Busting myths about nuclear energy

There's lots of talk about nuclear energy, but what's true and what's not? Let's bust some myths!

Myth 1: Nuclear energy is unsafe

Fact: Safety is at the heart of everything we do at EDF Energy power stations. In our 42 year operating history, there has never been an incident involving release of radiation offsite from any of our UK nuclear power stations. Nuclear power is one of the most highly regulated industries in the UK. 

Myth 1: Nuclear energy is not safe

Fact: Safety is at the heart of everything we do at EDF. We've been operating safely in the UK for more than six decades out of our 8 power stations. Nuclear power is one of the most highly regulated industries in the UK. 

Myth 2: Nuclear energy contributes to carbon emissions

Fact: Nuclear is a low-carbon energy source. It’s got one of the smallest carbon footprints. HPC will save 9 million tonnes of CO2 per year – equal to taking 4 million cars off the road each year.

Myth 3: We don't need nuclear power in the UK

In the UK right now there's a huge and ongoing demand for electricity. And in fact, alongside wind and solar, nuclear is part of the solution – being able to power our homes with low-carbon electricity. 

Where wind and solar energy rely on the weather, nuclear is always able to provide power. Nuclear is an important part of the UK’s low-carbon energy mix – something we can’t simply ‘turn off’.

Myth 4: Nuclear waste needs to be stored forever!

Fact: Most nuclear fuel can be recycled to create new fuel or byproducts. A small amount of nuclear waste does need to be stored, but for less than 300 years (not thousands).

Over 90% of the waste produced from nuclear power stations is classified as low or intermediate-level waste. That includes things like scrap metal, paper, plastics and clothing, and most of it can be processed at a repository in Cumbria. 

A small amount of nuclear waste is classed as high-level waste and does need to be stored long-term. The main hazard with high-level waste is radioactivity, although this diminishes with time.

The nuclear industry has developed many technologies to deal with the waste produced. At the moment, nuclear waste is stored above ground. These stores on the surface can be kept safe for decades. Ultimately, the UK Government is establishing a Geological Disposal Facility (GDF) to provide a permanent solution for this type of waste.

Geological disposal is when nuclear waste is placed into special containers, which are then placed in tunnels and vaults under many hundreds of meters of solid rock.

EDF will store all the nuclear waste and spent fuel produced by new power stations onsite during their 60 year operational period. The site will then go into a programme of decommissioning and the waste transferred for long term storage. Decommissioning involves shutting down the power station safely so it no longer needs radiation protection measures.

 

 

Myth 5: Exposure to radiation only occurs from a nuclear power station

Did you know that radiation occurs naturally in foods such as Brazil nuts, bananas and coffee?

We might not know it, but we're all exposed to background radiation as part of our everyday lives. It's all around us and occurs naturally, as well as being produced artificially.

Radiation from the nuclear industry is actually much lower than what occurs naturally.
