Microcomputer-Based Collateral-Effects Source Model for Hazardous Material Dispersal in Vent Plumes from Attacks on Hardened Structures

THE DEFENSE NUCLEAR AGENCY (DNA) IS DEVELOPING THE OPERATIONAL MESOSCALE ENVIRONMENT MODEL WITH GRID ADAPTIVITY (OMEGA) TO PREDICT REAL-TIME DISPERSAL OF HAZARDOUS AEROSOLS. ONE REQUIREMENT FOR OMEGA OR ANY SIMILAR MODEL IS TO PREDICT COLLATERAL EFFECTS FROM STRIKES ON NUCLEAR, BIOLOGICAL, AND CHEMICAL (NBC) FACILITIES. THE OBJECTIVE OF THE PROPOSED PHASE I PROGRAM IS TO DETERMINE THE ESSENTIAL FEATURES AND CAPABILITIES OF A MICROCOMPUTER-BASED COLLATERAL-EFFECTS SOURCE MODEL FOR HAZARDOUS MATERIALS CONTAINED IN VENT PLUMES PRODUCED BY ATTACKS ON HARDENED NBC FACILITIES. THE MODEL WILL INCLUDE THE EFFECTS OF THE FOLLOWING PARAMETERS ON THE DISTRIBUTION OF HAZARDOUS MATERIALS IN VENT PLUMES: WEAPON DESIGN INCLUDING EXPLOSIVE TYPE AND YIELD; TARGET DESIGN, COMPLEXITY, AND RESPONSIVENESS; PREEXISTING VENTS AND VENTS PRODUCED BY PENETRATING WEAPONS; THE INTERNAL DETONATION ENVIRONMENT; THE GROWTH AND DECAY OF VENT PLUMES; AND THE INITIAL DISPERSAL OF HAZARDOUS MATERIALS FROM THE STORAGE CONTAINERS INTO THE TARGET VOLUME. THE PRODUCTS OF PHASE I WILL BE SPECIFICATIONS FOR THE MODEL AND ASSOCIATED DOCUMENTATION, INCLUDING DESCRIPTIONS OF THE MODEL ARCHITECTURE, THE INPUT AND OUTPUT VARI- ABLES AND THEIR FORMATS, THE MODEL ALGORITHMS, AND THE REQUIRED COMPUTER HARDWARE AND SOFTWARE. THE COMPLETE MODEL WILL BE DEVELOPED DURING PHASE II.
