Japan’s Nuclear Regulation Authority (NRA) has concluded that domestically produced nuclear power plant components are sufficiently strong for their intended purpose. The country’s 11 nuclear generating companies conducted investigations after anomalies were discovered in equipment manufactured at France’s Le Creusot forge. That discovery raised concerns that forged steel components made by the Japan Casting & Forging Corporation (JCFC) for use at the Flamanville 3 EPR could contain similar anomalies. According to the Japan Atomic Industrial Forum (JAIF), the NRA decided this week to accept the companies’ findings that the JCFC-manufactured equipment in place at their plants was sufficiently strong. It said it was “unlikely that any of the products” used by the 11 companies in their plants “contained carbon concentrations higher than prescribed limits” for safety-related systems. The NRA thus concluded there was no possibility of “weaker-than-expected performance” of such products in any Japanese nuclear power plant.
