What are the different types of nuclear reactor?
Main types of nuclear reactor
- Pressurised water reactor (PWR)
- Boiling water reactor (BWR)
- Advanced gas-cooled reactor (AGR)
- Light water graphite-moderated reactor (LWGR)
- Fast neutron reactor (FNR)
- Operable nuclear power plants.
How many types of boiling water reactor cycles are there?
See the section below to view a basic operating cycle of a boiling water power plant. Figure 2….Boiling water reactor.
| Type | Number of Reactors |
|---|---|
| PWR | 297 |
| BWR (Boiling Light-Water Cooled and Moderated Reactor) | 75 |
| PHWR (Pressurized Heavy-Water Moderated and Cooled Reactor) | 49 |
Which of the following reactor types used heavy water as a coolant?
pressurized heavy-water reactor
A pressurized heavy-water reactor (PHWR) is a nuclear reactor that uses heavy water (deuterium oxide D2O) as its coolant and neutron moderator.
What is borated water?
Borated water is used as a coolant during normal operation of pressurized water reactors (PWRs) as well as in Emergency Core Cooling Systems (ECCS) of both PWRs and boiling water reactors (BWRs).
Which is better BWR or PWR?
Another advantage is that the PWR can operate at higher pressure and temperature, about 160 atmospheres and about 315 C. This provides a higher Carnot efficiency than the BWR, but the reactor is more complicated and more costly to construct. Most of the U.S. reactors are pressurized water reactors.
What is BWR and Phwr?
A Boiling Water Reactor (BWR) A Pressurized Heavy Water Reactor. (PHWR/Candu) An Advanced Gas-cooled Reactor (AGR) A Light Water Graphite-moderated Reactor.
Which is safer BWR or PWR?
Since the working fluid loop is separated from the primary loop, so PWR is less risky in spreading of radioactive materials owing to leakage. Since same fluid passes through the reactor and turbine in BWR plants, so any leakage in the turbine can spread radioactive elements into the atmosphere.
What is Candu type reactor?
What is CANDU. CANDU ® stands for “CANada Deuterium Uranium”. It’s a Canadian-designed power reactor of PHWR type (Pressurized Heavy Water Reactor) that uses heavy water (deuterium oxide) for moderator and coolant, and natural uranium for fuel.
What is GLR reactor?
Glass lined Reactors (GLR’s) have a glass (enamel) coating on the product wetted surfaces to provide high levels of chemical resistance to said surfaces.
