The uranium enrichment facilities at the Nuclear Fuel Cycle Engineering Laboratories of Japan Atomic Energy Agency (JAEA) were constructed sequentially to develop uranium enrichment technology with centrifugal separation method. The developed technologies were transferred to Japan Nuclear Fuel Limited until 2001. And the original purpose has been achieved. Wastewater Treatment Facility, one of the uranium enrichment facilities, was constructed in 1976 to treat radioactive liquid waste generated at the facilities, and it finished the role in 2008. In accordance with the Medium/Long-Term Management Plan of JAEA Facilities, interior equipment installed in this facility had been dismantled and removed since November 2021 to August 2023. This report summarizes the findings obtained through the work related to dismantling and removal of interior equipment for decommissioning of Wastewater Treatment Facility.

Phase equilibria in the Mn-Zn binary system were experimentally determined by chemical composition examination, crystal structure determination, and thermal analysis. Major changes were detected for the $$beta$$, $$varepsilon$$, and $$delta$$ phases. The $$beta$$-B2 single-phase region could not be confirmed in the studied system because a disordered body-centered cubic structure, which is identical to the $$delta$$Mn phase, was confirmed in a quenched sample from the previously proposed region of $$beta$$ phase. The $$varepsilon$$ phase has been controversial whether the phase is separated into $$varepsilon$$, $$varepsilon_{1}$$, and $$varepsilon_{2}$$ phases or not. By studying a diffusion couple and several alloy compositions, it was established that the $$varepsilon$$, $$varepsilon_{1}$$, and $$varepsilon_{2}$$ phases are not separate and comprise a single $$varepsilon$$ phase. Furthermore, the $$delta$$ phase is not present in the Zn-rich region of the system because the corresponding invariant reactions were not detected via thermal analysis.
