OPEN100 is informed by a deep dive into the triumphs and failures of the nuclear industry, incorporating the best elements of design, engineering, and execution, while learning from historical setbacks and misaligned incentives. The nuclear industry must innovate, but in the service of making nuclear power cheaper rather than reinforcing outmoded designs and regulations. Only then can nuclear be a viable technology, enabling the transition to a carbon-free world.

What makes OPEN100 innovative?

The OPEN100 design is based on a standard Pressurized Water Reactor (PWR), the workhorse of the industry with 300 units in operation around the world. Our innovation is an implementation and deployment platform—there are no changes to the nuclear technology itself. While there are many exciting technological developments to reactor core design slated to emerge in the coming decades, we made a deliberate choice to avoid new reactor technologies to streamline licensing, utilize the standard supply chain, and eliminate technology risk.

How is this different from a standard PWR?

Three main assumptions have driven our design:

  • Operated by digital controls that are common throughout the energy industry,

  • Sized to 100MW electric to match standard power plant equipment,

  • Licensed through a modernized, performanced based, regulatory process utilizing probabilistic risk analysis.

Why open source?

Why 100MW?

Who can contribute?

What are the potential applications?

Is nuclear energy "clean"?

Is there a limited supply of nuclear fuel?

Can nuclear power plants produce nuclear weapons?

Will nuclear power plants always be slow and expensive to build?
