概要
A shatter zone called “D-1” exists in site of Tsuruga Power Station. The Japan Atomic Power Company has been nvestigating and evaluating the D-1 shatter zone since the construction period of Tsuruga Power Station Uni t-2. In addition, in the D-1 trench to evaluate the activity of the D-1 shatter zone, two faults of the G fa t and the K fault was confirmed. The G fault continues to the D-1 shatter zone. K fault does not continue t the D-1 shatter zone. The results of an investigation of the D-1 trench indicate that the G fault had not be en active since the middle Pleistocene or before at least. That is, the D-1 shatter zone including the G fau does not correspond to “faults that may be active in the future”. In addition, the K fault which does not c ontinue to the D-1 shatter zone does not correspond to “faults that may be active in the future” similarly.
