They're nuclear submarines that use very small nuclear reactors to charge the batteries instead of driving turbines, as little as a few tens of kilowatts.
They're cheaper, safer and quieter than standard nuclear subs while being air-independent, but they are not as fast as nuclear subs and not as silent as diesel subs.
My Navy uses a similar concept. You can actually keep the reactor the same size and play it out far better than just batteries. Either way, you'll still need a steam system to produce the electricity in the first place; it's far more effective if you make your electrical turbines large enough to provided the electricity that also drives your shaft. Keep batteries as a backup.
Still quieter than nuclear subs, but just as much power and more space (or smaller submarine overall).
Do you really need a steam system? Why not just do it Swedish style and use a Stirling engine?
