Press Release (May 16,2011)
Submission of a report regarding the plant data of Fukushima Daiichi Nuclear Power Station at the time of the earthquake to Nuclear and Industrial Safety Agency, Ministry of Economy, Trade and Industry
On April 25th, 2011, we received an instruction notice from Nuclear and 
Industrial Safety Agency (NISA), Ministry of Economy, Trade and Industry 
per Article 67-1 of Act on the Regulation of Nuclear Source Material, 
Nuclear Fuel Material and Reactors.
                                           (Announced on April 26th, 2011)

As per the instruction notice, we collected as much plant data as possible 
at the time of the earthquake, sorted and reported to NISA today.

Also, as it was confirmed that part of plant parameters of Fukushima 
Daiichi Nuclear Power Station posted to our website from April 18th, 2011 
were incorrect, we verified data including the other part, compiled and 
reported to NISA.

                                                    No.1: April 24th, 2011
                                                          April 25th, 2011

Taking into consideration the roadmap towards restoration from the 
accident at Fukushima Daiichi Nuclear Power Station which you have 
formulated, we hereby instruct you per Article 67-1 of Act on the 
Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors 
(Act No. 166 of 1957) to report the following items in a rapid manner in 
order to take the appropriate emergency steps from here on. 

In addition, you must ensure that the workers are not exposed to more than 
the minimum designated amount of radiation while collecting the materials. 
In case it is expected that prompt reporting will be difficult due to 
certain circumstances such as the materials to be reported are in areas 
where the air is filled with highly concentrated radioactive materials and 
are therefore hard to collect, it must be verified how the materials are 
being presently being stored, prospects concerning the expected timing of 
the report, and any other related and necessary conditions and report the 
results in a rapid manner.  
 
If you disagree with this disposition, you may raise an objection with the 
Minister of Economy, Trade and Industry within sixty days from the day 
following the date when you learnt that the disposition was made under 
Article 6 of Administrative Dissatisfaction Inspection Act (Act No. 160 of 
1962). However, you may not raise an objection after one year has passed 
since the day following the date of the disposition even if it falls 
within sixty days from the day following the date when you learnt that the 
disposition was made.

Based on provision Administrative Case Litigation Act (Act No. 139 of 
1962), you may file an action for cancellation of the disposition against 
the national government (representative; the Minister of Justice) after a 
decision is made on the aforementioned objection, within six months from 
the day following the date when you learnt that the decision was made. 

However, you may not file an action for cancellation after one year has 
passed since the day following the date of the decision on the objection 
even if it falls within sixty days from the day following the date when 
you learnt that the decision was made.

If one of the following events happens, you may file an action for 
cancellation of the disposition without having to wait for a decision on 
the aforementioned objection: (i) no decision has been made even after 
three months have passed since the day following the date when you raised 
the objection, (ii) there is an urgent necessity in order to avoid any 
considerable damage that would be caused by the original administrative 
disposition, the execution of the original administrative disposition or 
the continuation of any subsequent procedure, and (iii) there are any 
other justifiable grounds not to obtain an administrative decision.

○You have to report the following items among the operation records 
  (including the ones that are made immediately after the occurrence of 
  the Tohoku-Chihou-Taiheiyou-Oki-Earthquake in 2011) prescribed in 
  Article 7-1 of Regulations Concerning the Installment, Operation, etc. 
  of Practical Generation Reactors (The Ministry of International Trade 
  and Industry Order No. 77 of 1978) and accident records of the nuclear 
  reactor facilities etc. in connection with this accident
