Power Plant Computer Systems | CANDU Plant Computer Systems (DCCs)

The first CANDU* reactor (Pickering A, Unit 1), began commercial operation in 1971 at Ontario Hydro's Pickering A reactor site, just east of Toronto. In 1973, the Pickering A Nuclear Generating Station equipped with four CANDU reactors, produced more electricity than any nuclear power station in the world at that time.

Through cooperation with CANDU designer Atomic Energy of Canada Ltd. (AECL) and/or Candu Energy, or directly with power generation utilities, L3 MAPPS has been supplying CANDU plant computer systems - known as Digital Control Computer (DCC) systems - for nuclear power plants since 1970. DCC systems are used to monitor and control all the major reactor and power plant functions. In response to demand, L3 MAPPS has continued to upgrade the technology over the last three decades.

L3 MAPPS has sold DCC systems for CANDU nuclear power plants in Argentina, Canada, China, Italy, Korea and Romania. Since 2006, L3 MAPPS has been working with the CANDU Owners Group (COG) to enhance the DCC technology and documentation to serve as a reference for future DCC projects. A current generation DCC system resides at L3 MAPPS' main Montreal, Canada facility and is used to provide support to all participating COG members for up to 30 years.
