    TOKYO, Jan 13 (Reuters) - Japan's Kyushu Electric Power
 has restarted the No. 2 reactor at its Sendai nuclear
plant in southwestern Japan after completing mandatory upgrades
to protect the facility against terrorist attacks, a spokesman
said.
    The utility began booting up the 890-megawatt (MW) reactor
on Dec. 22 after also carrying out regular maintenance and
refuelling, the spokesman said by phone on Wednesday. 
    With the restart, Japan now has three operating nuclear
reactors with a total capacity of 2,960 MW. Many reactors are
still going through a re-licensing process under new safety
standards imposed after the 2011 Fukushima disaster.
    Nine regional power utilities and a wholesaler, Japan Atomic
Power Co (Japco), now have 33 reactors available for commercial
use, with a combined generating capacity of 33,083 MW. The
companies had 54 reactors operating before the Fukushima
disaster.
    The table below shows the status of Japan's nuclear power
plants. The regional utilities are Hokkaido Electric Power
, Tohoku Electric Power, Tokyo Electric Power
, Chubu Electric Power, Hokuriku Electric Power
, Kansai Electric Power, Chugoku Electric Power
, Shikoku Electric Power, Kyushu Electric Power
, referred in the table by their regional name.
