Considering the application context of reactor neutronic media mentioned earlier, there are no clear and uniform service life standards for corrosion inhibitors specifically designed for reactors in the available public information; their actual effective duration is influenced by a variety of factors. The key influencing factors are the composition, structure, and initial dosage concentration of the corrosion inhibitor itself; these constitute the fundamental conditions that determine its duration of effectiveness. Only when the concentration remains above the effective threshold can it continue to provide protective effects. The intense radiation field inside the reactor accelerates the decomposition and consumption of the corrosion inhibitor, and high-temperature conditions can also destroy its film-forming structure, significantly shortening its effective lifespan. Too fast flow velocity of the medium can disperse the corrosion inhibitor film, continuously depleting its active ingredients and further reducing its service life. Industry-standard approach: In actual nuclear power operation and maintenance, the remaining concentration of corrosion inhibitors in the medium is monitored regularly via online testing, and the agents are replenished as needed to keep their concentration within an effective range, thereby ensuring long-term corrosion protection.
