Swiss Utilities – New Nuclear Power Plant Projects



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

Conditional approval for all 3 sites published by SFOE in Nov. 2010

Fukushima



Consequences of Fukushima Daiichi accident (1)

Procedures for pending General Licence Applications suspended by Federal Council in March

ENSI issued 3 directives to NPPs to proof their design for - 10‘000 years earthquake- 10‘000 years flooding- Combination of earthquake and flooding

ENSI required a central storage for SAMG equipment which has to be- earthquake and flood proof- accessible by helicopter stationed in Switzerland- equipment has to be transportable by helicopter (if accessibility of plants in

emergency is not given) Additionally ENSI issued a further directive to investigate spent fuel

pool cooling (individual for each site)



Consequences of Fukushima Daiichi accident (2)

Before Fukushima rather pro-nuclear public opinion skips to anti-nuclear (amplified by the media)

May 22nd „people current against atom“ organized by anti nuclear organizations in the NPP Beznau vicinity

- About 20‘000 participants- Peaceful event

May 25th the federal council (Bundesrat) decides on nuclear future- Different scenarios will be considered (fast, slow or no phase out)

June 8th the parliament (Nationalrat) discusses on nuclear future

Outcome open, if „pro nuclear“

Referendum against new nuclear plants almost sure!!



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



Swiss Recommendations (2)

Modernisation of I&C Systems and Components- I&C Modernization Strategies for Plant-Wide Simplification and Cost Reduction

I&C HW and SW Life-Cycle Related Issues- Configuration management guidelines for digital I&C systems- Dealing with short lifecycle of digital components

Human Factors and Reliability, Main Control Room (MCR) Design, Human System Interface (HSI)

- Upgrading existing control rooms: opportunities and limitations



I thank you for your kind attention!
