  Nonconformances Found in the Inspection and Restoration Works Performed after the 
  Niigata-Chuetsu-Oki Earthquake

  Based on the "Public Announcement Regarding Nonconformance Found in the Inspection 
  and Restoration Works Performed after the Niigata-Chuetsu-Oki Earthquake", the Tokyo 
  Electric Power Company, Incorporated (TEPCO) provides this announcement containing 
  incidents information reported from January 8th to January 14th, 2009. 

 ○ Incidents Information (relating to the Chuetsu-Oki Earthquake)  
  < Reports from January 8 to January 14, 2009 >  
 ○ Other Findings

  • Information on Nonconformances (those related to: the Chuetsu-Oki Earthquake; 
    Grades As, A, B, C, D; and non-graded)       * Numbers were corrected to reflect nonconformance incidents that had been 
        identified as not related to the Chuetsu-Oki Earthquake (7 cases) and that 
        had been double-counted (1 case). 

  • We sincerely acknowledge the instructions and requests from various institutions and 
    will do our best to prevent recurrence of events by increasing the level of safety 
    consciousness together with cooperating companies. 
    We sincerely apologize for causing anxiety to local residents due to the fires that 
    broke out at the turbine building of TEPCO's Kashiwazaki-Kariwa NPS Unit No.7 on 
    November 22nd, 2008 and at the turbine building of Unit No.6 on December 8th, 2008.
    As for these two fires, we have reported the root cause analysis and recurrence 
    prevention measures of each case to the Nuclear and Industrial Safety Agency (NISA) 
    of the Ministry of Economy, Trade and Industry, and we are earnestly carrying out 
    this recurrence prevention measures. 
    We sincerely acknowledge the instructions and requests from various institutions and 
    will do our best to prevent recurrence of events by increasing the level of safety 
    consciousness together with cooperating companies. 

  • The number 3 solid waste storage building that begun construction on April 2008 was 
    completed on December 25th, 2008 and was designated as radiation protection area on 
    January 13th, 2009. 
    The construction of the number 3 building had been planned prior to the occurrence of 
    the Niigata Chuetsu-Oki earthquake with the intention to expand the storage capacity 
    of drums up to a total of 45,000 permitted by the regulatory agency at the time of 
    the establishment permit of the Kashiwazaki Kariwa NPS. 
    By the end of 2006, the number of drums had reached 21,700 or 70% of the total storage 
    capacity of 30,000 of the existing storage buildings number 1 and 2. 
    With the completion of building number 3, a total of 45,000 drums can now be stored 
    at the site. 
    Based on a study of storage method of drums that is resistant to seismic motion, we 
    have decided to use rack-type storage containers in addition to box pallets currently 
    used in the interim storage facility. 
    We plan to relocate currently stored drums and newly generated drums to box pallets 
    and rack-type storage containers in the next 1 year.
