Taking into account the background regarding the selection and specification parameters of sacrificial anodes for different parts of water-cooled reactors in the past, the generally available industrial-grade data can serve as a reference; relevant information will be released in 2026. It is recommended to rely on the officially measured nuclear-grade data: Zinc alloy block anodes (used in spent fuel pools) have a design life of 15–20 years in a water environment with boron and low resistivity. Based on a specification of 38 kg, they need to be replaced when only 20% of their original mass remains due to variations in water quality during operation. Brace-type zinc anodes (for circulating water pipelines) have a design life of 10 to 15 years under fresh water cooling conditions; anode units of 12 kg can provide protection for approximately 8 to 10 meters of DN1000 pipelines. Zinc strip anodes (for heat exchangers) have a design life of 8 to 12 years under conditions of low current density in the tube sheet; they consume approximately 0.2 kg per unit length per year, which is suitable for the regular maintenance cycles of heat exchangers. Aluminum alloy block anodes (for seawater systems) are designed to have a service life of 20–30 years in coastal high-chloride cooling water environments; the 22kg version of these anodes can deliver a protective current stably over a long period of time. Small magnesium alloy anodes (for drain pipelines) have a design life of 3 to 5 years under conditions of high resistivity; they need to be replaced simultaneously with the annual maintenance of the pipelines. The specific experimental data for such nuclear-grade scenarios have not yet been fully made public; by using industry-standard formulas along with the actual current values measured on-site, it is possible to more accurately determine the remaining service life of each anode.
