Original Equipment Manufacturers' OEM Protective Coating Design Basis Accident Testing

Nuclear Energy Agency

The United States Nuclear Regulatory Commission (USNRC) currently holds the position that 100 percent of design basis accident (DBA) unqualified coating materials located within a pressurised water reactor (PWR) containment will fail (disbond) during a DBA (e.g. loss of coolant, main steam line break) and may contribute to the emergency core cooling system (ECCS) sump debris source term [1]. Electrical cabinets, small cranes, electric motors, pipe support components, and other miscellaneous equipment installed within US PWR containments are often coated by the original equipment manufacturers (OEM) using DBA unqualified coating materials (usually a standard shop ...
