Automated and Robotized Glove Box Systems
ALSYMEX designs and manufactures equipment for glove boxes, incorporating high availability instrumentation and control, automation and robotization.
On new installations or dismantling projects, ALSYMEX intervenes for process and equipment nuclearization missions for contaminating environments, on maintainable and decontaminable mechanical and electromechanical systems and processes (conveying, handling, machining, characterization, etc.).

Automated and Robotized Hot Cell Systems
ALSYMEX designs automated systems that can be robotized and hardened for specific use in hot cells. The solutions deployed by ALSYMEX enable highly reliable remote operation where activity levels are high. ALSYMEX manages all specific constraints associated with exposure and maintainability of shielded cell equipment, in particular compatible materials, connectors, and electrical and mechanical penetrations and shielding.
Entirely remotely controllable for hot cell assembly and dismantling, the solutions developed by ALSYMEX enable equipment to be used in high activity exposure conditions and allow for remote operation (special connectors, shielding, special materials).
The constraints associated with contamination, material retention, grip and handling of parts (geometries and weights), radiation, ageing and material compatibility are taken into consideration.

Compaction Systems
ALSYMEX designs and manufactures barrel compacting products and solutions for the nuclear industry, helping to reduce the volume of very low-level waste generated by nuclear installations, in order to increase storage capacity and volume.
ALSYMEX is also developing compacting solutions for canisters, aerosols and other tanks, with effluent recovery, containment filtration and radiological atmosphere monitoring to reduce waste volumes.

Containment Solutions
ALSYMEX designs and manufactures instrumented glove boxes for nuclear facilities.
For applications that call for class 1 shop-fabricated stainless steel glove boxes, ALSYMEX manufactures tailored equipment incorporating all of the constraints of nuclear sites relating to the handling, transfer, transformation of radioactive material in a containment, or under a controlled neutral gas atmosphere.
With rich knowledge and expertise, ALSYMEX takes into account ventilation classes (renewal rate, dynamic containment), static containment classes (leak rate) and other specifics of the application (e.g. materials in fluid, gas or solid form), especially in glove box applications calling for mechanical processes, fluids or gases imposing specific operating constraints (T°, P, PH, H2, O2).

Heat Exchangers
ALSYMEX designs and manufactures a line of high-performance heat exchangers consisting of superimposed pre-machined plates providing channel geometries dedicated to each application. Assembly of these individual plates calls for metallic bonds produced by a diffusion welding technique assisted by Hot Isostatic Pressing (HIP).
This technology, which involves high pressures and temperatures on the parts to be assembled, allows for welding at the heart of the material, not just on the surface. It enables the plates to be welded consistently with no added material, an operation that is impossible using more traditional techniques.

Hot Cell Characterization Test Benches
ALSYMEX has developed a system for characterizing and analyzing materials and/or nuclear fuels, by cutting, compression, traction and drilling.

Radioactive Powder Pressing
ALSYMEX designs and manufactures electromechanical or electrohydraulic presses intended for the production of nuclear fuels of different sizes and geometries, for laboratory applications, in glove boxes or shielded cells.

ALSOLEN develops medium-power Fresnel reflector solar thermal power plants (up to 100 MWth or 20 MWe) known by the same name, ALSOLEN. These plants use oil as the heat transfer fluid and have a direct rock-bed thermocline thermal storage system. The heat transfer fluid reaches a temperature of 300 °C and transfers its thermal energy to applications that, depending on the needs of the user, can be combined between: electricity, industrial heat, cold and desalination of seawater. ALSOLEN solar power plants are more specifically designed for operation in an isolated or semi-isolated grid and require an operating level that is not very restrictive.
The originality of ALSOLEN solar thermal power plants lies in part in their design (incorporating as much of the manufacturing as possible on the site of installation itself thanks to the use of a mobile factory), their high performance, their low, easy maintenance, and their long service life. Integrated thermal storage is used to obtain operational autonomy suited to the needs of the user, even several hours after sunset.
The technology used for each application corresponds to the design strategy of ALSOLEN power plants. The applications of electricity generation use an Organic Rankine Cycle (ORC), the cold is generated by an absorption chiller enabling negative temperatures to be reached, and fresh water is achieved by multi-effect distillation.
All of the ALSOLEN power plant development work has been done in conjunction with CEA LITEN and ALCEN subsidiaries.
A high-power thermal solar power plant (50 MWe and above) called ALSOLEN SUP is at an advanced stage of development. ALSOLEN SUP technology will directly generate steam superheated to 450 °C and will have a three-stage thermal storage capacity. It will present specific clean innovations to the market and benefit from ALSOLEN innovations.
