Patent Number: 
Section: claims

1. A neutron absorber system for a cell of a nuclear fuel storage rack, comprising: a neutron absorber having a first longitudinal portion and a second longitudinal portion, said first longitudinal portion and said second longitudinal portion having an angle therebetween greater than an angle between adjacent cell walls of the cell of the nuclear fuel storage rack, said first longitudinal portion and said second longitudinal portion being elastically deformable toward each other in response to a stress being placed thereon;  an installation tool configured to provide the stress to the neutron absorber to elastically deform said first longitudinal portion and said second longitudinal portion;  said installation tool configured to insert said neutron absorber into the nuclear fuel storage rack; and  said installation tool configured to release the stress on the neutron absorber  said first longitudinal portion and said second longitudinal portion configured to abut the adjacent walls of the cell in response to the release of the stress to cause a frictional fit between the first longitudinal portion and the second longitudinal portion and the adjacent walls of the cell to attach the neutron absorber to the adjacent walls of the cell of the nuclear fuel storage rack. 2. The system of  claim 1  wherein said neutron absorber comprises a chevron shape. claim 1 3. The system of  claim 1  wherein the cell angle is about ninety degrees. claim 1 4. The system of  claim 1  wherein the cell walls are vertical walls of the nuclear fuel storage rack. claim 1 5. The system of  claim 1  wherein said neutron absorber further comprises a plurality of notches configured to engage said installation tool. claim 1 6. The system of  claim 1  wherein said plurality of notches is configured to receive the stress from said installation tool to cause the elastically deforming of the first longitudinal portion and the second longitudinal portion. claim 1 7. The system of  claim 5  wherein at least one of said plurality of notches is cooperatively engageable with the plurality of cell walls. claim 5
