On June 7, 2011, we received the instruction document*1 from NISA with 
regard to "anti-earthquake countermeasures of the switchyard etc. with a 
view to securing reliability of offsite power supply to Nuclear Power 
Stations etc (instruction)". 
As per the instruction document, we compiled the status of the evaluation 
regarding the possibility of collapse, damage etc. to the electrical 
facilities such as switchyards at our Nuclear Power Station and reported to 
NISA on July 7, 2011. 
                          (Previously announced on June 7 and July 7, 2011) 
 
On January 19, 2012, we received the additional instruction document with 
regard to "anti-earthquake countermeasures of the switchyard etc. with a 
view to securing reliability of offsite power supply to Nuclear Power 
Stations etc (additional instruction)"*2 from NISA . 
(Previously announced on January 19, 2012) 
 
We hereby announce that as per the instruction document we compiled the 
implementation plan for evaluating anti-earthquake countermeasures of the 
switchyards etc. and reported to NISA today. 
Based on this implementation plan, we will make evaluations and implement 
the measure based on the evaluation results. 
 
                                                                       END

Implementation plan to evaluate anti-evaluation plan to secure reliability 
of offsite power supply to Nuclear Power Stations 
 
*1 Instruction document 
"Anti-earthquake Countermeasures of the Switchyard etc. With a View to 
Securing Reliability of Offsite Power Supply to Nuclear Power Stations etc 
(instruction)" 
                                                      (06.07.2011 NA No. 1) 
 
The Nuclear and Industrial Safety Agency ("NISA") received from General 
Electricity Utilities, etc., the reports on May 16, 2011 related to NISA's 
directions in the 04.15.2011 NA No. 3 dated April 15, 2011 regarding the 
securing reliability of external power supply for nuclear power stations 
and reprocessing facilities ("NPS, etc."). Today, NISA conducted evaluation 
of the subject reports. 
In addition, NISA received a report from the Tokyo Electric Power Co. Inc 
("TEPCO") on May 23, 2011 regarding the cause for the damage related to the 
electric equipment inside and outside Fukushima Dai-ichi Nuclear Power 
Station ("NPS") according to the 05.16.2011 NA No. 3 dated May 16, 2011. 
According to this report, the circuit breakers, etc., were damaged at the 
switching yards related to Units 1 and 2 of the Fukushima Dai-ichi NPS due 
to the earthquake. 
Considering the above assessments and reports, NISA requests General 
Electricity Utilities, etc., to implement the following items from the 
perspective of securing reliable external power supply. Moreover, NISA 
requests submission of reports regarding the state of implementation for 
these measures by July 7, 2011. 
 
Required Items 
 
1.Assess the impact of the possibility for the occurrence of equipment 
  falling over or damage, etc. causing malfunctions in the electric 
  equipment of the switching yards, etc. at General Electricity Utilities' 
  NPS, etc., in consideration of the analysis results of the earthquake 
  records observed at TEPCO's Fukushima Dai-ichi NPS due to the 2011 Off 
  the Pacific Coast of Tohoku Earthquake. 
  As an aside, for these assessments, setting for the seismic force at each 
  NPS, etc. at the surface level as a standard related to the switching 
  yards, etc., analyze the stress occurring at the electric equipment, and 
  evaluate it by comparison with the structural strength of the subject 
  electric equipment. 
2.If by the assessment in above-described 1, it is determined that a 
  possibility for the occurrence of equipment falling over or damage, etc. 
  causing malfunctions exists, decide the countermeasures against 
  earthquakes for the subject electric equipment.
