Open the CIPO recordAbstract From the Canadian patent
A nuclear power plant which includes a closed loop power generation circuit making use of helium as the working fluid. The plant further includes a helium inventory control system which includes a plurality of helium storage tanks whereby helium can be fed into or removed from the power generation circuit. Each helium storage tank is provided with a heat sink so that the tank has a relatively high thermal inertia which in turn restricts the temperature variation within the storage tank as a result of the introduction of helium into and/or the withdrawal of helium from the storage tank. This permits the optimization of the design of the storage tanks.

Why it's free to use
- Filed February 28, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 28, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 28, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
