Does Greenpeace support nuclear energy?

Greenpeace got its start protesting nuclear weapons testing back in 1971. We’ve been fighting against nuclear weapons and nuclear power ever since. New nuclear plants are more expensive and take longer to build than renewable energy sources like wind or solar.

Why are we not using thorium reactors?

Thorium cannot in itself power a reactor; unlike natural uranium, it does not contain enough fissile material to initiate a nuclear chain reaction. As a result it must first be bombarded with neutrons to produce the highly radioactive isotope uranium-233 – ‘so these are really U-233 reactors,’ says Karamoskos.

Why dont we use thorium instead of uranium?

Thorium has no isotopes that readily fission to produce energy. So thorium is not usable as a fuel directly, but is instead a fertile nucleus that can be converted to uranium in a reactor. Only after conversion to uranium does thorium become useful as a nuclear fuel.

What is the 90th element?

Today, its radioactivity seems logical as when we look at the periodic table, we find thorium, element 90, just after actinium in the last row of the periodic table known as the actinides, comprising of famous radioactive elements such as uranium and plutonium.

Is nuclear considered green?

In April 2020, the European Commission’s scientific body, the Joint Research Centre, released a report that found that nuclear power is a safe, low-carbon energy source comparable to wind and hydropower in terms of its contribution to climate change.

How much energy does a thorium reactor produce?

The reactor will operate with a power of 300 MWe using thorium-plutonium or thorium-U-233 seed fuel in mixed oxide form. It is heavy water moderated (& light water cooled) and will eventually be capable of self-sustaining U-233 production.

Why is the reactor filled with graphite?

What does graphite do in Advanced Gas-cooled Reactors? The graphite bricks act as a moderator. They reduce the speed of neutrons and allow a nuclear reaction to be sustained.
