Depleted zinc oxide

Depleted Zinc Oxide (English Depleted Zinc Oxide ), DZO short, is a term used in nuclear technology.

Zinc oxide is the cooling water from boiling water added to improve the corrosion behavior of coming into contact with the cooling water components. The amount of corrosion products, and radioactive corrosion products entering inevitable in the cooling water is thereby reduced, accordingly the radiation of the cooling circuit components after extended reactor operation, resulting from the deposited corrosion products. This results in maintenance, etc. to a lower dose exposure of personnel.

Unfortunately, however, the in the natural isotope mixture of zinc ( 48.6 % 64Zn, 66Zn 27.9%, 4.1% 67Zn, 68Zn 18.8%, 0.6 % 70Zn ) isotope 64Zn contained in the reactor by neutron capture in the radioactive isotope 65Zn converted. This (actually: his daughter nuclide 65Cu ) is a relatively hard gamma radiation ( about 1.1 MeV ) from.

DZO into the portion of the main isotope 64Zn is drastically reduced ( <1 %). Characterized 65Zn less is formed, and thus further reducing the radiation of the components of the cooling circuit accordingly.
