We received, from Nuclear and Industrial Safety Agency at the Ministry of 
Economy, Trade and Industry, an instruction document* entitled 
"Compatibility for "Policy on the mid term security" concerning the Units 
1 - 4 of Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power 
Company (instruction)" and were instructed* by the Minister of Economy, 
Trade and Industry to report on a plan of how we operate and manage our 
facilities based on the "Policy on the mid term security".
                                        (Previously announced on October 3)

On October 17, based on these instructions, we submitted a report which 
was summarized the contents of the plan concerning the operation and 
management of our facilities written in below and the results of 
evaluations on the security of the facilities to NISA.
· Water injection equipments for Reactor Pressure Vessel / Primary 
  Containment Vessel
· Nitrogen gas injection system for Primary Containment Vessel
· Spent fuel pool etc.
· Boric acid injection system for Reactor Pressure Vessel / Primary 
  Containment Vessel
· Treatment system for high level radioactive contaminated water, 
  Accumulate facilities(tank etc.), Storage facilities for sludge, Storage 
  facilities for used cesium adsorption vessel and concerned facilities
  (transport pipe, transport pump etc.)
· The building which is storing (including accumulating) high level 
  radioactive contaminated water, etc. 
· Power networks
· The Probabilistic Safety Assessment(PSA) about the water injection system 
  for reactor
                                       (Previously announced on October 17)

Today, we have summarized the above-mentioned contents of the plan and the 
result of the evaluation on security, with considering opinions received 
in hearing meetings and reported them to NISA

This report contents will be confirmed by the governments in later.

Continuously, we will summarize the contents of the plan concerning the 
operation and management of other facilities and the results of evaluations 
on the security of the facilities and report to NISA immediately.

                                                                        END
