What TEPCO Would Like to Convey regarding ALPS Treated Water
Advanced Liquid Processing System
About
TEPCO is steadily proceeding with the decommissioning of the Fukushima
Daiichi
Nuclear Power
Station one by one, prioritizing safety first, and working to
reduce risks.
As part of the decommissioning process, ALPS treated water has been discharged into the sea
upon ensuring safety under the government basic policy.
TEPCO will convey regarding ALPS treated water in easy-to-understand manner on
this site.
ALPS treated water measures are part of decommissioning to reduce radiation risks
ALPS treated water has been discharged into the sea upon ensuring safety
The specially designed equipment for removing radioactive materials
Removes radioactive materials other than tritium
Total amount of pure tritiated water is equivalent to one tube of eye drops
Tritiated water exists as a liquid with almost the same properties as water
Tritium is also found in things around us and in our bodies
Tritium is not accumulated in our bodies
The energy of the radiation emitted by tritium is weak
Dilute tritium with seawater to ensure that the water is safe
Water to be discharged into the sea meets the government’s safety standard
Total annual amount of tritium to be discharged is below the target at the time of operation
Tritium has been discharged from nuclear facilities in Japan and overseas
Tritium concentration is the same as surrounding seawater 2-3 km away from the discharge point
Measure and analyze seawater and fish, and analysis results are available on the website
The effect of the discharge of ALPS treated water into the sea on the public is minimal
The International Atomic Energy Agency (IAEA) and experts from around the world review the safety
Rearing records of fish, shellfish and etc. are available on the TEPCO's website
ALPS treated water measures at the Fukushima Daiichi Nuclear Power Station has been safely and steadily proceeded as part of the decommissioning process to reduce radiation risks.
In order to proceed with the decommissioning of the Fukushima Daiichi Nuclear Power Station, ALPS treated water has been discharged into the sea upon ensuring safety.
ALPS is the specially designed equipment to remove radioactive materials contained in water.
ALPS removes radioactive materials other than tritium until they meet the government’s regulatory standards.
ALPS treated water, etc. is stored in over 1,000 tanks. The total amount of pure tritiated water in them is equivalent to one tube of eye drops.
Tritiated water exists as a liquid with almost the same properties as water.
Tritium is found in things around us, such as rain, the sea, drinking water, and food, as well as in our bodies.
It has been confirmed that tritium is not concentrated or accumulated in our bodies.
The energy of radiation emitted by tritium is so weak that it can be prevented by a sheet of paper.
The tritium remaining in ALPS treated water is diluted with seawater to ensure that the water is safe.
The tritium concentration in the water to be discharged into the sea fully meets the government's safety standard.
The total annual amount of tritium to be discharged into the sea has been appropriately managed so that it has been below the management target value at the time of operation of the Fukushima Daiichi Nuclear Power Station.
Tritium has been discharged from nuclear facilities in Japan and overseas, after meeting safety standards.
Tritium concentration is evaluated to be the same as that of the surrounding seawater, 2-3 km away from the discharge point.
The Japanese government, Fukushima Prefecture, and TEPCO measure and analyze seawater and fish in a planned manner, and all analysis results are available on the website.
The effect of the discharge of ALPS treated water into the sea on the public is minimal, well below that of radiation exposure from dental x-rays.
The International Atomic Energy Agency (IAEA) and experts from around the world have been reviewing the safety of the discharge of ALPS treated water into the sea.
TEPCO makes rearing records of fish, shellfish and etc. in the seawater which ALPS treated water is added widely available on social media.
