On March 16, 2021, the Industrial Ruby marine vessel left the port of St. Petersburg with a batch of equipment for Kudankulam NPP that is under construction in India. This is the first of lot of equipment for Kudankulam Units 3 and 4 this year and the 24th under the project. The lot with 2173 cubic meters of equipment that was planned to be shipped was promptly loaded on the vessel. The 24th lot included air locks for passive heat removal system, pumping equipment, penetrations, valves, switchgear cabinets and pipelines. On the way to India, the vessel will call at the port of Hamburg to collect a batch of equipment that has been fabricated by European manufacturers and then will set course for India. Power units No 3,4 and 5,6 are the second and the third stages of Kudankulam NPP constructed under AES-92 design with VVER-1000 (V-412) reactor type. The technical solutions implemented in Kudankulam design characterize further evolutionary development of NPPs with VVER-reactors of high power and transition to creation of a new, reliable, safe and feasible power unit.New power units of Kudankulam NPP comply with the most up-to-date safety requirements of IAEA.
