The thinking is that you could bury a small reactor in a shallow layer of bedrock, perhaps 30-50 meters underground. Then, if things at the plant go south for any reason, the granite will provide natural containment; simply cement in any access tunnels going down to the facility and walk away.
The idea was first floated last fall by Hooman Peimani an energy security specialist at the National University of Singapore. Countries with nuclear power typically build large-scale reactors 15 to 20 km away from heavily populated residential areas. Singapore, a country of roughly 700 square kilometers, doesn't have a potential site even 3 km from residential areas, Peimani says.
Going underground would significantly increase the costs of any reactor. Peimani says only small reactors 30-50 megawatts in size, one-twentieth the size of conventional large-scale reactors, would be cost effective.
peimani is er mee bezig dus. misschien wordt het wat.
