SimER
SimER (Simulation of Environmental Risks) is a
powerful performance assessment code, developed by Nexia Solutions
with support from the Nuclear Decommissioning Authority (NDA). SimER can be
used to support decision making on site end states and management
strategies for sites at a level consistent with requirements for
regulatory submissions. Applications of SimER include contaminated land and waste disposal. A number of
components make
up SimER.
SimERs capabilities include:
- 3D groundwater flow (saturated and unsaturated conditions) and
contaminant transport (radioactive and non-radioactive).
- Representation of topographical details and geological
structures.
- Explicit climate and landscape change representation.
- 3D modelling of engineering and remediation options for
contaminated land sites.
- Assessment-level representation of biogeochemical reactions to
represent the chemical evolution of the system.
- Applicable to both radioactive and non-radioactive
contaminants.
- Calculation of a wide range of impacts, environmental risks and
doses over time.
Useful features include:
- Flexible inventories component - variety of waste forms
emplaced at different times or contaminated land.
- Multiple run capability allowing sensitivity studies and
probabilistic (stochastic) assessments.
- Flexible input language including unit checking.
- Built-in visualisation capability to display 3D views of model
output and plot graphs of parameters against time.
An illustrative SimER application is shown in the figure below.
