EEDM Equation Of The Thermal-economic Analysis For Nuclear Power Units

This text is on the basic analysis of nuclear power units thermal system, comparing the differences between normal generation thermal system, and follows the analysis of the energy-efficiency diatribution matrix equation which is generation thermal system oriented, combines characteristics of the two-phase flow system of Press Water Reactor nuclear power units, thus sets up virtual thermal system of nuclear power units thermal system, therefore builds up the EEDM equation which suits the economic analysis of nuclear power unit thermal system, and provides an detail explanations to the structure and rule of uses. According to the test result of 900 MW Press Water Reactor nuclear power units, the equation is appropriate and useful. In addition, it concludes several factors that influence the economic efficiency of nuclear power units thermal system based on the characteristics of them and provides reference.
