February 1997- Train in France
derails with deadly spent nuclear fuel on board.
SPENT
FUEL QUICK FACTS:
The following information is
provided by the Nuclear Information and
Resource Service,
Radioactive Waste Project, 1424
16th Street NW, #601, Washington, DC 20036
Note: These facts were prepared
for the proposed Yucca Mountain Dump in Nevada, however the essential facts
also apply to the proposed Goshute facility.
As many as 15,000 shipments
to Utah would be made over the next 30 years. Each
large train cask carries the long-lived radiological equivalent of 200
Hiroshima bombs. In terms of radioactivity, each fuel assembly contains
10 times the long-lived radioactivity released by the Hiroshima bomb.
A person standing three feet
from unshielded irradiated fuel would receive a lethal
radiation dose in 10 seconds.
Current
cask fire standards do not reflect the possibility of a tanker fuel fire.
A fire associated with a truck or rail accident increases the probability
that radioactivity will be released. Fires occur in 1.6% of all truck and
1% of all train accidents. Shipping containers are designed to withstand
a 1/2-hour fire at a temperature of 1475 Fahrenheit. But rail fires could
burn for hours, sometimes for days, at temperatures considerably higher.
Diesel fuel burns at 1850 Fahrenheit. Some materials burn twice as hot.
The heat could vaporize some radioactive materials and sweep them up into
the air. Persons downwind could inhale radioactive particulates and later
develop cancer or genetic effects. (On July 2, 1997 a collision between
two trains in Kansas produced just such an intense diesel fire.)
Accidents will happen -- the
Department
of Energy expects at least 15 truck accidents yearly!
New cask designs are more than
twice as large as any cask used before, and they will be tested only by
computer models, not under actual accident conditions.
Existing transport routes are
designed for commerce and link major population centers; they are
not designed for radioactive waste transportation.
About 3/4 of the U.S. population
could be affected by these shipments.
Shipping containers are designed
to withstand a crash into an immovable object at 30 miles per hour. Obviously
Interstate trucks travel much faster than 30 m.p.h. Impact into a bridge
abutment or falls off a bridge could easily exceed the design limits of
the container.
None of
the containers presently used on highways and rails has been physically
tested. These containers were designed and built in the 1960's and
'70's. Waste containers have only been tested by computer or hand calculators.
Before the flood gates open on nuclear shipments, the Department of Energy
should at least require that the new generation of shipping containers
presently proposed be actually physically tested, but the Department has
no such plans.
NOTE: There is a very
real prospect of nuclear sabotage and terrorism
happening to these shipments. The bombings at the World Trade Center, Oklahoma
City Federal Building, and the Atlanta Olympics point to this threat. What
if an act of nuclear terrorism occurred during the to one of the 9 or 10
shipments of high-level nuclear spent fuel that will travel through Salt
Lake City each day?
