U.S. Improvements in
EPR after Fukushima
Daiichi Accident JILL ZUBAREV
U.S. DEPARTMENT OF ENERGY / NATIONAL NUCLEAR SECURITY ADMINISTRATION
8TH COMPETENT AUTHORITIES MEETING
JUNE 2016

DOE/NNSA Deployment to
Japan
March 14 – DOE/NNSA departs with 33 experts and
17,000 pounds of equipment
March 16 – DOE/NNSA arrives at Yokota Air Base
March 17 – First aerial surveys and field monitoring
March 22 – First aerial data published on DOE website
2
DOE/NNSA Assets Involved
Nuclear Incident Team (NIT) in Washington, DC
DOE/NNSA Consequence Management expertise on the US Agency for International Development Disaster Assistance Response Team (DART) in Tokyo
National Atmospheric Release Advisory Center (NARAC) at Lawrence Livermore National
Laboratory (LLNL)
Consequence Management Home Team (CMHT) at Remote Sensing Laboratory (RSL), Sandia National Laboratory (SNL), LLNL, and Los Alamos National Laboratory (LANL)
Radiation Emergency Assistance Center/Training Site (REAC/TS) in Oak Ridge, TN

What We Accomplished
Deployed for 2.5 months
Conducted 100 flights for a total of 525 flight hours
Collected 620 air samples, 250 in-situ spectra, and
141 soil samples
Logged 314,000 joint data points
4
DOE/NNSA Aerial Monitoring
What was done:
• Fixed wing and helicopter
• Up to 3 aircraft per day
• DOE & Japan joint survey
Why was it done:
• Map ground deposition out
to 80 km from FDNPP
• Support Humanitarian and
Disaster Relief Operations,
evacuation, relocation,
agricultural decisions
5
DOE/NNSA Ground Monitoring
What was done:
• Mobile mapping
• In-situ & exposure rate
• Air & soil sampling
• Contamination swipes
• DoD & Japan data aggregation
• Fixed sensor real-time network
Why was it done:
• Calibrate aerial measurements
• Define isotopic mix
• Characterize the inhalation component of integrated dose
• Assess vertical and horizontal
migration of deposited material

Instrumentation
Real-time monitoring
Mobile detection for Consequence Management
9
Infield Monitoring
System (IMS)
•An array of Sodium
Iodide radiation
detectors placed
at key location, as
identified by the
green dots, around
Fukushima Dai-ichi
•The IMS detects
changes in
radiation levels
•IMS continuously
monitored in real
time
Real-time Monitoring

Monitoring Results: Sendai to Tokyo 11
Analysis Methods
Evaluation of field measurement results
(aerial and ground)
Initial screening/reality check in the field
Further analysis by Home Team
Caution: You match models to measurements, not the other way around!
Trend analysis and quality control
12
Analysis Methods (continued)
Interpretation of real-world challenges posed by
multiple data sources
DOE, DoD, Japan
Lots of “What if?”
13
Data Presentation
“Its all about the data.”
But, you have to be able to explain it.

Training
2011:
•All personnel in a team received same training
•Need for some personnel with more problem-solving skills
2016:
•Tiered training
•(Type 1, 2, 3)
•(Incident Command System)
•More personnel available
•Less time burden for many
•Core group of higher level problem solvers
•More sustainable

Procedures
Know your mission!
“It’s all about the planning, not the plan.”
Be able to cope with challenges.
Be prepared for anything but be flexible.
Unified team.

Conclusion
Robust international cooperation and
collaborative efforts are key to
improving regional and global
emergency response capabilities.
THANK YOU!
