OREANDA-NEWS. November 16, 2012.  At Novovoronezh II (general designer and contractor – JSC Atomenergoproyekt, Moscow), there starts an appraisal of new welding procedure of the main circulation piping (MCP).

For the first time, together with the manual welding of the main circulation piping, there will be applied an automated argon-arc welding that will considerably improve the quality of welded joints.

It is planned that welding of the main circulation piping of Unit 1 will be carried out in December, which will become one of the highlights of this year at the site of NVO NPP II construction.

The main circulation piping connects the main equipment of the primary circuit (reactor, steam generators and primary coolant pumps) and is designed for the coolant circulation. Currently, NVO NPP II prepares to install two steam generators, and other equipment of the main circulation circuit has already been placed on the proper location.
