1 Rapid Risk Assessment Preparedness, Response, Recovery, and Mitigation Workshop U.S. Nuclear Regulatory Commission Rockville, Maryland Pacific Northwest National Laboratory November 15-17, 2005

2 2 TeamTeam Gariann Gelston (HERS), Project Manager Gene Whelan (NR), Technical Lead Dave Millard (ISE), EMAdvantage Lead Chitra Sivaraman (ISE) Tim Downing (ISE) Mitch Pelton (HERS), FRAMES Lead Dennis Strenge (HERS) Bonnie Hoopes (HERS) Tarang Khangaonkar (MSL), EFDC Lead Zhaoqing Yang (MSL) Cheegwan Lee (MSL) Lon Hachmeister (MSL) Mary Simpson/Joan Young (HERS), DS Lead

3 3 “Multi-Thematic” Modeling Supporters 1.Engineer Research & Development Center, ACOE 2.National Environmental Research Laboratory, ORD, EPA 3.Office of Nuclear Regulatory Research, NRC 4.Office of Radiation and Indoor Air, OAR, EPA 5.Office of Environmental Management, DOE 6.Pacific Northwest National Laboratory, DOE 7.Multimedia Modeling: $23M ($8M for FRAMES) 8.FEMIS/EMAdvantage: $42M

4 4 PurposePurpose Provide an illustrative example that combines a multi-thematic modeling capability with emergency planning & response tools to create an automated system, which provides a real-time linkage between scientific and emergency-response communities.

5 5 IntroductionIntroduction 1.Preparedness, Response, Recovery, & Mitigation a. Air is common b. Now easily link soil, surface water, groundwater, exposure pathway/routes, decision support, etc. c. Integrated Multi-thematic capability, illustrating water 2.Not Vaporware a. Simulated Sensor Data b. Pre-run 3-D surface water flow and transport c. Real site with real data d. Demonstration of actual software actually running

6 6 PropositionProposition 1.Release of an unknown contaminant, unknown strength, unknown location to a water body, where a nearby population is potentially exposed 2.Question: What is the potential impact to the surrounding area, and what response plan do you implement, if the contaminant levels are unacceptable? 3.Operate Status Board Command & Control system linked with “Multi-thematic Modeling” running in the background

7 7 Preparation Work 1.Spatial description of siteSpatial description of site 2.SensorsSensors 3.Contaminants of Concern (CoC) 4.Exposure scenarios/pathways per zoneExposure scenarios/pathways per zone 5.Fate & Transport Models (Calibrate/Validate) 6.Protective/Response Action Plans 7.Protective Action Thresholds and RecommendationsProtective Action Thresholds and Recommendations

8 8 Demonstration Steps 1.Operational System 2.Status Board notification through sensorsStatus Board notification through sensors 3.Incident IdentificationIncident Identification 4.Surface Water Back CalculationSurface Water Back Calculation 5.Surface Water Transport Forward CalculationSurface Water Transport Forward Calculation 6.Risk Impact AnalysisRisk Impact Analysis 7.Post Protective Action RecommendationsPost Protective Action Recommendations

9 9 Demonstration Steps (cont’d) 7.Choose and Implement best-fit Protective Action Plan 8.Evaluate differences between Protective Action Recommendations and Final Protective Action Decision 9.Re-evaluate in real-time as the assessment requires
