Introduction

• Lesson from Fukushima Daiichi accident -

Agency has new response role in case of nuclear or radiological emergency: Assessment of potential consequences and prognosis of likely emergency progression

IAEA

Roles of the IEC

• 1. Notification and official information exchange
• 2. Provision of assistance on request
• 3. Provision of public information
• 4. Assessment of potential emergency

consequences and prognosis of possible emergency progression

• 5. Coordination of inter-agency response

IEC Incident and Emergency Centre

IAEA

Feedback process for continual reassessment as the situation evolves and new information is learned Delivery mechanism of AP for MS, the media and the public Mechanism for resolving issues with the harmonized message Compilation of results and formation of harmonized message External support mechanism and process Initial assessment and prognosis Initiating process Nuclear or radiological emergency occurs in a State

Assessment and prognosis process - Summary

CA sends notification / advisory message to IAEA IEC IEC assesses and verifies initial information. IEC requests additional information needed for AP IEC performs AP using in-house expertise, capabilities and arrangements (through IES) IEC determines if external support is required IEC requests external support based on bilateral agreements with MS (preferably using RANET mechanism) IEC is provided with external AP support IEC combines results into a credible AP IEC discusses the AP with Accident State CA (and external support partners if they were involved) Is agreement reached to form a harmonized message? The matter is referred to the IAEA IES Steering Group for further steps IEC informs MS through proper channels and the public/media through MTPI As the situation develops and new information is received the IEC updates the AP following the same process Yes No Yes No Is the new AP substantially different from the previous AP? Yes No

IAEA

Technical Team

• Lead by Technical Team

Leader

• Will be an experienced IAEA staff

member

• Supported by subject matter

experts from all departments in house organized by technical background

• All received specialized IAEA specific

EPR training

IAEA

Radiation Safety Specialists

• Experts in radiation safety
• Variety of backgrounds (medical physics,

health physics, nuclear engineering etc.)

• Trained in tools and procedures for

assessing sources, conducting dose calculations, following IAEA EPR guidance

• TecDoc 1162, Generic procedures for

assessment and response during a radiological emergency

• TecDoc 1092, Generic procedures for

monitoring in a nuclear or radiological emergency

• Trained in examining offsite consequences

IAEA

Nuclear Security Specialist

• Experts in nuclear security
• Variety of backgrounds

(engineering, security, etc.)

• Trained to similar level as RSS

with different scope of responsibilities (focusing on security)

• Realistic security focused

exercises can be difficult to create

IAEA

Nuclear Installation Specialists

• Experts in nuclear installations

backgrounds mix of regulatory, operations in plant, etc.

• Responsible for reviewing information and

providing advice to ERM

• Training in tools, procedures and IAEA

EPR guidance:

• EPR-NPP, Actions to Protect the Public in an

Emergency due to Severe Conditions at a Light Water Reactor

• TecDoc 955, Generic assessment procedures for

determining protective actions during a reactor accident

IAEA

Approach to Development and Implementation of Tools and Procedures

• 1. Define the objectives of the process
• 2. Review existing capabilities and

arrangements

• 3. Develop the methodology to achieve the
• bjectives
• 4. Create the needed procedures and tools to

implement the methodology

• 5. Test, evaluate, improve

Procedures

IAEA

Procedures

These are long documents and only applicable for the environment in the IEC

IAEA

Assessment and Prognosis Tools

• The IEC has been developing and testing several

assessment tools

• Reactor Assessment Tool
• Environmental Monitoring Information Display System
• Radiological Source Assessment Tool
• Security Assessment Tool
• These tools have been used in various exercises

with Member States since 2013

IAEA

Reactor Assessment Tool

• Controls the reactor

assessment process

• f the Technical

Team working in the IEC

• User initially selects

type of reactor

• Specific instructions

for each type

• Custom visualization

depending on type

IAEA

Reactor Assessment Tool

Input form Visualization

IAEA

Reactor Assessment Tool

Instructions for each step of the process Includes details on what types of technical parameters and questions should be considered

IAEA

Reactor Assessment Tool

User selection immediately impacts the visualization

IAEA

Reactor Assessment Tool

• Rapidly produces

Reactor Status Assessment Report

• Each update

automatically saves a new time with time and date

• Each subsequent report

gets automatically saved as a new file and only requires a few fields to be updated

IAEA

Track and communicate accident evolution

IAEA

Reactor Assessment Tool

• Feedback has been positive
• Very easy to train and use for technical team

members in the IEC

• Quick to produce useful material for sharing with
• ther Member States in Status Summary Reports
• Improvements to user instructions are ongoing
• More emphasis on handling multi-unit accidents is

planned to be incorporated

• Currently finalizing version 1.0 (draft) ETA –

November 2016

IAEA

Reactor Assessment Tool (update)

IAEA

Reactor Assessment Tool (update)

• Currently doing internal testing
• Slightly more detailed than previous tool
• Feedback has been mostly positive
• Development is ongoing

IAEA

Radiological Source Assessment Tool

• User inputs number of sources, radionuclide

involved, activity and date of validity

• Tool automatically decay corrects for todays date

and performs calculations from EPR-D Values, RS- G-1.9 Categorization of Radioactive Sources and TecDoc-1192 (where applicable)

IAEA

Radiological Source Assessment Tool

Report contains current activity, category, dose rate and shielding information

IAEA

Mexico, Stolen Ir-192 source

• Example: Missing

Cat 2 source (50 Ci

• f Ir-192)
• In combination with

the ICSRS, produced a report within 5 minutes for internal use

IAEA

Environmental Monitoring Information Display System

IAEA

Environmental Monitoring Information Display System

• Capabilities include:
• Context information available for each data

point (e.g., distance to event location)

• Environmental Monitoring Information

Display System Report

• Access to different mapping solutions
• IRIX import feature
• Automatically create graphs of data

IAEA

Environmental Monitoring Information Display System

Quickly produce situational reports

IAEA

Environmental Monitoring Information Display System

IAEA

Environmental Monitoring Information Display System

This is now a backup tool

IAEA

International Radiation Monitoring Information System (IRMIS)

• Replaces EMIDS in the

Technical Team for handling data

• Far more robust system
• Available outside of the IAEA
• Handle large datasets of

monitoring information

• If you have access to USIE,

you should have IRMIS access

IAEA

Supporting Databases

• Static parameters for NPPs
• Technical data
• Diagrams
• Site data
• Dynamic parameters for

NPPs

• Critical safety functions
• Technology specific

IAEA

IAEA

Member State exercises

• These are our best
• pportunities to test

the process

• Need more
• pportunities in 2016
• Willing to participate

in exercises to test new procedures

IAEA

Technical Meeting on AP

• Technical Meeting to Review IAEA Assessment

and Prognosis Procedures for Nuclear and Radiological Emergencies

• 28 November – 2 December
• Draft assessment tools demo available
• Draft assessment procedures
• Discuss tools / procedures
• Review content and structure of automatic reports
• Discuss how to best involve Member State capabilities

to support the process
