DOE announces awards for three university nuclear education outreach programs
The Department of Energy’s Office of Nuclear Energy has announced more than $590,000 in funding awards to help three universities enhance their outreach in nuclear energy education. The awards, which are part of the DOE Nuclear Energy University Program (NEUP) University Reactor Sharing and Outreach Program, are primarily designed to provide students in K-12, vocational schools, and colleges with access to university research reactors in order to increase awareness of nuclear science, engineering, and technology and to foster early interest in nuclear energy-related careers.

Ion Cyclotron Wall Conditioning (ICWC) has been performed in KSTAR. Fuel retention and removal, impurity removal have been investigated in a dedicated session. By varying pressure (mixture rate) and duty cycle, parameter study has been done. An average hydrogen retention rate of ~2 × 1020 H/sec is measured. The ratio of Himplanted/Dpumped is found to be ~5-15 depending on the operation conditions. Other impurity removal rate is of the order of ~1016-1017 molecules/sec. It is shown that inter-shot ICWC is a powerful tool for superconducting tokamaks like KSTAR and ITER.
