IAEA

Terminology

• Predisposal

• Any waste management steps carried out prior to disposal,

such as pretreatment, treatment, conditioning, storage and

transport activities

• Safety Assessment

• the assessment of all aspects of a practice that are

relevant to protection and safety. This includes siting,

design and operation of a storage or disposal facility.

• Safety assessment is the systematic process that is

carried out throughout the lifetime of the facility or activity

to ensure that all the relevant safety requirements are met

by the proposed (or actual) design.

IAEA

Terminology

• Safety Case

• The SC is an integration of arguments and evidence that

describe, quantify and substantiate the safety, and the

level of confidence in the safety, of the radioactive waste

facility.

The acceptability of a facility for particular waste types will

depend on the arguments in the safety case about the site and

the facility engineering, the results of safety assessment and the

management arrangements to assure quality in all aspects of

safety-related work.

IAEA

A Brief History

• SADRWMS Project (2004-2010) • International Project on Safety Assessment Driving

Radioactive Waste Management Solutions

• Purpose • SADRWMS was an IAEA program of work designed

to examine the application of safety assessment

methodology to predisposal waste management

practices and facilities including waste storage.

• It complements the experience gained with the

IAEA’s projects ISAM completed in 2000, and ASAM

completed in 2007.

IAEA

A Brief History

• SADRWMS Project (2004-2010) • Main Objectives

In comparing international approaches to safety

assessment in the predisposal management of

radioactive waste, the SADRWMS objective was to

improve and harmonize such approaches and

methodologies.

• Scope encompassed all types of radioactive waste including

disused sources, small volumes, operational waste and

spent fuel, legacy and decommissioning waste, and

large volume NORM residues.

IAEA

A Brief History

• SADRWMS Project (2004-2010) • Outcomes

• A Safety Report document that describes the methodology for

safety assessment of predisposal radioactive waste

management activities developed under the SADRWMS project.

• Input to a harmonized version of the safety guide DS284 “Safety

Case and Safety Assessment for Predisposal Radioactive

Waste Management Facilities and Activities” that includes the

framework and flowcharts developed within SADRWMS

• The SAFRAN software tool for applying safety assessment

methodology to predisposal radioactive waste management,

including user guide and tutorials

• The TINT Test Case Report, which documents the application of

the DS284 methodology and the SAFRAN tool on the TINT

Radioactive Waste Management Facility.

IAEA

A Brief History

• 6th and last Plenary Meeting of SADRWMS

(April 2010)

• It was agreed that the completion of complimentary

safety reports illustrating the use and application of the

DS284 methodology and the SAFRAN tool would be a

significant part of the follow up project.

• To oversee the development of these complimentary

safety reports, it was agreed to establish the

International Project on Complimentary Safety Reports,

Development and Application to Waste Management

Facilities (CRAFT).

IAEA

CRAFT Project

• Inception of CRAFT Project • 1st Plenary Meeting was held in May 2011

• Objective of CRAFT Project : The objective of the CRAFT project is to develop, by

2014, a report, containing illustrative guidance for

applying the methodology in DS284 to a range of

predisposal waste management facilities or activities

with links to the use of the SAFRAN tool, for the IAEA to

publish

IAEA

CRAFT Project

• Inception of CRAFT Project • Main objectives of the 1st Plenary Meeting:

• To develop the ToR for the CRAFT Project;

• To review the outcomes of the SADRWMS project

(Methodology Report, SAFRAN software tool);

• To review the results of the SADRWMS test cases

(TINT and Studsvik);

• To discuss the use of existing national facilities as

application cases in support of CRAFT project

activities.

IAEA

CRAFT Project

• Inception of CRAFT Project • Identification of CRAFT working groups:

• The plenary identified a number of work areas where

they saw a need to develop further guidance in

illustrating the application of the DS284 methodology

and the SAFRAN software tool.

• Three Working Groups were identified:

• processing facilities;

• long term storage facilities;

• existing storage facilities.

IAEA

CRAFT Project – Activities Performed

• Regional Workshop on Development of the Safety

Case and Safety Assessment for Predisposal

Management of Radioactive Waste - Stockholm

10th-14th October 2011

• This was a TC funded meeting managed under the CRAFT

umbrella.

• The aim was to identify a number of application cases that the

agency could support to produce the production of the illustrated

guidance requested by the WASSC to support DS284.

• Participants from twelve countries provided information about

relevant activities in their countries.

IAEA

CRAFT Project – Activities Performed

• Regional Workshop on Development of the Safety

Case and Safety Assessment for Predisposal

Management of Radioactive Waste - Stockholm

10th-14th October 2011

5 Working Groups looking at :

• the development of a safety case for processing and storage of waste produced from the decommissioning of a specific aspect of the Ignalina nuclear reactor in Lithuania.

• the development of a safety case for the storage of waste in Slovenia;

• the development of a safety case for processing of waste at the Vinca facility in Serbia.

• the safety case for the retrieval of buried waste at a RADON facility in Estonia and the retrieval of material in Russia.

• the regulatory requirements associated with DS284 and the application of the SAFRAN tool. It was noted that this group would expand as there were a number of other countries that were known to want to participate.

IAEA

CRAFT Project – Activities Performed

• Regional Workshop on Development of the Safety

Case and Safety Assessment for Predisposal

Management of Radioactive Waste - Stockholm

10th-14th October 2011

Over the week, 4 Terms of Reference were developed (the

waste processing and storage working group had a

common set of ToR):

• NPP

• RADON Facilities

• Storage and Processing

• Regulatory Review

IAEA

CRAFT Project – Activities Performed

• Regional Workshop on the Safety Case and
