GE-Hitachi Proposes to Burn U.K. Plutonium Stockpile | The Energy Collective

GE Hitachi Nuclear Energy has proposed to the U.K. government to build an advanced nuclear reactor that would consume the country’s stockpile of surplus plutonium.

The technology is called PRISM, which stands for Power Reactor Innovative Small Module. If accepted, it would be very different than the other proposals to process plutonium, including those that would turn it into mixed oxide fuel (MOX).

According to GE Hitachi, the PRISM reactor disposes of a great majority of the plutonium as opposed to simply reusing it over again. This process takes it out of circulation forever.

The UK government had considered building a MOX plant at the Sellafield site where the plutonium is stored, but it canceled those plans as the Japanese government stopped orders for MOX following the Fukushima earthquake.

福島原発の土壌からプルトニウム 東電発表「ごく微量」  :日本経済新聞

TOKYO (Kyodo)–Plutonium has been detected in soil at five locations at the crippled Fukushima Daiichi nuclear power plant, Tokyo Electric Power Co. said Monday.

The operator of the nuclear complex said that the plutonium is believed to have been discharged from nuclear fuel at the plant, which was damaged by the devastating March 11 earthquake and tsunami.

While noting that the concentration level does not pose a risk to human health, the utility firm said it will strengthen monitoring on the environment in and around the nuclear plant.

Meanwhile, high levels of radiation exceeding 1,000 millisieverts per hour have been detected in water in a trench outside the No. 2 reactor’s building at the nuclear plant, with the contaminated water suspected to have come from the reactor’s core, where fuel rods have partially melted, authorities said Monday.

    1. Plutonium, produced as a result of uranium fission, does not disperse easily because of its weight. It was likely released outside during the string of hydrogen explosions and fires at the Nos. 1, 2, 3 and 4 reactors….
    2. Plutonium is far more toxic than uranium. Exposure to plutonium-238, which emits neutrons, is known to increase the risk of cancer.
  2. Plutonium detected in soil at Fukushima nuke plant
    1. the plutonium, the presence of which was confirmed for the first time in the ongoing nuclear emergency, could have been discharged from nuclear fuel at the plant hit by the devastating March 11 earthquake and tsunami, but does not pose a major risk to human health.
    2. Plutonium is more toxic than other radioactive substances such as iodine and cesium, but the levels confirmed from soil samples taken at the plant on March 21 and 22 were almost the same as those from the fallout detected in Japan following past nuclear tests by the United States and Russia, said the utility known as TEPCO.

The government’s Nuclear and Industrial Safety Agency said it remains unknown which reactor plutonium came from and that TEPCO and the science ministry will strengthen monitoring on the environment both in the plant and outside of a 20-kilometer exclusion zone set by the government

Plutonium detected at Fukushima

From this morning’s news shows: traces of plutonium radiation have been detected at the Fukushima Dai-ichi nuclear plant. This obviously confirms suspicions that the no. 2 reactor has some kind of leak, as was suspected by the highly irradiated water found in the trench and the turbine building yesterday/Sunday.

More updates on this as I get them.

Preventative measures in case of radiation exposure

As the situation in Fukushima remains critical and may still get worse, I’m re-posting some links to sources of information about iodine, potassium iodide, the Japanese diet, and various supplements. I have not tried any of these and amd not recommending them.  Please do your own research. Kelp is konbu 昆布 コンブ in Japanese.

Some people have expressed concerns over the lack of Potassium Iodide available at stores in Japan. Potassium Iodide is used to protect the thyroid gland from the effects of radiation exposure.

First off, in Japan, most druggist do not carry Potassium Iodide as one needs a prescription to buy it. Secondly, the average Japanese gets more than sufficient amounts of iodine in their regular foods that it is not necessary at all to supplement it.
