A Summary of the Statement of Work (SOW) is as follows: 1.1 BACKGROUND- The Hazard Assessment Capability (HASCAL)/Second-order Closure Integrated PUFF (SCIPUFF) codes have been developed under DNA contract DNA001-94-C-0171 and in conjunction with Oak Ridge National Laboratory. HASCAL was an extension of the Radiation Assessment & Consequence (RASCAL) code used for emergency response for nuclear power plants in the Continental United States. HASCAL extended that capability to worldwide capability, and with a climatological data base for planning purposes. SCIPUFF was originally developed for the Electric Power Research Institute (EPRI) and extended by the Defense Nuclear Agency (DNA) for multiple nuclear dust clouds and recently for atmospheric transport of Nuclear, Biological, and Chemical materials. The atmospheric transport model in RASCAL and HASCAL has been replaced by SCIPUFF in HASCAL. These codes have become a key component of the Hazard Prediction & Assessment Capability (HPAC), which have now been delivered to users in the field as prototypes. SCIPUFF provides an efficient and accurate capability to simultaneously transport materials over multiple scales from local, regional, and continental if appropriate weather information is provided. This weather information could be climatological, observations or real time forecasts at various scales. SCIPUFF can accurately provide a sub-grid scale transport prediction deterministically and provide detailed effects at ground levels to overlay on the existing Geographic Information System (GIS). In addition to the accuracy and efficiency, SCIPUFF also provides a probabilistic solution due to the second-order turbulence formulation which provides variances for the atmospheric turbulence which can be used in two ways. First, the probability of exceeding a particular dose provides a useful result for a commander on the uncertainty due to atmospheric turbulence. Second, for planning, another solution can be obtained using climatological data at a site to show the probability of exceeding a particular lethal dose if the weather is not known or the planning is more than a few days in the future. The probabilities can be quantitatively provided in minutes on a PC computer as opposed to hours on a CRAY computer for typical Monte Carlo techniques. 1.2 OBJECTIVES- 1) Maintain and develop a baseline deterministic and probabilistic transport model for the HPAC for accurate and efficient local and long-range hazard predictions in complex weather conditions. 2) Provide or develop an efficient, mass-consistent, terrain responding wind field calculation option for HASCAL/SCIPUFF or equivalent capability. 3) Modify and extend HASCAL/SCIPUFF or equivalent capability to operate transparently over a spectrum of PC platforms including but not limited to a 486 PC. The model shall also be portable to CRAY, IBM RISC-6000, and SUN Sparc 20 computers. This will include but not be limited to a) modifications based on user feedback (improve flexibility and incorporate future enhancements into the Graphics User Interface (GUI) for example), b) additional source models (in particular, a source model for nuclear weapons and targets to include radiative decay, chemical weapons and targets to include secondary evaporation, and industrial targets with hazardous materials to include but not limited to dense gases), c) additional operational and remote meteorology data inputs, d) additional effects models for the additional source materials, and e) accommodation of Digital Terrain Elevation Data (DTED). 4) Accept a cloud model input or equivalent capability (being developed under DNA Contract, DNA001-C-94-0148/0149), and incorporate into the PC Windows and Geographic Information System (GIS). 5) Support validation efforts of the transport model for 20 cases around the world at different seasons. This shall include several interesting cases that stress current capabilities or support particular customer objectives. 6) Support semi-annual technical demonstrations in the field which will increase in complexity during the contract. This includes increased demands on data ingestion into the model due to data availability and increased resolution. These demonstrations must be conducted in real time under simulated operational conditions at a test range such as White Sands Missile Range. 7) Maintain configuration control of a baseline version of the model being used operationally while simultaneously developing extensions which can be delivered to users on a proto-typical basis, and later baselined.
