Frequently in the press, reporters mention TerraPower’s traveling wave reactor (TWR) alongside many other emerging nuclear reactor technologies. We, of course, want the world to know about our innovations and like to be included in these news reports, but sometimes misperceptions arise. Over time, the popularity of small modular reactor (SMR) designs has caused our design to be lumped into this category. We recognize a unique market for SMRs and applaud efforts to develop this technology. However, TerraPower’s immediate goals require scaling up large-scale electricity access in ways that are affordable, safe and secure for the world’s megacities. So we want to set the record straight.

In summary: our TWR is a big reactor, focused on providing base load power to accommodate the need in parts of the world where electricity demand is growing fastest. We chose this technology and this scale because, according to our analysis, it offers the best commercial solution from many different angles.
