Abstract
Abstract A metal compressible bellows-type canister for use in a hot uniaxial pressing process of a mixture of high level radioactive nuclear waste material and a synthetic rock-forming material.The canister (1) comprising bottom wall(s) convoluted bellows like side wall (13), top wall (6) and two transverse metal apertured plates (12,12') dividing the canister into three equally spaced regions. Preferably the apertures (14, 14') are of a clover leaf configuration and are located at the centre of the plates (12,12'). Spaces (16,16', 16") are provided between _ a liner (15) and the convoluted side wall (13) to enable hot pressing of the canister (1) without hinderance from the moisture that would otherwise enter the convolutions.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
63 words
A metal container for heating solid particulate material contained therein, which container (1) is characterised by a thin outer wall (3) of generally cylindrical form and at least one apertured plate (2) which is of thermally-conductive material and which extends generally transversely and interiorly of the container (1) and is attached in thermally conducting relation to the outer wall (3) of the container.
Claim 2
Dependent Claim
63 words
A metal container for heating solid particulate material contained therein, which container (1) is characterised by a thin outer wall (3) of generally cylindrical form and at least one apertured plate (2) which is of thermally-conductive material and which extends generally transversely and interiorly of the container (1) and is attached in thermally conducting relation to the outer wall (3) of the container.
Claim 3
Dependent Claim
42 words
A container according to claim 1, characterised in that the or each plate (12. 12') is of a metal having high thermal conductivity and extends in a plane normal to the axis of the container and around which said outer wall extends.
Claim 4
Dependent Claim
33 words
A container according to claim 1 or claim 2, characterised in that the aperture (14, 14') in plate (12. 12') is substantially centrally located therein and is substantially of a four-leaf clover configuration.
Claim 5
Dependent Claim
87 words
A container according to any one of claims 1 to 3, characterised in that container (1) is substantially cylindrical and has a bellows-like wall (13) and the or each apertured plate (12, 12') is of a strength sufficient to prevent gross radial deformation of the container and displacement of end walls of the container (1) transversely to the axis of the container (1) during a hot uniaxial pressing of the container along an axis at right angles to the general plane of the or each apertured plate.
Claim 6
Dependent Claim
52 words
A container according to any one of claims 1 to 4, characterised in that a plurality of said apertured plates (12, 12') are provided, the plates being metal and placed at substantially equally spaced intervals within and along the length of the container (1), the plates being welded to the outer wall.
Claim 7
Dependent Claim
65 words
A container according to claim 4, characterised in that at least one cylindrical screen (15) is located adjacent the bellows-like wall (13) of the container and extends between the upper and lower limits of each compartment defined between each apertured plate or plates (12. 12') and the ends of the container (5, 6) for the purpose of preventing the particulate material entering the bellows convolutions.
Claim 8
Dependent Claim
44 words
A container according to claim 6, characterised in that a series of holes (9) are positioned around the periphery of the or each apertured plate (12, 12') to enable air transfer between different compartments formed between the liner (15) and adjacent bellows convolutions (13).
Claim 9
Dependent Claim
28 words
A container according to either claim 6 or 7, characterised in that Zircaloy is placed in the compartments formed between the liner (15) and the container convolutions (13).
Claim 10
Dependent Claim
21 words
A method according to claim 1, wherein the container (1) is as claimed in any one of claims 3 to 10.
Claim 11
Independent Claim
103 words
A method of heating material within a container characterised by the the steps of: providing a container (1) with at least one apertured plate (2) which is of a thermally-conductive material and which extends generally transversely and interiorly of the container (1) and is attached in thermally conducting relation to the wall of the container; at least partially filling the container (1) with a solid particulate material to be heated therein, such that the or at least one of the apertured plates (2) is embedded in the material: and applying heat to the container (1) for heating the container (1) and its contents.
Claim 12
Independent Claim
103 words
A method of heating material within a container characterised by the the steps of: providing a container (1) with at least one apertured plate (2) which is of a thermally-conductive material and which extends generally transversely and interiorly of the container (1) and is attached in thermally conducting relation to the wall of the container; at least partially filling the container (1) with a solid particulate material to be heated therein, such that the or at least one of the apertured plates (2) is embedded in the material: and applying heat to the container (1) for heating the container (1) and its contents.
