Types of Nuclear Reactors
They are classified on the basis of:
• Neutron Energy
• Fast Reactors
• Thermal Reactors
• Fuel Used
• Natural Fuels
• Enriched Uranium
• Moderator Used
• Heavy water
• Water Moderated
• Beryllium Moderated
• Graphite Moderated Source: Tsumune et al. (2012)

Pressurized Water Reactor
• The most common nuclear reactor type,
accounting for about 60% of all the nuclear power
reactors globally
• Work by maintaining water under pressure so as
to heat but does not boil
• No mixing occurs between the water from the
reactor and that in the steam generator
• This makes most of the reactivity remain in the
reactor area
• It uses the light water cooled system of cooling
