Abstract: An economic study is made for the characteristics of the secondary-circuit of PWR nuclear power plant. A short-cutconcept of the heat to power conversion coefficient of extracted steam is adopted for system design and operation diagnosis, and a quantitative analysis method  for thermal system of the secondary-circuit of PWR nuclear power plant is proposed.
