That low operating temperature also allows the reactor to use natural circulation for cooling instead of energy-hungry pumps.

The LDR-50 aims to solve this problem by providing a more eco-friendly way to heat the water.

The simple design also allows the LDR-50 to come in a cargo container-sized package.

World’s simplest nuclear reactors could be installed underground to provide heat to cities

The company can easily drop in the reactor underground to boost safety while saving coveted urban space.

The company has not explicitly mentioned the nuclear fuel the LDR-50 uses.

The company is backed by Belgian engineering firm Tractebel’s nuclear expertise.
