TEPCO plans on spraying a chemical hardening agent around the damaged Fukushima Daiichi nuclear plant to prevent the spread of radioactive dust and soil.
TEPCO says it will begin spraying the polymer emulsion on top of debris near the plant’s reactor buildings starting on Tuesday next week. This step is part of the plan announced by TEPCO on Sunday to stop the leaking radiation and bring the plant under control within the next 3 months. TEPCO says it hopes to finish spraying the agent around the reactor buildings by the end of May, and in the rest of the compound by the end of June.
They have been test spraying the chemical hardening agent since April 1st. To prevent dust around a common spent fuel storage pool from scattering, TEPCO began test coating it with an emulsion widely used in construction sites to settle dust.
Multiple explosions blew off the roofs and walls of the buildings housing the No. 1 and No. 3 reactors spreading radioactive dust all over the site. TEPCO says the polymer has hardened the debris and that radiation levels in the plant’s compound have remained relatively low.
