How nuclear capital ships in 1938 would alter Japanese strategy

What changes if Japan has nuclear-powered capital ships in 1938?

The answer imagines capital ships accompanying the Pearl Harbor force and more attack waves, while the participants disagree about the reactor assumptions.

The premise supplies reliable nuclear plants and trained crews to Japanese capital ships in 1938. The first answer imagines those ships accompanying the Pearl Harbor force, giving it the confidence to launch additional waves. A participant then predicts early refueling and parts problems. Alex rejects the short refueling interval for this scenario, interpreting the magical gift as long-life plants with about twenty years between refuelings. The disagreement matters because the military answer changes with the equipment assumed. A follow-up distinguishes commercial and naval reactor fuel choices and notes the lengthy work involved in refueling and returning a carrier to service.
