Two New Elements Added To Periodic Table: Ununquadium And Ununhexium-Elements with Atomic Number 114 and 116

Two new elements have been added to the periodic table after a three-year review by the governing bodies of chemistry and physics.

The elements are currently unnamed, but they are both highly radioactive and exist for less than a second before decaying into lighter atoms. The table is the official compedium of known elements, organised according to properties of their atomic structure.

Details have been published in the journal Pure and Applied Chemistry. The review was conducted by a joint working party of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP).

In recent years, there have been several claims by laboratories for the discovery of new chemical elements at positions 113, 114, 115, 116 and 118 on the periodic table. The working party concluded that elements 114 and 116 fulfilled criteria for official inclusion in the table. The others, as yet, do not.

The new elements have temporary titles of ununquadium and ununhexium, but final names have Read more…

New leak seen at Japan quake-hit plant

A new leak of radioactive water has been found at Japan’s Fukushima nuclear power plant, adding to the woes of the Asian country’s nuclear crisis.

Tokyo Electric Power Company (TEPCO), the operator of the plant, said on Thursday that up to 57 tons of contaminated water has leaked from a storage facility, Reuters reported.

The environmental group, Greenpeace, has criticized the Japanese government’s assessment of the contamination level, saying, “Radioactive hazards are not decreasing through dilution or dispersion of materials, but the radioactivity is instead accumulating in marine life.”

“Our data show that significant amounts of contamination continue to spread over great distances from the Fukushima nuclear plant,” the group added.

Greenpeace has also accused TEPCO of covering up the actual severity of the disaster in the Asian Read more…

Fukushima Reactor 1 melted down, 2 and 3 may have too

Yesterday, TEPCO, the company responsible for running the Fukushima nuclear reactors, released a provisional analysis of the events that occurred in Unit 1, one of the reactors that was active when the tsunami struck. In five stark pages, the report lays out the impact of the tsunami on the facility: water levels that plunged below the bottom of the fuel, a complete meltdown of the nuclear fuel, and extensive damage to the reactor vessel.

The new analysis was enabled by the recent installation of air purifiers that let personnel reenter the reactor control room for the first time. Once inside, they were able to recalibrate some of the instruments that have been monitoring the reactor core; Read more…

Nuclear plant workers release unknown amount of radioactive tritium into Mississippi River

(NaturalNews) Workers at the Grand Gulf Nuclear Plant in Port Gibson, Miss., last Thursday released a large amount of radioactive tritium directly into the Mississippi River, according to the US Nuclear Regulatory Commission (NRC), and experts are currently trying to sort out the situation. An investigation is currently underway to determine why the tritium was even present in standing water found in an abandoned unit of the plant, as well as how much of this dangerous nuclear byproduct ended up getting dumped into the river. Many also want to know why workers released the toxic tritium before conducting proper tests.

The Mississippi Natchez Democrat reports that crews first discovered the radioactive water in the plant’s Unit 2 turbine building after heavy rains began hitting the area last week. Unit 2 was a partially-constructed, abandoned structure that should not have contained any radioactive materials, let alone tritium, which is commonly used to manufacture nuclear weapons and test atomic bombs (http://www.nirs.org/radiation/triti…).

The hereditary communist dictatorship in North Korea reports on the spread of radiation from the Fukushima nuclear plant, but it has all but fallen off the corporate media radar screen here. Monitoring stations across North Korea from April 11 to 17 detected iodine-131 and cesium-137 in the air above Wonsan in the southeast and Chongjin in the southeast, according to the country’s state-run media.

Here is a recent map showing the spread of cesium-137. Note the increased concentration over the United States.

Japan stops leaks from nuclear plant

TOKYO (Reuters) – Engineers have stopped highly radioactive water leaking into the sea from a crippled Japanese nuclear power plant, the facility’s operator said on Wednesday, a breakthrough in the battle to contain the worst nuclear crisis since Chernobyl.

However, Tokyo Electric Power (TEPCO) still needs to pump contaminated water into the sea because of a lack of storage space at the facility.

“The leaks were slowed yesterday after we injected a mixture of liquid glass and a hardening agent and it has now stopped,” a TEPCO spokesman told Reuters.

Desperate engineers had been struggling to stop the leaks and had used sawdust, newspapers and concrete as well as liquid glass to try to stem the flow of the highly-contaminated water.

Japan is facing its worst crisis since World War Two after a 9.0 magnitude earthquake and tsunami hit its northeast coast, leaving Read more…
