Oxygen suppression in boiling-water reactors: Phase 2. Final report
- comp.
An oxygen suppression demonstration was completed at the Dresden-2 plant of Commonwealth Edison Co. (CECo) during May and June 1982. The suppressing chemical additive was hydrogen gas dissolved in the reactor feedwater at concentrations from 0 to 1.8 parts per million (ppM). At full power oxygen in the primary coolant in the recirculation system was reduced to 15 parts per billion (ppB); oxygen in the steam was reduced to 3 ppM. Power level did not influence the effectiveness of oxygen suppression in the core exit water (steam), but had a profound effect on the oxygen concentration of the water entering the recirculation piping. Hydrogen addition caused slight, but real and repeatable increases in primary coolant conductivity and pH. Corrosion product concentrations in the feedwater decreased during the test.
