【 摘 要 】

A process monitor is needed by British Nuclear Fuels Limited, Inc. (BNFL Inc.) to measure total {sup 99}Tc levels in column effluents during technetium removal from the aqueous fraction of the Hanford high-level tank wastes. The monitor must achieve detection limits of 1 x 10{sup {minus}8}Ci/mL (0.6 {micro}g/mL). Measurements must be done in near real time, with an analysis frequency of {approximately}15 min. The monitoring technology must be sufficiently simple and robust for unattended continuous operation in the plant settings.
