Method Of Determining A Cell Friction Metric For A Control Cell Of A Nuclear Reactor

View page
US Patent:
20070177710, Aug 2, 2007
Filed:
Jan 27, 2006
Appl. No.:
11/340469
Inventors:
Atul Karve - Wilmington NC, US
Gerald Potts - Wilmington NC, US
Mark Dubecky - Wilmington NC, US
Robert Rand - Wilmington NC, US
Gerald Latter - Wilmington NC, US
Brian Moore - Wilmington NC, US
International Classification:
G21C 7/00
US Classification:
376327000
Abstract:
In a method of determining a cell friction metric for a control cell of a nuclear reactor, a channel face fast fluence and/or a channel face controlled operation parameter is determined for all channels. A total bow value is calculated for each channel based on the channel face fast fluence and/or channel face control parameters. For each channel, a channel wall pressure drop parameter is determined, and a total bulge value is calculated for each channel using the channel face fast fluence and channel wall pressure drop parameters. Total deformation at specified channel axial elevations for the cell is determined based on the total bow and bulge values. A control blade axial friction force value is calculated at each axial elevation based on the total deformation, along with channel stiffness and channel-control blade friction coefficient values. A maximum friction value is selected as the cell friction metric for the cell.

Composite Spacer With Inconel Grid And Zircaloy Band

View page
US Patent:
52098990, May 11, 1993
Filed:
Sep 4, 1991
Appl. No.:
7/754825
Inventors:
Eric B. Johansson - Wrightsville NC
Bruce Matzner - San Jose CA
Gerald M. Latter - San Jose CA
Assignee:
General Electric Company - San Jose CA
International Classification:
G21C 334
US Classification:
376442
Abstract:
An improved spacer is disclosed which contains an Inconel grid and a Zircaloy surrounding band. The Inconel grid can be fabricated from the extremely thin and highly elastic spring metal utilizing a modification of a prior art cell construction that includes paired inwardly bent vertical spring legs with cantilevered and rod encircling upper and lower arm pairs The spring legs extend at spaced apart locations between the upper and lower arm pairs and have a medial spring rod contacting portion for biasing the rods into stops on the rod encircling arm pairs. The springs at the upper and lower ends are provided with spring dimple stops to prevent over stressing of the spring during assembly or handling of the fuel bundle into which the spacer is incorporated. The rod encircling arm pairs have an offset from center where the two arms meet at their distal ends to complete encirclement of the rods. This offset from center enables the cells to be fastened in cell pairs at their respective embracing arms.

Lower Tie Plate Debris Catcher For A Nuclear Reactor

View page
US Patent:
54886341, Jan 30, 1996
Filed:
Feb 10, 1994
Appl. No.:
8/194357
Inventors:
Eric B. Johansson - Wrightsville Beach NC
Robert B. Elkins - San Jose CA
Bruce Matzner - San Jose CA
Gerald M. Latter - Wilmington NC
Richard A. Proebstle - San Jose CA
Assignee:
General Electric Company - Schenectady NY
International Classification:
G21C 1942
US Classification:
376313
Abstract:
A unitary one-piece lower tie plate grid has a lower portion and an upper portion for supporting the fuel rods. The lower tie plate grid includes cylindrical boss portions extending upwardly from the lower grid portion and arranged in square matrices for receiving the lower end plugs of the fuel rods. Web portions extending upwardly from the lower tie plate portion interconnect the boss portions along the sides of the matrices. The lower grid portion includes a plurality of openings which open into the flow spaces defined by the convex portions of the bosses and the webs within each square matrix of the upper portion of the tie plate. Coolant flows through the openings into the flow spaces for further flow upwardly about the fuel rods. The openings are radiussed adjacent their lower ends and have divergent side walls downstream of a throat area to define a flow venturi.

Handle Unit For A Fuel Assembly In A Nuclear Reactor And Fuel Assembly Having Modified Channel

View page
US Patent:
58091017, Sep 15, 1998
Filed:
May 29, 1996
Appl. No.:
8/655875
Inventors:
Thomas G. Dunlap - Wilmington NC
Gerald M. Latter - Wilmington NC
Mark J. Colby - Wilmington NC
Michael R. Stepp - Wilmington NC
Assignee:
General Electric Company - Schenectady NY
International Classification:
G21C 332
US Classification:
376446
Abstract:
A fuel bundle assembly for a nuclear reactor includes a modified channel and a handle unit that improves pressure drop performance. With the modified channel, one approach is to vary the outside dimension of the fuel channel along the length of the channel, but maintain a constant channel wall thickness. Another approach is to maintain the external dimensions of the fuel channel and vary the wall thickness along the length of the channel. The handle unit is formed including a handle member and a separate rod support member releasably engageable with the handle member. The handle member includes channels for receiving latch pin assemblies, coolant rods and a spacer assembly. The rod support member includes a plurality of fuel rod support chambers providing lateral support for the fuel rods of the fuel assembly. The rod support member also includes a main chamber that is sized to receive a portion of the handle member in a friction fit. In addition to providing improved pressure drop performance, the arrangement eliminates the need to realign the fuel rods in an upper tie plate or an upper spacer when access to the fuel rods is necessary.

Handle Assembly And Channel For A Nuclear Reactor Fuel Bundle Assembly

View page
US Patent:
57871400, Jul 28, 1998
Filed:
May 29, 1996
Appl. No.:
8/654957
Inventors:
Thomas G. Dunlap - Wilmington NC
Gerald M. Latter - Wilmington NC
Mark J. Colby - Wilmington NC
Michael R. Stepp - Wilmington NC
Assignee:
General Electric Company - Schenectady NY
International Classification:
G21C 332
US Classification:
376313
Abstract:
A fuel bundle assembly for a nuclear reactor includes a modified channel that improves pressure drop performance and a handle assembly that includes structure for preventing a broken end plug from escaping the fuel bundle. In modifying the channel, one approach is to vary the outside dimension of the fuel channel along the length of the channel, but maintain a constant channel wall thickness. Another approach is to maintain the external dimensions of the fuel channel and vary the wall thickness along the length of the channel. The handle assembly replaces the conventional upper tie plate and is provided with structure for preventing debris such as a broken fuel rod end plug from escaping the fuel bundle. The structure preferably includes a plurality of gridwork cross members forming a substantially square grid including gridwork windows that are sized smaller than the fuel rod end plugs.

Nuclear Fuel Assembly Spacer And Loop Spring With Enhanced Flexibility

View page
US Patent:
50858270, Feb 4, 1992
Filed:
Feb 6, 1991
Appl. No.:
7/652340
Inventors:
Eric B. Johansson - San Jose CA
Gerald M. Latter - San Jose CA
Michael V. Curulla - San Jose CA
Assignee:
General Electric Company - San Jose CA
International Classification:
G21C 332
US Classification:
376444
Abstract:
A spring-and-spacer assembly for maintaining fuel rods upright in a fuel assembly of a nuclear reactor core is provided. The spring is in the form of a continuous loop with first and second legs having mid-leg rod-contact regions. Bend regions are positioned on each side of each contact region extending toward the interior of the loop spring. In most positions, the spring is used to load two adjacent fuel rods. In configurations in which there is an unpaired fuel rod, a plate having a tab for contacting the spring is provided. The spring provides the desired force, such as about 2. 5 pounds per fuel rod, in a small rod-to-rod spacing of less than about 0. 14 inches.
