Building Nuclear Micropower Systems for Mission-Critical Environments

City Labs develops tritium-powered systems for space, defense, medical, and industrial applications that require long-duration power, heat, and autonomous operation.

With specialized tritium infrastructure, in-house manufacturing capabilities, and regulatory experience, City Labs is advancing nuclear micropower technologies built for deployment.

RMC Building City Labs

Company Overview

City Labs has spent more than two decades developing long-duration tritium-powered technologies.

City Labs develops a broad nuclear micropower ecosystem that includes electrical power, thermal systems, hybrid thermal-electric architectures, and propulsion concepts built around tritium and tritium metal hydride technologies. City Labs is focused on systems that must operate for years in places where conventional batteries, solar power, and routine maintenance are not practical.

Specialized Tritium Infrastructure

City Labs operates specialized infrastructure for the development and production of tritium-based systems. This infrastructure is central to the company’s ability to move from material development to functional hardware within an integrated operating environment.

Capabilities include:

  • Tritium processing
  • Metal hydride loading
  • Thin-film deposition
  • Device assembly
  • Hermetic sealing
  • Leak testing
  • Electrical characterization
  • Thermal and environmental testing
  • System integration and packaging

Vertical Integration

City Labs’ platform is built around the ability to control critical steps in the development of tritium-powered systems, from tritium handling and metal tritide formation to packaging, testing, qualification, and regulatory documentation.

This integrated approach helps City Labs translate customer requirements into deployable hardware for mission-critical applications.
