IAEA Technical Meeting TM-45318

Vienna, 15-17 May, 2013

Scientific Secretary: A. N. Kilic

Purpose of IAEA Technical Meetings

to collect and exchange information on highly specialised

technical matters;

to review specific areas of nuclear science and technology,

to disseminate objective information,

to explore or build consensus on technical issues;

to review specific research and development work;

to provide authoritative advice and input on decision

making;

to enhance interaction among experts from all over the

world in the promotion of the Agency's statutory functions.

Basic Features of IAEA Technical Meetings

• TMs are not open to the public.

• Invitations to attend a TM are sent to select Member States;

requesting designation/participation and/or submission of

scientific contributions;

• The number of participants is restricted to those invited to

participate;

• The working language of a TM is usually English;

• Reports/Minutes from TMs are not published. The

publication of any information resulting from a TM is subject

to the Agency's publication policy.

BACKGROUND TSO Roles and Responsibilities

An effective technical support is essential to operate safely

and to maximize power generation: • ensure that the plant design meets the acceptance criteria for safety,

reliability and quality in accordance with relevant codes and standards, laws

and regulations

• Support plant operations with technical expertise to maintain and improve safe

and efficient performance;

• Identify and resolve any design and performance issue of SSCs and

procedures that support safe and reliable operation which would otherwise

entail cost and unproductive time burdens;

• Make facility (physical and administrative) changes with full knowledge of the

technical basis, intent and philosophy;

• Liaise with the regulatory body in charge of overseeing the facility design and

operation in a controlled and informed manner;

• Understand and update the records of facility information and able to trace it to

the conception of the design.

BACKGROUND IAEA Guidance on TSO Roles and Responsibilities

• IAEA TECDOC-1078 was published in 1999

• In response to recognition that the technical support (TS)

function at some NPPs is sometimes not clearly

understood or adequately addressed, and as the result,

some NPPs have experienced significant performance

problems.

• Targeted NPP management to establish mainly an

effective internal TSO

• Did not address the detailed external TSO interfaces

• Focused on the Operation stage

5

BACKGROUND 2000 - 2012

• New NPPs

• Constructions

• Life Extensions

• Power Uprates

• Heavy Equipment

Replacements

• Additional Operating

Experience

• Decommissions

• Fukushima Accident

Fukushima Technical Impacts

• Regulatory limit, acceptance criteria changes?

• Decrease in the previously proven design safety margin

• Revalidation of original design basis / regulatory & NPP confidence

in margins

• Additional research for justification/confirmation of margin

• New design basis?

• Reclassification and requalification of SSCs?

• SBO equipment

• Requirements for PAM

• SFP cooling/inventory equipment, instrumentation

• Portable/stored equipment

• Requirements for SAM equipment

A TSO is Essential for a Safe and Efficient NPP

• Both for Newcomers and Established NPPs

• For the Entire NPP lifetime (Pre-Design ->

Decommissioning)

• One-time -> Daily Activities (e.g. PUR, Reload, Test)

• Both on-site or off-site activities (Deliverables,

Interfaces)

Technical Support WITH and FOR:

Safety + Quality + Reliability + Efficiency

BACKGROUND – IAEA Activities

• Started in May 2012

• 2 Consultancy Meetings

• 11 Consultants from 7 Member States

• 1 pre-TM Consultancy Meeting

• TM on May 15-17, 2013

• 30 specialists from 17 Member States and

2 International Organizations

• Nuclear Energy Series (NES) Report

11

IAEA - NES (Nuclear Energy Series) Documents

• Provide advice for those either planning or

implementing nuclear activities

• Target audience includes owners and operators of

utilities, implementing organizations, academia and

government officials in Member States, among others

• Based on Best Practices in the MS

• Building on expertise in MS as represented by their

nominees

12

TM-45318 OBJECTIVES

• Share international experience and exchange views on

best practices related to the TS for NPPs, with an

emphasis on new plants;

• Review and discuss IAEA activities including the NES

report in order to jointly contribute to the improvement of

the guidance and support and to enrich the report with

practical examples;

• Strengthen the international networking of specialists

in the TS organization and activities areas.

13

TM-45318 AGENDA

• Presentations from MSs, exchanging information,

as well as providing perspective and suggestions

to IAEA and other MSs

• Panel Session to discuss ideas in a forum format

• Discussion Session to exchange suggestions and

perspectives especially for the Newcomers
