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.

-5 Installed Capacity of Nuclear Power Plants

Japan's nuclear electric power plants have an installed capacity of 54units and 48,847,000 kW as of the end of FY2009, as shown in Table I-1.The number of units accounts for 20.2% of all power generating facilitiesoperated to supply general electricity, while the electric energy generated

accounts for 29.3% of the total electric energy produced annually.

-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).

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.
