Cleaning and decontamination in nuclear power plants and radioactive laboratories
The nuclear power stations and the laboratories handling radioactive materials require highly specialised cleaning and decontamination procedures. In these critical environments, process efficiency impacts not only safety, but also operational efficiency and equipment life.
In this article we explore:
- The challenges of clean-up in nuclear environments.
- Solutions through ultrasonic and high-pressure spray cleaning machines.
- How to choose detergents compatible with waste standards.
- Advantages of our technologies for nuclear technical cleaning.
Professional solutions for the removal of radioactive residues from technical surfaces with industrial cleaning machines
Clean-up challenges in nuclear environments
Radioactive waste has complex characteristics: it is sticky, persistent and requires safe handling.
Some of the main challenges are:
- Radioactive isotope contamination in reactor cavities, floors, walls, tools, PPE and equipment.
- Need for cleaning without the use of expensive removable coatings.
- Interference of some chelating agents with ion exchange treatment systems.
- Avoid secondary waste affecting the evaporation or storage of radioactive waste.
- Risk of embrittlement or corrosion of stainless steel by halides, sulphur or low melting point metals.
The clean-up must be compatible with the nuclear waste management processes and ensure the non-interference with disposal methods.
Effective technologies for nuclear clean-up
Ultrasonic cleaning for nuclear decontamination
The systems of ultrasonic cleaning use transducers which emit high-frequency sound waves, generating energetic cavitation.
This mechanical effect deep cleanslaboratory tools, contaminated technical glassware and removable pipes, valves and components.
Advantages:
- Penetrates complex geometries.
- Cleans without abrasion or mechanical damage.
- Compatible with mild alkaline detergents without ions.
Example of recommended detergents: Ion-free low-foaming detergents.
Pressure spray and soak cleaning
The systems of spray cleaningThe decontamination of nuclear reactor cavities, large surfaces (floors, walls) and reusable protective equipment, whether manual or automated, can be carried out in the decontamination of nuclear reactor cavities, large surfaces (floors, walls) and reusable protective equipment.
Applicable methods:
- High pressure spraying.
- Prolonged soaking with non-ionic alkaline detergent.
- Mechanical scrubbing with integrated systems.
These technologies allow isotope removal without the need for removable coatings, reducing costs and waste volume.
Which detergents are recommended?
According to nuclear cleaning standards, detergents must meet strict requirements:
- High purity: free of halides, heavy metals and sulphur.
- Compatible with evaporation and waste treatment.
- Non-interfering with ion exchange.
- Easy to rinse.
🔬 Detergents should facilitate the capture of the isotope and its subsequent treatment by controlled evaporation.
Advantages of cleaning machines for the nuclear sector
Our industrial cleaning solutions are designed to meet the most demanding standards in nuclear facilities.
Main advantages:
- Deep cleaning without damage: the ultrasonic cleaning machines clean inaccessible areas safely.
- Operational securityAutomated machines reduce operator exposure.
- Regulatory compliancedetergents and methods compatible with radioactive waste regulations.
- Less generation of secondary wastecompared to abrasive methods or volatile solvents.
- VersatilityCompatible with glass, stainless steel, electronic components and PPE.
Where is this technology applied?
- Nuclear power plants (containment areas, turbine rooms, reactor cavities).
- Nuclear research laboratories.
- Radioactive waste disposal facilities.
- Maintenance workshops in nuclear power plants.
- Manufacturers of nuclear fuel and recycling of fissile materials.
Recommendations for efficient nuclear decontamination
The clean-up and technical decontamination in nuclear environments requires safe, effective solutions that are compatible with international standards.
The ultrasonic cleaning machines and pressure spraying systems allow a higher degree of decontamination to be achieved, reducing risks to personnel and extending the life of critical equipment.
With these practices, facilities can ensure a controlled, safe and technically sustainable environment, protecting both people and the high-value assets of nuclear power plants and laboratories.
At IBERKLEEN we develop cleaning solutions capable of offering effective and sustainable solutions in nuclear power plant clean-up and radioactive decontamination.
