Deep Fission (FISN) Stock Price, News & Analysis

Company Overview

Deep Fission is a nuclear energy company developing deep-underground small modular reactor technology. Its concept involves placing compact pressurized-water reactors in deep boreholes, with the goal of using the surrounding geology to provide additional protection, containment and security.

The company’s proposed reactors are designed to generate electricity below ground and support applications such as reliable power generation for utilities, industrial facilities and other large energy users. Deep Fission’s technology is intended to address certain land-use, safety and environmental considerations associated with conventional nuclear power plants.

Publicly available information about Deep Fission’s operating history, geographic footprint and leadership is limited. The company remains focused on developing and advancing its underground nuclear power technology rather than operating a broad portfolio of commercial power-generation assets.
