US Classification:

376438, 376409, 376426, 376434

Abstract:

A nuclear fuel assembly support grid formed from an array of a plurality of orthogonally arranged straps in an egg-crate configuration with angled trailing and/or leading edges that are designed to break the correlation of vortices shed from the edges of the grid straps by varying the phase of the vortices to avoid resonant vibration of the straps.

Appl. No.:

12/102123

Inventors:

Yong LU - Columbia SC, US
Xiaoyan Jiang - Columbia SC, US

International Classification:

G21C 3/34

US Classification:

376438

Abstract:

An improved grid for a nuclear reactor fuel assembly that has an egg-crate base grid as the primary support structure with each support cell of the base grid that supports a fuel rod having a lock-support sleeve that is rotatable within the support cell between a first and second orientation. In the first orientation the lock-support sleeve fits loosely within the support cell of the base grid and respectively, loosely receives the fuel rods that are loaded therein. The lock-support sleeves are then rotated to a second orientation that locks the fuel rods axially within the support cells.

Abstract:

A nuclear fuel assembly support grid formed from an array of a plurality of orthogonally arranged straps in an egg-crate configuration with angled trailing and/or leading edges that are designed to break the correlation of vortices shed from the edges of the grid straps by varying the phase of the vortices to avoid resonant vibration of the straps.

US Patent:

Filed:

Jul 29, 2015

Appl. No.:

14/812466

Inventors:

- Cranberry Township PA, US
Yong (Roger) Lu - Columbia SC, US

Assignee:

Westinghouse Electric Company LLC - Cranberry Township PA

International Classification:

G21C 3/34

Abstract:

A nuclear fuel assembly grid that includes two zones, a protected zone and a crumbled zone. The crumbled zone occupies the periphery of the grid and is designed to experience plastic deformation under high impact loads and the protected zone occupies the interior of the grid where the control rod guide thimbles are located and protects all of the control rod guide thimble locations by experiencing only plastic deformation under such loads.
