By reconstructing a nearly forgotten 1938 experiment, scientists have uncovered new significance in an early observation of deuterium-tritium fusion that still shapes nuclear science today. (Artist’s concept). Credit: SciTechDaily.com Physicists confirm DT fusion insights from a 1938 experiment. The findings connect past theory with current fusion efforts. A team at Los Alamos National Laboratory has successfully recreated a significant yet largely overlooked physics experiment: the first recorded observation of deuterium-tritium (DT) fusion. Their updated version of the 1938 experiment, recently detailed in Physical Review C, reaffirms the pivotal role of University of Michigan physicist Arthur Ruhlig. Ruhlig’s original work likely...

Vienna (AFP) - The UN's nuclear watchdog said Monday that Iran's stock of heavy water for reactors has surpassed the limit set under its agreement with world powers. The International Atomic Energy Agency said in a statement that Iran's heavy water production plant was in operation and that its stock of heavy water reserves was 131.5 tonnes, above the 130-tonne limit. In Vienna, an IAEA spokesperson said: "On 17 November, the Agency verified that the Heavy Water Production Plant (HWPP) was in operation and that Iran’s stock of heavy water was 131.5 metric tonnes." Heavy water is not itself radioactive...

Israel’s military warned people Thursday to evacuate the area around Iran’s Arak heavy water reactor. The warning came in a social media post on X. It included a satellite image of the plant in a red circle like other warnings that proceeded strikes.

Secretary of State John Kerry confirmed on Wednesday that Iran has removed the calandria, or central vessel, of its nuclear reactor at Arak, and it will be filled with concrete within hours. Iranian media reported earlier this week that the Islamic Republic had removed the core of the Arak heavy-water nuclear reactor, the fate of which was one of the sticking points in nuclear negotiations between Iran and the six world powers. "Just yesterday, the foreign minister (of Iran) reported to me that the calandria of the plutonium nuclear reactor is now out and in the next hours it will...

WEST (Credit: CEA-IRFM). A new record in fusion has been achieved using a device internally clad in tungsten, a development that could set the pace for helping make fusion energy viable at the commercial scale. Princeton Plasma Physics Laboratory (PPPL), a U.S. Department of Energy (DOE) facility, reports that the device was able to sustain hot fusion plasma nearing temperatures of 50 million degrees Celsius for a record-breaking six minutes. Relying on 1.15 gigajoules of power, the latest achievement saw a 15% increase in energy, as well as twice the density of previous experiments. The new milestone was set using...

Inside JET's torus, with superimposed plasma. (UKAEA) Late last century, the Joint European Torus (JET) near Oxford, UK, churned out 22 megajoules of energy in what was, at the time, a record in fusion power. Now, experimental upgrades have brought the facility into line with the technology anticipated for a major international project, resulting in the production of nearly three times that amount of power. The advances are a major step forward for tokamak-based fusion, bringing us ever closer to a balance point where we can harvest a near endless stream of energy without the cost of polluting emissions or...

President Joe Biden on Tuesday praised an Australian company that makes chargers for electric vehicles for agreeing to build a manufacturing facility in Tennessee, saying the plant will "have a ripple effect" far beyond the state. The company, Tritium, and the White House say the new plant will produce up to 30,000 electric vehicle chargers per year and create 500 local jobs. "The new manufacturing facility Tritium announced today is more than just great news for Tennessee. Yes, it's going to create more than 500 good-paying jobs in Tennessee, but it can deliver greater dignity and little more breathing room...

AIKEN, SC (WFXG) - According to Savannah River Site officials, a potential security event is in progress that has triggered emergency response activities at the Department of Energy’s Savannah River Site. Site barricades are currently closed to incoming traffic. There is no indication of a consequence beyond the Savannah River Site boundaries. WFXG has a reporter on the way and will update you as we learn

Scientists working on the Xenon1T experiment have detected more activity within their detector than they would otherwise expect. There are three potential explanations for the new signal from the Xenon1T experiment. Two require new physics to explain, while one of them is consistent with a hypothesised dark matter particle called a solar axion. There are several theories to account for what that particle might be like. The most favoured one has been the WIMP, or Weakly Interacting Massive Particle. Physicists working on the Xenon series of experiments have spent more than a decade hunting for signs of these WIMPs. ......

Breaking the Light Speed Barrier with David Sereda by Diane M. Cooper How do alien spacecraft get into our Solar System from those galaxies far, far away? David Sereda thinks he has found the answer to this question. In this technically satisfying but extremely readable interview, Sereda describes some of the experiences with alternative energy that eventually led to his "revelation" about the way alien spacecraft maneuver. And he explains to us just exactly how they may be able to move at the speed of light. -------------------------------------------------------------------------------- The spacecraft painting is © Douglas Taylor and used with permission.

J.W. Ramp captured a series of images of pistol sights under various lighting conditions. Some of these photosshows you the different conditions and the pistol sight picture. Recently a discussion came up in the Primary & Secondary Discord chat server regarding recommended pistol sights for defensive use. The two non-red dot suggestions that seemed the most popular were Tritium-based "night sights" (either front-only or all around) and a fiber-optic front sight with blacked-out rear. Having a handful of different sight setups on a few of my Glocks, I figured it’d be handy to compare them side-by-side in various lighting conditions...

Despite the objections of local fishermen, the tritium-tainted water stored at the Fukushima No. 1 nuclear plant will be dumped into the sea, a top official at Tokyo Electric says. “The decision has already been made,” Takashi Kawamura, chairman of Tokyo Electric Power Company Holdings Inc., said in a recent interview with the media. Tritium typically poses little risk to human health unless ingested in high amounts, and ocean discharges of diluted volumes of tritium-tainted water are a routine part of nuclear power plant operations. This is because it is a byproduct of nuclear operations but cannot be filtered out...

As the debate over which bathroom an individual should use based on their sexual identity heats up, we are witnessing the ignorant and brash nature of state enforcement of these edicts come to a head. It is not only a distraction and a means for the state to get involved in your bowel movements, but it paints the trans and gay community in a negative light by asserting there is some sexual stigma involved in relieving oneÂ’s bladder. The end result of such obstinate legalese clouding the minds of the public is going to be state violence initiated against individuals...

Two years after being fined for falsifying safety records, nine months after a transformer exploded at the Indian Point Nuclear Reactor just 37 miles from midtown Manhattan, and two months after Entergy - the plant's operator - shut down the Unit 2 reactor after a major power outage cut power to several control rods (when the company assured that no radioactivity was released into the environment), this afternoon NY Governor Andrew Cuomo said he learned that "radioactive tritium-contaminated water" had leaked into the groundwater at the nuclear facility in Westchester County. Cuomo, in a letter Saturday to the state Health...

N.K. building isotope separation facility to build more powerful nuclear bombs: U.S. institute 2015/09/16 04:54 By Chang Jae-soon WASHINGTON, Sept. 15 (Yonhap) -- A new facility under construction at North Korea's Yongbyon nuclear complex appears to be designed to separate isotopes from spent fuel that can be used in building nuclear weapons more powerful than plutonium or uranium bombs, a U.S. research institute said Tuesday. The assessment from the Institute for Science and International Security adds to growing concern that the communist nation is ramping up efforts to further strengthen its nuclear capabilities and could carry out its fourth nuclear...

Future aircraft could be powered by lasers and nuclear explosions if Boeing has its way. The aerospace firm claims a new-type of engine could produce energy-efficient thrust by firing lasers at radioactive material, such as deuterium and tritium. The technology could mean that planes and spaceships will require only a fraction of the power to operate, according to a recent patent filed by the company.

<p>ROCKFORD — A loss of power coming into the Byron nuclear plant caused one of two reactors to automatically shut down about 10:15 a.m. today.</p> <p>Backup diesel generators were activated after the power outage and were being used for safety equipment that vents heat from the reactor, according to a spokeswoman from the Nuclear Regulatory Commission in Lisle.</p>

Why NBC is "in the tank" for Barack Obama: The second largest company in the world is General Electric. GE owns NBC. It also builds nuclear power reactors. Is it any wonder then that NBC favored Obama from the start? According to the LA Times, “Obama is the largest beneficiary of money from companies that have a stake in nuclear energy’s future.” Are we surprised then that Tim Russert prematurely called Obama the Democratic nominee? Or that Russert allowed Obama to ramble on about how great nuclear power is on Meet the Press? Take a look at Obama's Exelon connection...

It began in late 2007 as a routine audit. Retail giant Wal-Mart noticed that some exit signs at the company's stores and warehouses had gone missing. As the audit spread across Wal-Mart's U.S. operations, the mystery thickened. Stores from Arkansas to Washington began reporting missing signs. They numbered in the hundreds at first, then the thousands. Last month Wal-Mart disclosed that about 15,800 of its exit signs – a stunning 20 per cent of its total inventory – are lost, missing, or otherwise unaccounted for at 4,500 facilities in the United States and Puerto Rico. Poor housekeeping, certainly, but what's...
