The St. Petersburg plant “Kirov-Energomash” (part of Rosatom) will manufacture valves for the turbine units of the nuclear icebreaker “Rossiya” (Project 10510 “Leader”), which is being built at the Zvezda Shipbuilding Complex in Primorsky Krai. The Russian Maritime Register of Shipping has issued a certificate for the equipment, confirming its safety and compliance with marine standards.

This refers to control valves for the PTU-74 steam turbine unit. The shut-off device ensures precise dosing and supply of steam to the turbine blades. It helps maintain the necessary rotational speed and turbine power in various operating modes.

PTU-74 is a modular automated marine steam turbine unit. It is being developed by specialists from the Kaluga Turbine Plant (KTZ, part of Rosatom's Machine-Building Division).

Project 10510 “Leader”

The lead nuclear icebreaker “Rossiya” of Project 10510 “Leader” will be the most powerful in the world (120 MW). The vessel will be able to break through ice more than 4 meters thick.

Unique equipment is being created from scratch for this project. The development of two RITM-400 type reactors is being carried out by JSC “OKBM Afrikantov”, and pipeline fittings by the “Armalit” plant. The localization level of key units and ship systems of the icebreaker exceeds 90%.
