  1. Adaptation and Installation of the software “TRACE_WIN” and “NOSTRADAMUS” Modeling airborne radiological dispersion and contamination for radiation hazardous facilities

  2. TRACE_WIN allows users to simulate, monitor, analyze, and map atmospheric radioactive releases using a GIS format

  3. TRACE_WIN The model, which the computer code based on, is designed for computation of atmospheric transport of pollution within a radius of 10 to 20 kilometers of the facility. The main advantages of the model are its simplicity and immediacy. The computation takes a few seconds so TRACE_WIN is used for initial (approximate) assessment of radiation situations

  4. NOSTRADAMUS: real time computer system for estimation of atmospheric transfer IBRAE developed a software package NOSTRADAMUS to analyze accidents of various scales. NOSTRADAMUS package was designed to effective forecast radiation situations with a release in aerosol and gaseous forms with subsequent precipitation

  5. NOSTRADAMUS code is based on a Lagrangian trajectory transport model • Comparing to the standard Gaussian models, this model features the following capabilities: • Calculation of contaminant transportation - up to hundreds of kilometers ; • Taking into account a real three-dimensional heterogeneity of wind field inside an atmospheric boundary layer ; • Calculation of soil depositions taking into account distribution of aerosol particles by size; • Taking into account fluctuations of source and meteorological parameters; • Taking into account landscape features; • Taking into account time period and coordinates of atmospheric precipitations.

  6. Computer system “NOSTRADAMUS” characteristics • PC oriented; • Friendly WINDOWS interface; • Forecast efficiency — real time calculations: one hour of real time transportation requires 1 - 2 minutes of computer time; • Presentation of calculation is easy to understand - based on geographical maps The “NOSTRADAMUS” system includes atmospheric boundary layer model for the recovery of wind speed field vertical structure and atmospheric stability class on the base of synoptic information. It makes possible to use different sources and volumes of meteorological data for calculation. Data of long-term observations on vertical profile of turbulent diffusion coefficients are used for the turbulent exchange coefficients calculation.

  7. Representation of Plume Propagation Process

  8. DOE-IBRAE Cooperation After the table-top exercise conducted at FSUE NIIAR on December 9, 2003, in the framework DOE-IBRAE cooperation, it was concluded that it was necessary to upgrade the software of local crisis centers of radiation hazardous Rosatom facilities for simulation of the consequences of radioactive releases at the early stage of accident evolution

  9. 2004 • FSUE SSC "Scientific and Research Institute of Nuclear Reactors" (NIIAR); • FSUE Siberian Chemical Combine (SCC); • FSUE Mining and Chemical combine (MCC); • FSUE PA "Mayak“

  10. 2005-2006 • FSUE PA Electric and Chemical Plant (ECP); • FSUE Ural Electric and Chemical Combine, (UECC); • FSUE Angarsk Electric Chemical Combine, (AECC)

  11. In 2006, TRACE_WIN and NOSTRADAMUS were successfully adapted to the specific features and installed at the following facilities related to decommissioning of the nuclear submarines and nuclear powered vessels in the North-West Region of Russia: • FSUE «ME «Zvezdochka» ; • FSUE «SRZ «Nerpa» - Shipyard «Nerpa»; • FSUE «Atomflot» 2006-2007

  12. Priargunsk Production Mining and Chemical Association (PPMCA, Krasnokamensk town, Chita Region); Chepetsk Mechanical Plant (ChMP, Glazov town, Udmurt Republic); Novosibirsk Plant of Chemical Concentrates (NPCC, Novosibirsk city) 2007Adaptation of "TRACE_WIN" and "NOSTRADAMUS" software for three radiation-hazardous facilities of Rosatom
