 REPORT BY THE U.S.

 General Accounting Office








 Response To Specific

Questions On The Indian Point

Probabilistic Safety Study


This report describes and summarizes how
probabilistic risk assessment (PRA) is applied
to nuclear powerplants, the methodology
and results of a PRA on the Indian Point
plants near New York City, and peer review
comments on that study.

PRAs attempt to examine complex systems,
such as nuclear powerplants, and identify
their potential safety, environmental, and
economic risks. GAO found that while the
Indian Point PRA may represent the state of
the art in risk assessment, it suffers from
the same limitations as all PRAs: uncertain-
ties and inconsistencies in data, models,
assumptions, and methods. Although the
study identified the dominant contributors
to risk, it did not identify the precise level of
risk from operating the Indian Point nuclear
powerplants
