A loss-of-coolant accident (LOCA) is a mode of failure for a nuclear reactor; if not managed effectively, the results of a LOCA could result in reactor core damage. Each nuclear plant's emergency core cooling system (ECCS) exists specifically to deal with a LOCA. Nuclear reactors generate heat internally; to remove this heat and convert it into ...
A nuclear reactor coolant is a coolant in a nuclear reactor used to remove heat from the nuclear reactor core and transfer it to electrical generators and the environment. Frequently, a chain of two coolant loops are used because the primary coolant loop takes on short-term radioactivity from the reactor.
The China syndrome (loss-of-coolant accident) is a nuclear reactor operations accident characterized by the severe meltdown of the core components of the reactor, which then burn through the containment vessel and the housing building, then (figuratively) through the crust and body of the Earth until reaching the opposite end, presumed to be in ...
A loss-of-pressure-control accident (LOPA) is a mode of failure for a nuclear reactor that involves the pressure of the confined coolant falling below specification. [1] Most commercial types of nuclear reactor use a pressure vessel to maintain pressure in the reactor plant.
The Mayo Clinic diet is a diet plan formulated by the doctors of Mayo Clinic, ... and legumes will mean more fiber which may cause some gas and discomfort. “So, make sure you are drinking enough ...
The Mayo Clinic diet has two phases during which you can lose up to 10 pounds in two weeks. Here's what to know about it, including the Mayo Clinic Diet menu.
Failure to remove decay heat may cause the reactor core temperature to rise to dangerous levels and has caused nuclear accidents. The heat removal is usually achieved through several redundant and diverse systems, and the heat is often dissipated to an 'ultimate heat sink' which has a large capacity and requires no active power, though this ...
Pickering nuclear Reactor 2, Pickering, Ontario, Canada: LOCA loss of coolant accident. Pressure tube, that holds the fuel bundles, ruptured due to hydriding. All four reactors re-tubed with new materials (Zr-2.5%Nb) over ten years. [24] 0: 1 billion Canadian dollars (1983-1993). [25] March 1986: Bruce nuclear Reactor 2, Bruce County, Ontario ...
