Operation Z machine: China’s next big weapon in the nuclear ‘arms race’ could create clean fuel – or deadly bombs
The Chinese military is building a test facility to simulate thermonuclear explosions on a much greater scale than comparable US centres It’s been described as a Chinese version of America’s “Z machine” – formally known as the Z Pulsed Power Facility – a giant wheel-like device developed by the United States to see how particles react under extreme radiation and magnetic pressure. Z machines have been used in the development of nuclear weapons, from conventional warheads to the pure fusion bomb – a hydrogen bomb that can in theory be made in any size, cost a fraction of today’s nuclear stockpile and burn “cleanly” without producing radioactive fallout. And for decades, the Z machine at Sandia National Laboratories in Albuquerque, New Mexico, has led the way in the field. But now Chinese researchers are trying to build a machine that will produce much more electricity to create much more extreme environments for testing weapons, allowing scientists to delve deeper into the nuclear unknown……….. Lei Yuan, a nuclear physicist at Peking University’s school of physics, said the project team should prepare for massive challenges. Lei said there had been costly failures in developing the technology in the US and Chinese scientists faced equal if not greater uncertainties because of their much more ambitious goals. For instance, fusion could produce a large number of fast flying neutrons that will weaken or damage critical components. While the equipment was durable, researchers had not yet been able to solve the neutron problem, Lei said. He warned the development of a pure fusion bomb would meant international nuclear weapons treaties would have to be rewritten. “But I don’t think we need to worry about this, not until we see a real new bomb. The technology is so difficult, it remains more fantasy than real threat.” https://www.scmp.com/news/china/science/article/2177652/operation-z-machine-chinas-next-big-weapon-nuclear-arms-race |
