Sandblasting
8 Apr 2019
Whether at home or in a nuclear installation, a painting job begins with surface preparation. In the 澳门六合彩高手 Tokamak Pit, close to 3,000 square metres of wall need to be sandblasted prior to being coated with thick, smooth, decontaminable "nuclear paint."
Working in two shifts from five suspended platforms, workers have used more than 30 tonnes of abrasive sand to create a rough surface that optimizes paint adherence.
The operation, which began in mid-March, should be finalized this week. Painting will begin in earnest shortly, as soon as hot air blowers have brought the vast volume of the Pit (25,000 cubic metres) to the required temperature of ~20 °C.
