Polonium is the radioactive product of neutron activation of molten lead-bismuth, a promising candidate coolant for advanced fast nuclear reactors. The radiological hazard associated with polonium can be significantly reduced by continuous online removal of polonium from the coolant. The Japanese Nuclear Cycle Development Institute sponsored a three-year research effort to investigate two polonium separation mechanisms (alkaline extraction and electro deposition). Since there are no stable isotopes of polonium, tellurium was used as a surrogate while exploring separation mechanisms. This year, two experimental investigations occurred simultaneously: 1) alkaline extraction chemical kinetic measurements, and 2) design, construct, and perform electrode experiments. The modeling of the Te extraction experiment is completed with the measurement of rate constants, activation energy, and heat of reaction. The electro-deposition experiments were initiated and completed this year, with inconclusive results. Very little consistency was found and more research is needed to improve the amount of sample collected for analysis.

The acceleration method of laser plasma electron acceleration has very strong electric field, however, the acceleration length is veryshort. Hence, the energy gain of electron beams were confined to be approximately 100 MeV. Recently, this problem was solved by using discharge capillary. The feature of plasma was used that high dense plasma has low refractive index. Distributing plasma inside capillary as low dense plasma is in the center of capillary and high dense plasma is in the external side of capillary can make a laser pulse propaget inside capillary with initial focal spot size. Experiments with capillary were performed in China Academy of Engineering Physics (CAEP) and Japan Atomic Energy Agency (JAEA). We obtained the results of 4.4 J laser pulse optical guiding in 4 cm capillary and 0.56 GeV electron production in CAEP in 2006, and 1 J laser pulse optical guiding in 4 cm capillary and electron beams productions.
