Atomenergomash sets up first RITM-200 reactor plant

ZiO-Podolsk JSC, a part of Atomenergomash JSC, a machine-building division of Rosatom State Corporation, has started welding the first girth seam on the half-vessel of the first RITM-200 reactor plant for Chukotka, the fourth serial new-generation nuclear-powered icebreaker.

The first main girth seam will connect the flange and the shell, which are two parts of the reactor vessel. The welding process is performed continuously for 5 days, in three shifts and with the metal being constantly heated to 200 degrees. The girth seam will have 2.8 m diameter and be 150 mm thick. This welded joint will belong to the category 1 seams, so it will be subject to the most stringent requirements during subsequent quality control.
