Update of Ulysses FSAR results using updated NASA (National Aeronautics and Space Administration) probabilities

The mission risk results reported in the Ulysses Final Safety Analysis Report (FSAR) issued on March 14, 1990, were based on initiating accident probabilities the National Aeronautics and Space Administration (NASA) provided to the Department of Energy (DOE) on July 13, 1988. These probabilities were provided in terms of ranges; the geometric mean of these ranges were used in the development and presentation of the results in the FSAR for source terms, radiological consequences and risks. Subsequent to the issuance of the FSAR, DOE received a revised set of probabilities from NASA. These probabilities were presented in terms of distributions for each initiating accident and characterized by a mean and cumulative percentile values. NASA recommended that DOE use the updated probabilities to update the Ulysses FSAR results. Accordingly, at the request of DOE, this letter report has been prepared to evaluate the changes in the Ulysses FSAR results when the updated mean probabilities are used.
