That could have a significant impact on the international nuclear power industry. The PRC has rapidly growing electricity requirements and currently has the largest number of proposed and building nuclear reactors in the world. They are a mixture of domestic and foreign designs from Canada, Europe, Russia, and the United States, so it could have trickle down effects for suppliers.
In terms of the future of the PRC nuclear power program, it could depend on what type of plant the incident occurs in, and what the cause is traced to.
