Moscow enterprise supplied radiation control equipment for the Sibir nuclear icebreaker

2021: Application of the Phoenix automated radiation monitoring system in tests of the Sibir nuclear icebreaker

The equipment of the capital's enterprise NPP "Dose" is involved in sea tests of the atomic icebreaker "Siberia." The Phoenix automated radiation control system developed by the company in marine design continuously monitors the radiation parameters of the vessel's reactors, the Dozod NPP reported on December 2, 2021.

Atomic icebreaker "Siberia"

The Sibir icebreaker of project 22220 (operated by FSUE Atomflot of Rosatom State Corporation) completed sea trials in the Gulf of Finland. The displacement of each vessel is 33.5 thousand tons, the length is 173.3 meters, and the width is 34 meters. Icebreakers will be able to conduct caravans of ships in Arctic conditions, breaking through ice up to three meters thick.

"Industrial enterprises of the city develop and produce high-tech products that are used in various fields: from the latest materials for the construction industry to advanced developments in the field of robotics and instrumentation. These products are competitive and in demand not only in our country, but also abroad. So, the equipment of the NPP "Dose" is purchased by China, Turkey, Pakistan, France, Latvia and Greece. The latter, for example, acquired equipment for monitoring seismic activity, which will be delivered to the Athens National Observatory, "said Alexander Prokhorov, head of the Department of Investment and Industrial Policy of Moscow.

During the tests, specialists of the Dozod NPP check the operability of the Phoenix complex under various operating modes of reactor plants, as well as train icebreaker crew members to work with and maintain new equipment.

Earlier, the company's radiation control system was installed on the head nuclear ship of project 22220 - the Arctic icebreaker, and now Phoenix provides full radiation control of the dosimetric and technological parameters of the vessel, which has already been commissioned. Another radiation control system will work on the third icebreaker of the project - Ural, which is only under construction. Recently, the Russian icebreaker fleet has been replenished with ships operating on nuclear energy - this is a more environmentally friendly and powerful source of energy compared to traditional hydrocarbon ones. However, nuclear reactors installed on icebreakers require compliance with all necessary safety requirements, as well as constant control so that neither the crew nor the environment is affected. It is this problem that the Phoenix system solves, explained in the NCP "Dose."

"Working with icebreakers is one of the most exciting areas for us with interesting and non-standard tasks, unusual construction. The Russian nuclear fleet is an unprecedented scale. Whoever has ever seen a nuclear vessel with his own eyes will understand what I'm talking about. The construction of the largest icebreakers in the world is carried out at the Baltic Plant, our engineers and developers involved in the project often visit icebreakers and take part in the tests. Baltic Plant and Atomflot are customers with whom it is nice to work. This is a long-term cooperation, which began in 2005, when the first ARMS Phoenix was put on the icebreaker "50 years of victory," said Alexey Nurlybaev, Director General of the NPP Dozov.

Phoenix includes devices and detectors of various types of radiation. Both radiation (in 120 points of the vessel) and non-radiation (in 100 points of the vessel) parameters are monitored. The system allows not only to monitor the radiation background on the icebreaker, but also to determine the purity of the skin and workwear, as well as to conduct individual dosimetric control of personnel.
