Request for Scientific Examination

 

To: [University Name, Institute for Nuclear Engineering or Materials Science]

Dear Sir or Madam,

I would like to draw your institution’s attention to a pioneering scientific question that could open new avenues in both decommissioning and nuclear waste disposal research:

Would your university be interested in exploring a high-temperature decay test aimed at accelerating radioactive decay—based on the repurposing of decommissioned nuclear power plant cooling towers as thermal final repositories and energy storage systems?

For decades, I have been developing a concept ("Hoyer Solutions") that sees the remaining cooling towers of nuclear power plants as an opportunity for a dual purpose:

  • Storage of low- and intermediate-level radioactive materials from decommissioning

  • Long-term thermal treatment of these materials using surplus renewable energy

  • Integration into a Hoyer Hydrogen Center via solid-state storage

  • Electricity generation through the Hoyer Parabolic Mirror Heating System and zero-electricity buffer storage from 30,000 wind turbines and photovoltaic systems

A core aspect of this approach is the layered storage of contaminated materials, alternating with neutral, temperature-stable substances to ensure both physical separation and uniform heat distribution. This results in stable thermal storage zones within the cooling towers.

Technical Implementation Includes:

  • Hoyer Parabolic Mirror Heating System (up to 900 °C)

  • Hoyer Sphere Heater with soapstone layers (up to 1,900 °C, powered by surplus wind energy)

Hypothesis:

A continuous high-temperature treatment could significantly accelerate radioactive decay by inducing structural changes at the nuclear level, thereby offering a safer and more cost-effective solution to nuclear waste management.

Key Figures and Assumptions:

  • Approx. 25 cooling towers still available

  • Potential usable volume: approx. 5 million m³

  • Estimated decommissioning waste by 2060: approx. 600,000 t (excluding high-level radioactive material)

  • Utilizing existing nuclear infrastructure could reduce dismantling costs by approx. €25 billion (for 17 facilities)

  • Cooling towers could also serve as thermal buffer storage for surplus wind energy and extreme weather scenarios

Objective:

I seek to collaborate with scientific institutions such as yours to examine whether a high-temperature decay test (e.g., within an existing cooling tower) is both feasible and physically verifiable.

I firmly believe that such a pilot project could achieve considerable scientific and technological impact—both nationally and internationally. I would be delighted to receive your feedback and remain available for further explanations, sketches, and models.

Best regards, Eric Hoyer
