The TerraPower design, which it calls Natrium and has been developed jointly with GE Hitachi, has several novel features. Probably the most notable of these is the use of liquid sodium for cooling and heat transfer. This allows the primary coolant to remain liquid, avoiding any of the challenges posed by the high-pressure steam used in water-cooled reactors. But it carries the risk that sodium is highly reactive when exposed to air or water. Natrium is also a fast-neutron reactor, which could allow it to consume some isotopes that would otherwise end up as radioactive waste in more traditional reactor designs.

There are a few other Pixel phones worth considering if you don't want any of the above choices. The Pixel 8 and Pixel 8 Pro are available through official channels and third-party retailers (until supplies last). The key is to not pay more than $500 or $600 for either of them; otherwise, you may as well put that money toward the Pixel 9 or Pixel 10 series.
