TVA Containment Pond Bursts, Causing Massive Coal Ash Flood
Just after midnight on Dec. 22, 2008, a 40-acre pond holding coal combustion waste for a Tennessee Valley Authority (TVA) steam power plant ruptured, sending a wave of wet ash across 300 acres of rural land in Harriman County, Tenn. It was the largest coal slurry spill in U.S. history — more than three times the size of the Martin Country, Ky., sludge spill of 2000, and about eight times that of the 1972 Buffalo Creek flood in West Virginia. Unlike that flood, which killed 125 people and injured scores others, this one, Tennessee authorities reported, resulted in no serious injuries or hospitalizations.

Exelon Drops ESBWR for Victoria Plant, Weighs Options
A year after Exelon Nuclear ceremoniously announced the selection of General Electric-Hitachi’s Economic & Simplified Boiling Water Reactor (ESBWR) design (Figure 2) as its preferred technology for a proposed two-unit nuclear facility in Victoria County, Texas, the operator of the largest nuclear power fleet in the U.S. — and the third-largest in the world — said it had reconsidered its decision. The company said it is now negotiating separately with Toshiba and GE-Hitachi, both vendors of the Advanced Boiling Water Reactor (ABWR), and with Mitsubishi Heavy Industries for its U.S. Advanced Pressurized Water Reactor (US APWR).

Eastern Europe Prepares for Nuclear Revival
Despite hostilities that linger as a result of the 1986 nuclear nightmare at Chernobyl, Ukraine, and pressure from the European Union to shut down older-generation plants, Eastern European countries from the Baltic to Bulgaria are renovating existing nuclear plants or building new ones. If these projects become reality, the region will be able to secure its power supplies as well as cover the ongoing shortages in countries such as Greece, Macedonia, and Albania.
