Preface
This document is a summary of the outline of the safety regulation
administration of nuclear facilities as well as various data on the commercial
nuclear power reactor facilities, research and development nuclear power
reactor facilities, fabrication facilities, reprocessing facilities, and disposal
facilities in fiscal year 2009 (from April 2009 to March 2010). We sincerely
hope this document is used widely by many people engaged in work related
to ensuring nuclear safety.

-1 Status of Operation, Construction and Decommissioning of
Nuclear Power Plants
(1) Commercial power reactor facilities
As of the end of FY2009, the number of units in operation at nuclearelectric power plants were 54 with their total output 48,847,000 kW.Hamaoka Nuclear Power Station, Units 1 (540,000 kW: BWR) and
2 (840,000 kW: BWR) were legally closed on January 30, 2009 and havebeen in the decommissioning stage since FY2009
The Japan Atomic Power Company's Tokai Power Station (166,000 kW:GCR) discontinued commercial operations at the end of FY1997 and hasbeen in the decommissioning stage since FY2001.

-1 General situation
At the end of FY2009, the capacity factor of nuclear power stations for electric power industry in Japan was
65.7% on average for all nuclear power stations in operation (54 units with a total power generating capacity of
48,847,000 kW).

Number of units 30 24 54
Power (10 MW) 2,856.9 2,027.8 4,884.7
Capacity factor (%) 55.5 80.6 65.7
Looking at the operational status of plants in Japan in FY2009, the total capacity factor was 65.7%, exceeding the
60.0% of the previous year.
Considering reactor types, the capacity factor of BWRs was 55.5%, exceeding the 51.1% of the previous year. The
major cause of this rise was increased power generation due to resumption of Kashiwazaki Nuclear Power Station
Units 6 and 7, and Shika Nuclear Power Station Unit 1.The capacity factor of PWRs was 80.6%, exceeding the 73.7% of the previous year. The major cause of this rise
was increased power generation due to operation at rated thermal output, even although the hourly operating rate
fell under the planned value.

The capacity factor, operation factor, generated power, etc. of nuclear power stations in Japan are summarized
in the following pages.
Please note that generated power is expressed by using the output at the generating end (gross).

Operating time of reactor is the time between the startup and shutdown of the reactor.
(4) The electric power generation and generation time in the fiscal year and month of startup are counted from
00:00 am on the commercial operation starting date.
(5) The capacity factor and operation factor in the fiscal year and month of startup are counted according to
calendar time from the commercial operation starting date.
(6) The total and subtotal by licensee and the sum total after startup are the summation of generated power
(minimum unit is MWh) and time (minimum unit is hour before FY1995, and minute after FY1996) for
each fiscal year and each unit.
(7) The Japan Atomic Power Company, Tokai Power Station finished commercial operation at the end of
FY1997 and has been in the decommissioning stage.
(8) Chubu Electric Power Company, Hamaoka Nuclear Power Station, Units 1 and 2 were legally closed on
January 30, 2009.
(9) The licensed power generation of Japan Atomic Power Company, Tsuruga Power Station, Unit 1 was
changed from 331 MW to 357 MW on December 15, 1970.
(10) The licensed power generation of Chubu Electric Power Company, Hamaoka Nuclear Power Station, Unit 5
was changed from 1,380 MW to 1,267 MW on March 13, 2007.
(11) The licensed power generation of Hokuriku Electric Power Company, Shika Nuclear Power Station, Unit 2was changed from 1,358 MW to 1,206 MW on June 5, 2008.
