IAEA Urges Patience For Fukushima Nuclear Cleanup
February 8th, 2019
“Despite these achievements, many challenges remain to be tackled in the decommissioning process, and ensuring safety in this complex situation requires sustained daily attention.” The new report follows up on original analysis presented to Japanese authorities in November and finds that the “risk reduction strategy is being implemented at a pace commensurate with the challenges of the site-specific situation.” That being said, however, “the IAEA Review Team continues to identify water management as critical to the sustainability of decommissioning activities” and has urged for a decision for the disposition of contaminated water to “be taken urgently engaging all stakeholders.” Specifically, the IAEA Review Team determined that it is necessary to determine an end-game for the Advanced Liquid Processing System (ALPS) sooner rather than later, considering that “the volume of ALPS treated water [is] expected to reach the planned tank capacity of 1.37 million [metres-cubed] within the coming three to four years, and considering current site facility plan for space allocations, and that further treatment and control of the stored water before disposition would be needed for implementation of any of the five solutions considered by the Japanese Government.” (For more on TEPCO’s contaminated water treatment, see here.) Further, but regarding the retrieval and end-game of radioactive fuel debris, the report’s authors state that “there should be a clear implementation plan defined to safely manage the retrieved material” and that “TEPCO should ensure that appropriate containers and storage capacity are available before starting the fuel debris retrieval.” There is therefore need for immediate decisionmaking but long-term patience and goals in place to thoroughly address the large amount of radioactive and contaminated waste.
