The adulterating of food products for financial gain, either through dilution, substitution, mislabeling, or other action, has become a lucrative industry. And because food fraud is designed to avoid detection, gauging its financial impacts can be difficult to determine. Experts estimate that food fraud affects 1 percent of the global food industry at a cost of about $10 billion to $15 billion a year, with some estimates putting the cost as high as $40 billion a year, according to the U.S. Food and Drug Administration.

Savannah River Nuclear Solutions (SRNS), the management and operations contractor for the Department of Energy’s Savannah River Site, announced that it has injected more than 100 million gallons of clean artesian well water to neutralize shallow groundwater contamination underneath 33 acres of a former coal storage yard and the associated runoff basin at the site in South Carolina. According to Ashley Shull, senior scientist for the project, “100 million gallons is nine times more water than [is] contained in the Georgia Aquarium in Atlanta.”

Today’s nuclear power plants are the nation’s largest source of carbon-free energy, but they come with high operating and maintenance costs.

Competition from other sources, especially natural gas, coupled with low electricity prices, has resulted in the closure of some plants in the last decade due to economic reasons.

One way to alleviate these economic pressures is to reduce the cost of operating nuclear power plants, including the costs associated with physical security.

Nuclear new build procurement considerations

August 16, 2024, 3:02PMNuclear NewsMarc Tannenbaum

It may seem counterintuitive, but the best time to enhance the ability to support operations and maintenance for a new plant is before construction starts. This is one of many lessons learned by the currently operating nuclear fleet. As construction and startup of many nuclear facilities was completed, it quickly became evident that the ability to efficiently support operations and maintenance was limited. Most of the information necessary to establish and manage procurement of spare and replacement items, maintenance, and configuration of the facilities was unavailable and had to be gathered on a case-by-case, “on-demand” basis. Absence of necessary information and the associated challenges resulted in the need for staff augmentation and multiyear-long projects to develop equipment bills of material and maintenance programs and to perform technical evaluations for the huge quantities of spare and replacement items being requested.

The Department of Energy’s Office of Environmental Management has issued a final request for proposals for an infrastructure support services (ISS) contract at the department’s Paducah Site in Kentucky, which is the former home of the Paducah gaseous diffusion uranium enrichment plant. DOE-EM has conducted extensive cleanup and environmental remediation activities at the site since the late 1980s.

FirstEnergy agrees to $20 million settlement in Ohio bribery case

August 15, 2024, 3:00PMNuclear News

The State of Ohio and FirstEnergy reached a settlement this week to avoid prosecution in an ongoing corruption investigation involving the Davis-Besse and Perry nuclear plants.

In 2021, the U.S. Attorney’s Office for the Southern District of Ohio charged the energy company with conspiring “with public officials and other individuals and entities to pay millions of dollars to public officials in exchange for specific official action for FirstEnergy Corp.’s benefit.”

FirstEnergy will pay $19.5 million to the attorney general’s office within five business days and will pay $500,000 for an independent consultant to review and confirm unspecified “changes and remediation efforts” within the company. The company will also cooperate with investigators for two years or until the investigation, litigation, or prosecution is complete.

A facility at Argonne National Laboratory has been simulating nuclear reactor cooling systems under a wide range of conditions since the 1980s. Its latest task, described by Argonne in an August 13 news release, is testing the performance of passive safety systems for new reactor designs.

Designed as a half-scale model of a real reactor system, Argonne’s Natural Convection Shutdown Heat Removal Test Facility (NSTF) is used for large-scale experimental testing of the performance of passive safety systems, which are designed to remove decay heat using natural forces including gravity and heat convection. Those tests yield benchmarking data qualified to the level of National Quality Assurance-1 (NQA-1) that is shared with vendors and regulators to validate computational models and guide licensing of new reactors and components.

The first high-temperature, gas-cooled reactor ever built in the United States was Unit 1 at the Peach Bottom Atomic Power Station. This demonstration plant, located on the Susquehanna River approximately 80 miles southwest of Philadelphia, Pa., was tasked with validating HTGR design codes. It produced over 1.2 million megawatt-hours of electricity over 1,349 equivalent full-power days (EFPDs), which was distributed by the Philadelphia Electric Company.

QSA Global, Niowave to collaborate on Ac-225 production using Ra-226

August 14, 2024, 3:28PMNuclear News

QSA Global, a provider of radioisotope products, and Niowave, a Michigan-based producer of medical radioisotopes, announced that the companies will codevelop a scalable radium purification process using Niowave’s radium-226 processing technology to meet the demand for actinium-225, an alpha-emitter used in the treatment of cancer. According to the companies, the strategic partnership marks a significant advancement in the field of radiopharmaceutical technology, enhancing the supply chain for critical radioisotopes, including Ac-225.

Niowave uses a closed-loop cycle to produce high-purity Ac-225 and other alpha emitters from Ra-226 using a superconducting electron linear accelerator. According to the company’s website, the electron beam impinges on a photon converter to irradiate the Ra-226, inducing a photon-neutron reaction to Ra-225, which decays to Ac-225.
