| Abstract: With the change of Marine ecological environment, the invasion of Marine organisms has become the biggest challenge to the safety of nuclear power cold source. Due to the invasion of Marine organisms, the power of nuclear power units is reduced, and even the jump of the reactor happens from time to time. To reduce the occurrence of such events, the researchers tried to develop new chemical methods to control and inhibit the growth of benthic organisms. Through chemical prevention and control experiments, the effectiveness and effective concentration of chemical methods for controlling benthic organisms were verified. Through comparative analysis, chlorine ingot was finally selected as a chemical control agent for controlling benthic sea organisms. In the process of chemical prevention and control of benthic sea organisms by chlorine ingot, residual chlorine monitoring results met the requirement of 0.2 mg/L for allowable discharge concentration of residual chlorine in cooling water of nuclear power plant, and no significant impact of chlorine ingot release process on the surrounding sea water environment was found. The Marine biochemical prevention and control method established by using chlorine ingot is relatively new and challenging. The application results show that this method has a good effect on the prevention and control of the cold source of Acaudina molpadioides (Acaudina molpadioides) in the coastal power station, and is suitable for the safety guarantee of the cold source of the coastal power plant. |
