Problem 2: Nuclear Plant Load Factor The reference mode of the load factor of a Nuclear Power Plant is presented in Figure 2. Nuclear Plant Load Factor 100 80 60 Average Load Factor, % 40 20 1978 1980 1982 1984 1986 1988 1990 1992 Figure 2: Nuclear Power Plant Load Factor (Sterman, 2001) 1. Identify the variables that might be responsible for the behavior shown (2 points) 2. Sketch a causal loop diagram to capture the behavior (2.5 points) 3. What counterforces might prevent the state of the system from reaching its goal? (0.5 pts)
