MSBR reprocessing paper for ANS winter meeting (for review) #19

Closed andrewryh closed 7 years ago

andrewryh commented 7 years ago

So, I finished it but it looks like very very bad quality paper. Unfortunately, I didn't obtain good results using Serpent2 capabilities. I feel like the smooth equilibrium with constant K-eff and atomic density cannot be obtained at all. The reason, I think, is the bunch of various isotopes (not only, Pa-233, U-233) which accumulates in the core and have to impact on the core physics.

Gavin&Chvala in their paper (MSRE more focused on reprocessing chemistry) have used the script which simulates adaptive control system + adding GdF3 burnable poison for the first ~200 days. So, I think the only way is to simulate (by script) flow control system like that:

if k-eff < 1.003 than U-233_inflow_rate = U-233_inflow_rate+0.001 & Th-232_inflow_rate = Th-232_inflow_rate+0.001

if k-eff > 1.004 than U-233_inflow_rate = U-233_inflow_rate-0.001 & Th-232_inflow_rate = Th+232_inflow_rate+0.001

But right now I want to change focus to quals for couple weeks if you don't mind.

Anyway, any feedback very welcomed, I still trying to do better paper.

Thanks @andrewryh . Go right ahead and start focusing on quals (related email incoming). I will try to review this tomorrow.
