Abstract
The analysis method for the PSA of the serious accident consequences of nuclear power plant was introduced and the operation rules, i. e. U5 rules on avoiding the containment failure of the nuclear power plant was put forward by the France. When the nuclear power plant happened core meltdown accident, and caused the raising of internal pressure, due to the spray failure of the containment, the U5 rules will make the gas inside the containment releasing to the environment through sand-bed filter, then the pressure in the containment will be relieved. The practical claculation was based on the being built nuclear power plant as the chief source and analysed the effect of U5 rules on the serious accident consequences of the nuclear power plant. In conclusion, some valuable results were given.
