Abstract

In the UK a new program to build nuclear power plants is commencing. In preparation Public Health England has developed a new Level 3 PSA code. The new tool called PACE incorporates advances in scientific understanding made since the last time such analysis was performed in the UK in the early 1990s. It also takes advantage of advances in computer technology including processing power, usability and specifically Geographic Information Systems. This allows PACE to utilize the spatial datasets of demographic, agricultural, economic and environmental attributes that are compiled and maintained nationally and internationally as well as incorporate a sophisticated though computationally intensive atmospheric dispersion model. PACE was implemented in the commercial GIS ArcGIS; this decision freed the developers to concentrate on the core modeling functionality and data compilation while PACE still benefits from powerful data handling and visualization capabilities, and provides the user with a flexible and modern user interface. PACE estimates public doses, numbers of stochastic and deterministic health effects and economic costs with and without mitigating countermeasures including sheltering, evacuation, stable iodine prophylaxis, relocation, food restriction and clean-up.
