Nuclear power generation

FILE - In this March 22, 2019 file photo, the construction site of Vogtle Units 4 at the Alvin W. Vogtle Electric Generating Plant is seen, Friday, March 22, 2019 in Waynesboro, Ga. It’s not just cutbacks in nuclear plant inspections. Nuclear plant regulators are planning fewer mock commando raids to test plant defenses against terrorist attacks and are considering minimizing some safety warning, part of the rollbacks sought by the industry and gaining traction under President Donald Trump.

FILE - In this April 9, 2018 file photo, released by an official website of the office of the Iranian Presidency, President Hassan Rouhani listens to explanations on new nuclear achievements at a ceremony to mark "National Nuclear Day," in Tehran, Iran. As Iran prepares to break through limits set by its 2015 nuclear deal with world powers, each step narrows the time its leaders would need to have enough highly enriched uranium for an atomic bomb -- if they chose to build one. By Thursday, June 27, 2019, Iran says it will have over 300 kilograms of low-enriched uranium in its possession, which would mean it had broken out of the atomic accord.

FILE - This Sept. 13, 2012, file photo shows the San Onofre nuclear power plant along the Pacific Ocean coastline in San Onofre, Calif. Southern California's San Onofre nuclear power plant was permanently closed in 2013, but the site remains home to 3.5 million pounds of nuclear waste that has nowhere else to go. Members of a House subcommittee held a hearing Friday, June 7, 2019, not far from the defunct plant to highlight the urgency behind efforts to build a long-term national repository for used radioactive fuel, a proposal that has languished for decades in Washington.

FILE - In this Nov. 12, 2011, file photo, the Unit 4 reactor building of the crippled Fukushima Dai-ichi nuclear power station is seen through a bus window in Okuma, Japan. Japan is calling for further efforts to cut carbon emissions by promoting renewables but also nuclear energy despite the 2011 Fukushima reactors meltdowns, according to the energy white paper, adopted by the Cabinet Friday, June 7, 2019.

In this April 29, 2019 photo, a mildly contaminated transfer container stands wrapped and labeled as part of the decommissioning process at the Vermont Yankee Nuclear Power Station in Vernon, Vt. In January, privately held NorthStar Group Services completed the purchase of Vermont Yankee from New Orleans-based Entergy after federal and state regulators approved the sale of the reactor, closed since 2014. It marked the first permanent transfer of an operating license to a nuclear cleanup specialist for accelerated decommissioning. (AP Photo/Jessica Hill)

In this undated photograph obtained by The Associated Press, a UAV-X drone flown by Yemen's Houthi rebels is seen in Hodeida, Yemen. A Yemen rebel drone strike this week, likely by UAV-Xs, on a critical Saudi oil pipeline shows that the otherwise-peaceful sandy reaches of the Arabian Peninsula now are at risk of similar assault, including an under-construction nuclear power plant and Dubai International Airport, among the world's busiest.
