Neutron-absorbing material used for absorber shaft elements of fuel cooling installations for consumed radioactive fuel elements comprises glass or glass ceramic matrix containing neutron-absorbing element with reinforcing fibers
Neutron-absorbing material used for absorber shaft elements of fuel cooling installations for consumed radioactive fuel elements comprises glass or glass ceramic matrix containing neutron-absorbing element with reinforcing fibers
A neutron-absorbing material comprises a glass or glass ceramic matrix containing a neutron-absorbing element with 5-60 wt.% embedded reinforcing fibers. Preferred Features: The reinforcing fibers are present in an amount of 20-45 wt.%. The glass matrix is made from borosilicate glass, gadolinium-containing glass., aluminosilicate glass or alkali-alkaline earth silicate glass. The glass ceramic matrix is based on borate glass containing Li2O, Al2O3 and SiO2 crystals.
