Dow Intros New Technology for PWR Nuclear Power Plants

Post date: Aug 13, 2013 8:24:48 AM

The Dow Chemical Company 's ( DOW ) business unit Dow Water & Process Solutions (DW&PS) has introduced a new technology - DOWEX MONOSPHERE 1400PC Cation Resin for Pressurized Water Reactor (PWR) nuclear power plants. The technology helps in enhancing plants' sustainability and reliability.

The new technology, which was launched at the 2013 Electrical Power Research Institute (EPRI), strengthens a plant's reliability by minimizing anion resin kinetic degradation related with the use of ethanolamine (ETA), which is further used to reduce flow-assisted corrosion (FAC) and iron transport within the secondary water systems.

DOWEX MONOSPHERE 1400PC Cation Resin is specially designed to address the problems related with ETA in condensate polishers. It delivers high-quality water to the steam generator for uninterrupted power production.

The trial test for DOWEX MONOSPHERE 1400PC Cation was conducted at Diablo Canyon Nuclear Power Plant in Avila Beach, Calif, which experienced rapid kinetic impairment of the anion resin.

The new tool provided by DOWEX MONOSPHERE 1400PC helps facilitate sustainable full flow condensate polisher operation. It can also be paired with the DOWEX MONOSPHERE 550A anion resin for use in PWR mixed bed condensate polishers.
