2320-499: The pumping was stopped. The accidental release was reported to the Mississippi Health Department and the NRC. As of the dates of the news reports, it was unknown both how much tritium had entered the river and how the tritium had collected in the standing water, given that Unit 2 was not an operational reactor and had never been completed. It is unknown how much tritium entered the river because samples were not taken at

2378-499: The remainder of the transmission organization , which reduces flow of cheaper electricity into the area. With a integrated power utility business model, Entergy makes money by constructing power plants, reducing the company's incentive to build transmission connecting it to other regions.

2784-779: The state would have easy communication. Couch demonstrated the radio in November 1921 to the Pine Bluff Rotary Club. WOK, "Workers of Kilowatts", went live the night of 18 February 1922. Immediately, AP&L started promoting WOK, and acquired more broadcasting equipment. There were no commercials on the station; it was fully supported by the utility company. In coming months, the station had many firsts in Arkansas: first broadcast sermon, first broadcast sports event, first broadcast music concert, first remote church broadcast. Couch extolled WOK (and radio in general) for "bringing all parts of

2842-486: The use of the current Entergy logo, each subsidiary had its own distinctive logo.

Louisiana Power and Light Company, for example (today's Entergy Louisiana) used the logo shown at right extensively from about 1967 to 1989, on buildings equipment, and advertising. Each of Middle South Utilities' subsidiaries used similar-styled logos Entergy's service territory includes

2900-595: The utility companies were in decline, and only provided night-time service. Couch proposed a partnership with Arkansas Land & Lumber Company, a large sawmill operation in Malvern, whereby sawdust and waste material purchased from the sawmill would be used to fuel boilers, producing steam for two 550-kilowatt turbines to generate electric power . The new system, a predecessor of Arkansas Power and Light Company (AP&L), became operational on 18 December 1914, providing Malvern and Arkadelphia with 24-hour electric service for

2958-568: The winter of 1932–33. One of the United States New Deal programs was the creation of the Public Works Administration in 1933, which was a magnification of Couch's public works sector inside the RFC.

Mississippi Power and Light, Louisiana Power and Light, New Orleans Public Service and Arkansas Power and Light were deemed to be an integrated system, and were reorganized under

3248-872: Was in excess of $ 25,000 per year. Inexpensive energy produced by these new projects helped lure several major industrial plants to Arkansas. Pine Bluff received the state's first textile mill, the International Paper Co. opened a paper mill in Camden , and other companies followed. In the 1920s, Couch had set his sights on buying electric companies in other states. In 1923, he merged four independent companies in Mississippi into Mississippi Power and Light. Two years later, he formed Louisiana Power and Light, which provided power to his Mississippi customers from northern Louisiana's natural gas fields. Meanwhile, in 1922, Sidney Mitchel of Electric Bond and Share Company (EBASCO),
