Developed by PHE, PACE is an application for performing probabilistic assessments of the off-site consequences of accidental release of radioactive material to the atmosphere (otherwise termed level-3 PSA) .
PACE (Probabilistic Accident Consequence Evaluation) is a tool for performing Level-3 Probabilistic Safety Analysis (PSA). Level-3 PSA is the evaluation of off-site consequences given a release of radioactive material to the atmosphere from a facility. PACE incorporates both a Gaussian dispersion model and the UK Met Office NAMEIII lagrangian particle model. PACE is embedded within the ArcGISTM Geographic Information System software enabling high quality map output to be produced.
