Separation and Recovery Technology

Purpose: Efficient separation and recovery of long-lived Fission Products (LLFPs) Technologies

Current Results

Pd even / odd separation using polarized laser pulses

Purpose: Separation of odd nuclides from even ones by ionization of odd ones

Progress: an efficient odd / even separation scheme for palladium

  • Improved low-excitation / ionization yield with conventional circular polarization by a new efficient excitation scheme.
  • Confirmed an approximately 10,000 times higher ion yield than with conventional scheme.
