Emergency Management and Risk Analysis for Hazardous Materials Transport • Shashi Nambisan • Professor of Civil Engineering • Dept of Civil & Environmental Engineering • Transportation Research Center • UNLV • Seminar at the • Dept. of Civil, Construction, and Environmental Engineering • Center for Transportation Research & Education • Iowa State University • November 5, 2004
Emergency Management • Disasters / Emergencies • Natural • Man Made • Epidemics
Natural Disasters • Earthquakes • Fires • Floods and Dam failures • Hurricanes / Tornadoes • Land slides / Mudslides • Volcanoes
Man Made Disasters • Accidental, Intentional • Chemical releases, spills • Explosions • Radioactive: power plant • Transportation: air, pipeline, road, rail, water • Fire
Emergency Management Phases • Preparedness • Response • Recovery • Mitigation Transportation is always a factor
Analyses to Support Emergency Management • Hazard Analysis • Risk Assessment • Vulnerability Assessment • Criticality Analysis
Key Terms • Susceptibility: How prone is a system to weaknesses • Vulnerability: The susceptibility to losses due to exposure to hazard • Reliability: The complement to vulnerability; describes adequate serviceability under the operating conditions encountered at a given time • Resiliency: The ability to recover to normal or near normal state of operations
Risk Assessment • Risk Assessment = f (Event, Probability, Consequence) • Probability of event “i”, Pi • Consequence of events, Ci • Risk of one event, Ri = Pi * Ci (?) • Other Models (Non-linear, Exponential, … ) • Risk of all events = S Ri ?
Vulnerability Assessment • Analysis of a system for weaknesses • Probability of an attack on the weaknesses • Factors • Ease of access • Ability and time required to “harden” the system / element
Criticality Considerations • Impacts on human life • Environmental impacts • Economic impacts • Duration of impact
Radioactive Materials Transport • Nuclear Waste Policy Act (1982) & Amendments • High Level Waste, Spent Nuclear Fuel • Routing Issues • Public Safety • Emergency Preparedness
Background • Nuclear Power / HLRW • Origins • 76 power plants • 4 DOE facilities • NWPA, NWPAA • Investigate Yucca Mountain as the Only Potential Site • Designated Yucca Mountain as THE repository site • Transport Modes: • Highway • Rail • Combination of Both
Transport Related Issues • Risk Analysis / Minimization • Population • Environment • Infrastructure • Emergency Response
Population • Resident • Non-Resident / Visitor • Resort Corridor • Proximity to I-15 and Union Pacific RR Track • ~100,000 hotel rooms • Special Populations • Schools • Hospitals, Health Care Facilities • Assisted Living Facilities • Prisons
Environmental Issues • F&F? • Plants & Animals • Habitats • Foraging Patterns • Migration Patterns • Endangered, Threatened, …
Infrastructure • Networks • Transport • Utility • Structural Adequacy • Carriage Way (Pavement / Track Structure) • Bridges, Tunnels • Functional Adequacy • Load • Geometrics (Clearances) • Impacts: Operations, Life Cycle Costs • System Safety • System Redundancy
Emergency Response: Performance Indicators (MOEs) • Incident assessment time • First responder time • First qualified responder time • Evacuation time • Extent of impact • Population and classes of population • Area (square miles, number of blocks, towns, cities) • Environment • Extent of “avoided” impact
Risk Assessment • Scenarios: • Routine Operations • Accident / Incident • Consequences • Radiological • Non-radiological • Identify all Events for Each Scenario • Estimate Pi and Ci; then Ri
Summary • Emergency Preparedness • Risk Assessment • SNF & HLW Transport • Population • Environment • Infrastructure • Emergency Response • Communications
