I actually do know a little bit about this from what I can gather the EMALS on the Chinese carriers are all on independent power tracks. The Ford class has them in sequence a much less reliable system as if the first one goes there all gone untill it's fixed. Also more complex so even if there designed better there is still more moving parts. Tho iirc the Ford class can deliver more launches before power is a issue as it's more efficient.
Also I know chinas also have battery backup storage for power it is possible the launches we seen were that and not pulling power from the reactor
dont know if that's the right call or not. I get how the sequence issue can basically incap your carrier, my question is if your going to redesign it back to steam, why not just remove the sequence issue? Tho I admit that could be a large enough issue that cost and time mean it's steam or risk having a aircraft carrier that doesn't work in case of a break down or damage.
