SIGNIFICANT PROJECTS

Rizzo Associates Czech (formerly Stevenson and Associates, Office in Czech Republic) has participated in a number of projects, primarily in the field of peaceful use of nuclear energy. As a part of these projects, it has provided expert and consultancy services focused on seismic evaluation of equipment and components, equipment qualification, structural mechanics, and more. As part of its projects, Rizzo Associates Czech used its GIP-VVER experience. Read on.

EQUIPMENT QUALIFICATION, MOCHOVCE NPP (SLOVAKIA)
