In order to bring the situation under control the engineers pumped in liquid nitrogen to the core of the reactor to cool it down. Fire fighting material and sand were also useful in reducing the fire caused by graphite Construction of sarcophagus which was meant to hold the radioactive waste within began and its service has been quite useful only that it has some flaws in that it accumulates rain water which can cause corrosion to the structure.
