    摘要: A nuclear plant is provided with a pipe-passivating alkali-injecting device including an alkali-injecting tank, an actuator, a counter-balance valve, a pressure gauge, exhaust valves and switching valves. The actuator is connected to the alkali-injecting tank via a first pipe. The counter-balance valve is connected to the actuator via a second pipe and connected to the alkali-injecting tank via a third pipe. The pressure gauge is provided between the actuator and the counter-balance valve and connected to the second pipe. The exhaust valves are connected to the first and second pipes, and so are the switching valves. The alkali-injecting tank, the actuator and the counter-balance valve are used together to expel gases from the pipes while injecting alkali, thus effectively avoiding feedback of liquid in the nuclear plant, transmitting pure alkali in the pipes, and reducing damage to the pipes.

    摘要: A device for detecting steel is provided. The steel is used in a nuclear plant. The device has a detecting circuit of electrochemical corrosion potential (ECP) and alternative current (AC) impedance. An environment in a boiling water reactor (BWR) is simulated under hydrogen water chemistry (HWC). The environment is used for detecting intergranular stress corrosion cracking (IGSCC) of components coated with different precious metals. Thus, effect of coating different precious metals on steels can be evaluated for HWC.

    摘要: A method is disclosed for making Ru—Se and Ru—Se—W catalyst. In the method, carrier is processed with strong acid and poured into first ethylene glycol solution. Ultra-sonication and high-speed stirring are conducted on the first ethylene glycol solution, thus forming carbon paste. The carbon paste is mixed with second ethylene glycol solution containing at least one nanometer catalyst precursor and an additive. High-speed stirring is conducted to form mixture. The mixture is heated so that Ru—Se catalyst is reduced. The mixture is filtered to separate the carrier. Then, the carrier is washed with de-ionized water. Conducting drying and hydrogen reduction are conducted to make the Ru—Se catalyst on the carrier.
