Abstract: The safety relief valve is a significant safety accessory for releasing a certain account of medium to protect pressurevessels, piping and other pressure containment equipment. Correct rated capacity calculation is the important step of safety relief valves selection and system protection design. Kinds of rated capacity calculation standards for the AP1000 nuclear projectsafety relief valves are analyzed and compared for the subsequent tests.
