Abstract: | The effect is analyzed of the increase of the effective pressure ratio, the regeneration factors, the initial gas pressure, temperature of the fuel element cladding, hydraulic resistance of the gas circuit on the internal efficiency of a nuclear gas turbine unit, taking into account the characteristics of the active zone of the reactor. The results are given of the effect on the efficiency of a nuclear gas turbine unit (NGTU) of the intermediate heating and cooling of the gas. A possible circuit for a NTGU is discussed, with one intermediate heating and three-stage cooling of the gas;Translated from Atomnaya Énergiya, Vol. 20, No. 5, pp. 412–415, May, 1966. |
