A lack of rainfall is hitting the power industry especially hard in parts of Brazil. According to the U.S. Energy Information Administration (EIA), the country depends on hydroelectricity for more than 75% of its electric power supply (Figure 2). But with reservoir levels at historic lows in some places, more electricity has been required from […]

The Electric Power Research Institute (EPRI) has teamed with Purolite Corp. to begin the commercial manufacture of a new resin for removing radioactive elements from the internal water streams of nuclear power plants. The resin, called CoSeq, increases the amount and efficiency of cobalt (Co) removal compared to conventional resins. In-plant demonstrations have shown that […]
