General Tasks of ERC Analytical Group
ROLE OF ERC ANALYTICAL GROUP:
operative information and analytical support ERC emergency management
responsible for protection the public,
rescue personal and environment in case of radiological or nuclear accident
1. Information support:
- collection and processing all necessary data about accident from different information
sources (response initiator, source term database, meteorological provider etc.);
- using GIS to show accident object, place and around area, dose-rates and contaminated
data (if we have), dislocations our field emergency team units and other important
information;
- creating situation reports for ERC emergency management.
2. Analytical support:
- assess of emergency situation: define areas can be contaminated, estimate possible doserates and doses for the public, levels of contamination by special software codes and
prepared models of event;
- collaboration together with group of experts for create recommendations about necessary
protection action in form of report for ERC emergency management.

Technological scenario
failure of the primary
cooling circuit pipe work
LOCA, overheating
and melting of nuclear fuel inside
the reactor core
primary and secondary
containment remain intact
release into the atmosphere
small fraction of the

Meteorological Parameters
Inversion meteorological conditions,
characterised by stability category F and
a conservative wind speed of 1 m/s,
which associated with smallest
dispersion radioactive material in the
horizontal direction and are associated
with the highest radiological effects,
which potentially can get a person in the
cloud
