4883637, Nov 28, 1989

Filed:

Aug 25, 1988

Appl. No.:

7/236204

Inventors:

John D. McDaniel - Duluth GA

Assignee:

Nuclear Assurance Corporation - Norcross GA

International Classification:

G21F 500

US Classification:

376272

Abstract:

A closure arrangement for spent nuclear fuel shipping container has a lid member with a peripheral groove in its outer edge, the lid member being adapted to rests upon a shoulder within a bore at the mouth of the cask. The lid is forced into sealing engagement with the shoulder by a plurality of radially disposed wedges extending from the inner wall of the cask into the peripheral groove. The wedges are moved by bolts extending through the wall of the cask and cam the lid down against the shoulder as they are forced into the groove.

Appl. No.:

7/831404

Inventors:

John D. McDaniel - Duluth GA

Assignee:

Nuclear Assurance Corporation - Norcross GA

International Classification:

G21C 1932

US Classification:

376261

Abstract:

A tool guide plate for use in a rod consolidation system for the consolidation of spent fuel rods within a storage container. The system utilizes a robot in conjunction with long reach tools to remove spent fuel rods from an array of rods in a rod assembly and to transfer them to a rod consolidation holder. The tool guide plate has a plurality of apertures shaped to receive the end of a tool and less than the number of rods in the array and has means located on the guide plate for indexing the apertures over the rod position to provide tool access to all of the rods in the array, the apertures providing access to a plurality of rod positions in each index position.

Appl. No.:

7/984881

Inventors:

John D. McDaniel - Duluth GA

Assignee:

Nuclear Assurance Corporation - Norcross GA

International Classification:

G21C 1900
G21F 928

US Classification:

376260

Abstract:

A grid crusher apparatus and method are provided for a nuclear fuel rod consolidation system. Spacer grids are crushed within a basket which is then placed in a storage canister. The grid crusher apparatus has a ram assembly and a basket driving mechanism. The ram assembly has a sleeve ram and a central ram. The sleeve ram surrounds the central ram which is longitudinally movable within the sleeve ram. The central ram protrudes from the sleeve ram at a ram contact end and is retractable upon application of a preselected force to the central ram so that the central ram is flush with the sleeve ram at the ram contact end. The basket driving mechanism is configured to move the basket containing a spacer grid towards the ram contact end so that the spacer grid is crushed within the basket. The spacer grid is crushed by the combination of successive forces from the central ram and the sleeve ram, respectively. Essentially, the central portion of the spacer grid is crushed first, and then the remaining outer portion of the spacer grid is crushed to complete the crushing action of the spacer grid.

Appl. No.:

10/155177

Inventors:

Alan Gravitt - College Park GA, US
John McDaniel - Douglasville GA, US

International Classification:

C01B011/02

US Classification:

423/477000, 423/478000

Abstract:

An aqueous solution of metal chlorate, mineral acid and a reducing agent are continuously or intermittently sprayed, in a pattern to achieve intimate mixing, into a spherical chamber creating an aqueous foam reaction mixture generating chlorine dioxide which is removed in a direction 90 degrees to the axis of the spray nozzles. A baffle plate may be used to reduce the open cross sectional area of the exit port to increase reaction efficiency. The reactants are a mineral acid and an alkali metal chlorate or chloric acid and a reducing agent such as hydrogen peroxide. The mineral acid is either diluted or concentrated sulfuric acid, hydrochloric acid, acetic acid, nitric acid or a blend thereof. The ratio of acid is greater than one and less than 3 kg acid per kg of ClOformed. The chlorine dioxide may be removed with a stripper column.

Appl. No.:

5/463308

Inventors:

Clarence A. Dickey - Atlanta GA
John E. McDaniel - Fairburn GA

Assignee:

Glasrock Products, Inc. - Atlanta GA

International Classification:

B43K 500
C08J 900
B32B 518

US Classification:

401198

Abstract:

A process is provided to form spherical thermoplastic particles that involves dispersing a thermoplastic powder in a liquid that is a partial solvent for the thermoplastic, breaking the dispersion into droplets, forming thermoplastic spheres by heating the droplets to a temperature sufficient to at least partially solubilize the thermoplastic and to evaporate the solvent. Unique products, including porous structures, may be produced from material formed by this process.
