  17. Swiss Utilities – New Nuclear Power Plant Projects • General Licence Applications for 3 new NPP‘s submitted to the SFOE • RESUN AG (Axpo / BKW) in December 2008: • at NPP Beznau and NPP Mühleberg site • KKN AG (Alpiq) in June 2008: • at NPP Gösgen site

  18. Swiss Recommendations (1) • Design, Qualification, and Application of Digital I&C Systems • Investigating the best practices for the diversity and defence-in-depth analyses performed for digital I&C systems and determining what constitutes an adequate diversity and defence-in-depth • Selection and justification for level of diversity • Qualification of digital equipment and its programming. Type test of platforms. Requirements for safety application. Does object oriented programming provide the required reliability? • Hardware & Software Qualification Method for ASIC/CPLD/FPGA • TECDOC to establish engineering rules for plant computer system connecting to outsiders with respect to security • Qualification of I&C components. Harmonisation of qualification and type test of LOCA as well as non-LOCA, seismic and non-seismic, etc. qualified equipment

  20. Swiss Federal Nuclear Safety Inspectorate ENSI Part 1: Transfer from HSK to ENSI = Independence of the swiss regulatory authority

  21. Initial situation before transfer HSK to ENSI (not independent from SFOE) Reporting structure • The HSK is the regulatory authority of the Swiss Confederation with responsibility for nuclear safety • Administratively, it currently reports to the SFOE (Swiss Federal Office of Energy) • SFOE is responsible, therefore, for both the use of nuclear energy and protection from it Independence • Potential conflicts of interest require the institutional separation of use and protection functions • Formal separation is called for in both the international Convention on Nuclear Safety and the Swiss Nuclear Energy Act

  22. Principal aspects of ENSI Act on the Swiss Federal Nuclear Safety Inspectorate • Final approval on 22.06.07 by the Parliament Legal structure • Institution of public law with its own legal personality • Functionally, institutionally and financially independent Supervision • Supervised by federal council • ENSI reports annually about activity and finances Duties • Supervisory authority for nuclear safety (as hitherto) • Supervisory authority for physical protection (new)

  23. UVEK BFE SK HSK Situation in 2007 • Government • Energy policy • Strategic and safety objectives, budget • Grants General License • Advisory body • Comments on applications • Observation of operation • Advise on fundamental questions Federal Council KSA • Department • Grants construction and operation license • Office of Energy • Implementation of energy policy • Preparation of legislation, • Lead in procedures • Supervision of Physical Protection • HSK • Supervision of nuclear safety and radiological protection of NPPs

  24. Situation in 2009 • Government • Energy policy • Grants general license • Advisory body • Comments on applications • (second opinion) • Advise on fundamental questions Federal Council Auditing Agency - Financial audits Auditing Agency KNS • Department • Grants construction and • operation license • Office of Energy • Implementation of energy policy • Preparation of legislation, • Lead in procedures • ENSI Board • Strategic & safety objectives, • Budget • ENSI • Supervision of nuclear safety • and radiological protection • Supervision of physical • protection ENSI Board UVEK ENSI(HSK+SK) BFE

  25. Swiss Federal Nuclear Safety Inspectorate ENSI Part 2: New Guidelines based on new act and ordinance

  26. Swiss Federal Nuclear Safety Inspectorate ENSI Structure: act (SR732.1) ordinance (SR732.11) guidelines Category: G A B general plant monitoring of assessment operation

  27. Swiss Federal Nuclear Safety Inspectorate ENSI Examples for category G guidelines: • G01 Safety classification for light water reactors e.g. SK1, 1E, EK1 • G02 Design principles for light water reactors • G03 Requirements for deep geological repositories • G05 Transport and temporary storage casks • G08 Requirements for systematic safety assessment • G09 Requirements for operating documentation

  28. Swiss Federal Nuclear Safety Inspectorate ENSI Examples for category A guidelines: • A01 Design accident analysis (methods and boundary conditions) • A02 Application for approval of construction and operation licence • A04 Application for approval for a modification in a nuclear installation • A05 Probabilistic Safety Analysis (quality and scope) • A06 Probabilistic Safety Analysis (applications) • A08 Requirements for calculation of source terms

  29. Swiss Federal Nuclear Safety Inspectorate ENSI Examples for category B guidelines : • B01 Methods and scope for ageing surveillance • B02 Periodical reporting (monthly, yearly, yearly shutdown, etc.) • B03 Notification from nuclear installations • B11 Emergency exercise • B14 Requirements for maintenance of I&C and electrical equipment
