Winn & Coales also reports that as part of a periodic safety review by British Energy it was decided to build a new seismically qualified standby water storage tank at their Teesside-Hartlepool Nuclear Power Station. With a capacity of more than 1,600m3, its purpose would be to help cool the reactor in the unlikely event of an earthquake in the area.
An earlier water storage tank had been coated with a coaltar-based paint, but after six years British Energy maintenance engineers found it "less than desirable". Following research on a number of available coatings, they chose Winn & Coales Archco-Rigidon 423D coating. Formulated from a glass flake filled vinyl ester resin, it has been specially developed to give long life protection in corrosive environments.
The main contractors for the design of the new storage tank and the cooling system were Thermal Engineering International. Sub-contractors McDonalds Engineering built the tank and applied the Archco-Rigidon 423D coating.
