ownded Fukushima Daiichi and Daini power plants
said no to help from America as they believed they could contain the issue
stubborn?
NISA
nuclear regulator
contracted/plant workers
taken to hospital on 24th march due to beta-radiation burns on legs
ignored radiation readings and continued to traed in contaminated water
believed the reader was broken
radiation exposure
problems in reactors with leakages
hydrogen explosions
Management
Job Design
location was not taken into account
11km off the coast
more land space
away from major cities
resourcing
Japan officials turned down help from America in cooling to power plants
believed they could control it themselves
Information Transfer
Anti-seismic back check was not completed on time due to CISA not pushing the TEPCO.
report was due to be released in April 2011
NISA ignored countermeasures
Workplace
Workplace Factors
Site design was not thought through
made too low to sea level
poor researching
fixed plant design
AC power source shortages
no action was taken to fix
DC power source had poor reliability
no action was taken to fix
Geotech Designing
in the case of a tsunami, the core would malfunction (assumed by the Society of Civil Engineering)
Equipment design
plant not made above required sea level
poor research
relying on data from 1960
made 10m above sea level even though NISA was informed of previous tsunamis reaching 14.4m
height warnings ignored
did not move the back up generators to higher ground
no sealing of lower parts of buildings
seawater pumping backups were not moved to higher ground
