Three of the four wells in the Grand Canyon region of the United States with average arsenic levels above the Environmental Protection Agency's safe drinking water standard are at a uranium mine site, according to a new analysis of groundwater sampling from Inside Climate News.

The contaminated wells are at the Pinyon Plain Mine, which sits within a national monument nine miles from the Grand Canyon's South Rim, Inside Climate News reported.

The study came from the Grand Canyon Trust and drew on 32 years of groundwater sampling across 40 sites monitored by the U.S. Geological Survey and the Arizona Department of Environmental Quality, according to Inside Climate News.

Activated metallic components produced during reactor operation, maintenance, and decommissioning rarely present a uniform packaging challenge, according to Power Magazine.

The International Atomic Energy Agency (IAEA) Nuclear Energy Ministerial Conference opened at Songdo Convensia in Incheon, South Korea, on Oct. 27, according to BusinessKorea. The venue was set up for high-level dialogue on peaceful uses of nuclear energy and technical cooperation.

More than 800 nuclear experts and government officials from 60 countries gathered in Songdo to discuss future energy policy, BusinessKorea reported.

The IAEA projects that global nuclear capacity could rise from 377 GW at the end of 2025 to between 641 GW and 1,045 GW by 2050 under its low and high case projections.

IAEA Director General Rafael Grossi urged countries to strengthen their institutions, protect existing capacity through long-term operation, bring financial and technical partners together early, and invest in training and suppliers.
