The U.S. Nuclear Regulatory Commission has issued a final environmental impact statement, and the staff has recommended, based upon the environmental review, issuing an early site permit for the Clinch River Nuclear Site in west Oak Ridge, where two or more small modular nuclear reactors could be built.

The final environmental impact statement, or EIS, was issued by the NRC on April 3. A notice of the EIS and the staff’s recommendation was published in the Federal Register on Monday, April 8.

Committee recommends approving early site permit for Clinch River Nuclear Site

Posted at 1:40 pm April 2, 2019

A federal safety committee has recommended that an early site permit be approved for small modular reactors at the Clinch River Nuclear Site in west Oak Ridge.

The Advisory Committee on Reactor Safeguards recommended the approval in a January 9 letter to the U.S. Nuclear Regulatory Commission. The letter was signed by Michael L. Corradini, committee chair. The Advisory Committee on Reactor Safeguards reports on the parts of an early site permit application that concern safety. The committee’s recommendation does not appear to have been previously reported.

An early site permit evaluates the suitability of a site for the potential construction and operation of a nuclear power plant. The permit application for two or more small modular reactors at the 935-acre Clinch River site was submitted by the Tennessee Valley Authority in May 2016. TVA said the reactors could generate up to 800 megawatts of electricity.

In a presentation to the Advisory Committee on December 6, TVA outlined what it appears to consider advantages of the Clinch River Nuclear Site: access to 500 kilovolt and 161 kilovolt transmission lines; being a neighbor to the U.S. Department of Energy, an interested customer; strong community support; and access to basic infrastructure and an abundant and skilled workforce. Also, TVA owns and controls the site, the public utility said in a presentation by Dan Stout, director of nuclear technology and innovation. [Read more…]

Community meeting to discuss Bull Run closure on Tuesday

There will be a community meeting in Claxton on Tuesday evening to discuss the closure of the Bull Run Fossil Plant. The Tennessee Valley Authority board of directors agreed in February to close the coal-burning plant by 2023.

The meeting is scheduled from 6-8 p.m. Tuesday, April 2, in the Claxton Community Center at 1071 Edgemoor Road. It will include Statewide Organizing for Community eMpowerment (SOCM) and nonprofit partners, a press release said.

“The meeting’s purpose is to give concerned residents of the community around TVA’s Bull Run Fossil Plant an opportunity to connect and to share their concerns, hopes, and questions around TVA’s recent decision to retire the Bull Run coal plant by 2023 or sooner,” the press release said. “Now is the time to begin a dialog to protect our community’s common interests.”

Organizers said they are urging environmental engineers, scientists, community leaders, officials from Anderson County, the cities of Oak Ridge and Clinton, Tennessee Department of Environment and Conservation, and others to be available to share information and expertise, provide support, and address residents’ questions on coal ash, air pollution, health, worker transition, economic impacts, safe demolition and site reclamation, future site use, and property values.

TVA to lower level of Melton Hill Reservoir for annual shoreline maintenance

Posted at 9:07 am March 19, 2019
By Oak Ridge Today Staff Leave a Comment

The Tennessee Valley Authority will temporarily lower the water level of Melton Hill Reservoir from Sunday, March 24, through Sunday, April 7, to allow property owners to repair docks, stabilize shoreline, and pick up litter, a press release said.

The reservoir’s water level will be held between 790 and 792 feet above sea level—about two to four feet below its current level—during this period, the press release said. The exact rate of the drawdown will depend on weather conditions and may vary with rainfall amounts. Melton Hill will be returned to its normal winter elevation of 794 feet by April 7.

“As in the past, the drawdown targets and dates are subject to change due to weather constraints,” the press release said. “Recent heavy rains could result in greater than usual debris and erosion in some areas.” [Read more…]

TVA releases draft power generation plan

Posted at 11:19 am February 20, 2019
By John Huotari Leave a Comment

The Tennessee Valley Authority has released a draft version of a plan that evaluates its options to meet its power generation needs during the next 20 years, and it is accepting public comments.

Under development since early 2018, the draft of the Integrated Resource Plan was released for public review on Friday.

The Integrated Resource Plan is a power planning roadmap, TVA said in a press release Wednesday. It examines a variety of economic, regulatory, and market-driven scenarios and strategies—both within and outside TVA’s control—to help the public utility respond to changing energy demands while continuing to provide reliable power at the lowest possible cost, the press release said.

“The 2019 IRP emphasizes the importance of flexibility in our generation in response to the changing energy marketplace,” said Laura Campbell, TVA vice president of enterprise planning. “TVA looked at a wide range of possible futures, and flexibility is important in every case to ensure a reliable power supply.” [Read more…]

(For members) Retiring Bull Run, Paradise could save millions, more than $1 billion in ‘lifetime costs’

Posted at 1:49 pm February 18, 2019

The coal-burning Bull Run Fossil Plant in Claxton and Paradise Fossil Plant Unit 3 in Kentucky are not economical to operate, and retiring them will offer a savings of about $320 million and avoid more than $1 billion in capital costs, the Tennessee Valley Authority said Thursday.

The TVA Board of Directors voted 6-1 to close Paradise Unit 3 and unanimously agreed to close Bull Run during a meeting in Chattanooga on Thursday. Paradise could close by December 2020, and Bull Run is expected to close by December 2023.

The Bull Run and Paradise closures will be the first 1,700 megawatts of coal plant retirements of the 2,600 megawatts that could be retired through 2033 under a 2015 integrated resource plan, TVA President and Chief Executive Officer Bill Johnson told the board.

The Tennessee Valley Authority Board of Directors unanimously agreed Thursday morning to close the Bull Run Fossil Plant, a coal-burning power plant in Claxton.

The single-generator plant is across the Clinch River from east Oak Ridge.

In another plant retirement, the board voted 6-1 Thursday to close the one coal-fired generator still operating, Unit 3, at the Paradise Fossil Plant near Drakesboro, Kentucky.

The vote on Paradise was 6-1 on Thursday, with board member Kenneth Allen dissenting.

Paradise Unit 3 could be retired in December 2020, and Bull Run could be closed December 2023, TVA said. Bull Run has been reported to be running at about 30 percent capacity for several years. [Read more…]

(For members) NRC finds no significant impact from producing tritium at Watts Bar 2

Posted at 12:12 pm February 13, 2019

The U.S. Nuclear Regulatory Commission announced on Monday that there would be no significant impact from producing tritium for nuclear weapons in a second unit at the Watts Bar Nuclear Power Plant in Rhea County.

The project involves the Y-12 National Security Complex in Oak Ridge.

The tritium could be produced in Unit 2 at Watts Bar, which is near Spring City about 45 miles southwest of Oak Ridge.

Tritium, which boosts the yields of nuclear weapons, is already being produced in Watts Bar Unit 1. The Tennessee Valley Authority has been producing tritium there since 2003.

A record amount of rain has fallen in the Tennessee River Valley in 2018, and the year isn’t over yet. The rain might not be either.

The previous record of 65.1 inches of rain was set in 1973. The record, based on 129 years of weather data, was announced by the Tennessee Valley Authority on Friday.

“As 2018 draws to a close, yearly rainfall totals for the TVA region continue to climb to near record levels, and the trend for above average rainfall totals continues right up to year’s end,” the public utility said.

“For the week before Christmas, rainfall averaged two inches in the eastern Valley and 1.4 inches in the western Valley,” said James Everett, senior manager for TVA’s River Forecast Center. “We began spilling and sluicing at several locations the day after Christmas to increase flows and increase flood storage capacity, and that will likely continue into the New Year.” [Read more…]

The earthquake near Decatur early Wednesday morning was felt in Oak Ridge, according to social media reports. Oak Ridge Today readers reported feeling the earthquake in other communities such as Clinton, Hardin Valley, Harriman, Oliver Springs, Sevier County, and Atlanta.

The 4.4 magnitude earthquake was also felt in other areas across the Southeast, including in Tennessee, Georgia, and North Carolina.

Some people in the region described it as like a train or truck driving by, and they said homes shook, and doors and windows rattled. Some said it woke them up, and others said they didn’t feel it. (Oak Ridge Today did not feel it.)

The earthquake was reported about nine kilometers underground at 4:14 a.m., according to the U.S. Geological Survey. The epicenter was 11 kilometers north-northeast of Decatur. Oak Ridge is about 45 miles northeast of Decatur.

It was reported to be the largest in Tennessee since a 4.7 magnitude earthquake in Maryville in 1973 and the second strongest on record in East Tennessee. The Maryville earthquake 45 years ago was the strongest in East Tennessee. [Read more…]
