This cut-away rendering of the MIT nuclear battery concept shows important components such as the instrumentation and control module, the reactor, and the power module. Credit: Massachusetts Institute of Technology ===================================================================================== We may be on the brink of a new paradigm for nuclear power, a group of nuclear specialists suggested recently in The Bridge, the journal of the National Academy of Engineering. Much as large, expensive, and centralized computers gave way to the widely distributed PCs of today, a new generation of relatively tiny and inexpensive factory-built reactors, designed for autonomous plug-and-play operation similar to plugging in an oversized battery,...

Mini nuclear stations can be mass manufactured and delivered in chunks on the back of a lorry, which makes costs more predictable. Rolls-Royce is leading a consortium to build small modular reactors (SMRs) and install them in former nuclear sites in Cumbria or in Wales. Ultimately, the company thinks it will build between 10 and 15 of the stations in the UK. They are about 1.5 acres in size - sitting in a 10-acre space. That is a 16th of the size of a major power station such as Hinkley Point. SMRs are so small that theoretically every town could...

In what would be a milestone for advanced nuclear power, China's Nuclear Engineering Construction Corporation plans to start up a high-temperature, gas-cooled pebble-bed nuclear plant next year in Shandong province, south of Beijing. The twin 105-megawatt reactors--so-called Generation IV reactors that would be immune to meltdown--would be the first of their type built at commercial scale in the world. Construction of the plant is nearly complete, and the next 18 months will be spent installing the reactor components, running tests, and loading the fuel before the reactors go critical in November 2017, said Zhang Zuoyi, director of the Institute of...

For years nuclear scientists have talked about a revival of molten salt reactors, which are powered by a liquid fuel rather than solid fuel rods, that will help spark the long-awaited “nuclear renaissance.” Recent developments indicate that this alternative nuclear power technology is finally making progress toward commercialization. A consortium of research institutes and universities working under the aegis of the European Commission, including the Technology University of Delft (TU Delft), in the Netherlands, France’s National Center for Scientific Research, and the Commission’s Joint Research Center, in Brussels, in August embarked on a four-year research program designed to demonstrate the...
