Russian Firm to Equip Next‑Gen Icebreakers with “Phoenix” Radiation‑Monitoring Systems

Scientific Production Enterprise Doza has secured a contract to install its fifth‑generation “Phoenix” radiation‑control systems on Russia’s newest Project 22220 nuclear icebreakers, Leningrad and Stalingrad—further cementing Russian leadership in maritime nuclear safety

A Turnkey Solution for Nuclear Safety at Sea

Under a deal with United Shipbuilding Corporation’s flagship Baltiysky Zavod shipyard, NPP Doza will not only manufacture but also install, calibrate, and test its advanced radiation‑monitoring hardware aboard the 22220 icebreakers Leningrad and Stalingrad. Specialists from Doza will oversee both quayside and underway trials, ensuring seamless integration of the “Phoenix” system with each vessel’s control networks.

This end‑to‑end approach accelerates delivery timelines and reduces interface risks, giving operators confidence that every sensor, detector, and control console meets rigorous performance standards before the ships enter Arctic service.

Fifth‑Generation Innovation with No Global Equivalent

The “Phoenix” radiation‑control system represents Doza’s fifth generation of maritime monitoring technology. It provides continuous, real‑time surveillance of nuclear‑powered vessels and floating facilities, alerting crews instantly to any anomalies in ambient radiation levels. Already deployed successfully on the flagship icebreakers Arktika, Sibir, Ural, Yakutia, and Chukotka, Phoenix combines high‑sensitivity detectors with advanced data‑fusion algorithms to distinguish harmless background fluctuations from operationally significant events.

“Phoenix offers unmatched situational awareness,” says Ivan Kuznetsov, chief engineer at NPP Doza. “Our system not only detects deviations but also predicts trends, empowering crews to take preventive measures before thresholds are ever breached.”

By minimizing false alarms and automating data analysis, ship operators can focus on core navigation and logistical tasks, enhancing overall safety without adding crew workload.

Scaling Expertise to Floating Nuclear Plants

Simultaneously, Doza is finalizing Phoenix installations on the modernized floating nuclear power unit of Project 20871. This parallel rollout underscores the company’s dominant position in crafting high‑technology solutions for Russia’s nuclear sector. As more vessels and offshore platforms adopt Phoenix, stakeholders benefit from standardized training, streamlined maintenance, and interoperable data archives—ultimately reducing lifecycle costs and bolstering public confidence in nuclear propulsion and power generation at sea.
