Abstract
Description
technical field
[0001] The invention relates to the improvement of the safety injection system structure of a nuclear power plant. Background technique
[0002] The safety injection system is also called the emergency core cooling system. Its main function is: when the primary circuit system of nuclear power equipment breaks and causes a loss of water accident, the safety injection system injects water into the core to ensure submersion and cooling of the core, prevent the core from melting, and maintain The integrity of the core; when the main steam pipe ruptures, the reactor coolant shrinks due to excessive cooling, the water level of the pressurizer drops, and the safety injection system injects high-concentration boron-containing water into the primary circuit to re-establish the water level of the pressurizer. Shut down the reactor quickly and prevent the reactor from returning to criticality due to supercooling.
[0003] In order to realize the above functions, the sa...
