DOE has committed up to $17.5 billion in loans to accelerate the deployment of ten AP1000 nuclear reactors in the U.S. by 2030, but a critical bottleneck remains in the limited heavy-forging capacity needed for reactor pressure vessels, which depends on a small, internationally concentrated supplier base primarily in Japan, South Korea, China, and Russia.
This Wire brief sits within Fusion42's coverage of Energy Storage.
◆ ◆ The Wire takeaway
You face an opportunity as DOE loans speed reactor projects but do not expand forging supply. Securing supply or alternatives from the small pool of heavy forging vendors will make or break your project timelines.
