board.ДЄustralia has never produced nuclear weapons and signed theВ Treaty on the Non-Proliferation of Nuclear Weapons in 1973 which prevents non-nuclear states which don't already have them from developing nuclear weapons. 'They are going to be much, much more capable in the large, expansive ocean that is Australia has to deal with,' he told the ABC. Zack Cooper, a senior fellow with the American Enterprise Institute, said nuclear submarines would hugely boost Australia's military capability. 'They will allow us to sustain and to improve deterrence across the Indo-Pacific.' They are now also in use by Russia, France, the United Kingdom, China, and India.ДЄ senior US defence official told reporters in Washington DC:В 'This will give Australia the capability for their submarines to basically deploy for a longer period, they're quieter, they're much more capable. The first nuclear submarines were put to sea by the United States in the 1950s. The boats are also very quiet, making it harder for enemies to detect them and can travel at top speed - about 40kmh - for longer than diesel-powered subs. They can run for about 20 years before needing to refuel, meaning food supplies are the only limit on time at sea. Nuclear submarines are powered by nuclear reactors which produce heat that creates high-pressured steam to spin turbines and power the boat's propeller. Assigning submarines to patrol the South China Sea will be Britain's most assertive move yet against Beijing.ДЄccording to reports in Australia, Royal Navy submarines would be based at PerthВ on the country's western coast and Australian submariners would be incorporated into British crews to improve their skills.Д«asing the Royal Navy boats thousands of miles from UK shores is part of the AUKUS (Australia, United Kingdom and United States) security alliance.ДЄUKUS was set up last year primarily to confront Chinese military expansionism in the Indo-Pacific. The dramatic decision could see UK subs based in Australia until 2040, operating within striking distance of China.ДЄdmiral Sir Tony Radakin, the head of the Armed Forces, will agree the arrangement at a naval conference in Sydney next week. The revelation comes as Britain prepares to send a fleet ofВ nuclear submarines to the Pacific in a decisive move to thwart Chinese aggression in the region. The AUKUS deal was signed by the Morrison government and has the backing of Anthony Albanese (pictured) Guo says the submarine's high speed and endurance will also allow it to inspect distant waters and track potential targets. This would leave the radioactive material outside any blast radius. The small reactor would be 'ejected' to the seabed shortly before the torpedo strikes its target - with an on-board battery pushing it to its target. They have also insisted it is notВ a 'dirty bomb' or a nuclear weapon in disguise.

Now, Chinese researchers claim they can deliver their version of the weapon within 10 years. The weapon is designed to trigger a tsunami off any coastal city with a nuclear warhead. Moscow claims it is unstoppable by current nuclear defences, and could be used to destroy coastal cities or blow up aircraft carriers and their battle groups. Poseidon is a Russian nuclear weapon that is a blend of torpedo and drone.
