Title: Reactor control rod and method for manufacturing it
Inventor: KANO FUMIHISA
IPC: G21C7/10
Filed: 2008-04-09
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that the risk of irradiation assisted stress corrosion cracking (IASCC) becomes higher with long-term irradiation because conventional reactor control rods made of hafnium have stainless sheathes though hafnium as a neutron absorbing member has longer life than boron carbide.  <P>SOLUTION: Sheathes using a zirconium-based alloy are adopted. Zirconium is excellent in irradiation resistance because of its small neutron absorption cross section and can maintain a sufficient strength and corrosion resistance even if it is irradiated for a long period. Moreover, the similarity between physical properties other than the neutron absorption cross section of zirconium and those of hafnium can prevent thermal stress from appearing.  <P>COPYRIGHT: (C)2010,JPO&INPIT
