Nuclear industry applications

An organisation designed
to satisfy the requirements
of the nuclear industry

CTP environnement deploys its expertise within nuclear power plants, on fresh or spent fuel processing sites and on nuclear research sites.

The dedicated Nuclear Division is equipped with a robust management system, highly trained teams, nuclear-capable equipment and specific controlled operating procedures. The safety, security and radiation protection benchmarks, as well as the related quality requirements, are incorporated and implemented.

CTP environnement’s culture of innovation and flexibility provides a unique response to the needs of the nuclear industry in its various operational domains: cleaning and maintenance, along with chemicals and the environment.

Internal and external process cleaning, liquid-waste treatment

Mechanical or chemical cleaning operations are carried out on all kinds of heat exchangers or circuits: condensers, tubular heat exchangers of all sizes, plate heat exchangers, boilers, air cooled heat exchangers, etc.

All kinds of damaging residues can be removed: greasy substances, limescale, sludge, corrosion, contaminated deposits, etc. Online analytical monitoring is used to monitor the treatment’s performance and guarantee the harmlessness of the client’s facilities.

See an example of our operations

CTP environnement determines and adopts a suitable controlled, mechanical or chemical, wet or dry, online or offline solution for every need, in line with the operation’s particular constraints.

Operations in radioactive environments

Our skids and mobile units can be made nuclear-capable, in order to meet the needs of working in a controlled zone or radioactive environment. They include cutting-edge technologies and equipment for treating your radioactive waste and contaminated systems, thereby decontaminating your facilities and drastically reducing the quantities of radioactive waste.

CTP environnement’s teams are highly trained and experienced, enabling them to work effectively in safe and secure conditions, whatever the operational constraints.

Treatment of radioactive effluent from a nuclear power plant’s reactor building

Online dewatering of sludge generated by the hydrodemolition of concrete blocks

CTP environnement was asked to define and implement a solution for treating effluent generated by the partial demolition of a reactor building’s structure for subsequent renovation. The effluent in question was liquid sludge containing mineral matter (demolished concrete) and metal (descaled steel) at a concentration of 5 to 20 g/L.

Treatment of effluent generated by cleaning the condenser at a nuclear power plant

Removal of metals using a physico-chemical Clearflow® mobile treatment unit

Steam condensers in nuclear power plants are made up of several smaller condensers, which themselves comprise approximately 21,000 metal tubes circulating cooling water. Due to the hardness of water drawn from the natural environment, the cooling tubes are subject to regular and significant scaling and need to be cleaned using ultra-high-pressure water jets (UHP).

Chemical cleaning of an air-cooled heat exchanger for a nuclear plant’s pool water

Descaling a cooling tower by chemical circulation

CTP environnement’s teams were contracted to clean a 12 m (39 ft) long and 4 m (13 ft) high heat exchanger, which equated to approximately 2 tons of residue, primarily made up of calcium carbonate (CaCO3).

Bypass for the production of higher quality water in nuclear power plants

Supply of temporary solution including mobile tanks, physico-chemical treatment and filtration skid

CTP environment implemented a complete bypass of the site's high-quality water production. This production used river water and storm water as a feedstock. Once produced, it supplies the potable and demineralised water chain production of the site. Continuity and uninterrupted service is a necessity for the site.

REUSE of stripping effluents from nuclear power plant

Treatment of stripping effluent from a boiler structure in preparation for a surface coating renovation application

CTP environnement set up a treatment solution that provided the customer with several reuse options:

  • Recycling on an ultra-high pressure stripping unit with the following water quality constraints:
    T° < 30°C, pH 6-8, TSS < 5 ppm, COD < 20 ppm, metals < 5 ppm, conductivity < 1000 µS/cm2
  • Refrigeration of pre-treated water
  • Washing and rinsing water

Victory at the V.I.E Grand Prix Americas 2025

To accelerate its international growth, CTP environnement group has embraced the V.I.E program, led by Business France and backed by the French government. For several years, qualified young talents have been strengthening our teams in subsidiaries located in Singapore, Canada, the USA, and more recently, the United Kingdom.

In our American subsidiary based in Houston, Neyl stood out brilliantly by winning first place at the V.I.E Grand Prix Americas 2025, an award that recognized 4 winners out of 97 candidates. His original and impactful video—highlighting France as THE go-to destination for innovation and investment—made all the difference.

INTERSOL 2025

We took part for the first time in the 24th edition of INTERSOL, the International Congress and Exhibition on Soils, Sediments and Water.

Our teams came to meet the leading players in the field of polluted sites and soils (PSS), to compare their challenges and solutions, and to respond in the best possible way.

CTP environnement joins the 2nd French "Accélérateur Nucléaire" programme

BPI France has been supporting our development for many years, even before the creation of our nuclear division in 2015.

10 years later, on the strength of our recent experience, which has been recognised by major players in the sector, we decided to join their Nuclear Acceleration Programme, launched in 2024.
