The US Nuclear Regulatory Commission and the Nuclear Energy Institute have been
concerns arising from the World Trade Centre terrorist attack. While it is clear
that US nuclear
power plants are not designed to withstand that kind of impact and fire
unscathed, they are well
designed for lesser impacts and as with most other aspects of their
construction, there is a high
degree of over-engineering. As calculations have been revisited to take account
of a multiple impact
from a heavy aircraft (ie with two or more engines set out from the
energy-absorbing fuselage), it
appears that many reactors are sufficiently robust to survive better than
initially feared. Other security
arrangements at nuclear plants have been re-examined and found credible.
However, in public statements the industry and more explicitly the IAEA did not
rule out the
possibility of damage within the reactor containment from such a suicide attack,
consequent release of radiation. But no informed estimates have suggested that
this would have any
more serious effect than the aircraft impact and fire itself. In other words if
a US nuclear reactor
were selected as a target because of the likelihood of multiplied effects along
the lines of some
Chernobyl scenario, the mission would fail. In fact the containment engineering
and the internal
design of the vast majority of the world's reactors would preclude it, whatever
the damage sustained.
