The Central Disaster Management Headquarters (CDMHQ) stated on the 8th that it has chosen to remove Units 4 and 6 of the Ulsan Thermal Power Plant’s boiler towers, situated close to the location of the collapsed Unit 5, because of worries about possible further collapses. Previous rescue efforts encountered challenges, as significant machinery could not be brought near the towers due to fears of additional structural failures.

The CDMHQ stated that the choice to remove the towers was decided in a meeting that took place the day before at 11 PM, which involved members from the families of the victims.

Units 4 and 6, next to the collapsed Unit 5, have already completed most of their risk mitigation efforts—a procedure that includes cutting solid pillars and supports in advance to allow for regulated demolition. Unit 5 fell when its risk mitigation was 90% finished. Unit 4, situated roughly 30 meters apart, has finished 100% of this process, whereas Unit 6 is 75% complete.

During a meeting held by fire officials on the 8th, representatives stated, “Even powerful winds could present dangers to Units 4 and 6,” and they also mentioned, “The operation of big cranes could create significant vibrations, possibly leading to additional harm.”

Emergency crews are presently scanning the debris by physically cutting or clearing obstructions in the openings of the collapsed building, supported by sound detection devices and heat-sensitive cameras. Nevertheless, advancement is sluggish because of the intricate tangle of steel sheets and reinforcing bars at the location.

Officials, in collaboration with structural safety specialists, considered the options of removing or strengthening the remaining boiler towers before deciding on demolition. Immediate preparations for the controlled demolition started following the decision, with the work anticipated to take place around next week.

As per a report from the CDMHQ, “Taking down Units 4 and 6 is anticipated to speed up the rescue operations.”
