= = = = Isotope and Radioactivity = = =Name of radioactive isotope/electromagnetic radiation/scientist:= CANDU Reactor

= = = = =Explanation of interesting facts: (how used/works.experiments/discoveries)=
 * 1) **CANDU** stands for **CAN**ada **D**euterium **U**ranium
 * 2) It is a power reactor that uses heavy water (deuterium oxide) for moderator and coolant, and natural uranium for fuel.
 * 3) It is the most efficient in all the reactors that uses uranium
 * 4) It is developed by Atomic Energy of Canada Ltd.
 * 5) It was developed in late 1950s and 1960s.

=3 Advantages of using the radioactive isotope/radiation/benefits of discovery=

1.CANDU uses about 15% less uranium than a pressurized water reactor for each megawatt of electricity produced

2.Heavy water used in CANDU reactors is always available. It can be produced locally and re-used.

3.Low fueling cost

=3 Disadvantages of using the radioactive isotope/radiation/discovery:= 1. Heavy water is expensive

2. CANDU reactors could also be used to produce plutonium for nuclear weapons (India & North Korea)

3.Heavy water absorbs few neutrons, and when it does, it produces radioactive tritium. Tritium is a significant radiation hazard. =Is the radioactive isotope/radiation/discovery still used today? Explain.= CANDU reactors are still used in: -Canada -South Korea -India -Argentina -China -Romania -Pakistan
