China’s waning nuclear interest
Nuclear power continues its decline as renewable alternatives steam ahead, World Finance, Author: Courtney Goldsmith, October 15, 2018“…………China’s waning nuclear interest Of the 10 reactors that started up globally in 2016, half were located in China. Meanwhile, nearly 40 percent of the total reactors currently in construction are Chinese. However, China has not launched a new construction of a commercial reactor since December 2016. The country had planned for 58GW of total nuclear capacity to be in place by 2020, but having failed to get 30GW of new plants under construction by 2018, China’s lead in the field of nuclear power may be slipping. What’s more, even in this hub of nuclear activity, renewable generation is moving even faster. As of July 2017, China had 37 operating nuclear reactors with a total net capacity of around 32GW. In 2017, however, the country added a whopping 53GW of solar power. “To illustrate the speed with which things change, and [which] the invading species is taking over, if you only go back five years in 2012, Germany was the world record holder in the addition of [solar PV] with 7.5GW,” Schneider said. “Now it’s China with [53GW] five years later. The speed is just unbelievable.” The return of small reactors Proponents say SMRs will be cheaper and safer than conventional nuclear plants, and will be capable of competing with solar and wind power. Desbazeille said SMRs were a “game changer” that could put Europe back at the forefront of nuclear technology……. But while SMRs are purported to be the key to transforming the nuclear sector, history has painted a troubling picture: SMR designs have been in the works for decades, but none have reached commercial success. In fact, Westinghouse worked on an SMR design for about a decade, but the project was abandoned in 2014. At the time, then-CEO Danny Roderick said: “The problem I have with SMRs is not the technology, it’s not the deployment – it’s that there’s no customers.” A number of companies continue to work on new designs, however. US firm NuScale Power plans to develop an SMR to re-establish the country’s leadership in nuclear technology. The design is currently under review for approval by US regulators. While NuScale is seen as one of the firms closest to commercialisation, it may be too late by the time the arduous process of securing approvals is completed. Therefore, by the time SMRs are ready for mass deployment, the energy debate may already be over. “Look at what happened over the past five years,” Schneider said. “But can you imagine what will happen in the next 10 years? This is going to be a completely different world.”… Although SMRs have been talked about for decades, the progress made so far has been tiny. New technologies in the nuclear sector take a huge amount of time to develop – just look at the struggle to build EPRs in Europe. Plus, opting for a small design cuts out the economies of scale, or the cost advantages that come about due to increasing the size of a project. This is something nuclear projects often rely on. A report by researchers at Harvard University, Carnegie Mellon University and the University of California, San Diego concluded that in the absence of a “dramatic change in the [US] policy environment”, a convincing case for a domestic market for SMRs is difficult to make. Much of the nuclear debate is powered by opinions and estimates, but looking at the hard data, it’s strikingly clear that the industry is in a slow and inevitable decline. China’s plans to become a nuclear powerhouse have been overshadowed by its huge investments in renewable energy – in fact, the number of new construction starts (see Fig 2) has fallen around the world as stubbornly high costs and complex designs make new nuclear a hard sell. Even in spite of nuclear power’s role in reducing carbon emissions, the potential safety issues and environmental impact of a meltdown are too big to ignore. With the cost of renewable and battery technologies expected to continue falling, wind and solar power appear to be the next golden opportunity. https://www.worldfinance.com/markets/nuclear-power-continues-its-decline-as-renewable-alternatives-steam-ahead
