Chemical properties and behavior of insoluble residue in the cold cap of simulated high-level waste glass was examined by using synchrotron radiation based imaging and XAFS analyses. From XAFS analyses of Zr, Mo and Ce, (1) Zr is in a complex oxide like ZrSiO or Zr(MoO), (2) The complex MoO $^{2-}$ ion is predominant for Mo element, (3) Redox state for cerium element was evaluated from Ce L-edge XAFS, and (4) Chemical state of cerium was determined from Ce K-edge XAFS. Chemical state and bubble growth at molten state was investigated by using X-ray imaging analysis.
