It’s an inefficient way of producing energy. Only 30-35% results in electricity

If you believe that figure, that's still comparable to solar's best ( https://en.wikipedia.org/wiki/Solar-cell_efficiency ).

Optimal steam plants can get do better, exceeding 50% in some configurations ( https://en.wikipedia.org/wiki/Combined-cycle_power_plant#Eff... ). Steam is awesome.

The difference that makes your statement misleading is that solar doesn’t pay for its fuel, the sun shines for free.

What alternative do you propose that's more efficient?

Could you please provide comparable figured of EROI for solar vs Nuclear?

For a useful comparison you have to compare both sides, not give a stat in isolation and assert it is worse without comparing.

30-35% of what? What are the inputs here? What is driving the cost? What are the externalities? And what is the end result in price per kWh?
