Couple of problems here . . .
1). The relative humidity of air depends in a really big way on the temperature of the air.
2). There's no such thing as a "cubic sq ft".
The nuclear reactor produces heat which is used to raise steam to feed a steam turbine/generator set
The steam turbine will produce 400 J of output, and the steam engine 250 J. That's what the efficiency figure means.

The total heat of steam, also known as enthalpy of steam, is the amount of heat required to raise the temperature of water to its boiling point and then convert it into steam without changing its temperature. It is the sum of sensible heat and latent heat of vaporization.

As you probably already know, water boils at 212F (100C). This only applies when at sea level with an atmospheric pressure of 14.7psia. To raise the boiling point all you need to do is raise the pressure. In a steam plant where steam is used to drive turbines, the water is pressurized by heating it in an enclosed system. As the water turns to steam, the steam has no where to escape and the pressure in the enclosed system begins to rise. As the pressure rises so does the boinling point. Some plants will raise the temperature to 500F which corresponds to a pressure of about 620psi.
Yes, if methane gas is added to steam at 600 degrees Celsius in a combustion chamber, the methane can combust to further raise the temperature of the steam. This process can yield more heat energy and increase the overall temperature of the system.
Yes. The specific heat capacity of liquid water is 4.184 J/g•oC, and the specific heat capacity of steam is 2.010 J/g•oC.

Yes. This happens, for example, when steam is used to raise something like a balloon.
You put coal to boil the water in the boiler to raise steam to drive the pistons which turns the wheels.
It equals one kilpod.
