"Modern tokamaks are large, heavy and powerful machines that can be brought down by a mere pinhole in their vacuum system or piping networks. Whether microscopic or visible, holes, cracks and faults cause leaks, which in turn allow air, water or helium to diffuse into areas that are forbidden to them. At best, a leak can seriously degrade the machine's performance; at worst it can stop operations.
.... Beginning last year, an intense R & D program was started to develop risk-mitigating concepts linked to leak localization. Tasks have been launched in collaboration with the US and European Domestic Agencies, with Russian facilities, and a first industrial contract for leak localization simulations has recently been awarded to the French-Indian company FLUIDYN.
Last week, the ITER Vacuum Pumping Section held a kick-off meeting with the Fluidyn specialists. "We've asked them to model leaks from the high pressure water circuits into the vacuum vessel," explains ITER Vacuum Pumping Section Leader Robert Pearce and Leak Technical Engineer Liam Worth. "This is highly complex and has never been done before. Modelling leaks in ITER is a "multiphysics" affair involving different physics models, one of which requires sixty-term equations that have just recently been mastered..."
As an innovative company, FLUIDYN has received the following distinctions:
Innovation award of SOLVAY
Flèches d’Or, trophy awarded by the Plaine Commune (Urban Community of 9 cities in Paris suburban area)
PM’UP 2011 Laureate
