Abstract

A 30-day test was conducted in the Integrated Chemical Effects Test (ICET) project test apparatus. The test simulated the chemical environment present inside a pressurized water reactor containment water pool after a loss-of-coolant-accident. The initial chemical environment contained 14.54 kg of boric acid and 0.663 g of lithium hydroxide (LiOH). Trisodium phosphate (3.786 kg), hydrochloric acid (211 mL), and additional boric acid (600 g) were added beginning
at 30 minutes and lasting until 4 hours into the test. The test was conducted for 30 days at a constant temperature of 60°C (140°F). The materials tested within this environment included representative amounts of submerged and unsubmerged aluminum, copper, concrete, zinc, carbon steel, and insulation samples. Representative amounts of concrete dust and latent debris were also added to the test solution. Water was circulated through the bottom portion of the test chamber during the entire test to achieve representative flow rates over the submerged specimens. The test solution reached a pH of 7.3, and the test solution turbidity steadied out at approximately 1 NTU after 5 days. No precipitates were observed in the solution, but large amounts of white deposits (nominally 0.125 to 0.250 in. in diameter) were observed on the submerged galvanized steel, aluminum, and inorganic zinc, coated steel coupons. The test solution remained clearly Newtonian for the entire test. Aluminum was not detectable in the solution. Calcium, magnesium, silica, and sodium were prevalent in the solution.
