Press Release (Jan 16,2012)
Report of Results of Comprehensive Evaluation (Primary Evaluation) regarding Safety on Unit 1 and Unit 7 of Kashiwazaki-Kariwa Nuclear Power Station to NISA
On July 22, 2011, we received an instruction document titled, "Comprehensive 
Evaluation of Existing Nuclear Power Reactor Facilities after the Accident 
at Fukushima Daiichi Nuclear Power Station, Tokyo Electric Power Co., Inc., 
(Instruction)*" from Nuclear and Industrial Safety Agency (NISA) of Ministry 
of Economy, Trade and Industry (METI). 
                                                (Announced on July 22, 2011) 

Based on the instruction, we made a comprehensive safety evaluation (primary 
evaluation) on Unit 1 and Unit 7 of Kashiwazaki-Kariwa Nuclear Power Station,  
and reported the results to NISA of METI. 

In the results, we evaluated that Unit 1 and Unit 7 of Kashiwazaki-Kariwa 
Nuclear Power Station secured safety with some margin against earthquake 
and tsunami which exceed assumption in the design. Besides, we confirmed 
that the safety margin further improved by the emergency safety 
countermeasures and the further safety measures.  

We continuously make efforts to take safety countermeasures of nuclear power  
station. When we confirm new findings through the analysis of cause on the  
accident of Fukushima Daiichi Nuclear Power Station and the evaluation 
process, we will take appropriate measures based on such findings and keep 
safety security of nuclear power station. 

                                                                       End
