Siting Studies

Siting Studies

RIZZO has extensive experience in performing the necessary first steps of identifying potential sites through site characterization for a Nuclear Power Plant (NPP) in accordance with a number of U.S. and International Regulations and guidance. Working since 1984 in the worldwide commercial nuclear power industry, we have a proven record of accomplishment in supporting the establishment of a viable nuclear program. RIZZO provided integrated research, review, and subject matter experts, for the investigation for suitable sites for the location of a nuclear power plant.


RIZZO’s approach to conducting a detailed siting study or analysis utilizes published guidance but is customized to fit locales where background information can be limited. During this process we identify geotechnical/hydrological and environmentally preferable sites for the construction and operation of an NPP. RIZZO’s site selection approach is drawn from the EPRI Siting Guide, and USNRC and IAEA guidance. A proven criteria and ranking methodology is used to screen and discriminate locations for siting plants.

RIZZO has performed strategic siting studies for a number of utilities and governments around the world, routinely providing siting guidance through the process. Our firm is well versed in the particular siting nuances of major NPP vendors and provides guidance to our client as to which site is more amenable to the selected vendor’s design. RIZZO supports Design Certification, ESP, SAR, and COLapplications in the context of SAR Chapter 2, and the Environmental Report.
