The Century Battery: NRD Unveils Nuclear Power Cell with 100-Year Lifespan

GRAND ISLAND, NY – April 10, 2026 – In a move that could redefine the possibilities for remote and autonomous technology, NRD, LLC today announced a solid-state nuclear battery designed to provide continuous power for more than a century. The NBV series power cell, fueled by the radioisotope Nickel-63, promises to eliminate battery replacements for a new generation of ultra-low power electronics operating in the world’s most inaccessible environments.

This technology is not a miniature nuclear reactor. Instead, it harnesses the gentle and predictable process of radioactive decay. The battery is a betavoltaic device, meaning it directly converts the energy from beta particles (electrons) emitted by the decaying Nickel-63 into electrical current. The result is a steady, maintenance-free trickle of power measured in nanowatts, housed in a compact package measuring just 20 by 20 by 12 millimeters.

For industries reliant on data from the edge, this development represents a monumental leap. The prospect of deploying sensors, monitors, or data loggers and having them operate reliably for 100 years could fundamentally alter the economics and capabilities of critical infrastructure, environmental monitoring, and national security.

Redefining 'Long-Lasting' Power

The core of NRD's innovation lies in its use of Nickel-63, a radioisotope with a half-life of approximately 100 years. As the isotope decays, it emits low-energy beta particles but no significant gamma radiation, a key safety feature. These particles are captured by a semiconductor junction within the battery's solid-state architecture, generating a continuous flow of electricity. The entire process is sealed, silent, and produces no heat or moving parts.

“Simply stated, critical mission sets collapse if a component, such as a battery, within the power matrix is compromised or fails,” said Shel Alfiero, NRD's Chief Executive Officer, in the company's announcement. “NRD's NBV series is a high-integrity, maintenance-free micro power solution for applications that demand protracted reliability and consistent power in exacting and hostile environments, where battery replacement is not a realistic option.”

While the power output is modest—ranging from 5 to 500 nanowatts—it is perfectly suited for the growing field of ultra-low power electronics. This includes applications like 'keep-alive' functions for AI systems to retain memory, unattended sensors that wake up periodically to transmit data, and long-duration health monitors where minimal maintenance is paramount.

The company is leveraging its deep institutional knowledge to bring this product to market. “This launch is a milestone as NRD translates decades of regulated nuclear materials expertise into next-generation power solutions,” noted Kevin Heffler, Chief Operations Officer. He highlighted NRD's six in-house radiological laboratories and mature radiation safety program as foundational to scaling production.

Unlocking the Unreachable

The true impact of a century-long power source is best understood through its potential applications. Imagine environmental sensors dropped into the Arctic to monitor climate change for generations, not just seasons. Consider smart infrastructure where sensors embedded deep within concrete bridges or dams report on structural integrity for the entire lifespan of the structure itself. In aerospace, such batteries could power deep-space probes or provide decades of reliable power for critical satellite subsystems.

While the upfront cost of such specialized technology is expected to be significant—similar betavoltaic devices from competitors are priced upwards of $5,000 per unit—the value proposition is rooted in the total cost of ownership. For a device located on the seabed, on a remote mountaintop, or inside a critical piece of industrial machinery, the cost of a single battery replacement mission, including labor and logistics, can dwarf the initial component cost. By eliminating maintenance entirely, the NBV series aims to make previously cost-prohibitive or logistically impossible projects viable.

An Emerging Field of Micro-Nuclear Energy

NRD is not alone in the race to commercialize nuclear micro-power. The announcement places the Grand Island-based manufacturer in a dynamic and competitive emerging market. Earlier in 2024, Chinese startup Betavolt made headlines with its own Nickel-63 battery, claiming a 50-year lifespan and a higher power output of 100 microwatts. In the United States, Miami-based City Labs has been producing its NanoTritium™ batteries for years, which use the isotope Tritium to offer a 20-plus-year lifespan, securing contracts with NASA and the Department of Defense.

Each technology has its trade-offs. Tritium has a shorter half-life of 12.3 years, leading to a shorter operational life for the battery compared to Nickel-63. NRD's focus on a 100-year horizon appears to be a direct strategy to capture the market for applications where extreme longevity is the single most critical factor. This burgeoning field underscores a global trend towards developing persistent, autonomous power sources that untether critical electronics from the grid and the limitations of conventional chemical batteries.

Balancing Innovation with Responsibility

The word “nuclear” inevitably raises questions of safety and environmental impact. However, betavoltaic technology operates on principles vastly different from nuclear power plants. The low-energy beta particles emitted by Nickel-63 cannot penetrate human skin and are fully contained within the battery's sealed, solid-state casing. Over its 100-year half-life, the Nickel-63 slowly transforms into stable, non-radioactive copper, a benign and common metal.

The manufacture, transport, and disposal of these devices are strictly regulated by bodies like the U.S. Nuclear Regulatory Commission (NRC) and the Environmental Protection Agency (EPA). NRD's history, which includes producing over 750 million Americium-based smoke detectors, demonstrates extensive experience navigating this complex regulatory landscape.

At the end of its exceptionally long life, the battery will be treated as low-level radioactive waste (LLW), requiring disposal at a licensed facility. This is a standard and well-understood process for a wide range of materials used in industrial and medical fields. By providing a clear path for responsible end-of-life management, companies like NRD aim to build the public trust necessary to deploy these innovative technologies safely and effectively, ensuring that the power to operate for a century comes with the foresight to manage it for even longer.
