Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a supercritical steam combined cycle and its method. SOLUTION: The supercritical steam combined cycle system includes a gas turbine 16, a supercritical steam turbine system 18 and a supercritical steam heat recovery steam generator (HRSG) 30. The HRSG includes a supercritical evaporator 44 arranged to supply steam to a superheater at an inlet and a reheater 50, 52 receiving cold reheat steam from and returning reheated steam to the steam turbine system 18. The reheater includes a first section 50 disposed downstream of and a second section 52 disposed upstream of an exhaust gas flow path of the supercritical evaporator 44. Low temperature reheat steam from the steam turbine system 18 is received by the first reheater section 50 and steam leaving the first reheater section is supplied to the second reheater section 52 upstream of the supercritical evaporator 44.
