Hazard Prediction and Assessment Capability (HPAC)

Through version 3.2, HPAC has been a standalone Windows application with a GUI tightly coupled to a atmospheric dispersion calculation engine, SCIPUFF, developed by Titan/ARAP. The reengineering of the architecture began with version 3.2, in which Titan decoupled the calculation engine from the front end GUI. This early effort combined with a transition to Fortran 90 and use of module definitions has made possible the transition to a Web-based, distributed object, client-server architecture.

ORNL has contributed some parts in HPAC 4.0.

Advantages of using HPAC 4.0 insteaf of SCIPUFF are:

  • Built-in modules for contouring calculated dosage fields. We know the output of SCIPUFF has two formats: one is grid-based and the other is a set of puffs. However, HPAC can output contours as polygons, which can be easily shown on Google Earth. I have tested this part. And I also think puffs can be tranformed to polygons also, so results of SCIPUFF could also be displayed in Google Earth if we think this is a good illustration. We also have J-3D visualization for terrains and contours that are grid-based outputs of SCIPUFF. But in terms of ground texture, Google Earch is more realistic.
  • An extensive material libary with dosage values corresponding to the standard exposure levels. It also has radiation weapon model.
  • Built-in calculation of population using LandScan 2003 data

Other Issues

  • We have order equipments for the IPSN 2007 demo.
  • We are trying to request HPAC from DTRA
