| Abstract: | The P-1 radiation model was applied to solve the temperature profiles inside the dome. The 3D numerical simulation was done based on the CFD technique for the dome in R55-region of CPR1000 nuclear power station, and the measurement was conducted to validate the CFD model. The results showed that the simulation values agreed well with test value about the temperature in the empty dome where Z was 11m in 6 different ages, the max relative error and the average error was 3.23% and 1.05%, respectively. The temperature grades were obvious in vertical direction and the maximum temperature different was 6℃ at 9 o’clock 26th, June. The P-1 radiation model was proved in modeling the effect of solar radiation on the thermal environment inside the dome of the nuclear power station. |
