Question:

Electrical power is to be produced from a steam turbine connected to a nuclear reactor. Steam is obtained from the reactor at 540 K and 36 bar, the turbine exit pressure is 1.0 bar, and the turbine is adiabatic. 

a. Compute the maximum work per kilogram of steam that can be obtained from the turbine. 

A clever chemical engineer has suggested that the single-stage turbine considered here be replaced by a two-stage adiabatic turbine, and that the steam exiting from the first stage be returned to the reactor

Nuclear reactor leee Steam 540 K 36 bar 540 K 36 bar 540 K P* Turbine W, Turbine W, Turbine W, 1 bar P* Part

and reheated, at constant pressure, to 540 K, and then fed to the second stage of the turbine. (See the figure.)


b. Compute the maximum work obtained per kilogram of steam if the two-stage turbine is used and the ex- haust

d. Compute the heat absorbed per kilogram of steam in the reheating steps in parts (b) and (c).
