An optimal concentration of iron in the feedstream of a Boiling Water Reactor is important to GE Nuclear Energy in order to reduce radiation exposure to GE’s employees. Iron is currently being pumped in the form of an iron oxalate solution, but GE desires an alternative to the pump system. The Clinic team has been asked to design this alternate solution that provides manual control of the injection rate to maintain the iron concentration between 0.5 and 1.5 ppb mass and also provides process indicators.
