Workshop AT&D modeling 2023

The workshop is organized by company ABmerit, Ltd., Slovakia as a part of research project funded by Slovak Government. 

The workshop is planned as a set of invited talks and discussion sessions on three Case Studies.

We hope that the invited talks and the Case Studies will enable us to build a very creative atmosphere, which will be a great enrichment for all participants.

Venue:  

Mountain Resort - Hotel Patria, Strbske Pleso, High Tatras, Slovakia

Start on May 31, 2023 at 14:00, End on June 02, 2023 at 17:30

Topics: 

• Urban transport and dispersion modelling
• CFD model applications for urban environment
• AT&D modelling in upper atmospheric layers; source terms
• Transport and dispersion of nuclear explosions at any elevation
• Earth Observation data, 3D building data
• Decision support ESTE for radiological and nuclear emergencies

Workshop Agenda - Talks: 

The workshop is planned as a set of invited talks and discussion sessions on three Case Studies. The list of talks is preliminary, it will be finalized later.

• Dr. Steve Hanna (Hanna Consultants, Kennebunkport, Maine, U.S., title will be specified later);
• Oscar Björnham (Swedish Defence Research Agency, Department for CBRN Security and Defence): title will be specified later
• Anna Wawrzynczak-Szaban, Sławomir Potempski, Piotr Kopka (Polish National Centre for Nuclear Research, Centre of Excellence MANHAZ): Localization of the airborne contaminant in the urban terrain with the hybrid stochastic artificial neural network system.
• Lois Huggett (UK Met Office, Atmospheric dispersion research and response group): title will be specified later
• Jozef Sabol (Department of Crisis Management, Police Academy of Czech Republic): Importance of adequate interpretation of modelling results in quantities reflecting related radiological risks.
• Ľudovít Lipták (ABmerit): AT&D modelling in urban environment, modelling in upper atmospheric layers; transport and dispersion after nuclear weapon explosion.
• Michal Marčišovský (ABmerit): Source terms in radiological dispersion device, source terms after nuclear weapon explosion.
• Eva Fojcíková (ABmerit): 3D Geodata for urban dispersion models.
• Monika Krpelanová (ABmerit): Source terms for severe accidents at nuclear power plants.
• Peter Čarný (ABmerit): Decision support for radiological and nuclear emergencies. Dosimetry models, age categories, urgent protective measures and measures in the field of agriculture. Radiological parameters required in the process of protective measures recommendations.

Interactive discussion of workshop participants on an applied approach to urban atmospheric dispersion modelling and radiological parameter modelling. And, subsequently, example of real calculation performed. Discussion on potential source term hypotheses and radionuclides. 3D data in urban environment. Wind field data in urban environment, discussion on approaches to urban wind field data management. Atmospheric Dispersion and Transfer models applied. Discussion on model parameters. Discussion on dosimetry models applied (exposure from air, from deposit, inhalation, deposit on walls, deposit on roofs, air activity in different levels above the ground, assessment of radiation doses to affected people). Discussion of the required time and the possibility of meeting the time requirements of a real emergency response. Discussion of outputs of modelling available to emergency responders.

Interactive discussion of workshop participants on the approach to large-scale atmospheric dispersion and modelling of an event with a fission or fusion nuclear device. Subsequently, an example of real calculation of dispersion and radiological consequences in the affected territories at great distances from the epicenter. Discussion on potential source terms. Discussion of the need for numerical weather forecast data at higher altitudes than is common for events at nuclear facilities on the ground. Discussion of AT&D models applied. Discussion on AT&D model parameters. Discussion of the outputs needed to manage the radiological response.

Interactive discussion of workshop participants on an approach to the source term assessment, atmospheric dispersion modelling and radiological parameters for implementation of protective measures. Subsequently, example of real calculation performed, from a nuclear event identification, through AT&D modelling, up to an assessment of the need of protective measures to population affected. Discussion of the source terms and attributes of the source terms from nuclear facilities. Discussion on input data to perform calculation of radiological consequences. Discussion of the need of meteorological data: Site measurements and numerical weather forecast. Discussion of AT&D models applied. Dosimetry models, age categories, urgent protective measures and measures in the field of agriculture. Discussion of outputs potentially available for management and control of protective measures as implemented by emergency responders.
