TRITIUM SAMPLER WITH 2 VIALS (WITHOUT OVEN) - MARC 5000

What do I measure ?

By analyzing the collected water solution in a laboratory, you will measure the volumic activity of the tritium contained in the sampled air

APPLICATIONS Nuclear power plants. Industrial use of tritium. Research on impact of nuclear contamination levels. Nuclear medicine. OFFICIAL PROVIDER OF FRANCE IRSN (radio protection and nuclear security institute). National Marine. EDF (French Electricity Company). ANDRA (National Agency for the management of radioactiv wastes). CEA (nuclear research institute) INTERNATIONAL IAEA (International Atomic Energy Agency). Various nuclear power plants in Europe and the world.

This tritium sampler brings original solutions in the exploitation of trapping systems for tritium gas and tritiated water. This collection system is mainly used for the detection of chimney rejects and TRITIUM wastes degassing. The realization of this machine has been essentially focused on optimum sampling efficiency associated with ergonomics adapted to all utilization conditions. The technician can come less frequently to collect the liquid solution (monthly instead of a usual weekly frequency) thanks to a cooling system water circuit that will prevent all water loss by evaporation in the feeding-bottles. Its original tightness dynamics system on the two feeding-bottles, authorizes a manipulation (on/ off) particularly confoftable of this device in all circumstances without pressing back nor loss of solution. A microprocessor pilots and manages all functioning parameters, insuring thus a total security in its utilization during long periods.

Working principle
This device traps the tritiated water vapor by a principle of paddling in two feeding-bottles. The collector sucks up atmospheric air through a meter which precisely measures the quantity of aspired air. This air runs successively through two bottles that trap the tritiated water vapor. After a certain time, the tritiated water contained in the bottles is measured in a laboratory. The quantity of tritium measured is related to the volume air which passed in the equipment.

Standard equipment

The MARC 5000 standard model is delivered fully equiped with feeding bottles, microprocessor, etc. Please note that the cooling system is optional. SDEC France provides in situ delivery, training and after sales services.

What is the use of the cooling system (option)

Under ambiant temperature, there is always a small evaporation of the solution. This can alterate the accuracy of the sample when the solution isn't collected every day. The cooling system maintains a low temperature in the trapping liquid solution. It can then be collected for further analysis on a week or even month frequency.

What is the use of the pressure regulator (option)

The pressure regulator is mainly used when the equipment is placed in a room where high pressures are applied.

Why isn't there an oven with this model?

Because in some cases, there isn't any need to measure the form of the radionucleid which would be transformed by oxidation.
