NuGas: adding a CCGT to a nuclear power plant

摘要

Linking the steam cycles of a nuclear plant and a CCGT promises large efficiency gains. In the course of two years' development, power consultancy PB Power (PB) has created a new thermal cycle, Linking the saturated steam cycle of a nuclear plant to a CCGT (combined cycle gas turbine) steam cycle, this innovative NuGas(tm) cycle achieves an exceptional gas to power efficiency, For example, using prudent design practice, an F Class gas turbine in the NuGas cycle would deliver an efficiency of around 62%, compared with a CCGT plant at around 57%. The business implications of achieving such an efficiency gain at capital costs comparable with a conventional CCGT are substantial.
