IKATA, Ehime — Water containing radioactive materials has leaked from a purification system inside of a stalled nuclear reactor here, Shikoku Electric Power Co. and the Ehime Prefectural Government announced on May 9.
The leak occurred in the auxiliary building of the No. 3 reactor at the Ikata Nuclear Power Station in the town of Ikata, Ehime Prefecture. According to the prefectural government and Shikoku Electric, the coolant water was found to be leaking from the pressure gauge stop valve for the purification system at around 2:10 a.m. on May 9.
The radiation level of the materials in the roughly 130 milliliters of escaped water measured 20 becquerels, far below the standard for filing a report to the central government. The utility and Ehime Prefecture said there is no reported leakage outside of the facility, nor was there any danger posed to employees or the surrounding environment. Regardless, the reason for the leak will be investigated thoroughly.
The No. 3 Reactor at the facility was restarted in August 2016. However, while the rector was undergoing a scheduled inspection in December 2017, a temporary injunction was handed down by the Hiroshima High Court that halted operation at the site.
