The plant has two Westinghouse pressurized water reactors. Sequoyah units 1 & 2, as well as their sister plant at Watts Bar, both have ice condenser containment systems. In case of a large loss-of-coolant accident, steam generated by the leak is directed toward borated ice which helps condense the steam creating a lower pressure, allowing for a smaller containment building.
The operating license of Sequoyah's Unit 1 expires in 2020. Unit 2's operating license expires in 2021.
TVA's Sequoyah operating license was modified in September 2002 to allow TVA to irradiate tritium-producing burnable absorber rods at Sequoyah for the U.S. Department of Energy. The process of irradiating tritium-producing rods produces tritium, which is used in nuclear weapons and for various forms of research into nuclear fusion for commercial power production.

NRC information on the License Extension - http://www.nrc.gov/reactors/operating/licensing/renewal/applications/sequoyah.html It is remarkable that there is no date on the cover or other substantial documents listed on the NRC site references listed on the link referenced.
The Sequoyah plant has two pressurized water reactors. The current operating licenses are due to expire Sept. 17, 2020, for Unit 1 and Sept. 15, 2021, for Unit 2. The operator, Tennessee Valley Authority, submitted its renewal application Jan. 15, 2013.
The NRC’s review of the application consists of a technical safety review and an environmental review. The draft supplemental environmental impact statement is Supplement 53 to NUREG-1437, Generic Environmental Impact Statement for License Renewal of Nuclear Plants. It is now available on the NRC’s electronic document database, ADAMS http://www.nrc.gov/reading-rm/ adams.html. under accession number ML14211A454.
In a related Federal Register notice, the NRC provided detailed instructions on how to submit written comments on the draft supplemental environmental impact statement. Comments will be accepted through Sept. 29, 2014 .Please refer to Docket ID NRC–2013–0037 Mail comments to: Cindy Bladey; Office of Administration, Mail Stop: 3WFN–06–A44M, U.S. Nuclear Regulatory Commission, Washington, DC 20555–0001.

BEST-MATRR's investigations into health, cancer and radiation in the Tennessee River Valley current summary: Government health statistics and scientific investigations point toward this fact - radiation from man made ionizing radiation sources such as nuclear power plants, nuclear fuel facilities, nuclear weapons facilities and nuclear experimental facilities have increased ionizing radiation levels in the environment within the Tennessee River Basin area. Since the addition of nuclear facilities in the Tennessee River Valley, the cancer incident rates and mortality rates have steadily increased. (National Cancer Institute statistics and maps http://seer.cancer.gov/statistics/scp.html and BEST/MATRR Report: http://best-matrr.org/pdfs/AL_BFN_Report_2013-final-dig2.pdf )" BEST-MATRR's investigations are ongoing in East Tennessee and North Alabama.
