Abstract
The present invention relates to a system and method for removing dissolved gas from makeup water in a water-cooled nuclear reactor. The present invention includes a storage tank for containing the makeup water that includes the dissolved gas, a membrane system positioned downstream of the storage tank to at least partially remove the dissolved gas front the makeup water; and a transport mechanism to transfer the makeup water from an outlet of the membrane system for use in the water-cooled nuclear reactor. The dissolved gas can include at least one of dissolved oxygen, dissolved nitrogen, dissolved argon and mixtures thereof.
Claims18
A system for at least partially removing dissolved gas from makeup water for use in a water-cooled nuclear reactor, the system comprising:
- a storage tank having a discharge, said tank containing the makeup water including the dissolved gas;
- a membrane system having an inlet and an outlet, said membrane system positioned downstream of the discharge of the storage tank to receive the makeup water and to at least partially remove the dissolved gas from the makeup water;
- and
- a transport mechanism to transfer the makeup water from the outlet of the membrane system for use in the water-cooled nuclear reactor.
A method for at least partially removing dissolved gas from makeup water in a water-cooled nuclear reactor, the method comprising:
- providing a storage tank to contain the makeup water that includes the dissolved gas;
- discharging the makeup water from an outlet of the storage tank to an inlet of a membrane system;
- passing the makeup water through the membrane system;
- at least partially removing the dissolved gas from the makeup water in the membrane system;
- and
- transporting the makeup water from an outlet of the membrane system to an end-user selected from the group consisting of components and/or systems in the water-cooled nuclear reactor.
