We provide products and services to help nuclear plants prepare for external events, address extended station blackout conditions, provide enhanced spent fuel pool protection and mitigate a severe accident. We built safety into the design of our AP1000 plant, which harnesses natural forces like gravity, convection and condensation to achieve passive safety system shutdown. During a station blackout, or loss of all electrical power, the AP1000 plant’s passive safety system shuts down the reactor automatically, with no need for human intervention for up to 72 hours. Safety is at the forefront of our plants’ operations — Westinghouse is committed to helping provide safe, clean and reliable electricity.

The Oxamine system from Buckman is a safer alternative to gaseous chlorine, and it is more effective in an environment where ammonia is present. It provides better performance in high-demand systems, resulting in improved condenser cleanliness. Oxamine is more effective than chlorine on biofilm control while lowering corrosion rates on common system metal- lurgies. It is 100% mineral and produces no organic toxins, making it the greenest technology on the market. To learn more, contact your local Buckman represen- tative or visit us online at buckman.com.
