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 that
summarizes 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)
On November 9, 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.
(Previously announced on November 9)
Taking into consideration the opinions received in the hearing meetings
held afterwards, we have updated again the contents and reported them to
NISA yesterday.
The government will examine this report hereafter.
Continuously, we will organize 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 in an immediate way.
