Abstract: A combined-cycle power plant, a steam thermal power plant, and a method for operating the power plant, which are capable of effectively utilizing raw fuel produced from medium- or small-scaled gas fields and oil fields. Raw fuel produced from a gas field is separated into a gas component and a liquid component by a separator. The gas component is burnt in a combustor of a gas turbine, and resulting motive power is converted to electricity by a power generator. The liquid component separated by the separator is burnt in a steam generator to generate steam that is supplied to a steam turbine. Resulting motive power of the steam turbine is converted to electricity by a power generator. Since the electricity generated by the power generators is AC power, the AC power is converted by a converter to DC power that is transferred from the vicinity of the gas field to a consuming area via a cable.

Abstract: A reactor core of a fast breeder reactor is supported by a core support within a reactor vessel. The reactor vessel is provided with a first or lower sodium chamber for accommodating low temperature sodium, a second or intermediate sodium chamber for accommodating low temperature sodium and a third or upper sodium chamber for accommodating high temperature sodium heated by passage of the low temperature sodium through the reactor core into the third sodium chamber. Low temperature sodium is introduced into the second sodium chamber arranged between the first and third sodium chamber for cooling the core support.
