Water leaks after new earthquake damage at Fukushima nuclear plant

Strange Sounds – February 20, 2021

Cooling water levels have fallen in two reactors at the wrecked Fukushima nuclear plant since a powerful M7.1 earthquake hit the area last weekend, indicating possible additional damage.

New damage could further complicate the plant’s already difficult decommissioning process, which is expected to take decades.

Tokyo Electric Power Co. spokesman Keisuke Matsuo said the drop in water levels in the Unit 1 and 3 reactors indicates that the existing damage to their primary containment chambers was worsened by Saturday’s magnitude 7.3 quake, allowing more water to leak.

The cooling water level fell as much as 70 centimeters (27 inches) in the primary containment chamber of the Unit 1 reactor and about 30 centimeters (11 inches) in Unit 3. TEPCO wasn’t able to determine any decline in Unit 2 because indicators have been taken out to prepare for the removal of melted debris.

Since the 2011 disaster, cooling water has been escaping constantly from the damaged primary containment vessels into the basements of the reactor buildings. To make up for the loss, additional cooling water has been pumped into the reactors to cool the melted fuel remaining inside them. The recent decline in the water levels indicates that more water than before is leaking out, TEPCO said.

I think this is a no-end disaster! More here.

Dumping Fukushima’s Water into the Ocean What could possibly go wrong?

Robert Hunziker – November 1, 2020

For nearly a decade the crippled Fukushima Daiichi Nuclear Power Plant has been streaming radioactive water into the Pacific Ocean. As it happens, TEPCO (Tokyo Electric Power Co.) struggles to control it. Yet, the bulk of the radioactive water is stored in more than 1,000 water tanks.

Assuredly, Japan’s government has made an informal decision to dump Fukushima Daiichi’s radioactive water into the Pacific Ocean. A formal announcement could come as early as this year. Currently, 1.2 million tonnes of radioactive water is stored.

The problem: TEPCO is running out of storage space.

Government of Japan’s solution: Dump it into the Pacific Ocean.

Third-party expert solutions: Build more storage tanks.

Environmental groups insist there is no reason why additional storage tanks cannot be constructed outside the perimeter of the plant. They accuse the government of seeking the cheapest and quickest solution to the problem. All along, authorities have promised the site will be safe in 40 years. Really, only 40 years!

According to IAEA’s Director General Grossi, who visited Fukushima in February 2020, dumping radioactive water that is mainly contaminated with tritium meets global standards of practice.
