All-round information-managing system ar im

AR IM system is designed to monitor radiation and chemical environment for providing safety and casualty control of ships.

System performs the following functions:

a) main:

• measurement of ionizing radiation levels and different mediums and providing with measurements results;
• measurement of components concentration in air and providing with measurements results;
• measurement of personal doses from external exposure and incorporation of radioactive materials (individual radiation control) and providing with measurements results;
• alarming if threshold values are exceeded;
• radiation environment emergency control;
• providing with summarized and detailed information about object’s status.

b) additional:

• solving of calculated-analytic problems and generating advice signals at the systems’ boards and panel;
• automated generating of command signals to turn on alarm and managing devices;
• storage and documentation of measured parameters and summarized information;
• generating command signals to turn off unsealed steam generators;
• generating command signals to manage oxygen distributor;
• providing operator with advice and recommendations in case of emergency (decision support system).     

AR IM specifications

• Automated continuous remote monitoring of radiation, air and dosimetric environment and microclimate parameters with total control volume of up to 256 channels;
• Automated shutdown of unsealed steam generators elements;;
• Individual dosimetric control of external and internal exposure, solving problems of personnel dosimetric forecasting in the range from 0,1 to 1500 sGy for gamma-dosimeters and from 50 to 3000 sGy for beta-dosimeters;
• solving of calculated-analytic problems according to set-up parameters (the core status forecast, personnel performance evaluation, etc.)
• solving of tactical tasks related to protection against weapons of mass destruction;
• emergency control of radiation environment through three channels of radiation monitoring in the range from 1 to 10 000 R/h;
• automated turn off of alarm units in external systems according to the results of radiation, technological, dosimetric and air monitoring and monitoring of microclimate parameters;
• receiving and processing of the data about reactor power at a time in the range from 0 to 125%;
• alarming when up to 4 threshold values are exceeded over any control channel of the system;
• automated codes input of measured individual body and skin external radiation doses, individual internal radiation doses, automated summing and storage of doses for the crew.
• AR IM system performs under:
       – Ambient temperature – from 0 to 45;^оС;
       – Relative humidity – up to 98% when temperature is 50^оС.
• System is supplied with 220V voltage of 50/400 Hz frequency
• Input power – 220V, 50/400 Hz – 1600VA.
• Possibility of failure-free operation throughout 5000 hours of continuous working is not less than 0,97 upon alarm function and not less than 0,99 upon management function.
• Systems’ lifetime till midlife repair – 12 years.
• Specified lifetime – 25 years.
• Specified operation time and lifetime are provided without resource constraints.

* Gas-analyzers are not supplied with the set

Gas analyzers connected to AR IM

AR IM composition

• The system has three-level hierarchy and is designed on block-modular principle.
• The first level comprises initial information sources: detection units (devices) (DU), gas-analyzers (GA).
• The second level comprises information preprocessing devices:information-processing device UNO-184S, ,instruction control unit ICU-05S ,set of individual thermoluminescent dosimeters KID-08SM3 ,radiometric device RIG-02SM
• The third level comprises panel equipment:control panel UNO-182S, ,doctor panel UI-149SM ,display USS-19SM ,multiplexer USS-16SM ,relay box UKK-52S information-measuring display UITS-02SM

AR IM operation

• Information from DU and GA goes to UNO-184S and ICU-05S devices that process information, compare with threshold values, manage and monitor DU and GA working capacity, generate and transmit information to the systems’ panel equipment: panels UNO-182S and UI-149SM through standard transfer channels RS-485.
• Panels UNO-182S and UI-149SM solve estimated-analytic problems by defined algorithms, submit information in sole layout through each measurement channel in graphical and text form, in generalized layout in signal-advice and operator action recommendations forms, record and archive information in normal situation and emergency.
• The system can be designed (on planner demand) according to both radial (“star”-type) and trunk schemes
