Open the CIPO recordAbstract From the Canadian patent
A device for passively inerting the gas mixture forming in the reactor containment of a nuclear power plant in an accident situation is proposed, which device is based on the use of chemical substances which react or disintegrate releasing an inerting gas or gas mixture when a certain temperature of reaction is reached. This device is especially suitable for use in connection with catalytic recombiners for removing hydrogen through oxidatioxi with the oxygen present. The heat resulting from this exothermic process of recombination can be put to use for heating up chemical substances to the required temperature these having temperatures of reaction that lie above the temperature …

Why it's free to use
- Filed August 9, 1994 and granted April 18, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 9, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 9, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
