FNR POWER

The FNR design must also prevent unplanned drops in the liquid sodium coolant inlet temperature to the fuel assembly, which could potentially cause fuel melting... in order to maximize the steam thermal power output suitable for electricity generation while preventing deposition of NaOH on cool heat exchange surfaces which might become be a problem when Tsr falls below 318 C. At the FNR's maximum rated thermal load the NaK return temperature Tsr is about 20 degrees C above the steam generator water temperature corresponding to the satuation steam pressure in the steam generator. The saturation steam pressure is controlled at a fixed setpoint of about 10.0 MPa by a pressure regulating valve which regulates the flow of discharge steam from the steam generator. The discharge steam is fed to a steam turbine where it expands to generate electricity.
