Ad15 Particularly in March, it was confirmed that six people exceeded
250 mSv, which is the dose limit for an emergency worker. All
these were TEPCO employees who were operators and
engineers in electricity and instrumentation engaged in monitori
of instruments in the main control rooms immediately after the
occurrence of the accident. TEPCO has made it a rule not to
allow workers who have exceeded 200 mSv to work at the
Fukushima Dai-ichi NPS. p. 15 summary
Ad7 Although cooling by isolation condenser (IC) (two lines) was
begun after the automatic shutdown of the nuclear rector, it

Summary
D102 The secretariat of the NERHQ, which should have played a
active role in the decision-making on evacuation zones, was
able to make a proposal of any kind to the fifth floor of the
Kantei. They accepted the evacuation orders that had been
unilaterally decided upon at the fifth floor of the Kantei, with
understanding of the grounds for such orders. (C3 pg 63)
D103 Questions also remain over whether or not they possessed th
required know-how for allocating human resources to the
emergency response. (C1 pg68)

At the time of the accident, however, TEPCO had not comple
the seismic backchecks, and the final report was scheduled for
submission in January 2016. This is approximately one decade
after the 2006 seismic backcheck instructions and 21 years after
the Great Hanshin-Awaji Earthquake that became the
catalyst for revising the Guideline.
