Recently, is applied to the AP1000 project relies on the 8 inch low blasting valve third immersion test completed successfully in America Alabama NTS laboratory. The day after dismantling the results show that, without anytrace of water body, meet the specification requirement of zero leakage, the country's nuclear engineering company limited supervision personnel involved in the whole process of dismantling process valve. The test is successful, will have a very positive impact on the future of 8 inch smooth blasting valve shipped, constructionso as to effectively support AP1000 based on project. Blasting valve immersion test is an important link of valveequipment identification test of blasting, which is aimed at the simulation under severe accident conditions, the blasting valve body can meet the zero leakage, the cartridge can be barrier free detonated, ensure the valve opening, the realization of the reactor coolant system of automatic pressure relief, low pressure safety injectionand containment recirculation function.
