(1) A provision or endorsement found in or attached to virtually all property
policies (other than the specialty policies designed to cover loss as a result
of nuclear radiation). Eliminates coverage for loss or damage from nuclear
reaction or radiation or radioactive contamination, except that ensuing fire is
explicitly covered. (2) A provision or endorsement found in or attached to
virtually all commercial lines liability policies. The standard broad form
nuclear energy exclusion most often attached to liability policies (IL 00 21)
precludes coverage only for liability insured under a nuclear energy liability
policy or for which indemnity is available from the U.S. government. The
exclusion does not normally apply to liability arising from radioactive
isotopes, the most common commercially used nuclear materials.
