How much concrete goes into building a nuclear reactor

For the same amount of electricity produced, windmills require 50 times more steel and 60 times more concrete than nuclear reactors. This is with the EPR reactor which is a rather "heavy" reactor (more steel and concrete than its' competitors, such as the AP-1000). EFN / Bruno Comby / 7 02 2007

Q&A: Why cement emissions matter for climate change ...

What is cement? Cement is used in construction to bind other materials together. It is mixed with sand, gravel and water to produce concrete, the most widely used construction material in the world.Over 10bn tonnes of concrete are used each year.. The industry standard is a type called Portland cement.This was invented in the early 1800s and named after a building stone widely used in England ...

A Review on Radiation Damage in Concrete for Nuclear ...

Concrete is a relatively cheap material and easy to be cast into variously shaped structures. Its good shielding properties against neutrons and gamma-rays, due to its intrinsic water content and relatively high-density, respectively, make it the most widely used material for radiation shielding also. Concrete is so chosen as biological barrier in nuclear reactors and other nuclear …
