Following the shutdown of all of Japan's reactors after the March 2011 accident at the Fukushima Daiichi plant, Ohi 3 and 4 were given permission to resume operation in August 2012. However, the two 1180 MWe pressurised water reactors (PWRs) were taken offline again for Nuclear Regulation Authority (NRA) inspections in September 2013.

The NRA announced in May 2017 that the two units meet safety standards introduced in July 2013. The NRA approved Kansai's plan for strengthening the units in August last year. The regulator subsequently conducted pre-operation inspections of the units to confirm that the safety countermeasure equipment complies with the approved construction plan at the plant. The governor of Fukui Prefecture approved the restart of Ohi units 3 and 4 in November.

Kansai began loading the 193 fuel assemblies into the core of unit 3 on 9 February, completing the process on 13 February. The reactor was restarted at 5.00pm yesterday. Kansai said Ohi 3 attained criticality - a sustained chain reaction - at 3.00am today.

On 13 March, Kansai said: "After reaching criticality, the plant will start power control operation on 16 March 2018 as the final stage of the periodic outage inspection following various types of tests." It added, "In early April, the plant will restart full-scale operation after the completion of the comprehensive inspection performed by the Nuclear Regulation Authority."

Kansai earlier said it expects to refuel Ohi 4 in mid-April, restart it around mid-May, with commercial operation expected to resume in early June.

While looking at the Japan radiation readings today, I notice elevated reading in the area of the Ohi Nuclear Plant and it seems to fall around the timeline mentioned in the news article for refueling. We know that during a refueling process the reactor is opened and vented. It is my understanding that during a refueling process the largest amount of legally allowed radioactive releases are made.

Here is a screenshot of the NETC map showing the elevated readings.
