Waste Disposal Fund for Nuclear Power Plants
The Waste Disposal Fund for Nuclear Power Plants was created in 2000 as Switzerland's statutory financing vehicle for nuclear waste management. Based in Bern and managed by STENFO, the fund collects mandatory annual contributions from Switzerland's nuclear power plant operators. Its sole purpose is ensuring that the eventual costs of radioactive waste disposal and plant decommissioning are fully covered, insulating taxpayers from a liability that stretches across generations. The fund's strategy is defined by an ultra-long investment horizon matched to the delayed cash outflows of nuclear cleanup. Asset allocation spans green bonds, a global fixed-income mandate, and a pan-European commercial real estate portfolio. The green bond book reflects a thematic alignment with environmental objectives that mirrors the fund's foundational mission. Real estate holdings are concentrated in commercial properties across Europe. The fund operates under investment guidelines established by its supervisory authority, the German Federal Ministry of Finance, and benefits from structural guidance provided during its inception by Sweden's AP4, a pension fund with comparable liability-driven investing experience. STENFO executed the investment activity through a dedicated investment commission. In 2020, the fund became the first sovereign-backed entity of its kind to join the UN-convened Net-Zero Asset Owner Alliance, signaling a posture that integrates long-term climate risk into a portfolio where the underlying liability is measured in millennia. The fund is also a signatory to the Principles for Responsible Investment and a member of INREV, the European association for investors in non-listed real estate vehicles. These affiliations provide operational frameworks for governance and reporting rather than serving as capital-raising networks. The fund's structural differentiator is temporal. No private-sector asset owner operates with a liability tail that literally extends beyond the design life of current geological repositories. That singularity forces a portfolio construction philosophy in which liquidity is secondary to solvency, and the discount rate applied to future obligations is a governance question as much as an actuarial one. The board includes Udo Philipp, State Secretary at Germany's Federal Ministry for Economic Affairs and Climate Action, anchoring the fund's oversight within cross-border regulatory architecture rather than purely Swiss federal supervision.

Frequently asked questions
Who runs investment decisions at the Waste Disposal Fund for Nuclear Power Plants?
Anja Mikus serves as both Chief Executive Officer and Chief Investment Officer, consolidating executive and portfolio-construction authority in a single role. The investment activity is overseen by an investment commission managed by STENFO. Dr. Thomas Bley functions as CFO and Chief Risk Officer, while Verena Kempe heads Investment Management, forming the core investment-operations leadership group.
Where does the fund's capital come from?
Capital originates from mandatory annual contributions paid by Switzerland's nuclear power plant operators under federal law. These contributions are statutory obligations, not voluntary corporate allocations. The fund is managed by STENFO and supervised by the German Federal Ministry of Finance, which sets the investment guidelines governing how the accumulated capital is deployed.
How is the fund's investment strategy shaped by its underlying liability?
The liability — spent-fuel disposal and reactor decommissioning — has a time horizon measured in decades for dismantling and millennia for geological storage. This forces a portfolio designed for solvency over liquidity, with a heavy tilt toward green bonds and pan-European commercial real estate. The asset mix is built to match the delayed, lumpy cash outflows of nuclear cleanup rather than to optimize for near-term returns.
What is the fund's relationship with the Net-Zero Asset Owner Alliance?
The fund joined the UN-convened Net-Zero Asset Owner Alliance in 2020, becoming the first sovereign-affiliated nuclear-liability vehicle to do so. Membership signals a commitment to align the portfolio with net-zero emissions targets, which is structurally consistent with a mandate that already positions environmental remediation as its core purpose. The fund also adheres to PRI principles and participates in INREV for its real estate activities.
How is the fund governed, and who provides oversight?
Udo Philipp chairs the Board of Trustees while concurrently serving as State Secretary at Germany's Federal Ministry for Economic Affairs and Climate Action. The fund operates under investment guidelines issued by the German Federal Ministry of Finance, which acts as the supervisory authority. This cross-border governance structure — Swiss operational management under German regulatory oversight — reflects the transnational dimension of nuclear liability in Central Europe.
Does the fund invest in nuclear energy or related infrastructure directly?
No. The fund's purpose is to finance the disposal and decommissioning of nuclear facilities, not to invest in nuclear energy generation or supporting infrastructure. Its known asset classes are green bonds, global fixed income, and pan-European commercial real estate. There is no public record of equity positions in nuclear operators or uranium supply chains.
What structural guidance shaped the fund's design?
During its establishment in 2000, the fund received structural guidance from AP4, Sweden's Fourth National Pension Fund. AP4's experience with liability-driven investing for long-dated public obligations provided a template for how a statutory nuclear waste fund could manage asset accumulation against a deferred, near-permanent liability. This influence is reflected in the fund's allocation architecture rather than in any ongoing operational relationship.
