Bottleneck in nuclear plants

As I've outlined in my nuclear series, the rationale approach would be to go with 4 AP1000 reactors, like in China. The problem is that there is only one place in the world that can forge the main reactor vessel.

This forge is in Japan, and they make the vessel like a Samurai sword. They are booked up until the next century (or at least my lifetime). Ontario's diddling doesn't help us here.

This most likely forces us to use the AECL reactor, since nobody else is making them, and the calandria is multi-part forge. Nevertheless, we shall keep on partying with all the vendors until December!
