The “Phoenix” radiation monitoring system allows not only to monitor the radiation background on the ship, but also to carry out individual dosimetric monitoring of personnel.

Modern nuclear icebreakers are equipped with an automated radiation control system created in the capital. The development is called “Phoenix”. It was created at the Doza Research and Production Enterprise (NPP) in Zelenograd.

The system has already been installed on the new nuclear-powered icebreaker Sibir. She continuously monitors the radiation situation on the ship. This was told by the head of the Department of Investment and Industrial Policy of the city of Moscow Alexander Prokhorov.

Phoenix consists of innovative instruments and detectors of various types of radiation. Both radiation (at 120 points of the vessel) and non-radiation (at 100 points) parameters are monitored. The system allows not only to monitor the radiation background on the icebreaker, but also to determine the cleanliness of the skin and overalls, as well as to carry out individual dosimetric control of personnel.

Icebreaker “Siberia” of project 22220 completed tests in the water area of ​​the Gulf of Finland. Today the nuclear-powered icebreakers of this project are the most powerful in the world. 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 navigate convoys of ships in arctic conditions, breaking through ice up to three meters thick.

“The industrial enterprises of the city develop and manufacture high-tech products that find their application in various fields: from the latest materials for the construction industry to advanced developments in the field of robotics and control and measuring equipment. These products are competitive and are in demand not only in our country, but also abroad. Thus, the equipment of NPP Doza is purchased by China, Turkey, Pakistan, France, Latvia and Greece. For example, Greece has purchased equipment for monitoring seismic activity, which will be supplied to the Athens National Observatory, ”said the head of the department.

In the course of the tests, Doza specialists checked the performance of the Phoenix complex under various operating modes of the reactor facilities, and also trained the icebreaker crew members to work with the new equipment and maintain it.

According to the general director of the company, Alexei Nurlybaev, the construction of these large icebreakers is carried out at the Baltic Shipyard, and the engineers and developers involved in the project often visit the ships and take part in the tests.

Previously, the company’s radiation monitoring system was installed on the lead nuclear-powered ship of project 22220 – the icebreaker “Arktika”, and now “Phoenix” provides full radiation monitoring of dosimetric and technological parameters of the vessel, which has already been put into operation. Another such system will operate at Ural, the third icebreaker of the project, which is currently under construction.

The Russian icebreaker fleet has recently 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 measures, as well as constant monitoring so that neither the crew nor the environment is harmed.

NPP Doza is a Russian developer and manufacturer of radiation monitoring systems. The equipment of the enterprise is in demand in all areas of activity related to ionizing radiation. Among them – nuclear energy, industry, medicine, environmental monitoring, security, as well as scientific research.
