Idaho National Laboratory (INL) Overview

INL is a US Department of Energy (US DOE) facility

History of reactor development, fuel reprocessing and nuclear research

Yearly monitoring requirements for the radionuclide Cs-137

Cs-137 is a fission product distributed in/on site soils

Business Problem

Measure at specific locations

Large Area to Monitor

Need to predict Cs-137 at

unmeasured areas

Dynamic Contamination

Patterns (wind, activities at

the site)

With thousands of acres, how can the monitoring be optimized

and defensible?

Data Business Needs

Use measured data to predict the Cs-137 values at

unmeasured locations across the site

Defendable to highest scientific level

Defend site baseline

Alleviate public concerns when trying to attract new missions

Compare post event release levels to radiological baseline

In emergencies, this data is the INL radiological baseline

condition

Previous INL Modeling Efforts

Ordinary Kriging

Standard Technique provided via

GeoStatistical Analyst

Not Robust Enough

Incorrectly predicted high Cs-137

(ground-truthed areas)

Results showed spatial gaps in error surfaces

Disjunctive Kriging with Declustering

Available via GeoStatistical Analyst

Declustering Method DID NOT reflect field

sampling conditions

Declustering by cell or polygon method was not accurate

Models underestimated variability of predicted values

INL Modeling Efforts – Why a new Approach?

Requirements for Predictive Modeling at INL:

Declustering by nearest neighbor techniques

Prediction surface with low uncertainties

Spatial dependencies across entire site

Environmental Parameters need to be used in predictions

Ability to defend DOE/INL positions regarding siting of new projects

Monitoring methods at or beyond EPA scientific protocols

More efficient and dynamic soil monitoring

Combine data from multiple years for predictions

State-of-the-Art defense for key environmental media

Provide a monitoring baseline necessary prior to any new large onsite projects

GeoPredict: Computational model created to best predict the

probability of something occurring…

GIS (Spatial Relationships)

GeoStatistics (Stan Miller)

Unique approach

to GeoEngineers

GeoPredict - What is it?

Archaeology, Contaminants, Environmental, Landslides, Weapons Caching, Human Terrain,

Earthquakes

Open and Scalable Solution Scientific Peer Reviewed Reusable Adaptable

ESRI GIS Application interface(Task Assistant Manager) Computational engine

GeoEngineers created a solution framework called GeoPredict

that leverages a number of data inputs displayed in a map output

GeoPredict - The Framework

GeoPredict – What Does it Look Like?• Very complicated science rolled into easy to use interface

Existing GIS DataPhysical Environmental

Elements

GeoPredict - Knowing the Parameters

•Bayesian:=P[(E1/A)(E2/A)(E3/A)(E4/A)(E5/A)]*P(A)

P[E1*E2*E3*E4*E5]

•Kriging with Exhaustive Secondary Information

Kriging with External Secondary Information

ESI = bayesian calculations based on environmental parameters

Kriging with ESI –

Includes environmental parameters (the external secondary information as Bayesian) known to be part of the contamination patterns (wind, soil, slope, etc.) combined with measured locations

Better predictions with lower errors (more confidence in the results)

What’s next? Additional modules, scalable, etc.

GeoPredict - Model Output
