Nuclear Pumps

RADIOACTIVE LIQUIDS PUMP MANUFACTURER

The operation of a nuclear facility necessarily involves the use of critical environments with extreme temperature, radiations, or magnetic fields, that are hazardous to humans and the environment. OPTIMEX canned motor pumps are particularly well suited to this type of liquid since their double containment and the absence of dynamic sealing reduce the risk of leakage to a minimum. As a result, OPTIMEX canned motor pumps successfully maintain the integrity safety function. Canned motor pumps for radioactive liquids also ensure that the operability safety function is maintained over time thanks to the absence of friction under normal operating conditions and therefore a lower failure rate and fewer maintenance operations.​

PUMPING RESTRICTIONS FOR RADIOACTIVE LIQUIDS:

Pumping a radioactive liquids involves:​

 OPTIMEX SOLUTIONS:

OPTIMEX canned motor pumps have the following features for pumping radioactive liquids and meeting the associated constraints:​

•  Reduce the risk of leakage to a minimum​
• Selecting materials compatible with the level of irradiation​
•  Avoiding the detachment of particles which could become activated and increase the overall radioactivity level of the system​
•  Avoiding liquid retention zones​
•  Minimising the risk of corrosion

•  Removal of cast parts from the pressure barrier​
• Stainless steel construction with controlled cobalt content​
•  Use of PMUC products​
•  Reduction in the number of welds and preference for parts fully machined​
•  Selection and qualification of non-metallic materials, in particular electric motor components​
• Reduction of roughness, particularly that of cast internal parts​
•  Fully drainable equipment

Examples of nuclear process:

  •   Primary water and drain​
  •   Secondary coolant​
  •   Borated water and boric acid​
  •   Demineralised water
