Martin Knoll is professor of geology and hydrology and chair of the Department of Earth and Environmental Systems at the University of the South. He will talk to the University of Tennessee Arboretum Society.

The program is at the UT Arboretum Auditorium at 901 South Illinois Avenue in Oak Ridge starting at 7 p.m. September 29. The talk is titled “Microplastics in the Tennessee, Cumberland, and Rhine Rivers: Why We Should Care.”

Knoll’s presentation will focus on his research investigating the concentration and types of microplastics found in the three rivers, a press release said. Special emphasis will be placed on his recent findings about the major sources of these microplastics and what might be done to reduce their numbers.

Disposing of uranium waste could cost at least $7.2 billion

The U.S. Department of Energy estimates it could cost at least $7.2 billion to convert and dispose of tens of thousands of cylinders of depleted uranium hexafluoride, a dangerous, corrosive waste byproduct of the uranium enrichment process. Some of the waste came from the former K-25 site in Oak Ridge and is now stored in Ohio, but a portion of the converted depleted uranium could eventually be returned to Oak Ridge for use in nuclear weapons.

The Y-12 National Security Complex flipped the switch on a new era as crews finalized the process of moving the entire site’s electrical supply to the new Pine Ridge substation.

In June, the Building 9204-02 (Beta 2) and Building 9201-01 (Alpha 1) electrical feeds were disconnected from the Elza-1 substation, marking the final load transition to Pine Ridge.

The new substation was built as one of seven Uranium Processing Facility Project subprojects. Designed and built by the Tennessee Valley Authority, Pine Ridge substation construction began in 2017 and was completed in 2020 at a cost of $60 million. The project team received the U.S. Department of Energy Secretary’s Project Management Achievement Award for finishing $13 million under budget and six months ahead of schedule. It is a 70-MVA (mega volt amp) facility and includes:

DOE picks Idaho for nuclear test reactor

Posted at

The U.S. Department of Energy has decided to build a nuclear test reactor at Idaho National Laboratory to study fuels and materials.

Besides INL, Oak Ridge National Laboratory had been considered as a potential site for the Versatile Test Reactor. ORNL remains one of five national laboratories that are partners on the project. DOE said building the test reactor at INL was its preferred alternative.

At ORNL, the Versatile Test Reactor would have been at a relatively undeveloped site previously considered for other projects about a mile east of the ORNL main campus. It would have required a new hot cell and a facility for post-irradiation examination and the conditioning of spent nuclear fuel for disposal. It would also have used existing facilities at ORNL, including the Irradiated Fuels Examination Laboratory and the Irradiated Material Examination and Testing Facility.

DOE said building the Versatile Test Reactor at either INL or ORNL would have small environmental consequences, but overall, the consequences would be less at the INL site. Among the reasons: A smaller area would be temporarily disturbed and permanently occupied at INL because of the need to build a new hot cell facility at ORNL. Unlike the INL site, the ORNL location abuts wetlands that would have to be managed or avoided under the Clean Water Act and Tennessee regulations. The removal of trees at ORNL would result in the loss of roosting habitat for sensitive bat species. And although small at both locations, the potential radiological impacts would be lower at INL because the Versatile Test Reactor would be farther from the site boundary and population density is lower near INL than ORNL.

U.S. Department of Energy public bus tours have resumed in Oak Ridge after a two-year pause due to the COVID-19 pandemic.

The tours began running again on July 11, and they are scheduled to continue through November.

“The program is a longtime staple in the community, helping educate residents and visitors about the site’s rich history and current missions,” DOE said in an EM Update newsletter published Tuesday. (EM stands for environmental management.)

The tour program started in 1996 and has attracted tens of thousands of visitors from all 50 states, DOE said.

The three-and-a-half-hour tours allow visitors to see all three DOE sites on the Oak Ridge Reservation, including Oak Ridge National Laboratory (ORNL), Y-12 National Security Complex, and East Tennessee Technology Park.
