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).
