摘要

This project was initiated to develop a custom-designed online water analyzer (ion chromatograph) for secondary water chemistry control in TVA's nuclear plants. This water analyzer development was conducted pursuant to a cooperative research agreement with the Dionex Corporation. Dionex developed and installed a dual channel, six stream analyzer on the secondary side of TVA's Sequoyah Nuclear Plant. The analyzer was developed for real time detection of sodium, chloride, and sulfate in any of the six sampling streams. The analyzer is providing Sequoyah's plant personnel with reliable secondary water chemistry data in a much more timely manner than the past grab sampling techniques. Results on the performance of the analyzer show that it is performing above and beyond the expectations of plant personnel. Since its installation at Sequoyah, there have been 29 units ordered from Dionex including 1 unit for Sequoyah, 5 units for Browns Ferry, and 23 units for other utilities. In the future, the analyzer will allow plant staffs to take corrective action before corrosive conditions occur or before having to derate a unit. (ERA citation 11:050545)
