The contract for supply of "Phoenix" radiation monitoring systems for three nuclear-powered icebreakers of Project 22220 was awarded to SPC "Doza"

The contract for supply of "Phoenix" radiation monitoring systems for three nuclear-powered icebreakers of Project 22220 was awarded to SPC "Doza"
LLC "Baltic Shipyard - Shipbuilding" has chosen SPC "Doza" as the supplier of radiation monitoring systems for the first-in-class nuclear-powered icebreaker and two next icebreakers in the series (Project 22220).

As part of the delivery of three radiation monitoring systems, SPC "Doza" also undertakes to develop the design and technological documentation, perform testing of RMS at proprietary test bench, provide installation supervision, commissioning and acceptance works. The company will also participate in the mooring and sea trials and in revision works after trials.

RMS "Phoenix" is designed for continuous measurement, collection, processing and storage of data, for performing tasks of the process radiation monitoring, area and contamination monitoring and personal dosimetry. The information is displayed on radiation monitoring panels and panels of the integrated marine automation system (IMAS), with generation of signals required to maintain the radiation exposure levels at the nuclear-powered ice-breaker in compliance with the Russian radiation safety standards (NRB-99/2009) for classes of operating conditions KS1–KS4, including the generation of "dry contact" signals to the IMAS to automatically shut down generators, if leakages was detected.

RMS receives information from measuring instruments and actuators, and processing of information at all levels the system.

RMS supports operation of the lower layer of the system independently of the upper level and operation of the entire system independently of its constituent parts within the agreed scope of radiation monitoring tasks in accordance with the single failure principle.

RMS provides data transfer to communication channels and access to the processed information via Ethernet network (TCP/IP protocol).

RMS component parts

RMS, which is an automated complex of software and hardware based on instrumentation and computer equipment – server, interconnection and control network based on Ethernet IEEE 802.3 standard, can be conditionally divided into four components:

  1. equipment for measuring radiation parameters, including process radiation monitoring, area and contamination monitoring and personal dosimetry – lower level;
  2. data exchange devices (BOP-1M - data processing and transfer units) between measuring devices of the lower level and software and hardware complex of upper level (SHC UL) – buffering data processing and transmission devices;
  3. computing equipment of upper level – means of server, interconnection and control network for collection, processing, storage and presentation of measuring, technological and related information to operators of radiation safety service – to displays, printers, external information channels and devices – upper level;
  4. power distribution units of RMS.

RMS "Phoenix" delivery due dates:

  1. for universal nuclear-powered icebreaker No.1– 30.09.16
  2. for universal nuclear-powered icebreaker No.2– 15.12.17
  3. for universal nuclear-powered icebreaker No.3– 15.12.18

About the nuclear-powered icebreakers

The nuclear-powered icebreaker of Project 22220 will be the largest and most powerful icebreaker in the world. Its length is 173.3 m, width – 34 m, design waterline draft – 10.5 m, minimum working draft – 8.55 m. The displacement is 33.54 thousand tons. The icebreaker has a two-reactor power plant the main steam source from a new generation reactor RITM-200 having capacity of 175 MW. The reactor was specially designed for this vessel.
The technical project of the nuclear-powered icebreaker was developed by CDB "Iceberg" in 2009. The variable draft hull design allows the icebreaker to be used equally effectively in Arctic Seas and at the mouths of polar rivers. It is planned that the icebreaker will operate in the Western sector of the Arctic: the Barents, Pechora and Kara Seas, as well as in shallow waters of the mouths of the Yenisei and Ob rivers.
On August 20, 2012 Baltic Shipyard has signed the contract for construction of LC-60 model icebreaker with the total cost of 37 billion rubles. Launching of the vessel is planned for November 2015, delivery to the customer – until the end of 2017.
