Passive venting arrangement of stoichiometric hydrogen plus oxygen gases generated in a shielded container
A passive venting arrangement for use in venting gases produced by radioactive materials. The arrangement includes a source gas region for receiving the gases and a filter ullage region disposed above the source gas region and segregated therefrom. A removable lid includes the filter ullage region and a plurality of bore holes. Each bore hole extends between, and fluidly couples, the source gas region and the filter ullage region. The arrangement also includes a plurality of filters disposed in contact with the filter ullage region. Each filter is structured to provide for an exchange of gases from the filter ullage region through the filter to an ambient environment.
1. A passive venting arrangement for use in venting of gases produced by radioactive materials, the venting arrangement comprising:
a source gas region structured to receive the gases produced by the radioactive materials;
a filter ullage region disposed above the source gas region and segregated therefrom except for a plurality of bore holes which each extend between, and fluidly couple, the source gas region and the filter ullage region; and
a plurality of filters disposed in contact with the filter ullage region, wherein each filter is structured to provide for the exchange of gases from the filter ullage region through the filter to an ambient environment,
wherein the filter ullage region and the plurality of bore holes are defined in a removable lid.
2. The passive venting arrangement of claim 1 , wherein the plurality of bore holes comprises at least three bore holes.
3. The passive venting arrangement of claim 1 , wherein the source gas region is structured to house the radioactive materials.
4. The passive venting arrangement of claim 1 , wherein the source gas region is structured to receive the gases produced by the radioactive materials which are contained in a source gas location separate from the source gas region.
5. The passive venting arrangement of claim 4 , further comprising a vent pipe which is structured to fluidly couple the source gas region and the source gas location.
6. The passive venting arrangement of claim 5 , wherein the source gas region is defined in-part by a cone shaped region surrounding an opening of the vent pipe to the source gas region.
7. A containment vessel for use in storing radioactive materials, the containment vessel comprising:
a body defining a source gas region therein which is structured to house the radioactive materials;
a filter ullage region defined in the body above the source gas region and segregated therefrom except for a plurality of bore holes defined in the body which each extend between, and fluidly couple, the source gas region and the filter ullage region; and
a plurality of filters disposed in contact with the filter ullage region, wherein each filter is structured to provide for the exchange of gases from the filter ullage region through the filter to an ambient environment,
wherein the body comprises a removable lid, and wherein the filter ullage region and the plurality of bore holes are defined in the lid.
8. The containment vessel of claim 7 , wherein the plurality of bore holes comprises at least three bore holes.
