Tsuruga Fault Review

The Tsuruga nuclear power plant on the west coast of Japan lies close to a major active fault. Structures beneath the plant were asserted by the regulatory authorities to be active faults. A detailed geoscientific evaluation of the site challenged this assertion. MCM managed an independent international evaluation of the evidence and concluded that the faults beneath the plant were not active according to the regulator’s definition. This was a high-profile project requiring major public presentations and media conferences.
