  electrical energy, 50 trade
• ISO/IEC agreement
• WTO, TBT agreement recognising ISO/IEC standards
• IEC/IAEA collaboration
• IEC/CENELEC
• IEC/IEEE collaboration

What did not change since May 2005 Organization
(2/2)

• 7 Working Groups
• WG A2 Instruments and Sensors, Mr. Burel
  (France)
• WG A3 Application of digital processors to
  safety in NPP, Mr. Lindner (Germany)

5
What did not change since May 2005 IEC/SC45A-IAEA
relationships

• 1981 IEC/TC45 IAEA agreement to eliminate the
  overlap between the 2 bodies
• IAEA responsible for developing safety
  principles, Withdrawal of the IEC/SC45A 231
  series tackling principles for safety IC in the
  70s
• IEC/SC45A develop standards compliant with IAEA
  safety principles (for example IEC 60880 on
  safety software compliant with NS-G 1.1 and NS-G
  1.3)
• IEC/SC45A terminology aligned on IAEA terminology
• Systematic exchanges of significant documents for
  comments assure consistency
• Invitation of the representatives of the IAEA to
  the IEC/SC45A meetings

6
Whats new - Going more global

• 21 countries participating voting in the SC45A
  activities Argentina joined
• Argentina, Belgium, Canada, P.R. of China, Czech
  Republic, Egypt, Finland, France, Germany, Italy,
  Japan, Norway, Rep. of Korea, Romania, Russian
  Federation, South Africa, Sweden, Switzerland,
  United States, Ukraine, United Kingdom
• Decision of revision of IEC 60780 (Qualification
  of electrical systems) in parallel and
  collaboration with IEEE/NPEC
• Enforcement of a SC45A terminology policy to
  guarantee full consistency between IAEA and SC45A
  documents

7
Whats new Going more global - Developing
collaboration with CENELEC

• WENRA, First level of harmonization for nuclear
  regulatory systems to be reached in Europe in
  2010
• CLC/BTTF127-1, 2006-2007, European WG to prepare
  the decision of publishing European standards for
  NPP IC, endorsing IEC/SC45A standards
• Decision to be taken by CENELEC BT in September
  2007

8
Whats new A (complemented) up to date,
consistent, comprehensive standard series on
computer based systems important to safety

• IEC 61513 General requirements, 2001 (in
  revision)
• IEC 61226 Classification of IC functions, 2005
• IEC 60671, Surveillance testing, 2007
• IEC 60709 Separation, 2005,
• IEC 60880 SW of CB systems performing A
  functions, end 2005
• IEC 60987 HW of CB systems performing A, B and C
  functions, 2007
• IEC 62138 SW of CB systems performing B and C
  functions, 2004
• IEC 62340, Common Cause Failure, 2007

9
Whats new IEC 60880, May 2006

• Revision of the original 1986 version, referenced
  in many contracts, used by SA as reference in
  many countries
• Takes into account the recent advances of
  software engineering techniques
• Integrates of the IEC 60880 part 2 published in
  2000
• Aligned with IAEA documents NS-R-1 (Design) and
  NS-G-1.3 (IC)
• Consistent with IEC 61513, IEC 61226, IEC 60709,
  IEC 60671, IEC 60987, IEC 62138, IEC 62340

10
Whats new Other publications

• IEC 60515 Radiation detectors
• IEC 60568 In core instrumentation for neutron
  fluence rate measurements
• IEC 61225 Requirement for electrical supplies,
  2005
• IEC 62397 RTDs (Resistance Temperature Detectors)

11
For the coming years Why to join IEC/SC45A ?

• IEC/SC45A standards are equipment specific based
  on IAEA safety principles
• IEC/SC45A standards are consensus based (1 stage
  for comments, then 1 stage for comments and
  voting and then 1 stage for final voting)
• IEC/SC45A standards are used in various countries
  for procurements but also by regulatory organisms

12
For the coming years IEC SC45A strategy

• To increase the participation of NPP generating
  countries all over the world (Asia, South
  America, Eastern Europe)
• Address the complete nuclear cycle
• Take into account the safety/security needs
• Liaise with all the major standardization bodies
  (IAEA, IEEE, CENELEC).
