A beam pipe (46) for guiding in an accelerator-driven nuclear system an accelerated particle beam (44) through a coolant in a primary vessel (12) onto a spallation target (30) comprises, preferably near its tip end (48) a , temperature triggered flooding device including for example a melt-rupture , disc. In case of an abnormal temperature increase in the system the , temperature triggered flooding device establishes below the normal coolant , level (16), a flooding communication between the vessel (12) and the interior of the beam pipe (46), thereby flooding the interior of the beam pipe (46) with the coolant (14) contained in the vessel (12).

Why it's free to use
- Filed July 6, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 6, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 6, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
