Question
Env. 3.33 To control the risk of severe core damage during a commercial nuclear power station blackout accident, the reliability of the emergency diesel generators to start on demand must be maintained at a high level. The paper "Empirical Bayes estimation of the reliability of nuclear- power emergency diesel generators" Technometrics (1996) 38:11-23] contains data on the failure history of seven nuclear power plants. The following data are the number of successful demands between failures for the diesel generators at one of these plants from 1982 to 1988. 28 50193 55 4 7 147 76 100 10 84 0.9 10(62 26 15 226 54 46 128 4 105 40 4 273 164 7 55 41 126 6 (Note: The failure of the diesel generator does not necessarily result in damage to the nuclear core because all nuclear power plants have several emergency diesel generators.)Explanation / Answer
