How does an EPR reactor work?
How does an EPR reactor work?
A pressuriser connected to one of the coolant loops is used to control the pressure in the primary circuit. Feedwater entering the secondary side of the steam generators absorbs the heat transferred from the primary side and evaporates to produce saturated steam.
What is EPR technology?
The EPR is a third generation pressurised water reactor design. It has been designed and developed mainly by Framatome (part of Areva between 2001 and 2017) and Électricité de France (EDF) in France, and Siemens in Germany.
How many fuel assemblies are there in EPR?
241 fuel assemblies
The U.S. EPR fuel system consists of a reactor core containing 241 fuel assemblies and 89 control rods, or rod cluster control assemblies. Each fuel assembly is made up of 265 fuel rods and 24 guide tubes arranged in a 17×17 array.
What type of reactor is HPC?
Hinkley Point C nuclear power station
|Hinkley Point C nuclear power station (HPC)|
|Employees||6300 On-site construction workers|
|Nuclear power station|
Why is PWR better than BWR?
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.
Are EPR reactors safe?
The EPR has been designed to have a service life of 60 years, compared to 40 years for existing plants. An even higher level of safety Safety in the nuclear industry is an integral part of continuous progress. Pressurized water reactors, such as the EPR, are extremely safe industrial facilities.
What are EPR projects?
Project management / Design Nuclear France The EPR (European Pressurized Reactor) is a new generation of pressurized water reactors, producing 1600 MW. It complies with the latest international safety standards and ensures competitively-priced and greenhouse gas-free production of electricity.
What type of reactor is Hinkley C?
EPRs – originally known as European Pressurised Water Reactors – are a type of Pressurised Water Reactor (PWR). The design of the UK EPRs that will be built at Hinkley Point C represents a major development on previous PWRs, making them amongst the safest and most efficient civil nuclear power generators ever designed.
How much energy will HPC produce?
The reactor at Hinkley Point C Hinkley Point C will be the first in a new generation of nuclear power stations in the UK. The planned twin unit UK EPR is capable of generating 3,260MW of secure, low carbon electricity for 60 years.
What is the difference between PWR and PHWR?
In PWR, normal water or light water (H2O) is used as coolant-cum-moderator. In PHWR, heavy water (D2O) based on deuterium is used as coolant, and also as moderator (but they are not allowed to mix). Enriched uranium with around 3 – 5% U-235 isotope is used as fuel in the PWR reactors.
What are PWRs and BWRs?
Pressurized water reactors (PWRs) and boiling water reactors (BWRs) are classified as light water reactors (LWRs). In the United States LWRs are used in the production of electric power. As of 2016, 69 out of 104 commercial nuclear power plants licensed by the U.S Nuclear Regulatory Commission are PWR’s. [ 1,2]
