Japan Halts Onagawa Reactor After Radioactive Steam Detected for Inspection

The operator of the Onagawa nuclear power station in Miyagi Prefecture, Japan, announced it will halt the No. 2 reactor after detecting a small amount of radioactive steam in its turbine building. No radioactive materials leaked into the environment, and the shutdown is for inspection. The incident is unrelated to a recent 6.4-magnitude earthquake. The reactor had recently resumed operation following a regular inspection. Separately, a steam leak at the Mihama nuclear plant's No. 3 reactor in Fukui Prefecture led to a manual shutdown, with no radioactive release reported.
