...I have no objection. However the environmental problems with extreme global heating we face go beyond machines that merely produce electricity.

To whatever extent the analogy with the IBM computer holds, I'm OK with it. We need to build reactors fast.

However, the BWRX-300 will require enriched U-235 fuel. This is a problem. We can and must do better than that, in particular because we need to put depleted uranium to use.

For the more broader requirements, my boy is working on printable cores for very high temperature reactors that do more than produce steam for electricity. I'm encouraging him to think about reactors that will run for a decade or more without refueling, and will produce high temperatures for flexible use.
