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.

Instruction to report per Article 67-1 of Act on the Regulation of Nuclear
Source Material, Nuclear Fuel Material and Reactors
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
