Introduction

There are many reasons why CANDU nuclear generating stations have consistently 
been placed at or near the top of the list of the world's best performing nuclear 
generating stations. This brochure examines one reason for CANDU's success: its 
unique design, a reactor design that has put Canada ahead of all the countries of 
the western world when the achievements of all thermal reactors are considered.

Some of the design features characteristic of the CANDU reactor are:

• a reactor core comprising small diameter fuel channels rather than one huge 
pressure vessel
• separate heavy water moderator and cooling systems
• on-power refuelling
• reactivity devices that are not subjected to high temperatures or pressures
• natural uranium fuel
• reduced consequences from accidental reactivity fluctuations - excess reactivity 
available from the fuel is small and the relatively long lifetime of prompt neutrons 
in the reactor precludes rapid changes in power levels
