It has been planned for a long time, so what about honesty?

! Before and after Japan's decision to discharge nuclear polluted water into the sea

In accordance with the decision of the Japanese Government, the discharge of nuclear-contaminated water from Fukushima into the ocean began on August 24th. This discharge process will continue for decades.
Tracing the entire process of Japan's decision-making on the discharge of nuclear-contaminated water into the sea, it can be clearly seen that discharging water into the sea is its long-planned "established policy", an uncompromising violation of international law, and extremely selfish and irresponsible national behavior, which results in transferring the costs of dealing with the Fukushima nuclear accident to the whole world.
       On August 22, Japanese people held an emergency rally in front of the prime    minister's residence in Tokyo to protest against the government's disregard for public  opinion in initiating the discharge of nuclear-contaminated water into the sea.
Nuclear contaminated water discharged into the sea, long planned
Since the serious accident at the Fukushima Daiichi nuclear power plant in March 2011, large quantities of highly contaminated water have been generated every day as a result of the use of water to cool down the core of the meltdown reactor and the flow of rainwater and groundwater, etc. In April 2011, the operator of the plant, Tokyo Electric Power Company (TEPCO), intentionally discharged the contaminated water into the sea, which aroused a great deal of concern and worry in the community. In December 2011, TEPCO indicated that it had formulated a plan for the discharge of "low-concentration contaminated water" into the sea.
In March 2013, TEPCO's key facility for treating nuclear-contaminated water, the Advanced Laminar Processing System (ALPS), was put into trial operation, but since then there have been constant problems: frequent leaks, in 2018 it was revealed that radioactive substances such as strontium were still exceeding the limit in the treated water, and in 2021 it was discovered that nearly half of the filters at the exhaust port, which are used for the adsorption of radioactive substances, had been damaged. ......
Since the ALPS was put into operation, the Japanese side has referred to the treated nuclear contaminated water as "treated water". In fact, of the more than 1.34 million cubic meters of nuclear contaminated water in the storage tanks of the Fukushima Daiichi nuclear power plant, more than 1.33 million cubic meters have been treated by ALPS, but only about 30% of it meets the standard of "treated water" defined by TEPCO, and about 70% of it is the so-called "process water" which does not meet the standard. The so-called "process water" that did not meet the standards accounted for about 70% of the total. Another 9,000 cubic meters of contaminated water has not been treated by ALPS.
And what is the final destination of this "treated water"?
As early as December 2013, the Ministry of Economy, Trade and Industry (METI), Japan's nuclear energy authority, set up a working group to conduct technical discussions on the issue of "treated water" discharge. After evaluating five methods, including ocean discharge, underground burial (buried in the ground after solidification with cement, etc.), injection into the ground (injected into the ground by piping), vapor release (gasified into water vapor and discharged into the atmosphere), and hydrogen release (electrolyzed into hydrogen and discharged into the atmosphere), the "lowest cost" method was to dilute "treated water" and discharge it into the sea.
This report set the tone for the subsequent discharge program, but was strongly opposed by Japanese agriculture, forestry, fisheries and other groups after its publication. Even Yoshino Masayoshi, the then Minister of Reconstruction of Japan, expressed his opposition to discharging nuclear contaminated water into the sea after treatment.
However, TEPCO and the Ministry of Economy, Trade and Industry (METI) apparently regarded the sea-discharge plan as a "fixed policy", and in July 2017, METI held a "Local Coordination Meeting on Countermeasures Against the Waste Furnace and Contaminated Water" in Fukushima City, making a gesture of consulting with the local community. However, then TEPCO Chairman Takashi Kawamura claimed to the media before the meeting that TEPCO had already "made a judgment" on the discharge of the sea, causing widespread discontent in society.
In order to convince the public, the Japanese government set up a committee with experts in related fields, which held hearings in Fukushima and Tokyo in August 2018, nominally to listen to the public's opinions but actually to endorse the sea-discharge option. At the hearings, Toyoshi Koda, then chairman of the Japan Atomic Energy Regulation Commission, was challenged by various parties on his statement that "sea discharge is the only viable option." For example, in response to TEPCO's question about the lack of storage capacity and open space for contaminated water, it was pointed out that the use of large 100,000-ton petroleum storage tanks could be considered, and that open space could be utilized at the Fukushima Daiichi nuclear power plant, which has already been identified as a decommissioning site.
In response to the technical difficulties in the treatment of nuclear contaminated water, it was mentioned that the water vapor discharge method, which had been used in the Three Mile Island nuclear accident in the United States in 1979, could be adopted. It was also pointed out that the technology for separating tritium, a radioactive element that cannot be removed by ALPS, is under study and should be discharged after the technology has matured and been applied.
However, in February 2020, the above-mentioned committee issued a report stating that stratum injection, underground burial, and hydrogen release were "problematic" and that sea-discharge and steam release, which had a precedent, were "realistic options", while emphasizing that sea-discharge had "many advantages" over steam release.
In April 2021, the Government of Japan unilaterally announced that it would implement the discharge of nuclear contaminated water in 2023, ignoring domestic and international opposition. Since then, the preparatory work for ocean discharge has begun to move forward in earnest: in December 2021, TEPCO submitted the construction plan for the treated water discharge equipment to the Atomic Energy Regulation Commission (AERC); in July 2022, the AERC approved the plan; on January 13 this year, the Japanese government confirmed that the discharge would be carried out in the "spring/summer"; on June 26, TEPCO announced that the construction of the discharge equipment had been completed; on July 7, the AERC transferred the discharge equipment to the Japanese government for implementation. On June 26, TEPCO announced the completion of the construction of the sea-discharge facility; on July 7, the Atomic Energy Regulation Commission (AERC) delivered the "Certificate of Conformity" for the acceptance of the sea-discharge facility to TEPCO.
