The release of a report on the study of six crush zones under the Tsuruga nuclear power plant in Fukui Prefecture has been postponed until the end of January, said plant operator Japan Atomic Power Co.
As instructed by the now-defunct Nuclear and Industrial Safety Agency, the company has been conducting on-site surveys at the plant to determine whether the crush zones have been an active cause of shaking.
The study requires drilling vertical shafts about 30 to 50 meters deep into the ground to study the age and activity of the crush zones.
The findings of the study were due to be released by the end of this month, but the report has been postponed because some drilling and boring jobs have yet to be completed, the company said.
