Manufacture and tests of multilevel bellows expansion joint for BN-1200 RP steam generator vessel
The paper deals with the design features and manufacture of a multilevel bellows expansion joint for steam generator (SG) vessel of sodium-cooled fast reactor plant BN-1200. The steam generator manufacturing process, strength tests and their results are shown. In the paper issues are considered regarding calculation-based strength analysis of the bellows and verification of their operability under operating conditions as a part of BN-1200 SG vessel.
