Is The Heroes of Telemark based on a true story?

Why did Norway have a heavy water plant?
During the German occupation of Norway in World War II, the production of heavy water was judged to be a serious enough threat that at least five separate attacks were launched in order to prevent the Germans from making an atomic bomb.
Who blew up the heavy water plant in Norway during WWII?

Does heavy water ice float or sink?
Ice floats on water because it is less dense, but ice of a special kind can be denser than normal water. Heavy water is indeed heavier than normal water (which contains a tiny amount of heavy water molecules naturally), and heavy-water ice will sink in normal water.
Why do you need heavy water to make a nuclear bomb?
On the eve of World War II, scientists both in Germany and Great Britain realized that heavy water could be used in this way to make nuclear weapons. Heavy water provides a path to turn common uranium into plutonium, one of the easily split or “fissile” materials that fuels nuclear bombs.
Is heavy water drinkable?
While heavy water isn’t radioactive, it’s not entirely safe to drink. Basically, the mass difference slows biochemical reactions that use water. Also, deuterium forms stronger hydrogen bonds than protium, resulting in a different reactivity. You can drink a glass of heavy water and won’t suffer any ill effects.
Where was the Norsk Hydro heavy water plant located?
