Noto Peninsula Earthquake and Nuclear Power Plant Risks

１

Many Japanese realized two very lucky factors:
Suzu nuclear power plant was not built
Shika nuclear power plant was not in operation

２

The reality of the destruction of the region
Residents are supported by outside assistanceThis support would be cut off in case of a nuclear disasterNo one to be in charge of nuclear disaster management

３

The need to change nuclear energy policy
Risks from a nuclear disaster as a result of an earthquake
are common to all nuclear power plants

is approximately 1 meter.

Power Plant - Fortunate it wasShut
The tremor, measuring 5+ on the Japanese seismic scale,caused damage and numerous problems at the facility.

If it had been in operation...
Would more difficult tasks such as emergency
shutdown and cooling of the reactors havebeen possible?
Prompt and accurate dissemination ofinformation would be unlikely.

The next major earthquake?
Prof. Shinji Toda,
Tohoku University:
After the Noto Peninsula
earthquake, forces are active
making an earthquake likely tooccur at faults off Sado Islandand offshore and south of theShika Nuclear Power Plant.
(Announced Jan 9)

寺家に原発がなくてよかった(その２)
The next major earthquake?
It indicates that the fault is more likely toshift from off the northeast coast of theNoto Peninsula to off Sado Island and off
the western coast of the Noto Peninsula,
as well as from the Kaga region toToyama Prefecture, meaning thatearthquakes are more likely to occur.

Destruction of the region:
Response is not possible, even with all forces available in the region

Support from all over the country would be
cut off and the entire region be isolated.

gather at an off-site center.

Isolation of the region due to anearthquake from specificcircumstances of a peninsula.
Regional isolation with theaddition of a nuclear disaster is arisk common to all nuclear power
plant locations.

Population north of
Shika Nuclear Power Plant:
approximately 70,000

Approximately 160,000 people within
30 km radius of
Shika Nuclear Power Plant

NRA Chairman Shinsuke Yamanaka
Downplaying Nuclear Disasters
・Will not change basic approach of Nuclear Emergency
Response Guidelines
・Limits discussion to only sheltering in place
・Not looking at reality of destruction of region/community
・Reducing the issue to just the problem of collapsed houses
・Insufficient awareness, especially of local manpower
shortage

In complex disasters,
give priority toresponse to natural
disasters!

Not even able torespond to natural
disasters!!

Need for Change in Nuclear Energy Policy

Earthquake disaster makes selfevacuation difficult
Nuclear disaster makes outside

Residents are trapped and exposed to radiation
Isolation of contaminated areas prolonged,
without reliefEvacuation plans not viable
