Abstract EN
Chinese large-capacity advanced PWR under construction in China is a new and indispensable reactor type in the developing process of NPP fields.
At the same time of NPP construction, accident sequences prediction and operators training are in progress.
Since there are some possible events such as feedwater pumps trip in secondary circuit may lead to severe accident in NPP, training simulators and engineering simulators of CI are necessary.
And, with an increasing proportion of nuclear power in China, NPP will participate in regulating peak load in power network, which requires accuracy calculation and control of secondary circuit.
In order to achieve real-time and full scope simulation in the power change transient and accident scenarios, RELAP5/MOD 3.4 code has been adopted to model the secondary circuit for its advantage of high calculation accuracy.
This paper describes the model of steady state and turbine load transient from 100% to 40% of secondary circuit using RELAP5 and provides a reasonable equivalent method to solve the calculation divergence problem caused by dramatic two-phase condition change while guaranteeing the heat transfer efficiency.
The validation of the parameters shows that all the errors between the calculation values and design values are reasonable and acceptable.
