Claim Text:
1. A method for filtering a waste stream of water from a nuclear power plant according to its isotopic forms, the method comprising the steps of: receiving a waste stream of water from a nuclear power plant, wherein the waste stream comprises at least two distinct isotopic forms of water; heating the waste stream of liquid water to form a gas comprising at least two distinct isotopic forms of water; passing at least a portion of the gas through at least one laminated graphene oxide membrane comprising a plurality of graphene oxide sheets coupled together in a layered, interlocking structure; and using the at least one laminated graphene oxide membrane to separate the gas into a permeate and a retentate, wherein the permeate comprises an increased concentration of light water relative to the retentate.
