The supercritical carbon dioxide (S-CO<sub>2</sub>) is a possible cooling system for the new generations of nuclear reactors and fusion reactors. The S-CO<sub>2</sub> power cycles have several advantages over other possible coolants such as water and helium. The advantages are the compression work, which is lower than in the case of helium, near the critical point and the S-CO<sub>2</sub> is more compact than water and helium. The disadvantage is so called Pinch point which occurs in the
