Some 60 people from the police and Japan Coast Guard participated in the exercise at the Ikata nuclear power plant, which simulated a drone launched from a boat planting a makeshift explosive device on the premises of reactor 3. Officials of Shikoku Electric Power Co., which runs the plant, and members of the bomb disposal unit in the Ehime Prefectural Police also took part. "We took into account the serious situation regarding terrorism in conducting this drill, and I think it is important to prepare for the unpredictable," said Hideto Murase, the local security chief of the Ehime Prefectural Police. Shikoku Electric plans to finish building by March 2020 a facility that is capable of withstanding major terror attacks, such as those involving intentional aircraft crashes, and preventing the release of radioactive materials.
When he first reported to MIT's Nuclear Reactor Laboratory (NRL) as an undergraduate in 2002, David Carpenter anticipated a challenging research opportunity. After 15 years at the NRL conducting research and earning degrees in nuclear science and engineering, Carpenter's appetite for scientific discovery remains sharp, as does his commitment to improving both the performance and safety of current and next-generation nuclear reactors. "The design is intrinsically safe because the fuel doesn't melt, and the salt can withstand high temperatures without requiring thick, pressurized containment buildings," he says. The challenges to designing this new kind of reactor involve finding optimal construction materials, since super-hot radioactive salt is highly corrosive.
To find out more, we talked to Dr Rustam Stolkin, Royal Society Industry Fellow for Nuclear Robotics, Professor of Robotics at the University of Birmingham, and Director at A.R.M Robotics Ltd, about his work combining machine learning and robotics to create practical solutions to nuclear problems. My work focuses on developing advanced robotics technologies for nuclear decommissioning, demolishing legacy nuclear sites, and safely packaging, storing and monitoring any radiological or contaminated materials. They have an enormous diversity of scenes, materials, and objects that nuclear decommissioning robots must interact with in complex ways, such as by grasping and cutting objects. Using robots also reduces "secondary nuclear waste"; for every one container filled with actual primary nuclear waste, more than ten containers become filled with contaminated plastic suits, respirators, rubber gloves, and other "secondary waste" from human entries.
In studying the Three Mile Island nuclear accident, Yale sociologist Charles Perrow concluded that conventional engineering approaches to ensuring safety – building-in more warnings and safeguards – will always fail in the face of increasing system complexity. He called the nuclear accident a "normal accident." Similarly, the Chernobyl accident in 1986, the Space Shuttle Columbia disaster in 2003, the 2008 financial crisis and the Fukushima Daiichi nuclear disaster in 2011 are, in fact, perfectly normal. We just don't know when or how a black swan will show up.
Luckily, the Renault-Nissan Alliance has teamed with a company called Transdev to develop a fleet of self-driving vehicles "for future public and on-demand transportation," it said in a press release. The project will kick off with autonomous field testing of Europe's most popular EV, the 250-mile-range Renault Zoe. The vehicles will be tested initially at Paris-Saclay, a public and private research campus and university south of Paris. With the open spaces and access to research facilities, university campuses have been popular spots for autonomous cars -- the University of Michigan even created a fake city to test them.
In the UK, large fossil fuelled power stations are being replaced by increasing levels of widely distributed wind and solar generation. We have spent the last 6 years working with some of the UK's leading companies to manage their flexible demand in real-time and help balance electricity supply and demand UK-wide. Using artificial intelligence and machine learning means we can find creative ways to reschedule the power consumption of many assets in synchrony, helping National Grid to balance the system while minimising the cost of consuming that power for energy users. Artificial Intelligence can help us to unlock this demand-side flexibility and build an electricity system fit for the future; one which cuts consumer bills, integrates renewable energy efficiently, and secures our energy supplies for generations to come.
Germany's RDK8 is the world's most efficient coal-fired power plant. If the new, equipment-agnostic technology, called "Digital Power Plant for Steam," were deployed at every existing coal-fired power plant globally, it could eliminate 500 million metric tons of greenhouse gas emissions, GE says -- the equivalent of removing 120 million cars from the road. Looking at the bigger picture, Bell said that the DDP for Steam system will help utilities optmize power generation with a mix of energy sources, whether that includes coal, nuclear, wind or other sources of power. The DDP for Steam system is built on GE's Predix cloud-based platform, as was GE's other solutions for optimizing power, like its Digital Wind Farm.
Walking on two legs, they have the potential to serve as department store guides, assist the elderly with daily tasks or carry out nuclear power plant rescue operations. "Two weeks ago 19 brave firefighters lost their lives," said Gill Pratt, a program manager at the Defense Advanced Research Projects Agency, part of the Pentagon, which oversaw Atlas's design and financing. Even before the Fukushima disaster, Marvin Minsky, a pioneer in artificial intelligence research, castigated the nuclear power agency for being unprepared for disasters. It is the Defense Advanced Research Projects Agency, not the Defense Advanced Projects Agency.
Ice wall to stem Fukushima leak The Tokyo Electric Power Company (TEPCO) on 31 March began freezing the soil surrounding reactors 1 to 4 of the disaster-stricken Fukushima Daiichi nuclear power plant. China's Go A team of Chinese scientists plans to challenge Google DeepMind's Go-playing artificial-intelligence algorithm with its own program by the end of 2016, Chinese state news has reported. Laser beam added The Linac Coherent Light Source (LCLS), the world's brightest X-ray free-electron laser, began a US$1-billion construction project on 4 April to add a second beam. Gorilla decline Numbers of the largest primate on the planet, Grauer's gorilla (Gorilla beringei graueri), have plummeted since 1995, according to a report from the Wildlife Conservation Society (WCS).
Sebastian Thrun, the former Stanford University professor who helped to develop Google's driverless car, questions whether there will ever be a big market, though he says: "I think it's fascinating to see how people react to it and tease out deeper truths about humanity." The US is "by far the world leader" at the moment in autonomous robots, according to Melonee Wise, chief executive of Fetch Robotics, a Silicon Valley start-up. These include Preferred Networks, a machine learning company which is working to apply AI to robots and autonomous driving systems and has teamed up with powerful manufacturers such as Fanuc and Panasonic. "It takes effort to link hardware, software, and network technologies," said Toru Nishikawa, Preferred Networks' chief executive.
