Bulletin of the Atomic Scientists: “From 2005 to 2011, China rapidly developed its nuclear power capacity. In 2010 alone, it began operations at two new reactors and broke ground on 10 more, accounting for more than 60 percent of new reactor construction worldwide and making the Chinese nuclear industry by far the fastest-growing in the world. By the end of 2010, China had 14 nuclear reactors in operation with a total capacity of about 11 gigawatts electric, or GWe. That was still a relatively small amount — in contrast, the United States had 104 commercial reactors with a total capacity of about 100 GWe in 2010 — but China was pursuing ambitious plans to rapidly expand.
Then came the tsunami and earthquake that led to Japan’s Fukushima Daiichi meltdown in March 2011, the world’s worst nuclear accident since the Chernobyl disaster in 1986. After Fukushima, China changed course dramatically, slowing the pace of nuclear development to focus on safety. The slower pace is reassuring, but to really be a leader on nuclear safety, China should speed up the adoption of new laws on nuclear energy and enhance the independence and authority of nuclear safety regulators.
Putting the Brakes On. According to a government plan issued in 2007, China planned to install a total nuclear capacity of 40 GWe by 2020, which would account for about 3 percent of electricity generation nationwide. Many officials and experts expected that the number would actually increase further, to more than 80 GWe.
In its initial, March 2011 reaction to Fukushima, though, China’s State Council, the nation’s governing body, decided to suspend approval of new nuclear power stations, conduct comprehensive safety inspections of existing plants, and review all nuclear projects including those under construction. In October 2012, after concluding the inspections and reviews, the State Council issued a new plan that represents a serious and cautious reevaluation of safety issues and the pace of development. Called the Medium- and Long-term Nuclear Power Development Plan (2011-2020), its proposals include:
A return to normal construction at a controlled and orderly pace.
Permission for a limited number of new nuclear power reactors to be built in coastal sites that have been comprehensively evaluated.
A ban on new inland nuclear power projects, because the government fears a shortage of cooling water should accidents occur at such plants.
A requirement that all new projects meet the safety standards of the world’s most advanced nuclear reactors, known as third generation or Gen III reactors. Compared to earlier technology, these new designs incorporate improved fuel technology, superior thermal efficiency, passive rather than active safety systems, and standardized designs aimed at reducing maintenance and capital costs.
Based on the new plan, China will only approve a few new reactor construction projects before 2016. China now expects to grow its total nuclear capacity to 58 GWe by 2020, rather than the more than 80 GWe previously expected.
The government resumed approval of new nuclear power projects in December 2012, just as the new plan was issued. Several inland nuclear power projects where significant preparation work had already begun will be suspended, with some of their equipment likely transferred to coastal sites. While the pace of Chinese nuclear development will slow in the near term, the country’s long-term goals haven’t changed significantly. China continues to emphasize nuclear power as a crucial part of its energy mix. A government white paper issued in October 2012 observed that “as nuclear power is a high-quality, clean, and efficient modern energy resource, its development is of great importance for optimizing the nation’s energy structure and ensuring national energy security.” The white paper put China’s nuclear energy target at 40 GWe by 2015.”
