UCB’s Per Peterson on China’s advanced nuclear program

In this essential Breakthrough interview Per Peterson summarizes China’s advanced nuclear development – including the US – China collaboration. I think this collaboration is the one global effort that could have a material impact on climate change. US support for the cooperation seems to be hidden from the usual political shout-fest — at least if there is anyone in the executive who is taking credit for even allowing the cooperation I’ve not heard of it. Imagine what could be accomplished if there was enthusiastic, high-level backing and 10x as much funding? This is just a fragment of the interview focused on China:

What are China’s plans for advanced molten salt nuclear reactors?

China has a huge nuclear program and is building almost every kind of reactor possible, including a number of experimental advanced reactors. Two years ago the Chinese Academy of Sciences decided to pursue a thorium liquid-fueled molten salt reactor, but first decided to build an intermediate reactor that uses a solid fuel with salt as coolant. (The choice to build a solid fuel reactor reduces the licensing risk without heavily compromising performance.) In 2015, China will be starting the construction of the 10 MW solid-fueled thorium molten salt test reactor. By 2017 they hope to have this reactor operating. And by 2022, they hope to have commissioned a 100 MW thorium molten salt commercial prototype reactor. Alongside this effort, the Chinese will be developing a 2 MW liquid-fueled reactor that will enter the final stages of testing in 2017.

Are you collaborating with the Chinese on this effort?

There is an ongoing formal collaboration between the Chinese Academy of Sciences (CAS) and the US Department of Energy (DOE). The DOE has a memorandum of understanding with the CAS. Under this formal umbrella, our research group has an informal relationship with the Shanghai Institute of Physics. There is also a cooperative research agreement being developed between China and Oak Ridge National Laboratory in Tennessee, which would provide funding for China’s thorium molten salt research effort.

Tell us more about US involvement in the Chinese effort to commercialize advanced nuclear technologies.

The US DOE has been reviewing the Chinese effort to build a molten salt reactor. The Chinese program has been using US expertise in reactor safety, and US experts have reviewed the early test reactor design and remain engaged. So far, China’s nuclear regulatory policy has been to adopt and follow the safety and licensing regulation of the exporting country. Russian-built reactors in China are have adopted a regulatory approach similar to that of Russia. Likewise, licensing for the Westinghouse AP1000s that are being built in China is following a US approach. There appears to be an emerging, consensus approach in the US and in China for safety for molten salt reactors as well.

How should the US participate in the commercialization of these reactors?

My view is that the United States needs to maintain the capability to independently develop advanced nuclear designs that are being studied and will be commercialized in China. Maintaining such capability could encourage US-China joint ventures, which could accelerate development and thus ensure that commercial designs are deployed at large scale as soon as possible. The United States has a lot of expertise in the areas of nuclear safety and licensing, and could bring such expertise to US-China partnerships. If new advanced nuclear designs are simultaneously licensed in both the US and China, the possibility for large-scale deployment increases.

Do you think such reverse engineering is possible? Isn’t China keeping their plans secret?

The Chinese Academy of Sciences has been remarkably open and transparent in their effort to build their thorium molten salt reactor. They’ve been doing a lot of international collaboration. All of the reports are published in an extraordinary level of detail. This collaboration is really important if we want to see this technology developed and deployed soon enough to make a real difference in helping reduce climate change. If China can stay on track to commission a 100 MW commercial scale reactor by 2022, it would be fantastic if this reactor could include substantial contribution by US industry as well. This kind of collaboration could lead to a joint venture effort that could result in more rapid and larger near-term deployment.
