Welcome! fromONTARIO POWER GENERATION
Technical Meeting on Integration of Analog and
Digital IC Systems in Hybrid Main Control Rooms

• Rick Hohendorf
• Computers and Control Design

2
Ontario Power Generation

• 12 CANDU power reactors
• Pickering A 4 x 500 MWe
• Pickering B 4 x 500 MWe
• Darlington 4 x 875 MWe
• Designed and put into service over a 25 year
  period
• Different designs/technology vintage

Ontario Power Generation

• One of OPGs stations is performing well with a
  high capacity factor and is moving to a 3-year
  outage cycle
• The other two stations are only part-way through
  their plans for improving their performance

Ontario Power Generation

• Pickering A has been through a life extension for
  2 Units and the remaining 2 Units are out of
  service permanently Safe Store
• On Pickering A, we have replaced the control
  computers that control the reactor
• We also upgraded the main control room operator
  interface 20 years ago and are about to do it
  again

Ontario Power Generation

• Darlington is one of the most highly digital
  plants in operation
• Control computers, both shutdown systems, fuel
  handling computers, common processes computer
• Many other systems contain microprocessor-based
  technology
• More than 1300 PLCs in safety-related and balance
  of plant applications
• Plant information system

6
Ontario Power Generation

• Life extension studies are currently underway for
  both Pickering B and Darlington
• The process for New Build has also been initiated
  for the Darlington site

7
Areas of Current Work

• Day-to-day operations and aging management
  responsibilities for the reactor control
  computers at the 12 Units also control rooms
• S/W Program (including safety critical s/w), HFE
  Program, process control analysis and h/w
  engineering
• Design support for fuel handling s/w, TRF, site
  security systems, and reactor maintenance tools
  (CIGAR)

8
Areas of Current Work

• Currently about 15 projects underway aging
  management of various computer-based plant
  monitoring and control systems and control room
  functions plus the addition of supplementary
  information management systems
• Newly arising issues of cyber security and
  knowledge management
