Russia Begins Producing ‘Vulkan’ Sensors for Nuclear Power Plants
A new generation of Russian-made, electricity‑free magnetic‑contact sensors is entering serial production, offering the nuclear industry a rugged tool for high‑pressure, high‑temperature pipeline monitoring
State corporation Rostec has announced that its subsidiary, the Rosel holding, has launched full‑scale production of magnetic‑contact reed sensors known as ‘Vulkan’. These stainless‑steel devices are engineered for use in high‑pressure steam pipelines as part of automation and signaling systems at nuclear power plants.
According to Sergey Maksimov, CEO of the Ryazan Plant of Metal‑Ceramic Instruments — Russia’s only facility manufacturing such sensors and part of Rosel — the technology marks a first for the nuclear sector.
The sensors operate without electrical power and withstand extreme temperatures of up to 350°C. They remain functional even under maximum‑design‑basis earthquakes and are rated for up to 5 billion actuations, with a service life of up to 12 years.
Maksimov added that strengthening Russia’s domestic component base is a strategic priority. The launch of serial production reinforces the country’s technological independence in critical industrial sectors.
