Steam and feedwater piping assessment outside the containment at Metsamor NPP
Original language description
In this paper, experience and results of the Pipe integrity design project applied to Unit 2 of Armenian NPP in Metsamor are presented. The feedwater and steam piping lines, which were covered by the Project, are located in the turbine hall on the elevation of +14.7 m, outside the containment. Piping was assessed from point of view of both pipe rupture postulation criteria defined in SRP 3..6.2 [2] and in BTP 3.4 [4] and seismic margin requirements [5] based on the international practice for the NPPs inoperation. Concerning hydrodynamic calculations, possible causes of steam and water hammer were assessed. To lower the stresses in critical locations and to solve the effects of steam/feedwater/emergency feedwater pipe whip, some measures have been proposed installations of whip restraints, hydraulic snubbers, etc. Detailed design files have been prepared for the proposed measures. Within this project, ISI program was conducted, with application to the most loaded locations. Proposal of
