Comparative analysis of coolant average temperature control schemes for PWR nuclear power plant

The coolant average temperature control system is the core control system of PWR nuclear power plant. The paper gives a comparative analysis among different coolant average temperature control schemes, through which it makes clear that the coolant average temperature control scheme based on practical engineering is mature, and override the other three schemes. The reason is that the simulation results of the other three are insufficient or only approaching to the first scheme. It is greatly encouraged to discuss the coolant average temperature control scheme from different angles. Although such discussion cannot obtain the immediate results overriding the current scheme, it will bring aspirations even breakthroughs in this field. (author)
