All reactors in Fukushima, Japan restore central control room lighting

All the reactors in Fukushima, Japan have restored the central control room lighting. It now appears that it still takes a certain amount of time to eliminate the accumulation of water in the turbine building of the first unit of the Fukushima** nuclear power plant, which also leads to the cooling of the atomic furnace. The system cannot be recovered for a long time. Although the current state of the atomic furnaces and spent fuel pools of several units is relatively stable, it is impossible to predict when some variables will occur. Text: Pack up    The nuclear leakage accident at the Fukushima** nuclear power plant in Japan is still ongoing. China Radio International’s Global Information program linked to Japan’s reporter Wang Yang and asked him to introduce the latest situation of the accident. The following is a detailed report. . Introduce the current status of the nuclear power plant. Now it seems that it still takes a certain amount of time to eliminate the accumulated water in the turbine building of the Fukushima ** nuclear power plant. This also causes the cooling system of the atomic furnace to be delayed. . Although the current state of the atomic furnaces and spent fuel pools of several units is relatively stable, it is impossible to predict when some variables will occur.   Currently, TEPCO’s approach is mainly to pump the accumulated water in the plant into a container called a water regenerator, which is a device that cools the steam released from the atomic furnace into water. The pumping operation of Unit No. has been started since No. 1, but after the pumping operation on Day No., the approximately centimeter-deep water in the plant has only dropped by about centimeters. I don’t know how much water is left. On the other hand, the water regenerator of Unit No. and Unit No. is already full of water, and the operation of pumping out the accumulated water cannot be started yet. The staff must first transfer the water in the rehydrator to other water tanks. This work has started yesterday, but it is estimated that it will take at least a lot of time.   In addition, there is better news that the central control room of the No. 1 reactor has been restored to light. So far, the lighting of the central control room of all the reactors has been restored, which will help improve the operating environment in the unit. On the other hand, some of the instruments of the No. 1 reactor have been connected to electricity, and the staff can grasp some conditions in the unit through the data displayed in the central control room.   . Have the Japanese government and relevant departments taken any new countermeasures against the current situation?   According to reports, in view of the current difficulties in power restoration in nuclear power plants, the Japanese government and Tokyo Electric Power Company are considering issuing large-scale plans to solve the current difficulties.  Relevant sources revealed that there are major countermeasures currently being considered by relevant departments. One is that in order to prevent the radioactive materials in the atomic furnace from continuously spreading out, a special paint will be used to seal the radioactive materials in the building, and then a special cloth will be used to cover several atomic furnaces caused by hydrogen explosions. The exposed factory building was covered. In order to prevent hydrogen explosions from happening again, they will install a filter with a ventilation device on the cover.   On the other hand, the accumulation of water in the turbine building has seriously hindered the restoration of power in the unit, so the pumping operation is also urgent. In addition, accumulated water containing a large amount of radioactive materials has been found in pipeline tunnels and shafts outside the building, and this accumulated water must flow into the sea. But the current difficulty is that there is no place to store this large amount of stagnant water. In this regard, the relevant departments have considered the practice of driving a large oil tanker near the nuclear power plant to act as a water tank.   In addition, the Japanese government is also considering cooperating with industry and the United States to use robots for field operations.  . Introduce the *new casualty figures. Has the reconstruction work begun?  According to the statistics of the Japanese National Police Agency, as of yesterday evening, the death toll caused by the earthquake and tsunami had risen to one person, and the number of missing persons reported to the police was one person. The number of evacuees in multiple evacuation centers in all prefectures is still as high as 10,000. However, in Fukushima Prefecture, affected by the nuclear accident, search and rescue work was almost impossible in some villages and towns close to the nuclear power station. At present, the Fukushima prefectural police confirmed the death toll as many people, but this number is expected to rise further.   With the gradual restoration of infrastructure in the disaster area, post-disaster rescue work has been relatively smooth. The Japanese government and local governments are stepping up to build simple houses for the victims, so that the victims can leave their lives in shelters as soon as possible. Before starting the reconstruction work, some of the hardest-hit areas have to face the work of cleaning up the rubble. It is understood that in Miyagi Prefecture, the amount of waste caused by the earthquake and tsunami will reach about 10,000 to 10,000 tons, which is equivalent to twice the annual garbage production in Miyagi Prefecture. Although the cost of cleaning up the ruins is fully borne by the state, it is expected that the entire cleaning up of the ruins will require years of practice. The governor of Miyagi Prefecture stated that he will strive to remove the destroyed houses and rubble first within one year. From this point of view, the reconstruction of the disaster area also takes a certain amount of time.
