The Three Mile Island

Nuclear Accident:

GAO's Role


James E. Hatcher
Mr Hatcher a management analyst on the
nuclear staff of the Energy and Minerals
Division joined GAO in 1969 after working
for the CPA firm of Ernst & Ernst He re-
ceived a B S degree in business ad-
ministration from Concord College, Athens.
West Virginia and has done graduate work
at George Washington University and Mt
Saint Mary s College He has been auditing
iuctear-related activities for the past
vears


   Near 4:00 a.m. on Wednesday,
 March 28, 1979, an event occurred
 which triggered the worst accident
 in the history of commerical nu-
 clear power. Through a combina-
 tion of equipment malfunctions
 and plant operator error, the core
 of a nuclear reactor was voided of
 cooling water long enough to
 cause serious damage. Large
 amounts of radioactive materials
 and gases escaped from the core
 into the reactor system and sub-
 sequently into the massive con-
 crete containment building sur-
 rounding the reactor. Because the
 containment building was not im-
 mediately isolated from the rest of
 the plant, contaminated water was
 pumped into another, less secure
 building where unknown amounts
 of radioactivity escaped into the
environment.
  While these environmental re-
leases were not believed to have


been significant, much confusion
existed at the time of the accident.
It was clear that the plant operators
and owners, the nuclear industry,
and the State and Federal Govern-
ments did not fully understand and
were not prepared to deal with the
events as they happened. This has
rekindled serious questions about
the safety of nuclear power and
has threatened to reduce further
the potential of nuclear ower in
the energy future of the United
States.
How a Ractor
Operates
  A nuclear reactor is, simply
stated, a sophisticated machine
which produces the steam used to
drive a turbine and produce electri-
city. It is comparable to the boiler
in a coal or oil-fired powerplant.
The particular reactor at Three Mile
Island is called a pressurized,
