Overview
TNUK strives to invest in the highest quality nuclear industry participants with a strategic advantage due to technology, resource base, asset location, and other factors across the nuclear energy value chain.
Tortoise Capital believes that the global focus on decarbonization and energy security will result in a resurgence in the growth of the nuclear energy sector, and the fund seeks to invest in companies that will benefit from that resurgence.
The TNUK Advantage
Active Differentiation
As an actively managed ETF solely dedicated to nuclear, it allows dynamic allocation across mining, fuel cycles, reactor development, and operators.
Pure-Play Exposure
A tiered methodology emphasizes companies with the highest nuclear revenue and asset exposure, delivering purer access than broad energy or uranium-only ETFs.
Poised for Secular, Long-Term Growth
Positioned at the intersection of rising electricity demand from AI, data centers, electric vehicles, and broader electrification — nuclear energy can be a critical, zero-carbon baseload solution.
Tortoise Platform Strength
Backed by a seasoned energy investment team with a track record of 20+ years managing complex, regulated sectors through multiple market cycles.
Nuclear Renaissance
Nuclear power is regaining importance in the global energy conversation as nations confront the dual challenges of limiting emissions while meeting soaring electricity demand. For years, nuclear power was overshadowed by the rapid rise of renewables and cheap natural gas.
