On August 23, 2011, we are going to commence the 10th regular inspection 
for Unit 7 of Kashiwazaki Kariwa Nuclear Power Station (advanced boiling 
water reactor type, 1,356 MW of rated output). The details are shown below. 

1.Planned working period for the inspection
  From August 23rd, 2011 (83 days)

2.Main equipment that will be inspected
  (1) Reactor 
  (2) Reactor cooling system facility
  (3) Instrumentation and control system facility
  (4) Fuel facility
  (5) Radiation control facility
  (6) Disposal facility 
  (7) Primary containment facility
  (8) Emergency reserve generation facility
  (9) Steam turbine

3.Planned main works during the regular inspection
  (1) Replacement of fuel assemblies
      200 out of 872 fuel assemblies will be replaced.

  (2) Replacement of control rods
      25 hafnium flat tube-type control rods out of 205 control rods will 
      be replaced by boron carbide type control rods.

  (3) Replacement of clean up water system pipes 
      New ventilation pipes that exhaust mixed gas (hydrogen and oxygen) 
      generated through radiation dissolution in the reactor will be 
      installed to clean up water system pipes to prevent the gas from 
      accumulation.

  (4) Countermeasures against tsunami
      The following equipment will be arranged or installed for the 
      countermeasures against tsunami
      -Laying out cables from emergency high voltage distribution boards to 
       the that in the reactor building
      -Arranging alternative seawater heat exchange equipment 
      -Installing top ventilation equipment in the reactor building

4.Others
  We will identify the fuel assembly where a pinhole, through which 
  radioactive materials in the form of gas leaked into the reactor coolant, 
  on a cladding tube of a fuel rod was potentially created.
  We will conduct the shipping inspection to all the fuel assemblies, then 
  conduct visual check the whole of the identified fuel assembly using the 
  underwater camera as well as ultrasound scan to identify the leaking fuel 
  rod. We will observe it in details using the fiber scope.

  During this regular inspection, we will clean up the reactor and systems 
  connecting to the reactor to further reduce the leaked fuel.

  With respect to the start-up, we will consult the national and local 
  government adequately and deliberately.

                                                                       END
