Radioactive steam detected at Onagawa: reactor two to undergo inspection

Published on May 17, 2026 | Translated from Spanish

Reactor number 2 at the Onagawa nuclear power plant will be shut down for a preventive inspection after the detection of radioactive steam in the turbine building. Measurements indicate that the radioactivity in the accumulated water is one-thousandth of the government notification threshold, prompting a safety review to rule out possible leaks in the system.

Low radiation but mandatory technical review 🛠️

Although the detected radioactivity levels are minimal, authorities have opted for a technical shutdown to verify the integrity of the pipes and valves in the turbine system. The inspection will include corrosion analysis and pressure tests on the affected components. This standard procedure aims to ensure that no microcracks exist that could evolve into larger leaks, following nuclear safety protocols established after Fukushima.

Steam that scares no one, but stops the reactor 😅

The Onagawa plant has decided to take a forced vacation because its turbine water decided to emit a slight radioactive sigh. With levels a thousand times below the legal limit, rather than a leak, it seems the reactor had a stress attack and asked for a checkup. Meanwhile, workers will look for whether the ghost of Chernobyl left any prank note in the pipes.
