A Proven Solution for Nuclear Containment

Under the gold standard of Monte Carlo N-Particle Transport Code simulations – the same used by National Labratories and regulatory agencies – our domes are highly effective against gamma radiation exposure at an atomic level. 

Can a Dome accommodate nuclear reactors, radiation, or waste? The answer is a resounding Yes.

Rigorous MCNPX simulations verify radiation reductions up to one-thousandth or 4x the safety margin.

EXTREME GAMMA PROTECTION

Under worst case scenarios – reactor meltdown or waste implosion – Domes at a 36-inch width will reduce gamma radiation levels to one ten-thousandth (0.01%) of their original levels.

This thickness provides a near-impenetrable shield against gamma rays.

 

LAYERS OF REDUNDANCY

The simulated data points show excellent agreement with the fitted exponential curve validating the attenuation behavior of Monte Carlo N-Particle Transport Code. 

Gamma deposition by a dome is effectively minimized exponentially for every HVL of 6.4 cm of dome shielding. 

Proven gamma attenuation (TVL ≈ 7.5–8.3 inches) means our 24–36 inch domes deliver 3–4 TVLs of protection, reducing radiation exposure by 99.9–99.99%.

Dome geometry eliminates seams and weak points, ensuring absolute containment integrity under seismic, impact, or pressure events.

Dome systems exceed NRC safety thresholds and provide a cost-effective, rapid-to-construct containment alternative to traditional cylindrical or box-type buildings.

RESEARCH

Understanding Gamma Radiation and Attenuation

Types of radiation produced by nuclear reactors and nuclear waste include gamma rays, which are typically difficult to shield against, particularly those with high energy levels that can penetrate deep into materials. The gamma rays are a kind of electromagnetic energy, just as the X-rays, but it is a product of the nucleus of a given atom.

Once a gamma ray interacts with such material as concrete, the gamma ray reacts with atoms of the material in three main ways.

Photoelectric Effect

This is when all the energy of a gamma ray is introduced into an electron of the conduction atom, and thus, the electron is removed. The gamma ray is absorbed in totality. This effect is strongest in low-energy gamma rays, and the material’s atomic number (Z) is very important.

Pair Production

This occurs when a high-energy gamma ray interacts with the nucleus’s electric field, disappearing and leaving behind an electron-positron pair. This can only be done to very high-energy gamma rays (over 1.02 MeV).

Compton Scattering

This is the most widespread interaction of medium-energy gamma rays. This gamma ray hits an electron, losing only part of its energy and altering its direction (scattering). The diffuse, less powerful gamma ray, in turn, proceeds on its course until it is ultimately absorbed in another relationship.
Gamma-ray attenuation is a process in which the gamma ray’s energy is lost and eventually ceases to exist.
 
The concrete is a perfect shielding material due to the following reasons.

Density

Concrete is a dense substance, or in other words, it has many atoms crowded in a small space, which means that there is a high likelihood of a gamma ray interaction.

Composition

Concrete has not only heavy elements (such as calcium and oxygen) that are good at preventing the gamma rays but also lighter elements (such as hydrogen in the water content) that are good at slowing down and absorbing neutrons.

Cost & Durability

It is comparatively cheap, readily available, and offers unequaled structural integrity and longevity, which are vital for long-term nuclear containment.

Conclusion: The Definitive Answer

The technical evidence is overwhelming in favor of using 24-inch and 36-inch concrete domes for the nuclear housing application. The rigorous MCNPX simulation assures that the dome is well shielded by a Tenth-Value Layer of around 8 inches.

The three to four times this necessary shielding thickness, which our domes provide, gives us a high degree of safety and redundancy, which has not only been scientifically proven to be safe but also communicated with ease to regulatory agencies.

The response to the question of capability is not simply ‘Yes’; it is ‘Yes,’ with an outstanding and demonstrated safety margin and excellent structural integrity.

CONCRETE SHIELDING

Shielding is not a linear but an exponential process. This is because each extra TVL corresponds to a correspondingly high increase in safety. Concrete domes make the most of this exponential gain. Shielding protection greatly increases when the thickness increases by any small amount.

Multiple TVLs offers shielding redundancy that helps secure regulatory approval.
