Due to time limitations, we need to do this via the fastest and easiest path. This will not be beautiful, it will not be precise, but it will provide a nice indication of our expected burnup and radioinventory.
Planned routine:
1: Simulate burnup of a conventional PWR rodlet (40 GWd/mTHM) and store for x time (20-30 years).
2: Extract initial fuel composition and insert into our deck.
3: Simulate burnup in some realistic time step size (1 day or one week). (double for loop)
4: If 1<Keff<1.1 then continue to 5, else add/remove thorium or SNF and iterate back to 3.
5: Extract burned fuel - run chemistry algorithm - write new deck.
6: Iterate back to 3 for the next time step, until the burnup is acceptable.
7: Extract and assemble information from the above burnup routine – plot it!
As fare as I can see the above requires the following sub-routines:
A: Output reader/writer.
B: MCNPX model of PWR.
C: MCNPX model resembling at MSR.
D: Chemistry algorithm. (gas bobbling and in situ reprocessing, plus initial fuel fabrication modification (gas and volatile removal))
E: MCNPX re-run Iterator for the cluster.
