On 5 April 2011, the operator of the nuclear plant, Tokyo Electric Power Company (TEPCO), discharged 11,500 tons of untreated water into the Pacific Ocean in order to free up storage space for water that is even more radioactive. The untreated water was the least radioactively contaminated among the stored water, but still 100 times the legal ...
Since the accumulated radioactive water was a risk, TEPCO tried to transfer it. Assembly of hose fittings for Fukushima complex, Yokota AB. As the accumulated water in the basement of the turbine building of Units 2 and 3 was radioactive, TEPCO needed to remove it. They had initially planned to pump the water to the condenser (see diagram).
[3] [4] The release of radioactive isotopes from reactor containment vessels was a result of venting in order to reduce gaseous pressure, and the discharge of coolant water into the sea. [5] This resulted in Japanese authorities implementing a 30-km exclusion zone around the power plant and the continued displacement of approximately 156,000 ...
Japan began pumping more than a million metric tons of treated radioactive water from the destroyed Fukushima Daiichi nuclear power plant on Thursday, a process that will take decades to complete.
Highly radioactive water leaked from a treatment machine at the tsunami-hit Fukushima Daiichi nuclear power plant, but no one was injured and radiation monitoring shows no impact to the outside ...
Massachusetts environmental regulators have denied a request by the company dismantling a shuttered nuclear power plant to release more than 1 million gallons (3.8 million liters) of radioactive ...
Contaminated water continued to accumulate at the plant, and TEPCO announced plans to filter radioactive particles and discharge purified water. [60] In August, Japanese officials said highly radioactive water was leaking from Fukushima Daiichi into the Pacific Ocean at a rate of 270 tonnes (600 thousand pounds) per day.
In water, broad electron beams, as is the case in homogeneous surface contamination of skin, have d 80 about E/3 cm and R p about E/2 cm, where E is the beta particle energy in MeV. [ 24 ] The penetration depth of lower-energy beta in water (and soft tissues) is about 2 mm/MeV.
