LOCA (Loss of Coolant Accident) Testing

LOCA (Loss of Coolant Accident) Testing

Nuclear reactors generate heat internally, to remove this heat and convert it into useful electrical power, a coolant system is used. If this coolant flow is reduced, or lost altogether, the nuclear reactor’s emergency shutdown system is designed to stop the fission chain reaction.

This is a term used in the nuclear industry to describe an event in which a nuclear reactor loses its coolant, which can lead to overheating and potentially serious consequences.

LOCA testing stands for “Loss-of-Coolant Accident testing.” It is a type of safety testing performed on nuclear power plant systems or accessories to assess their response to a loss of coolant accident, which is a severe hypothetical event in which the cooling capability of a nuclear reactor is compromised. LOCA testing is conducted to evaluate the behavior of safety systems and components under these extreme conditions.

LOCA, the term is used to describe an event in which a nuclear reactor loses its coolant, which can lead to overheating and potentially serious consequences.

Loss of Coolant Accident (LOCA) tests is an environmental qualification (EQ) process provide assurance that the equipment will continue to perform its intended safety function during and following a loss of coolant event.

RTRC Limited in collaboration with NPCIL (Nuclear Power Corporation of India Limited) has designed and developed LOCA (Loss of coolant accident) test facility in India for testing of the products to be used in Nuclear Reactor.
