3. Objectives
Share regulatory experience amongst forum members preparing to license SMRs
Capture good practices and methods
Interact with key stakeholders
Propose changes, if necessary to requirements and regulatory practices
Kick-off meeting held in March 2015

5. Graded Approach Working Group
Developed a detailed survey for forum members on national approaches
Analyzed survey results and discussed common positions
Reviewed IAEA documents and considered recommendations
Regulators are either engaging or are preparing to engage with proponents who are preparing safety cases that will involve the use of SMR technologies. These proposals are being anticipated contain safety claims using novel approaches and technologies that will be based on alternate interpretations of existing regulatory requirements or present new safety approaches where regulatory requirements may not exist. This will require both the regulators and the regulated to consider applying a graded approach to confirm novel approaches or technologies being proposed will result in a level of safety commensurate with the risks presented by the proposed activities. The SMR Regulators’ Forum agreed that there is a need to clarify the regulatory view of grading and what this means in the context of addressing novel approaches being proposed for SMRs.
Refer to the Terms of Reference for the SMR Regulators’ Forum for a definition of SMR.
The starting point for WG discussions will be the IAEA definition of the term; however the survey will attempt to draw out differences from member states.

6. Graded Approach – Main Findings
Graded approach can enhance regulatory efficiency without compromising safety
Starting point for SMRs should be requirements for Nuclear Power Plants (NPPs)
Need to determine what is necessary to demonstrate “proven-ness”
IAEA should lead development of technical guidance on graded approach for NPPs

7. Defence-In-Depth Working Group
Identified key regulatory challenges with respect to DiD that may emerge in future SMR regulatory activities.
Also developed a detailed survey on national approaches
Analyzed survey results and unique features of SMRs
Objectives
Regarding the application of the concept of Defence-in-Depth to SMRs:
Share regulatory experience and views amongst Forum members.
Capture good practices and methods and strive to reach a common understanding.
Communicate the results of these discussions to the forum members.

8. Defence-in-Depth – Main Findings
Defence-in-depth (DiD)concept should be fundamental for design and safety demonstration of SMRs
SMRs raise questions regarding application of DiD in several areas
Further guidance to help safety assessment of DiD applied to SMRs is needed

9. EPZ Size Working Group
Established an understanding of each member’s regulatory views on EPZ size
Shared technical basis for EPZ size decision
Discussed what evidence SMRs would need to present to regulators to justify smaller EPZs
Objectives:
Share, document and disseminate the collection of the regulatory experiences for licensing and siting for EPZs among forum members.
Provide technology-neutral general principles for EPZs.
Provide suggestions for revisions to or for the development of new IAEA general requirements or safety guide documents relating to source terms, EPZ and emergency preparedness. Examples of the documents that may be reviewed are:
SSR-2/1 GS-R-2 SSG-16
SSR-2/2 GS-G-2.1 NS-R-3  
Provide suggestions for changes to international codes and standards.
Identify cross-cutting issues that may exist among the DiD, Graded Approach and EPZ Size working groups.
 May not need a list of documents. Consider Deleting.

10. EPZ – Main Findings EPZ is required but may be scalable
Novel features and technology
IAEA safety requirements and methodology for EPZ size are applicable
Same SMR design may result in different EPZ size in different countries
Dose criteria
Policy factors
Public acceptance

11. Pilot Project Report Summarize accomplishments of the Forum
Common positions
Working Group reports
Recommendations for future activities
Will be published as IAEA report in 2017

12. Current Status Updated Terms of Reference for Forum Next Meeting
Purpose and objectives largely unchanged
Identified issues for new working groups
Open to new members that are able to contribute in a meaningful manner to the working groups
Next Meeting
14-17 November 2017
Combined meeting of steering committee and working groups
