|
|
|
pressurised water is pumped into the core.
|
|
|
coolant water is allowed to boil in the core of the reactor.
|
|
|
fuel and the coolant are thoroughly mixed to form a homogeneous solution.
|
|
|
coolant water, after being heated in the reactor core, generates steam in a boiler.

Detailed explanation-1: -The BWR uses ordinary water (light water) as both its coolant and its moderator. In the BWR the water in the reactor core is permitted to boil under a pressure of 75 atmospheres, raising the boiling point to 285°C and the steam generated is used directly to drive a steam turbine.
Detailed explanation-2: -As mentioned before, light water is used as the coolant and moderator for a boiling water reactor. Light water is much more abundant than heavy water, as it makes up 99.99% of natural water. The use of light water as a coolant is beneficial as it can cool down the fuel at the same time as it heats up to steam.
Detailed explanation-3: -So, the coolant used in a boiling water reactor is a mixture of water and steam.
Detailed explanation-4: -The correct answer is Nuclear Reactor. Two of the most common reactors are Pressurized Water Reactors and Boiling Water Reactors, both of which are light water reactors (LWR).
