Enrico Fermi became the first physicist to split the atom. His research pioneered the nuclear age.
Physicist Albert Einstein sends a letter to U.S. President Franklin D. Roosevelt, warning him that German researchers are working on an atomic bomb. Roosevelt forms a special committee to consider the military implications of atomic research.
The Manhattan Project was formed to secretly build the atomic bomb before the Germans. The Army appointed General Leslie Groves, the engineer responsible for building the Pentagon, to head the effort. At first, the research took place at several university laboratories.
Enrico Fermi demonstrated the first nuclear chain reaction in a lab under the squash court at the University of Chicago. In a nuclear chain reaction, a neutron splits one uranium atom into two smaller atoms, which in turn release energy and neutrons; these neutrons split other uranium atoms, releasing more energy and neutrons.
The United States exploded the first atomic device at a site near Alamogordo, New Mexico. At 5:30 am, July 16, 1945, scientists from Los Alamos, watching from observation bunkers 10,000 yards away, exploded an atomic device with a plutonium core, releasing a blast equivalent to 18,600 tons of TNT.
The United States drops atomic bombs on Hiroshima and Nagasaki, Japan. On August 6, 1945, a B-29 bomber–the Enola Gay–released a 9,700-pound uranium bomb, nicknamed Little Boy, over the city of Hiroshima in southern Japan. On August 9, another B-29 bomber–Bock’s Car–headed to bomb Kokura Arsenal; however, the pilot switched to his secondary target, Nagasaki, because of the weather over Kokura. Nagasaki was the home of a Mitsubishi torpedo manufacturing plant. Bock’s Car dropped a 10,000-pound plutonium bomb, nicknamed Fat Man, over the slopes of Nagasaki. Fat Man killed 40,000, injured 60,000, and destroyed three square miles of the city.

Fordow Fuel Enrichment Plant (Iran)
Fordow, near the city of Qom, is the site of an underground uranium enrichment facility at a former Islamic Revolutionary Guard Corps base. Existence of the then-unfinished Fordow Fuel Enrichment Plant (FFEP) was disclosed to the IAEA by Iran on September 21, 2009, but only after the site became known to Western intelligence services. Western officials strongly condemned Iran for not disclosing the site earlier; although some reports claim that the site was.under U.S. surveillance.
The Bushehr Nuclear Power Plant (Iran)
In March 2009, the head of Russia’s state nuclear power corporation Rosatom, Sergei Kiriyenko, announced that Russia had completed the construction of the plant. A series of pre-launch tests were conducted after the announcement. On September 22, 2009, it was reported that the first reactor was 96% complete and final testing would begin in the near future. In early October final testing was started.

Iran Rejects UN-Brokered Deal
Iran said, “No thanks,” on November 18, 2009 to an offer that would have resulted in the shipment of about 70% of its low-enriched uranium stockpile to Russia and France, and delayed Iran’s ability to fuel a nuclear weapon by about a year. Iran has counter-offered, saying it would consider other options in regard to its uranium, as long as the supply remained in the country. Reported by CBN, and the majority of news agencies.
The Year of the Bushehr
On January 10, Iran announced to the public that the Bushher reactor would be opening in the near-future, declaring 2010 the “year of Bushehr” On August 13, 2010 Russia announced that fuel would be loaded into the plant beginning on August 21, which would mark the beginning of the plant being considered an active nuclear facility. Within six months after the fuel loading, the plant was planned to be fully operational.An official launch ceremony was held on August 21, 2010 as Iran began loading the plant with fuel.
Underestimating Iran’s Intentions (January 2010)
Although they have opposed the project in the past, Western governments now stress that they have no objection to the demonstrably peaceful aspects of Iran’s nuclear program such as Bushehr, according to the BBC. Spokesman of the United States Department of State, Darby Holladay, stated that the United States believes the reactor is designed to produce civilian nuclear power and does not view it as a proliferation risk.
Iran Gets More Boisterous
On November 27, 2010 the head of the Atomic Energy Organization of Iran declared that “All fuel assemblies have been loaded into the core of the reactor” and they were hoping that the facility “will hook up with the national grid in one or two months.”The plant is to be operated by Russian specialists. Russia also provides the nuclear fuel for the plant, and spent fuel is sent back to Russia. The Bushehr plant will satisfy about 2% of Iran’s projected electricity consumption.
Islamists Rejoice over Iran’s Nuclear Advancements (November 2010)
The former head of Pakistan’s Inter-Services Intelligence hailed Iran’s launch as a positive move in the Muslim world, and he also said that an anti-Iran campaigns by the US and Israel stems from Iran’s Islamic status. “Bushehr Nuclear Power Plant is a victory for Iran and indicates that Iranians do their best to achieve their peaceful objectives but the US and Israel are not ready to accept this achievement.”
Bushehr Nucleat Power Plant Almost at Full Capacity
Director Fereydoun Abbasi announced on February 15, 2011 that the Bushehr nuclear power plant had reached 75 percent of its power generation capacity. Abbasi was quoted “that hopefully the Bushehr plant will be connected to the national grid at its full capacity in late April.”
North Korea Third Nuke Test
On February, 21 2011 Reuters reported that N. Korea is digging at the site where it has launched two nuclear tests. This undertaking suggests N. Korea is preparing a third test, the South’s Yonhap news agency said. Tensions rose on the divided peninsula when 46 sailors were killed in an attack in March on a South Korean naval vessel. North Korea, which has denied responsibility, shelled the southern island of Yeonpyeong in November, killing four people and sparking fears of possible all-out war.
On May 24, 2011, IAEA Director General Amano released a report which assessed that the facility destroyed (bombed) by Israel unilaterallyon September 6, 2007, which it believed had hosted a nuclear reactor under construction was indeed a nuclear reactor.U.S. intelligence officials claimed low confidence that the site was meant for weapons development. Syrian President Bashar al-Assad has said the site in discussion was just “a military site under construction.”Iran Testing Missiles to Carry Nuclear Weapons
On June 29, 2011 CNN reported that Iran has been carrying out covert tests of missiles capable of delivering a nuclear payload, UK Foreign Secretary William Hague said Wednesday, in contravention of a U.N. resolution.It has also said it wants to enrich uranium to “levels far greater than is needed for peaceful nuclear energy,” Hague said.Iran’s development of missile and nuclear fuel technology has led to U.N. sanctions and accusations from the United States that the clerical regime is trying to develop nuclear weapons.
Bushehr Nuclear Power Plant at Full Capacity
On August 30, 2011 at 18:47 local time the power unit 1 was brought to 100 percent of its power generation capacity.
Fordow Facilty Moves to Clandestine Location
In September 2011, Iran said it would move its production of 20% LEU to Fordow from Natanz. Enrichment started in December 2011. According to the Institute for Science and International Security two possible locations of the facility are suspected.
Official Launch of Bushehr Nuckear Facility
The plant started adding electricity to the national grid on September 3, 2011, and the official inauguration was held on 12 September. By the inauguration time the plant operated at 40% capacity, while the full projected capacity of the first unit is 1,000 megawatts. Under the terms of Russia–Iran agreement, approved by the International Atomic Energy Agency, Russia will be responsible for operating the plant, supplying the nuclear fuel and managing the spent fuel for the next two or three years before passing full control to Iran.
Explosion Near Tehran
In late November 2011 top Israeli security official said that a recent explosion that rocked an Iranian missile base near Tehran could delay or stop further Iranian surface-to-surface missile development. Earlier this month, Iran reiterated that the explosion at a military base near Tehran that killed at least 17 members of the Revolutionary Guards was an accident.
North Korea Supplying Syria, Iran
Prohibited Nuclear Technology is being supplied by North Korea to Syria and Iran reported the German newspaper Die Welt reports on November 28, 2011 that Pyongyang has provided the countries with “maraging steel,” used to upgrade missiles and centrifuges. It has been known for years that Iran is trying to obtain the steel through its clandestine purchasing networks around the world. The steel would enable Tehran to construct modified centrifuges, which would in turn allow it to enrich higher quality Uranium at a faster speed.
“Maraging Steel” Supplied by North Korea to Syria
According to the November 28 report by the German newspaper, Die Welt the delivery of the steel is to be used for upgrading Syrian scud missiles. Syria is building a new missile factory near Homs. According to other reports, the factory is partly funded by Iran, and is expected to become operational within 18 months. Maraging steel would significantly upgrade Syria’s Scud missile capabilities and the amount of damage their warheads could inflict.
Syria Supplying Hezbollah with Missiles
The German newspaper, Die Welt cited unnamed “Western security sources,” also reported that Syria is trying to supply Hezbollah with M-600 missiles that have a range of up to 300 kilometers. These would be equipped with warheads that were upgraded using maraging steel. Several UN resolutions forbid North Korea from exporting weapons or weapons technology.
Footage of WMD Stockpiles Uncovered in Libya
On December 14, 2011 MEMRI (Middle East Media Research Institute) brought forth an insightful video out of the Arab world. New footage has emerged out of Libya featuring stockpiles of weapons of mass destruction. Stockpiles of mustard gas, nerve gas, as well as plant for their production” in the Al-Rawagha and Sokna regions. New depositories containing internationally prohibited gases were found near the city of Sokna.
On July 23, 2012 Syria admitted to manufacturing and possessing a stockpile of chemical weapons which it claims are reserved for national defense against foreign countries. Western non-governmental organizations have stated they believe Syria has an active chemical weapons program. Syria is one of seven non-signatories to the Chemical Weapons Convention of 1993, though it denied that it had chemical weapons until admitting it possessed such weapons in 2012.
Iran Uranium Enrichment Capacity Surging
McClatchy-Tribune reported on August 24, 2012 that Iran has significantly expanded its uranium enrichment capability at its Fordow facility, according to U.S. officials and others briefed on the finding. The move could shorten the time Tehran would need to build a nuclear weapon.
Iran Close to Building A-bomb Like Never Before
On August 30, 2012 UN inspectors reported that Iran had taken new efforts to produce enriched uranium. Iran doubled the number of centrifuges to enrich uranium at Ford underground complex, officials said. In the quarterly report, the IAEA said that Iran had 2,140 centrifuges, and since 2010 Iran had produced nearly 190 kilograms of highly enriched uranium.
Back in May 2012, the head of the Atomic Energy Organization of Iran Fereydoun Abbasi-Davani said that Iran would continue to enrich uranium in the quantities sufficient for the Islamic Republic, despite the protests of the international mediators. It appears that the pace of this work has increased. It was particularly reported that IAEA experts discovered uranium enriched to 27 percent at one of Iran’s nuclear facilities, which contradicted to Iran’s official promises not to overcome the enrichment limit of 20 percent.
In July of 2012, according to Interfax, Ayatollah Khamenei said that the level of enrichment of uranium for nuclear reactors would reach 56 percent if the international community continued to put pressure on Iran.
August 2012 data from the IAEA and Israeli military intelligence strongly suggest that Iran, to all appearance, possesses the amount of uranium to make a nuclear bomb. Apparently, this quantity, as well as quality, will grow. Most likely, the country is right now on the verge of developing nuclear weapons.
Decontamination problems persist at Japan’s crippled nuclear power plant.
Tons of contaminated soil is stored temporarily in huge lots. A former worker told reporters, “We’d decontaminate around a house,” he said, “but if it rained, more contaminated earth from outside that perimeter would just pour right in.” Many towns here don’t want it, so the waste, just like the residents, sits in limbo. 
It seems like an endless process and the likelihood of this problem improving will take a very long time.
Following typhoon, record levels of “high toxic” nuclear material near Fukushima reactor.
Officials: Typhoon caused significant increase in radioactive releases from Fukushima. Record levels of ‘highly toxic” nuclear material found in ground outside reactor. Among the most poisonous substances at plant.
Very high abnormality rates in Fukushima insects eating radiation contaminated leaves.“Groundbreaking” study reveals Fukushima nuclear waste is poisoning wildlife: Up to 99% of offspring died after eating ‘low-level’ contaminated food: “Very high” abnormality rates including “severe and rare” deformities. 
 Energy News, Oct. 10, 2014
Seventy years ago, following the Potsdam Declaration by the Allies on 26 July 1945 and the refusal of Japan to surrender under its terms, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki on 6 August and 9 August respectively. Japan had already attacked Pearl Harbor in 1941.
The robots sent into Fukushima have ”died.” The remote-controlled robots that were sent into the site of the 2011 meltdown at the Fukushima Daiichi nuclear power plant in Japan have reportedly “died” thanks to incredibly high amounts of leaked radioactive materials destroying their wiring.
The robots, which take years to manufacture were designed to swim through the underwater tunnels of the now-defunct cooling pools, and remove hundreds of extremely dangerous blobs of melted fuel rods. But it looks like that’s not going to happen any time soon.
North Korea’s latest test proves he can hit anywhere in the world. Kim Jong-un’s latest nuclear provocation was an ICBM without a nuclear tip, but it displayed to the world that he has the ability to strike with great precision. N. Korea has Asia and the rest of the world on edge.
