Final remediation could add spark to regional technology and alternative-energy industry

OAK RIDGE — Workers finished clearing more than a million tons of nuclear-contaminated soil from a long-toxic site in the Atomic City dating to the World War II and Cold War eras.

While the site was established to enriched uranium for the atomic bomb the U.S. dropped on Hiroshima toward the end of WWII, its future may lie in solar power and peaceful use of nuclear technology. The cleanup also ties into broader questions and controversies about storage of wastes from other Oak Ridge sites.

The U.S. Department of Energy’s (DOE) Oak Ridge Office of Environmental Management (OREM) and its contractor United Cleanup Oak Ridge (UCOR) removed and disposed of more than 554,000 cubic yards of soil, equaling nearly 50,000 dump truck loads, according to OREM.

“Today is a significant and meaningful step toward completing our ultimate mission at the East Tennessee Technology Park,” said OREM Manager Jay Mullis. “Our progress has transformed the site from an unusable liability into an economic asset for the Oak Ridge community.”

Public/private grants will fund natural resource preservation and enhancement in East Tennessee

OAK RIDGE — The U.S. Department of Energy signed a $42 million agreement as part of the Natural Resources Damage Assessment and Restoration (NRDAR) process for impacts from its historic operations on the Oak Ridge Reservation. 

Contamination released from the Oak Ridge Reservation negatively impacted natural resources and services depending on those resources in the region. The goal of the NRDAR process is to restore natural resources and replace natural resource services equivalent to what was lost. 

A trustee council comprised of representatives from the state of Tennessee through the Tennessee Department of Environment and Conservation (TDEC) as the lead state agency, U.S. Fish and Wildlife Service, Tennessee Valley Authority and DOE evaluated how natural resources were injured and developed a Restoration and Compensation Determination Plan. That document was finalized in December 2022 after accepting public comments.

All funds from the $42 million agreement will be deposited into an account held by the state to fund grants to organizations and public entities for a wide range of local projects that either enhance the area’s natural resources or provide nature and recreational opportunities.

OAK RIDGE — Caldera Holding, the owner and developer of Missouri’s Pea Ridge iron mine, has entered a nonexclusive research and development licensing agreement with Oak Ridge National Laboratory to apply a membrane solvent extraction technique, or MSX, developed by ORNL researchers to process mined ores. MSX provides a scalable, efficient way to separate rare earth elements, or REEs, from mixed mineral ores.

The MSX technology was pioneered at ORNL by researchers in the Department of Energy’s Critical Materials Innovation Hub, or CMI, led by Ames National Laboratory. The inventors, Ramesh Bhave and Syed Islam of ORNL’s Chemical Sciences Division are named in 26 inventions and five active licenses related to the recovery of REEs.

Volunteers nurture life in an Oak Ridge cemetery

OAK RIDGE — The northern corner here is a small place teeming with treasures, including the Worthington Cemetery Ecological Study Area.

Elza Gate Park off Oak Ridge Turnpike, also known as Tennessee Highway 95, is the starting point for walking trails taking visitors through a cedar barren, a somewhat open habitat including eastern red cedars. The barrens include plants more similar to a prairie than many East Tennessee forests. The trail reaches a cemetery dating before the founding of Oak Ridge.

Woven together in this small area there is a natural mix of wildlife and historical preservation. Visitors to the loop trail will encounter a pine forest and a wetland area complete with a boardwalk to observe birds. Tennessee Valley Authority designated the land as both an Ecological Study Area and Small Wild Area.

Thanks to an East Tennessee science powerhouse, recycling might become easier 

This is the first in a series about ORNL’s Technology Innovation Program 2023

OAK RIDGE — Researchers at Oak Ridge National Laboratory developed a catalyst they say can break down a range of plastics, including polyesters, polycarbonates, polyurethanes and polyamides through a low-energy green process. In lay terms, the process can recycle many plastic-based carpets, ropes, other textiles, bottles, mattresses, protective equipment, car components and other things that weren’t previously easy to recycle into valuable chemicals.

Tomoronori Saito, a researcher at ORNL’s chemical sciences division presented some results of research at ORNL on July 14 as part of a symposium highlighting commercially valuable work that takes place at one of the country’s main science laboratories. Saito and fellow researcher Arif Arifuzzaman showed off plastics in varying levels of disintegration using their catalyst. It was part of the lab’s Technology Innovation Program 2023, promoting the lab’s research for possible business partnerships.

OAK RIDGE — For the month of April 2023, the exhibition can bee seen, Thursdays and Fridays from 10 a.m. to 2 p.m. and Saturdays from 10 a.m. to 3 p.m., at the Oak Ridge History Museum, which is housed in the Midtown Community Center at 102 Robertsville Road, Oak Ridge, TN. That building itself is a significant landmark of Oak Ridge history. Constructed 1944-45, it has been used as a bathhouse and laundry, a hangout for students, a senior center, the Oak Ridge Convention & Visitors Bureau, and office of the Oak Ridge Heritage and Preservation Association. Many long-term Oak Ridgers refer to it simply as the ”Wildcat Den,” harking back to the time it was home base of the high school’s football team, the Oak Ridge Wildcats that were national champions in 1958.

NORRIS — The W. G. Lenoir Museum in Norris Dam State Park will be hosting “HerStory: A Photography Exhibition of Women in the Secret City.” The exhibit will open on March 1, and  be on display through the month in honor of Women’s History Month.

Constructed by the Civilian Conservation Corps (CCC) and opened in May 1936, Norris Dam State Park was managed by the Tennessee Valley Authority for 18 years prior to becoming a Tennessee State Park in 1953. Oak Ridge’s selection for the Manhattan Project was, in part, due to rural electrification that Norris Dam accomplished.

During the early 1940s, the park was closed to the public and the CCC vacation cottages winterized to house Manhattan Project workers. Later serving as a popular recreation destination for the growing government town, Norris Dam State Park continues to attract visitors from throughout the region. The construction of Norris Dam and Oak Ridge necessitated the relocation of countless families of the Clinch River valley by the federal government. These historical events connect these parks, and this new partnership will strive to tell the full stories of these places.

From janitors to homemakers and chemists, the women of the Manhattan Project worked hard and talked little. During WWII, Oak Ridge was a government town of 70,000 workers; primarily women who lived in a camp-like environment of barbed wire, security checkpoints, and code words. Workers were fingerprinted, interviewed, assigned a job, and given a clearance badge. Housing was limited and cramped and often unheated. Food at the cafeterias was in short supply and lines were long.   

The photographs were taken by James Edward Westcott, a renowned photographer who worked for the U.S. government in Oak Ridge during the Manhattan Project and the Cold War. Westcott was one of the few people permitted to have a camera in the Oak Ridge area during the Manhattan Project. For more information call the Manhattan Project National Historical Park at (865) 482-1942.

(From February 2022): Menacing military buildup on Ukraine borders and Orwellian denials could snuff peaceful scientific cooperation

OAK RIDGE — I went to Russia in 2000 on one of the most extraordinary trips of my life. It was a long time ago, and a generation has passed, but I was left with many enduring and positive impressions of the country and its people.

The newspaper I worked for, The Daily Times in Maryville, paid for my trip to Moscow, then to Siberia, (and back again, to my surprise) to cover a contingent of Blount County politicos/bureaucrats and Oak Ridge DOE types visiting a far eastern Russian town, Zheleznogorsk, that had long been home to both nuclear and chemical weapons processing facilities.

The goal, under the flag of Sister Cities, was ultimately geared toward introducing alternative commerce and industry to this forgotten town so the potentially catastrophic expertise would not be exported abroad. The temptation was surely there. These were people with advanced degrees who now lived in a place where a lot of people had never eaten in a restaurant.

Editor’s note: As reported in Hellbender Press, the Department of Energy’s Oak Ridge Office of Environmental Management (OREM) was reprimanded by the Southern Environmental Law Center for neglecting its duty to follow guidelines and proper procedures mandated by the National Environmental Policy Act (NEPA). Of immediate concern was OREM’s pretext and information — or specifically lack of pertinent information — released ahead of the public meeting on May 17, 2022 about its project for a new “Environmental Management Disposal Facility” (EMDF).

With regard to NEPA compliance, Oak Ridge Operations has been the black sheep in DOE’s stable because it never prepared the required site-wide environmental impact statement (EIS) for the Oak Ridge Reservation (ORR). At said public meeting, Virginia Dale, Corporate Fellow Emeritus of Oak Ridge National Laboratory, commented on another tangent of shortcomings — not spelled out by Federal law — but matters of common sense, competent decision making and good community spirit.

Public can comment in person Tuesday night in Oak Ridge on proposed DOE waste dump

OAK RIDGE — The Southern Environmental Law Center blistered the Department of Energy in a letter ahead of a May 17 hearing on construction of a toxic-waste landfill that opponents said poses contamination threats to portions of the Clinch River watershed and downstream TVA reservoirs.

The hearing is set for 6-8 p.m. Tuesday, May 17 at the Pollard Technology Conference Center, 210 Badger Ave. This email address is being protected from spambots. You need JavaScript enabled to view it. will be accepted through June 7.

The Department of Energy wants to bury contaminated debris from demolition of Manhattan Project-era complexes and associated legacy toxins from the Oak Ridge Reservation. The drawn-out debate about how best to safely store the materials now focuses on the transparency of the decision process and the health of the Bear Creek watershed and downstream pollution threats to the Clinch River. 

Knox News: Developer pulls Oak Ridge motorsports park proposal after pushback

In a victory for local environmentalists, the developer who proposed and pushed for a motorsports park on the western end of Oak Ridge has abandoned the project in hopes of finding a more “attractive” community.

The park would’ve been located in the Horizon Center industrial park and required the development of natural areas preserved via a city agreement with the Department of Energy.

Individuals and groups such as the Oak Ridge-based Tennessee Citizens for Wilderness Planning said the proposal was inherently inappropriate for the site, citing the loss of diverse, mature hardwood forest, and noise pollution.

Volunteers play the part of fire to maintain the native grasses and wildflowers at an Oak Ridge cedar barren

OAK RIDGE — It’s called a barren, but it’s not barren at all. It’s actually a natural Tennessee prairie, full of intricate, interlocking natural parts, from rocks and soil to plants and insects and animals.

There’s lots of life in these small remaining unique collections of grasses and conifers that are typically known, semi-colloquially, as cedar barrens. 

Many of these “barrens” have been buried beneath illegal dumping or asphalt, but remnants they are still tucked away here and there, including a small barren in Oak Ridge owned by the city and recognized by the state as a small natural area.
