Reactors being built by China could yield weapons-grade plutonium: US admiral

WASHINGTON • A new generation of nuclear power facilities that China is developing could produce large amounts of plutonium that could be used to make nuclear weapons, the head of the US Strategic Command (StratCom) warned lawmakers this week.

China is developing fast breeder reactors and reprocessing facilities as it seeks to reduce dependence on coal, a top source of carbon emissions. But the plants also produce plutonium that could be used to make nuclear weapons. The first fast breeder reactor is projected to come on line in 2023.

"With a fast breeder reactor, you now have a very large source of weapons grade plutonium available to you, that will change the upper bounds of what China could choose to do if they wanted to, in terms of further expansion of their nuclear capabilities," Navy Admiral Charles Richard, commander of StratCom, told the Senate Armed Services Committee on Tuesday.

StratCom oversees the US nuclear weapons arsenal.

There is no evidence that China intends to divert its potential plutonium stockpile to weapons use, but concern has grown as Beijing is expected to at least double its number of nuclear warheads over the next decade from the low 200s.

China says its nuclear programme is for peaceful purposes.

The Chinese embassy in Washington did not immediately respond to a request for comment.

Last month, a report called China's Civil Nuclear Sector: Ploughshares to Swords, said the country has started building a second plant to reprocess spent nuclear fuel that could be commissioned before 2030.

Adm Richard said US officials learnt recently about how quickly China is moving to build its civilian nuclear programme. About a week ago "we became aware of that and started the process to understand the implications", he said.

Mr Christopher Ford, a former nonproliferation official at the State Department under president Donald Trump, said US officials may not be able to do much on the issue besides denounce it and "point out how destabilising it is in the region... and put pressure on China not to do this economically needless and strategically dangerous thing".

Nuclear waste reprocessing has not been practised for decades in the United States after president Jimmy Carter halted it on proliferation concerns.
