How you benefit
UKAEA offers a range of modelling capabilities to address your particular needs. By combining modelling expertise with our experience in decommissioning and waste management, our specialist team delivers fit-for-purpose solutions, at an optimal level of detail and effort for your particular requirements. We can provide informed interpretation of the modelling results, draw appropriate conclusions and advise on the best course of action for your particular requirements. UKAEA has the experience and expertise to:
- Minimise costs using FISPACT modelling to calculate the activity and radionuclide inventory of a material for a given neutron flux and at selected cooling times
- Carry out dose rate and shielding modelling using both MicroShield and MCNP software for both simple and complex three-dimensional problems
- Optimise shielding designs to ensure selection of appropriate strategies early in the project lifecycle
- Model a reactor or facility to predict the neutron flux to components
- Model the impact on people of routine and continuous radioactive discharges to the environment using PC – CREAM software
