Abstract

A vessel for both treatment of radioactive wastewater and disposal of radioactive waste contained therein. The vessel comprises a main vessel structure including a shell formed of a metal material and a liner integrally coupled to the interior surface of the shell. The liner is preferably formed of a plastic material, such as high density polyethylene. Waste treatment equipment for treatment of the radioactive wastewater is provided within the shell. Ion exchange resin is typically located in the main vessel structure which, when spent, constitutes the radioactive waste which is subject to disposal. The vessel is preferably configured to function as a High Integrity Container (HIC).

Claims (21)

1. A vessel for both treatment of radioactive wastewater and disposal of radioactive waste contained therein, said vessel comprising:

a main vessel structure including a shell that defines an interior surface, wherein the shell includes a top defining a top opening therein, said top opening adapted to receive and be closed by a lid when said main vessel structure is being used for disposal of the radioactive waste, wherein said shell is formed of a metal material;

a liner integrally coupled to the interior surface of said shell, said liner being formed of a plastic material and defining an interior space within said shell;

waste treatment equipment for treatment of said radioactive wastewater provided within said shell; and

at least one connector for connecting said waste treatment equipment to an external pipe located outside of said main vessel structure, wherein said at least one connector has an open end for removable connection to an open end of the external pipe, and wherein said open end of said at least one connector is located within said interior space and is positioned proximate to and below said top opening, whereby said at least one connector is accessible through said top opening for connection to said external pipe when said vessel is being used for treatment of radioactive wastewater.

2. The vessel of claim 1 , further comprising a bed of ion exchange resin located inside said interior space, wherein said ion exchange resin, when spent, constitutes said radioactive waste which is subject to disposal.

3. The vessel of claim 1 , wherein said metal material is stainless steel.

4. The vessel of claim 1 , wherein said plastic material of said liner comprises high-density polyethylene.

5. The vessel of claim 4 , wherein said liner is molded to the interior surface of said shell.

6. The vessel of claim 1 , wherein said liner is molded to the interior surface of said shell.

7. The vessel of claim 6 , wherein said liner has a thickness of no greater than approximately ⅜ inch.

8. The vessel of claim 1 , wherein said shell further comprises a body and a bottom.

9. The vessel of claim 8 , wherein said top and said bottom of said shell are substantially planar and parallel to each other.

10. The vessel of claim 9 , wherein said body is cylindrical.

11. The vessel of claim 9 , further comprising a plurality of lift lugs attached to said body at spaced apart locations about a circumference thereof, said lift lugs extending above said top.

12. The vessel of claim 1 , further comprising

a lid attachable to said shell and configured to cover said top opening.

13. The vessel of claim 12 , wherein said waste treatment equipment includes a piping network disposed within said interior space, said piping network connected to said at least one connector to direct a flow of radioactive wastewater through said waste treatment equipment.

14. The vessel of claim 13 , wherein said at least one connector includes at least one inflow connector having an open end for removable connection to an open end of an external inflow pipe and at least one outflow connector having an open end for removable connection to an open end of an external outflow pipe.

15. The vessel of claim 14 , wherein said inflow connector and said outflow connector are accessible via said top opening defined in said top of said shell.

16. The vessel of claim 15 , wherein the open end of said inflow connector and the open end of said outflow connector are positioned within said interior space so as not to interfere with placement of said lid.
