Half-plant zeta potential test, Interim report

PDF Version Also Available for Download.

Description

The production reactors operated by Douglas United Nuclear, Inc., use treated Columbia River water as the coolant on a once-through basis. Thus, radionuclides formed largely by the neutron activation of river salts are discharged to the river. One method of reducing the quantity of radionuclides in the effluent is to increase the efficiency of parent isotope removal during the coolant treatment process. It was recognized that an alum feed rate of 18 ppM is not necessarily optimum throughout the year. During certain periods it may be well in excess of requirements and overfeeding could be as detrimental to efficient parent ... continued below

Description

The production reactors operated by Douglas United Nuclear, Inc., use treated Columbia River water as the coolant on a once-through basis. Thus, radionuclides formed largely by the neutron activation of river salts are discharged to the river. One method of reducing the quantity of radionuclides in the effluent is to increase the efficiency of parent isotope removal during the coolant treatment process. It was recognized that an alum feed rate of 18 ppM is not necessarily optimum throughout the year. During certain periods it may be well in excess of requirements and overfeeding could be as detrimental to efficient parent isotope removal as underfeeding. Thus, a continuing effort has been underway to find a method for controlling alum feed rate to an optimum value. Flocculent feed rate control based on producing a constant value of the electrokinetic charge (zeta potential) of the floc has been practiced at some water treatment, plants. Although the hypothesis has not had universal acceptance in the water treatment field, laboratory and field data accumulated at Hanford indicated that further evaluation of the approach was warranted. In order to determine the effects of coagulant control based on zeta potential a half-reactor test was initiated at C Reactor on September 1, 1966. This report summarizes the results of the test.
