TEPCO starts full circulation cooling of reactors

By arevamirpal::laprimavera
2 July 2011 The whole process is as follows:

1. Take the highly contaminated water that has been stored in the Central Waste Processing Facility (about 120,000 tonnes of it) to the water treatment system;
2. The water first goes through the oil separating system built by Toshiba;
3. The water then goes to the system by Kurion, where different types of zeolite will remove 1) the oil/technetium, 2) cesium, and 3) iodine;
4. Then it goes to the system by AREVA, where it gets further decontaminated; if TEPCO decides so, the AREVA system can come before Kurion;
5. Then finally it goes to the desalination system built by Hitachi.
6. After desalination, the “treated” water is stored in a series of tanks;
7. The treated water is fed through the 10-centimeter diameter PVC pipes to the Reactor Pressure Vessels of the Reactors 1, 2, 3;
8. The water will leak through the RPVs and the Containment Vessels down to the reactor basements;
9. Again highly contaminated, the water then is routed from the basements of the Reactors 2 and 3 to the Central Waste Processing Facility;
10. Start at No.1 again.
