Japanese Nuclear Power station availability is about 60%

The quote of the day is

"The availability of 55 Unit Japanese Nuclear Power station (49,470MW) is about 60% according to the database of Ministry of Economy, Trade and Industry.--- The availability of Nuclear station in France and in the USA Nuclear advanced country is about 90%." (p131)

Why are Japanese Nuclear Power stations forced outage ratio 4 times larger than that of other countries. One of the reasons is that Kashiwazaki Nuclear Power station(6,400MW) was recently stopped by the big earthquake, and another reasons are Nuclear Power Station is easily stopped by a minor incidents, a long recovery time, and a fixed long duration of overhaul maintenance.

Government officials from the Ministry of Economy, Trade and Industry stay in all Nuclear Power stations and they are monitoring activities of the electric company. That makes us confident, but causes the availability worse.

It is a big problem that it cost over million dollars to stop a nuclear power station for a day because fossil fuel-burning stations use more expensive fuel to recover.
