safe are our
looked into the question. good morning.
good morning. nuclear regulators say u.s.
nuclear power plants
are built to with stand significant earthquakes and tsunamis and that current safeguards are adequate to protect the public. but the japanese officials would have said the seem thing a week ago. some scientists warn what's happening in
could happen here. this was not supposed to happen. a number of japanese reactors out of control, the threat of a nuclearle me meltdown. in the u.s. there are 104 nuclear
which provide 20% of electricity here. edward limon says this shows
should be raised across the board. could what happened in
yes. i'm afraid it could. unless we learn the lessons of this accident it's only a matter of time.
issue one, earthquakes. some
are located in or near areas of seismic risk. the greatest hazards, the areas in red. u.s.
are required to be able to with stand the worst earthquake expected in their area. plus a margin of safety. two california plants are in earthquake-prone areas,
built to with stand a 7.5 magnitude quake and, designed to with stand a 7.0,
's was a 9.0.
we need to consider the possibility of greater magnitude earthquakes than we had previously considered.
issue two, plant design. this is a design of the reactor in
there are 31 plants in the u.s. similar to those in trouble in
, designed by
which is a part owner of
in new jersey, is the oldest
in the country, about 50 miles from new
. issue three,
systems. experts say the japanese reactors basically got into trouble because they lost electricity and
systems failed, too, leaving them struggling to cool the
. marvin fertell of the
says thanks to improvements since 9/11, u.s. plants have more ability to cope if power is lost.
we would be able to handle the situation much easier than the japanese are facing now.
could what happened in
could we have an event that -- we think -- i would say it's highly improbable it could happen here. if it did, i think we would handle it quite well here.
called for a moratorium on building new reactors in earthquake-prone areas of this country until a sweeping safety review is conducted of exactly what went wrong in
for us in washington, thank you very much. it's 34 after the hour.
