Ordinary light water

Uranium (enriched in U-235), plutonium
name the acid which increases the density of water
Dihydrogen monoxide is the scientific name for water but isn't used a lot
One obscure name for water is H2O, which is the chemical formula for water, one hydrogen molecule and two oxygen molecules. This name is as popular in the mainstream lexicon as it is in scientific circles.
CANDU, a reactor type designed in Canada which uses heavy water as the primary coolant.
India's First Nuclear Reactor was Apsara. It was also the first nuclear reactor in Asia. Apsara went critical at Bhabha Atomic Research Centre (BARC), Trombay on August 4, 1956. It heralded the arrival of India's nuclear energy programme. Dr. Homi Bhabha himself conceptualised the design of the reactor and the reactor was built entirely by Indian engineers in a record time of about 15 months.Apsara is a swimming-pool-type reactor loaded with enriched uranium as fuel. The fuel core is suspended from a movable trolley in a pool filled with water. The pool water serves as coolant, moderator and reflector, besides providing the shielding.
I believe that you fill it with coolant, as the tank's name suggests.

The reactor is roughly cylindrical in shape. Fuel plates or fuel rods are welded up in what is called a fuel bundle, and the bundles are arranged within the inside of the pressure vessel to create the core. There are a number of pictures and drawings that can be viewed by using the links supplied. Note that in the Wwer reactor diagram, part number 1 is said to be the control rods. This is incorrect. What is actually there are the lead screws (and the rod drive motors) for the control rods. The control rods are actually down in the core and are pulled out into the space just above it.
The first Indian nuclear reactor's name is APSARA.
carbonated water is like regular water only pressurized heavily with carbon dioxide. An airtight sealed and pressurized container is needed to keep the carbon dioxide in the water. Once the container is opened, the sorrounding air and tha low pressure forces the CO2 out of the water causing it to bubble.
