Cover images: (Front) Satellite image of the Fukushima Daiichi Nuclear Power
Station taken on March 14, 2011, while the accident was still in progress. The
Unit 1 reactor building (lower-left corner of image) was damaged by a hydrogen
explosion at 15:36 (3:36 P.M.) Japan Standard Time on March 12. The Unit 3
reactor building (building with steam plume near center of image) was damaged by
a hydrogen explosion at 11:01 the day the image was recorded. The Unit 4 reactor
building, which is still intact in this image, would be damaged by a hydrogen explo-
sion at 06:14 the next day (March 15). (Back) Satellite image of the harbor-front of

Lessons Learned from the Fukushima Nuclear Accident for Improving Safety of U.S. Nuclear Plants
The National Academy of Sciences is a private, nonprofit, self-perpetuating society
of distinguished scholars engaged in scientific and engineering research, dedicated to
the furtherance of science and technology and to their use for the general welfare.
Upon the authority of the charter granted to it by the Congress in 1863, the Acad-
emy has a mandate that requires it to advise the federal government on scientific
and technical matters. Dr. Ralph J. Cicerone is president of the National Academy
of Sciences.
The National Academy of Engineering was established in 1964, under the charter
of the National Academy of Sciences, as a parallel organization of outstanding
engineers. It is autonomous in its administration and in the selection of its members,
sharing with the National Academy of Sciences the responsibility for advising the
federal government. The National Academy of Engineering also sponsors engineer-
ing programs aimed at meeting national needs, encourages education and research,
and recognizes the superior achievements of engineers. Dr. C. D. Mote, Jr., is presi-
dent of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of
Sciences to secure the services of eminent members of appropriate professions in
the examination of policy matters pertaining to the health of the public. The Insti-
tute acts under the responsibility given to the National Academy of Sciences by its
congressional charter to be an adviser to the federal government and, upon its own
initiative, to identify issues of medical care, research, and education. Dr. Victor J.
Dzau is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sci-
ences in 1916 to associate the broad community of science and technology with the
Academy’s purposes of furthering knowledge and advising the federal government.
Functioning in accordance with general policies determined by the Academy, the
Council has become the principal operating agency of both the National Academy
of Sciences and the National Academy of Engineering in providing services to
the government, the public, and the scientific and engineering communities. The
Council is administered jointly by both Academies and the Institute of Medicine.
Dr. Ralph J. Cicerone and Dr. C. D. Mote, Jr., are chair and vice chair, respectively,
of the National Research Council.
