摘要: A neutron absorbing pin including at least, a neutron absorber, a thin-wall pipe surrounding the neutron absorber, and a cladding disposed at a distance from the thin-wall pipe. In the neutron absorbing pin, the difference between the coefficient of thermal expansion (.alpha.1) of the neutron absorber and the coefficient of thermal expansion (.alpha.2) of the thin-wall pipe has an absolute value of .vertline..alpha.2-.alpha.1.vertline..ltoreq.10.times.10.sup.-6 /K.
