I REFER to the article 'Daya Bay battles brash ants' (South China Morning Post, November 10), about the problem of 'white ants' at Daya Bay.
We can confirm that there are no termites (or white ants) in the main plant and equipment of Daya Bay, as steel and metallic materials rather than wood are found in these locations.
There is, therefore, no 'safety threat' nor is the operation of the plant affected in anyway by termites.
Electric cables which may be potential targets of termites were specially treated by anti-termite chemicals at the manufacturer's plant before being imported to Daya Bay as a preventive measure.
Again, no termites are found in the many metres of cables at Daya Bay.
To make sure that the plant is free from termites, two dedicated inspectors go around to patrol the site on a daily basis and a contractor is hired to stem out termites and other insects that are sighted.
Occasionally in the past, a small amount of termites have been found in areas such as living quarters outside the main plant, but the problem was well under control and had no impact on the plant.
