Estimating the efficiency from using hydrogen toppings at nuclear power stations

A low-cost version of modernizing a nuclear power station is considered in which the main profile (standard size) of the power unit is retained and insignificant changes are made in the turbine unit’s operational parameters. These changes consist in that steam supplied to the high-pressure cylinder is subjected to slight initial superheating, and that that the design superheating of steam upstream of the low-pressure cylinder is increased to some extent. In addition, different versions that can be used for heating the working steam to the required temperatures in the H 2 /O 2 steam generator’s mixing chamber are analyzed.
