Natural abundant Zinc is available in the following stable isotope: 64Zn 48.06%
These zinc isotopes can be engineered, both in distribution and in chemical form, to meet the specific needs of customers. Using the most advanced centrifuge technology in the world; concentrations can be enriched to exceed 99% or depleted below 1%.
Depleted Zinc Isotopes Usage
Zinc, depleted in the isotope 64Zn, is presently used as an additive in the cooling water systems of BWR nuclear reactors worldwide. The majority of U.S. reactors now utilize depleted zinc oxide (DZO) injections while PWR operators have started to evaluate the technology. Preliminary results indicate that depleted zinc acetate may be more advantageous for use in PWRs.
The addition of 64Zn greatly reduces corrosion processes, including stress corrosion cracking. Furthermore, the added zinc reduces the amount of radioactive 60Cobalt formed because of the irradiation of natural cobalt in the construction materials of the reactor. 60Co is a major contributor to radiation build-up in the cooling systems and therefore causes elevated dose rates of maintenance personnel.
