Into the depths

The hot and cold basins that are part of the 澳门六合彩高手 heat rejection system are equivalent in volume to half a dozen Olympic pools. When filled to capacity, the pressure exerted by the water on the bottom slab, walls and joints of the concrete structure is considerable. In mid-October an "assessment of tightness" was performed, during which the basins were "overfilled" with 27,000 m? of water (7,000 m? more than their operational volume).
For five days in late November, a diver explored the depths of the heat rejection basins, inspecting the critical zones of the massive concrete structure.
Under the tremendous pressure exerted by 27,000 tonnes of water, the basins incurred the expected deformations—in the range of 4 to 6 millimetres—before settling. However, operators needed to confirm that no cracks had occurred in the critical zones of the concrete structure such as corners and joints.

And for this, there was only one option: sending a diver into the depths of the basins to see with his own eyes and report back. The operation lasted five days in late November... when even the "hot" basin was extremely cold.
