A gas-reforming catalyst is modified to obtain stability in high temperature. The catalyst uses &#x3b1;-AlOas a carrier and is nano-porous. Hence, reaction surface is greatly broadened; and platinum contained inside does not become bigger after times of use. The catalyst does not deposit carbon and has long life. The stability of the catalyst can be still remained even at a temperature higher than 800&#xb0; C.

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.
