Inside the town that's Russia's top target

Hello. Pokrovrsk - once home to 69,000 residents - might not be well-known beyond Ukraine's borders but it has huge strategic importance. Abdujalil Abdurasulov describes the mood as the invading Russians approach. As nuclear-powered countries wrestle with the problem of dealing with radioactive waste, our science reporters examine the UK's plans. And BBC Panorama's Oana Marocico and Ben Milne hear claims about controversial influencer Andrew Tate.

Addressing the nuclear waste puzzle

Sellafield in England's north-west is the temporary home to the vast majority of the UK's radioactive nuclear waste, as well as the world's largest stockpile of plutonium. A complicated search - both scientifically and politically - is on for somewhere to lock it away from humanity permanently.

What is nuclear waste?

Nuclear power comes from radioactive uranium atoms, which are split in a reactor to produce heat. This heat generates electricity that can be used to power homes, school, businesses, hospitals, etc. Leftover radioactive waste is cooled and stored, and contains harmful radiation. It releases energy that can penetrate and damage the cells in our bodies, and "it remains hazardous for 100,000 years", explains Claire Corkhill, of the University of Bristol.

So, what's the latest plan to store it?

"We turn it into a solid - glass, ceramic or a material that’s just like the rocks that the uranium originally came from," explains Prof Corkhill. The plan for permanent, underground storage is to contain that solid waste in a Russian doll-like series of barriers. The glass, encased in steel, will be shielded in concrete, then buried beneath the Earth's own barriers - layers of solid rock.

Is anything similar being done elsewhere?

In Finland, a facility called Onkalo has already been built and could receive its first nuclear waste within the next year. Locations for three other sites around the world have also been chosen, in Switzerland, Sweden and France. They are at various stages of development.

THE BIG PICTURE

'Tate raped and strangled us' - claims

Influencers Andrew and Tristan Tate already deny claims in Romania of human trafficking and forming an organised group to sexually exploit women. Now, two British women not involved with that case have given detailed first-hand accounts of alleged rape and sexual violence by Andrew Tate. The claims date back at least 10 years, to when he was living in England.

And finally... in Scotland

The BBC has met Gemma Doherty, a 41-year-old woman who has taken up stone lifting as a hobby. Stone lifting is, you guessed it, the competitive lifting of heavy stones. The mum of two says she hopes that it inspires her two daughters to believe that they can do anything. If I'm honest, if that anything involves lifting rocks as big as these, I'm pretty sure I couldn't.
