CNSC to start design compliance review of Enhanced CANDU 6 nuclear reactor



    Service agreement between AECL and CNSC signed

    MISSISSAUGA, ON, May 12 /CNW/ - Atomic Energy of Canada Limited (AECL)
and the Canadian Nuclear Safety Commission (CNSC) have signed a service
agreement to review the Enhanced CANDU 6(TM) (EC6(TM)) nuclear reactor. Under
the service agreement, the CNSC will conduct a high-level review of the EC6
design based on the Regulator's expectations set out in Regulatory Document
RD-337 for new nuclear power plants in Canada.
    "We are very pleased that the CNSC has agreed to review our EC6 design,"
says AECL President and CEO Hugh MacDiarmid. "The EC6 can serve the energy
needs of a distinct market where customers are looking for an efficient
nuclear solution that offers natural uranium fuel efficiency, proven
reliability and a size to match grid requirements."
    The EC6 is a Generation III 740 MWe pressure tube reactor, designed to
meet current robust international industry standards and public expectations
for safe, reliable, environmentally friendly, nuclear power generation. The
EC6 design is enhanced by the experience and feedback AECL has gained in the
design, construction and operation of the 11 CANDU 6 plants operating in five
countries worldwide.
    "We welcome the start of this review as activity to build new nuclear
reactor plants continues to surge around the world, " says MacDiarmid, "and
the world is interested in the full suite of CANDU(R) designs - the Advanced
CANDU Reactor(R) (ACR-1000(R)), the CANDU 6, and the EC6 -all of which will
strengthen Canada's tremendous opportunity to benefit from international and
domestic nuclear reactor sales."
    The EC6 reactor has a projected annual performance factor of over 90%.
This is based on the proven reliability of the global CANDU 6 fleet that has
an average lifetime performance factor of 89%, ranking it as one of the
world's top performing nuclear power reactors.
    The CNSC is expected to complete the high-level compliance review by
February 2010.

    About the EC6

    The Enhanced CANDU 6 (EC6) is a heavy water-cooled, heavy
water-moderated, natural-uranium fuelled pressure tube reactor retaining the
proven features of the CANDU 6 design while incorporating design and safety
improvements to ensure that the safety, operation and performance of the
Enhanced CANDU 6 meet modern international standards.

    
    EC6 Enhancements:

      -  Increased safety and operating margins
      -  Enhanced accident resistance and core damage prevention
      -  Added containment protective features designed to withstand external
         events such as an airplane crash
      -  Improved fire protection
      -  Greater resistance to earthquakes
