Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Fission product release tests and control tests recently conducted at Oak Ridge National Laboratory have provided new experimental data that help characterize the mechanism of fission product tellurium release behavior under severe light water reactor accident conditions. Release of tellurium from the fuel rod segments has been found to be dependent on the rate and extent of cladding oxidation. Tellurium was observed to be significantly retained by metallic Zircaloy cladding at test temperatures up to 2000°C. The results indicate that the tellurium was bound by the Zircaloy cladding as zirconium telluride, but once the available metallic zirconium was oxidized by the steam, tellurium was released in favor of continued zirconium oxide formation. The collection behavior of the released tellurium indicated that it was probably released from the fuel rods as tellurides of tin, cesium, and rubidium rather than as elemental tellurium.
