- Decontaminating surfaces in a liquid environment?

- Removing hot spots in pipes?

- Decontaminate surfaces using a dry process?

- Unclogging and removing dust from filters?

Ultrasonic waves can be used in liquid, solid or air environments.

Wave propagation will depend on the nature of the substrate (density, elasticity, etc.) and the ultrasonic frequency used.

The equipment can be adapted to meet your needs.

- Remove fixed contamination on stainless steel?
- Improve the final surface to reduce subsequent contamination ?
- To have a portable or even autonomous battery-powered device ?

A new implementation: the rigid pad is cleverly replaced by a carbon fibre brush,
New series-produced portable rectifiers,

Efficient decontamination method which fulfills important requirements in the nuclear industry :

- dry process

- does not generate waste (no input of materials or chemicals)

- removes fixed contamination in the form of oxides, paints, thin layers of grease...

- Can be used in both manual and remote mode

Tools specifically designed to decontaminate

radiologically and/or chemically
polluted surfaces (asbestos, lead,
etc.) :

- on floors, walls and ceilings

• Concrete, plaster.. stripping,
• Paint removal from metal or concrete surfaces.

With a full system of dust collection "at source" and waste conditioning.

Adaptable tools to manual or semi-automatic machines.

If you want to reduce workers hardship, reduce dust emissions and increase efficiency...

Nochar produts (USA) are engineered polymers allowing via irreversible mechanisms to absorb organic and/or aqueous liquid thus generating a solid and stabilized waste

The Nochar polymers offer an innovative solution to nuclear sites that require a treatment process to deal with complex organic/aqueous waste streams: multiphase liquid wastes, suspended matter, various uncharacterized compositions .

Applications:

• Mixed sludge types; oil, oil-water with other solid contaminants such as salt, sand, dirt
• Pump and machine oil, various types of synthetic and standart oil
• All organic liquids including scintillation cocktails, tri-butyl phosphate (TBP)
• Aqueous liquids; water, low pH acid, high pH alkaline solution
• Resin bed sludge, activated carbon slurry

Innovative, differentiating processes that can meet the needs of companies in the nuclear sector

• Expertise in key technologies in the field of nuclear decontamination and wastes treatment

Support you in your research of efficient solutions

Frédérique DAMERVAL

 With 25 years of professional experience within ORANO (formerly AREVA), from Research Manager to Innovation Director, recognized as an AREVA senior expert in the field of decontamination and waste treatment, I have always been looking for new processes.

Today, with the launch of this site, I want to continue to highlight technologies in the field of decontamination and waste treatment.

I also provide training on decontamination processes for the INSTN, the École des Ponts and the ISTP and I provide technical assistance for studies and projects., response to calls for tenders  in my field of expertise (Decontamination and Effluent/Waste Treatment)
