Signal: X users respond to Fukushima wastewater as fish samples collected

Scientists from Canada, China and South Korea have collected fish samples for testing from the water near Fukushima.

A team of international scientists collected samples of fish from the Hisanohama port on Thursday (19 October), approximately 50km south of the site of the ruined Fukushima Daiichi nuclear power plant, from which wastewater is being released.

The site closed in 2011 after a major earthquake and 15m tsunami caused the level 7-rated accident, which saw all four reactors written off.

On 24 August this year, Japan undertook its first discharge of treated wastewater from the Fukushima site, a move that drew criticism from local fishermen and prompted China and more recently Russia to ban all seafood and marine products from Japan, citing concerns over food safety.

According to the International Atomic Energy Agency (IAEA), the team included experts from laboratories in China, South Korea and Canada, as well as two staff from the IAEA’s own laboratories in Monaco. It reported that the team would be working from 16-23 October and would also be sampling fish from markets in the Fukushima Prefecture.

It stated: “The Agency’s samples will be used to corroborate Japan’s environmental monitoring and to assess the country’s relevant technical capabilities.”

Japan has been quick to emphasise the safety of its seafood, with the government posting this week about the Sakana and Japan Festival, which resumed in 2023 after facing three years of cancellations during the pandemic.

The festival is run by the Sakana and Japan Project, which is currently running a project named “Let’s eat Fukushima fish,” which includes a seafood cooking competition.

However, there has been scepticism from users of X (formerly Twitter) across the globe, who have taken to the platform to share their concerns. One user posted her discomfort with the phrase used to describe tritium (the radioactive isotope of hydrogen) in the Reuters report.

Another commented on The Japan Times’ post about the Ikejime fishing method.

Over a million metric tons of water was contaminated from contact with fuel rods at Fukushima. Before release, it is filtered using an Advanced Liquid Processing System (ALPS), which removes 62 radionuclides through a series of chemical reactions, according to the IAEA. However, the system is not able to remove tritium, which can only be recovered when it is highly concentrated in small amounts of water.

The contaminated water has previously been treated and stored at the Fukushima Daiichi site, which has roughly 1,000 tanks. However, the volume of water needing to be stored has been increasing, and the tanks are nearing capacity.

To resolve the issue, the water is diluted to one 40th of the concentration permitted by Japanese safety standards, before being released into the sea. The release will occur gradually over the next 30 to 40 years.

Most O&G majors have set net zero targets, but few include Scope 3 emissions

GHG emissions generated by O&G operations accounted for 15% of total energy-related emissions worldwide in 2022. A further 40% of such emissions came from the use of oil and gas for power generation, heating, vehicle fuel, and industrial processes. Only 6 companies have targets covering Scope 3 emissions. To reduce Scope 3 emissions, O&G companies are switching their products to lower-carbon sources of energy including hydrogen, LNG, biofuels, and renewables.
