Each second, a nuclear power plant generates $3200$ MJ of heat energy from nuclear reactions in the reactor's core. This energy is used to boil water and produce high$-$pressure steam at $290C.$ The steam spins a turbine, which produces $700$ MW of electric power, then the steam is condensed and the water is cooled to $35C$ before starting the cycle again.

What is the maximum possible thermal efficiency of the power plant?
