Um the Chinese government is involved in the building of those reactors in China, and they are flush with cash. In the US, we have public utilities or mechant power producers who have to go to the capital markets. The reason for the government loan guarantees is that the utilities could not get financing from the financial markets.
It could very well be that the government is over-estimating the risk of default on the $7.5 billion loan.
The Chinese government can also accept less stingent safety standards since they are will to accept the loss of life that would be unacceptable in the US (unless one lives in New Orleans
). And the Chinese people cannot sue the government or companies they way its done in the US.
Large forgings have so far been ordered from Japan until shops can be established in the US.
Which two nuclear reactors? Usually the government has a very good reason not to issue a license. There are two sites under construction - South Texas and Vogtle. The rest are either slowly moving along or have been suspended or deferred for various reasons.
