Modernization Strategies and their status

• All the Spanish NPPS are in a modernization
  process
• The control rooms will have a Hybrid Human
  Machine Interface
• Without complete modernizations in one outage
• Without strategic alliances with one supplier
  (although main suppliers are preferred)
• The changes start in Non safety (although key
  safety systems are also modernized)
• The simulator is used previously
• Bigger modernization changes
• Vandellós II (Plant computer, Turbine control,
  PLCs, )
• Ascó I y II (Turbine control, Reactor control,
  PLCs, )
• Almaraz I y II (Turbine control, Reactor and BOP
  control in process, )
• Trillo (Teleperm XP installation in YG30, MAE and
  Telecontrol, )
• Garoña (Condensate control, Rod Control, Plant
  computer, Recirculation control, Power Range
  Neutron Monitoring System, )
• Cofrentes (BOP control, Turbine control in
  process, )

12
Modernization Strategie Example Cofrentes (GE)

• Non Safety Honeywell TPS GE Mark VI
• Safety Numac Other (non decided yet)
• Plan for bigger modernizations
• 2009
• Turbine and Bypass Control
• Neutron Monitoring System (PRM)
• Plant Process Computer
• 2011
• Plant Process Computer
• Feedwater Control
• Rod Control Information System
• 2013
• Recirculation Control
• ECCS Controls

IC Licensing in Spain

• Safety Guide 1.11 of the Regulatory body -gt
  Similar to 10CFR 50.59
• Referencia a la USNRC Reg. Guide 1.187, EPRI
  TR-12348 Rev1 NEI 01-01 y al NEI 96-07 rev.1
• A comom guide for IC licensing has been
  developed in the sector
• Regulation of the original country of each NPP
• In the case of an American Plant the main
  regulation is
• 10CFR50 Domestic Licensing of Production and
  Utilization Facilities
• 10CFR50.59 Changes, Tests and Experiments
  Cambiada en año 1999.
• 10CFR50 Appendix A. General Design Criteria for
  NPPS
• 10CFR50 Appendix B. Quality Assurance Criteria
  for NPPS and...
• What about European Guides/Other Guides? Their
  use depends of their consideration in the
  original country of each NPP and the position of
  goups like this

Details of IC Dev. Process

• Tipical engineering Process
• The specification is the Key Phase
• The technical Evaluation is simplified when a
  cualified equipment is used
• In Safety Systems it is needed an independent VV
  
• The Regulatory Body appears from the begining
• The licensing process is completely defined

31
Ideas for the work of the IC IAEA group

• Practical details on normative (classification
  examples in Europe and USA 10CFR50, RSK, IEC
  61226, IEC61508, )
• Practical examples of configuration control in
  real control systems
• Definition of dedication tests
• Summary of Modernizations (finished and in
  process)
• Of bigger systems
• Of smaller systems (mainly 1E)
• Training courses in modernized simulators
• Modernization seminars (like the Nuclear Seminar
  on Nuclear Automation de 2004 organized by NSSK)
• Contacts with other sectors (trains, planes,
  refineries, ...)
