Analysis of the Introduction,Flipping,and Hoisting Process for Lower Internal Components of the"Hualong 1"Reactor
This work mainly studies the processes of introduction,flipping,and hoisting of lower internal components of the first reactor of Fuqing"Hualong No.1".By comparing the structural differences and installation processes between the"Hualong No.1"reactor building and existing nuclear power reactors in China,the technical difficulties in introduction method,flipping position determination,flipping area layout,and installation of anti rollover devices of the lower internal components are proposed.Based on the above difficulties,investigation is conducted using methods such as comparative a-nalysis,theoretical accounting,and force calculation to demonstrate the rationality and reliability of corresponding coun-termeasures.
