• The building cover has been installed to prevent dispersion of radioactive materials.• Now the cover was dismantled in preparation for the fuel removal operation.

• Currently, toward the fuel removal from SFP, removal of rubbles is underway.• On August 2, 2015, removal of largest rubble(FHM), weighs close to 20 tons, lying in 

the spent fuel pool was completed by remote control .

• On December 22, 2014, all (1533) fuel removal from Unit 4 SFP was completed.

2. Nuclear Energy Policy of Japan

Nuclear Policy : Dependence on Nuclear Power

○ Prime Minister Abe’s direction to Minister of Economy, Trade and Industry (January 25, 2013)・To review from scratch “Innovative Strategy for Energy and the Environment” decided by the former administration and to establish a robust and responsible energy policy from various perspectives, including stable supply of energy, reduction of energy cost.

<Former Administration’s Statement>○ “Innovative Strategy for Energy and the Environment” (September14, 2012)1. Realization of a Society Not Dependent on Nuclear Power in Earliest Possible Future.・Japanese Government will mobilize all possible policy resources to such a level as to even enable zero operation of nuclear power plants in the 2030’s.

Considering the unique energy situation of Japan :

Nuclear Power is positionedas an important base-load power source

The Government of Japan stated that nuclear power is an important base-load power source as a low carbon and quasi-domestic energy source, contributing to stability of energy supply-demand structure.

The Government of Japan will proceed with the restart of NPPs, in case that the NRA confirms the conformity of nuclear power plants with the new regulatory requirements.

• The Hiroshima High Court revoked a lower court decision and ordered the suspension of a nuclear reactor at Shikoku Electric Power Co.’s Ikata NPP

The high court suspension order mandates that the plant operator shutter the No. 3 unit at the Ikata power plant until the end of September.

The ruling blocks the planned resumption in January of the unit, which is currently offline for regular checks after it was restarted in August 2016.

Shikoku Electric said the court’s decision is “unacceptable” and plans to file an appeal.

The court questioned a decision by the Nuclear Regulation Authority that potential risks associated with volcanic eruptions would not breach the stricter regulations introduced following the 2011 Fukushima nuclear crisis.
