Title: Gas concentrations in stratified atmosphere - are broken down by adding gas to one or more layers to change density at interface
Inventor: JAHN HERMANN DIPL ING
IPC: G21C9/00
Filed: 1978-02-09
Abstract: A method of breaking up local gas concns in stratified atmospheres, esp. in enclosed spaces such as the safety containment of a nuclear reactor, consists of introducing a relatively higher density gas into a gas layer of light density so as to create a combined density local to the layer below greater than that of the layer below, thus causing the upper layer to penetrate through the mix with the lower layer. Alternatively, a lighter gas can be injected into a lower layer to reduce its density to less than that of the layer above. Other combinations are also possible, the general principle being to change the density near to the interface between two layers to induce mixing between the layers. The method does not rely upon mechanically driven blowers or other equipment within the containment.
