Strength Analysis for Equipment Gate of Nuclear Power Plants

In the operation condition and accident condition,the equipment gate in the nuclear power plants is closed and acts as the third shielding together with the reactor containment,to prevent the release of radioactive materials,and so it is one important part of containment pressure boundary.Based on the FEA method of ANSYS and RCC-M normative theory,a detailed stress calculation analysis is conducted for the equipment gate and its support components in nuclear power plants,and the result is in accordance with the RCC-M rule.The analysis method is reasonable and accepted by NNSA.
