The Tennessee Valley Authority is a federally owned corporation in the United States created by congressional charter in May 1933 to provide navigation, flood control, electricity generation, fertilizer manufacturing, and economic development in the Tennessee Valley, a region particularly affected by the Great Depression. The enterprise was a result of the efforts of Senator George W. Norris of Nebraska. TVA was envisioned not only as a provider, but also as a regional economic development agency that would use federal experts and electricity to rapidly modernize the region's economy and society.TVA's service area covers most of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small slices of Georgia, North Carolina, and Virginia. It was the first large regional planning agency of the federal government and remains the largest. Under the leadership of David Lilienthal , TVA became a model for America's governmental efforts to seek to assist in the modernization of agrarian societies in the developing world. Wikipedia.

Integrated Environmental Assessment and Management | Year: 2015

A baseline ecological risk assessment (BERA) was performed for residual ash in theWatts Bar Reservoir following a release of fly ash from the Tennessee Valley Authority (TVA) Kingston Fossil Plant. The site consists of parts of 3 rivers in eastern Tennessee comprising over 32 river kilometers. The purpose of the assessment was to determine if residual ash negatively impacts maintenance and reproduction of balanced communities or populations of potentially exposed ecological receptor groups in these rivers. This introductory article summarizes the site and environmental setting, assessment and measurement endpoints, risk characterization methods, and the study approach. Subsequent articles describe ecological risks to fish, benthic invertebrates, aquatic- and riparian-feeding wildlife, and aerial-feeding insectivores; and the role ecological risk characterization played in determining the most effective management of the residual ash, setting project remediation objectives and targets, and designing long-term monitoring to measure the effectiveness of the selected removal action. © 2014 SETAC.

Tennessee Valley Authority | Date: 2013-08-30

A solar photovoltaic panel system which has a thermal sink and a panel mounting structure is provided. The panel mounting structure contains a water flow section. The water flow section includes an inflow section and an outflow section. A solar photovoltaic panel is mounted between the inflow section and the outflow section. A water supply system is connected to the panel mounting structure to provide water on a top surface of the solar photovoltaic panel. The water provided from the thermal sink is returned to the thermal sink after flowing on the top surface of the solar photovoltaic panel.

« GM creates dedicated team to drive autonomous and advanced technology vehicle development | Main | Sandia segmented morphing rotor blade design could enable 50MW offshore wind turbines with 200-meter blades » Leading developers and potential customers of small modular reactors (SMR) have formed a consortium to advance the commercialization of the innovative reactor designs. The memorandum of understanding establishes an organization called SMR Start. The organization is designed to help accelerate the commercialization of SMRs by creating an industry-driven entity whereby potential reactor owners/operators would be a unified voice in a variety of policy and regulatory issues and in creating cost-share funding structures. Initial SMR Start members include BWX Technologies Inc.; Duke Energy; Energy Northwest; Holtec; NuScale; PSEG Nuclear; Southern Co.; SCANA; and Tennessee Valley Authority. The organization will represent these companies in interactions with the US Nuclear Regulatory Commission, Congress and the executive branch on small reactor issues. The Nuclear Energy Institute is assisting in the formation of SMR Start and will work closely with the organization on policies and priorities relating to small reactor technology. SMR Start will focus on light-water reactor based SMR designs and will serve as a demonstration to the public and private sectors of small reactor customers’ commitment to the market. Nuclear power plants supply around one-fifth of America’s electricity and nearly 63% of its carbon-free electricity. The Energy Information Administration forecasts an 18% growth in electricity demand by 2040. In light of this forecast and nuclear plant retirements, the US market will need more than 100 new nuclear plants by mid-century to maintain the benefits of a diverse electricity portfolio, according to the Nuclear Energy Institute (NEI).
