Abstract
A process for inhibiting corrosion caused by the presence of coolant water passing through a pressurized water nuclear reactor by the addition of an effective amount of an aqueous solution of zinc borate to the reactor coolant water. The transport of corrosion products and radioactive cobalt ions through the reactor primary circuit, as well as levels of radioactivity within the primary circuit, are reduced.
