摘要:
Method and system for supplying emergency power to nuclear power plant, wherein the method includes, providing accumulator battery system, connected to emergency bus, the accumulator battery system is monitored by online monitoring system; in case of power loss of electrical devices of the nuclear power plant, the online monitoring system starts the accumulator battery system to provide power supply to the electrical devices of the nuclear power plant via the emergency bus. The present application is adapt to the key technologies and battery management technologies of million kilowatt-class advanced pressurized water reactor nuclear power plant, facilitating to improve the safety of the nuclear power plant in case of serious natural disasters beyond design working conditions.
摘要:
Disclosed are a reagent for testing the purification capacity of a radioactive gas in a nuclear power plant, preparation method thereof and an iodide filter testing equipment using this reagent. The reagent is prepared by mixing methyl phosphate compound or dimethyl acetal compound, acetonitrile, trimethyl chlorosilane and radioactive iodine sources and carrying out a reaction at a temperature of 20°C-50 °C under an inert gas for 10-40 min. The prepared products except methyl iodide are non-toxic or little toxic to the nuclear grade impregnated activated carbon in the iodide filter.
