Tensions are getting a little higher as Iran presses US.
“Uranium as it is taken directly from the Earth is not suitable as fuel for most nuclear reactors and requires additional processes to make it usable. Uranium is mined either underground or in an open pit depending on the depth at which it is found. After the uranium ore is mined, it must go through a milling process to extract the uranium from the ore. This is accomplished by a combination of chemical processes with the end product being concentrated uranium oxide, which is known as “yellowcake”, contains roughly 60% uranium whereas the ore typically contains less than 1% uranium and as little as 0.1% uranium. After the milling process is complete, the uranium must next undergo a process of conversion, “to either uranium dioxide, which can be used as the fuel for those types of reactors that do not require enriched uranium, or into uranium hexafluoride, which can be enriched to produce fuel for the majority of types of reactors”[3]. Naturally-occurring uranium is made of a mixture of U-235 and U-238. The U-235 is fissile meaning it is easily split with neutrons while the remainder is U-238, but in nature, more than 99% of the extracted ore is U-238. Most nuclear reactors require enriched uranium, which is uranium with higher concentrations of U-235 ranging between 3.5% and 4.5%.”
Have a great Independence Day, folks! Enjoy the beach, BBQ, and fireworks but let us never, ever forget what we celebrate.
E pluribus unum over and out!
Russia has admitted a submersible involved in the country’s worst naval accident in more than a decade was nuclear powered, nearly three days after it caught fire during a top secret mission off the northern coast.
Defence minister Sergei Shoigu told president Vladimir Putin that the submersible’s nuclear reactor was “completely isolated and unmanned” and in full working condition, according to a transcript published on the Kremlin’s website on Thursday.
Mr Shoigu said the fire began in the submersible’s battery compartment, which then spread, killing 14 sailors from smoke inhalation and injuring an unspecified number of others. The sailors evacuated some of the people on board, then isolated the fire at the cost of their own lives, Mr Shoigu said.
The Kremlin has said it will not name the ship or clarify its mission. Russian media have reported that the fire broke out on an AS-31 submarine complex known as the Losharik, which normally travels under a larger submarine to avoid detection and can itself release another, smaller submersible.
One of the Russian navy’s most secret vessels, the Losharik is built to dive much deeper than an ordinary submarine and can survey the ocean floor.
The accident was Russia’s most fatal submarine tragedy since a fire killed 20 and injured 21 during sea trials of a nuclear-powered submarine in the Sea of Japan in 2008.
