Simpy v.1 State 1 Results ( Directly following the decay of U-235)


Here we can see the results graphed. The simulated code doesn't provide us with a stateTime at this point, so it assumed that this is the equivalent of State 1, stateTime 0.

It is encouraging here to see the double peaks; that is usually a good visual indication that the simulation is generating the results that we should expect. For comparison, below we show the graph that we are using for our benchmarks (http://en.wikipedia.org/wiki/Fission_product_yield).

Comparing the two graphs highlights some issues with our Simulation.

  1. The States doesn't match up well. The Benchmark graph shows results for 1, 10, 100, and 1000 years. Ours output shows only the results directly following fission. 
  2. The values are not "spiking" on the elements where it would be expected. Indeed, the benchmark doesn't show a value for Pm (Prometheum), yet our results show a high frequency of Pm resulting from the decay of U-235
  3. Our values are measured in absolute values, where their values are measured as a fission yield percentage. Without the prior tow issues so prominent, we would correct this issue and compare the results a second time.
  4. Semantic issue, but the labels on our x-axis don't match theirs. This isn't a critical break in the process, but could certainly lead to some confusion in interpreting the results.
