Russian nuclear company Rosatom has obtained regulatory approval for the primary 3D-printed part of an RITM-200 small modular reactor plant. The part, a terminal field, was produced by the Afrikantov Experimental Design Bureau of Mechanical Engineering and has obtained certification from the Russian Maritime Register of Transport.
RITM-200 reactors are presently utilized in Russia’s nuclear icebreakers and function the muse for the nation’s deliberate floating and land-based small modular reactor crops. The prototypes accomplished complete testing earlier than receiving regulatory approval, in accordance with Rosatom.
Yuri Vytnov, Chief Technologist at Afrikantov OKBM, mentioned: “Acquiring regulatory documentation for the primary factor for the RITM-200 reactor plant manufactured with using additive applied sciences makes it doable to copy 3D printing know-how sooner or later to create varied gear for marine nuclear energy crops, in addition to nuclear business gear of different sorts and functions,”
This marks the primary time Russia has used 3D printing know-how for reactor elements, although the nation has beforehand employed additive manufacturing for take a look at gear and course of tooling. Ilya Kavelashvili, Director of the Additive Applied sciences Enterprise Unit at Rosatom’s Gasoline Division, mentioned: “Using 3D printing opens up new prospects for design and manufacturing. Elements with optimised geometry and improved traits could be created. This enables for elevated effectivity and reliability of the gear, in addition to a discount in weight and price.”
The nuclear business has more and more adopted 3D printing know-how in recent times. Earlier functions embrace a 3D-printed impeller put in at a Slovenian reactor in 2017, channel fasteners put in by Oak Ridge Nationwide Laboratory in a U.S. reactor in 2021, and a chrome steel gas part put in by Framatome at Sweden’s Forsmark nuclear energy plant in 2022.
Russia joins a number of different international locations, together with South Korea and the UK, in utilizing additive manufacturing for nuclear business functions. The Worldwide Atomic Vitality Company has recognized important potential for 3D printing know-how within the nuclear vitality sector.
