Boiling Water Reactors - Technical and Background Information - Thermal Margins - Average Planar Linear Heat Generation Rate (APLHGR)
... The ECCS is designed to rapidly flood the reactor pressure vessel, spray water on the core itself, and sufficiently cool the reactor fuel in this event ... However, like any system, the ECCS has limits, in this case, to its cooling capacity, and there is a possibility that fuel could be designed that ... the decay heat stored in the fuel assemblies at any one time does not overwhelm the ECCS ...
RBMK - Reactor Design and Performance - ECCS
... The reactor is equipped with an emergency core cooling system (ECCS), consisting of dedicated water reserve tank, hydraulic accumulators, and pumps ... ECCS piping is integrated with the normal reactor cooling system ... In case of total loss of power, the ECCS pumps are supposed to be powered by the rotational momentum of the turbogenerator rotor for the time before the diesel generators come online ...
Nuclear Meltdown - Soviet Union-designed Reactors - VVER
... have been built with more than marginal containments, some have quality ECCS systems, and some have been upgraded to international standards of control and instrumentation ... Has no ECCS ... - rather than abandoning the reactors entirely - have opted to install an ECCS, develop standard procedures, and install proper instrumentation and control systems ...

Later versions which used ECCS engine management, discarded the twelve tiny runners for six much larger ones (though they retained twelve ports on the head, so there ... This had an improved head design, and used the ECCS injection system ...
Nuclear Meltdown - Light Water Reactors
... Failure of the Emergency Core Cooling System (ECCS) ... The ECCS is designed to rapidly cool the core and make it safe in the event of the maximum fault (the design basis accident) that nuclear regulators and plant engineers could imagine ... There are at least two copies of the ECCS built for every reactor ...
