Haiyang Unit 1’s CA01 successfully installed

The CA01, the most critical structural module in NI of Haiyang Unit 1, has been successfully installed. This is another major milestone after the Unit 2 CI FCD in late September this year.The State Nuclear Power Technology Corporation celebrated the lift and emplacement of the central 'CA01' module only around one year after the official start of construction. The module will contain main components including the reactor pressure vessel and two steam generators within the reactor building. The process to move the 841-tonne module took six hours and required the use of a very large twin-boom crawler crane, itself weighing 2000 tonnes not including counterweights.The T-shaped CA01 is also the largest and most complicated structural module in construction. Comprised of 47 sub-modules and weighing 1053 tons, it is mainly used to form structural rooms and accommodate such key equipment as pressure vessel.
