Experts talk about the consequences of the discharge of wastewater from Fukushima into the sea

The volume of wastewater from the Fukushima nuclear power plant that Japan plans to dump into the Pacific is negligible to lead to an environmental disaster, even in the case of poor quality treatment.

The above comments of Mr. Konstantin Roginsky, deputy director of the Institute of Oceanography of the Russian Academy of Sciences shared with the media on April 13.

“The amount of wastewater announced by the Japanese side is a small amount. This is a drop of water in the ocean. Even in the worst case, if the wastewater is poorly treated, this heavy water will sink to the bottom and lie at a depth of 5-6-8 km, ”said Mr. Roginsky.

The waste water is planned to be discharged into the ocean, not posing a threat to the ecosystem of the Sea of ​​Okhotsk, because the currents in that area go from north to south in the direction of the Russian scientist. Japan”.

The wastewater discharge will begin in about two years and the entire process is expected to take decades. (Image: Reuters)

According to Roginsky, the discharge of wastewater from the Fukushima nuclear power plant does not pose a threat to the Sea of ​​Japan, which is separated from the Pacific by islands of Japan. “US naval bases are much more harmful to Japan’s coastal fisheries,” added Roginsky.

“About 1.5 million tons of wastewater will be dumped into the ocean. Accordingly, the water is diluted, losing its natural salinity. This can be more harmful to marine organisms than it is with poor radiation release. They are used to living at a certain salinity, at a certain depth, in a certain chemical composition of water, ”explained the Russian expert.

Also commenting on the contemporary Japanese announcement of the discharge of wastewater from the Fukushima nuclear power plant, the expert of the Federal Council on Agricultural Policy – Food and Environmental Management, Ms. Natalia Sokolova undertook that if the wastewater is properly purified, there will be no radioactive threat to Russia.

“Right now, the amount of liquid accumulated is very large. Most of it is regular water. If purified from all harmful impurities, including tritium, the wastewater can be safely discharged into the oceans, as well as the coastal waters of other countries will not be affected. “, Ms. Sokolova shared with Sputnik.

According to the ecologist, discharging water from nuclear power plants is a common process for operating plants. But Fukushima is an emergency, so it is not known whether or not an operation will be able to proceed. It will become clear by 2023 whether wastewater can be filtered to the required parameters.

“Rigorous laboratory analyzes should be performed during the entire wastewater purification process. Two years prior to discharge is called approximate figure. I am sure that the Japanese government will make a decision on the outcome of the wastewater purification process. So far, these are just plans and the reality is that not all wastewater can be 100% purified ”, believes Ms. Sokolova.

Japan insists it is safe to discharge water from the plant as it has been treated to remove most of the radioactive elements and will be diluted. (Image: Reuters)

Meanwhile, Dmitry Lisitsyn, President of the Far East (Russia) environmental protection organization, said that the discharge of wastewater from the Fukushima nuclear power plant in Japan would lead to radioactive pollution. was brought to the heart of the North Pacific, where Pacific salmon are inhabited.

“The Fukushima nuclear power plant is located on the Pacific coast of Honshu Island. When radioactive pollution enters the Pacific off the coast of Honshu, they are quickly transported to the northeast by the Kuroshio currents, then into the North Pacific stream. All polluted wastewater is sent directly to the North Pacific. How does this threaten Russia? The fish forage in the North Pacific, then infiltrate the Russian table and there will be more before the polluted wastewater completely disappears, “RIA quoted Mr. Lisitsyn.

Lisitsyn noted six Pacific salmon species live in the Far East. They spawn in rivers, feed and grow in the ocean. Specifically in the central region of the North Pacific. This is exactly the site where this pollution was done.

What does the IAEA say?

Director General of the International Atomic Energy Agency (IAEA) Rafael Mariano Grossi, welcomed the decision of the Japanese Government to discharge wastewater from the damaged Fukushima nuclear power plant into the sea and promised that the organization would assistance to avoid negative consequences.

“I welcome Japan’s announcement of how they will treat wastewater stored at the Fukushima nuclear power plant. The IAEA will work with Japan before, during and after discharge to help ensure this is done without negatively affecting health and the environment, ”wrote Grossi on Twitter.

According to Mr. Grossi, the controlled discharge of water into the sea is regularly used by nuclear power plants operating in the world and in the region, they comply with strict environmental safety standards and regulations. .

The start of wastewater discharge is expected to be around 2023. At the current rate of storage in reservoirs, all available reservoirs will be filled by the end of 2022.

Earlier, speaking at a press conference on April 13, Japanese Prime Minister Suga Yoshihide announced that it would discharge more than 1 million tons of wastewater from the Fukushima nuclear power plant into the sea, saying that the discharge of water into Thai waters Binh Duong was the “most realistic” and “inevitable” option to achieve the recovery of Fukushima.
