ABSTRACT:
A passive method of adjusting the pH of the liquid used to flood the containment structure of a nuclear reactor following an accident such as loss of primary or secondary coolant. Perforated containers or baskets, which contain a pH adjusting chemical which is soluble in the flooding liquid (usually a slightly acidic solution of borated water) and which are covered or encapsulated with a plastic protective material, which is like soluble in the flooding liquid, are located in the emergency containment sumps.
