Russia is all set to ship the primary batch of 26 turbine corridor pipeline valves, completely weighing about 27.50 tonnes, for the Kudankulam Nuclear Power Project’s (KKNPP) reactors 5 and 6.

 These specifically designed valves can face up to temperature as much as 350 levels Celsius.

Russian State Atomic Energy Corporation, Rosatom’s machine-building plant Petrozavodskmash is delivery the turbine corridor pipeline valves to KKNPP, the place 2 X 1,000 MWe VVER reactors constructed with Russian technical knowhow are producing energy whereas 4 extra reactors with comparable capability are beneath development.

Currently shipped high-pressure and low-pressure gate valves are designed for set up within the turbine corridor of the nuclear energy plant. The key operate of the shipped gadgets is a decent shutoff of the fluid or gasoline circulation to make sure dependable operation of the system. During the manufacture, every bit of apparatus has been subjected to a set of manufacturing facility checks together with pneumatic, hydraulic and tightness checks. The pipeline valves are distinguished by a excessive class of tightness, which is confirmed by life checks beneath working parameters in testing laboratories accredited by the Rosatom State Atomic Energy Corporation.

The valves are being transported from Petrozavodskmash’s manufacturing website to the Great Port of St. Petersburg by highway from the place the gear will attain KKNPP website by sea. Similar pipeline valves of Petrozavodsk have been put in in reactor and turbine halls of the Leningrad Nuclear Power Plant and the Belarusian Nuclear Power Plant.

Tiny components

These valves are utilized in piping methods to watch and management the circulation of fluids or gases. In comparability with the primary gear of the reactor corridor, these components appear to be tiny as they weigh from 30 kg to five tonnes. At the identical time, they’re important for functioning of a giant system of the nuclear energy plant, a senior Rosatom official mentioned. “Equipment supplies for reactors 3 and 4 have almost been finished,” the official knowledgeable.

The Nuclear Power Corporation of India Limited (NPCIL), whereas working the primary two reactors of KKNPP, is actively engaged in developing reactors 3 to six and therefore the put in capability of this nuclear park will probably be 6,000 MWe when all six models begin energy era.

 Rosatom has agreed to produce gas to the ability models of the KKNPP all through their life.
