Simple and rapid methods to evaluate the radioactivity concentrations are required for the radioactive waste generated from research facilities in the Japan Atomic Energy Agency to dispose of in a near-surface repository. In order to establish the methods to evaluate the radioactivity concentrations of miscellaneous solid waste generated from research and testing reactors, we collected and analyzed samples from miscellaneous solid waste generated by the decommissioning of JPDR (Japan Power Demonstration Reactor). In this report, we reported the analytical data determined in fiscal 2014 ($$^{137}$$Cs and $$^{93}$$Mo) and summarized them with the radioactivity concentrations obtained in the past as basic data to consider the evaluation method of radioactivity concentrations in the stored waste taken from JPDR.

A simple analytical method was developed for the determination of $$^{113m}$$Cd in the treated wastewater arising from Advanced Liquid Processing System (ALPS) at the Fukushima-1 Nuclear Power Plant. Cadmium in the wastewater containing sea salt was effectively purified by an anion-exchange procedure. It was found that more than 97% of Cd were recovered by the present procedure from a sample solution of 2M HCl. Since a radioactivity standard solution of $$^{113m}$$Cd was difficult to purchase from venders, beta-ray counting efficiency for $$^{113m}$$Cd was estimated using 99Tc and 36Cl standard solutions. Minimum detectable activity was calculated to be 0.003 Bq mL$$^{-1}$$. The present analytical method would be well suited for a rapid and simple determination of $$^{113m}$$Cd in wastewater treated by ALPS.
