PWR or BWR cross sections for burnup simulation of a pool-type reactor 1

sleepingSatellite · Mar 28, 2018

I have to do a burnup simulation of fuel in a pool-type research reactor.
But I only have cross section sets for BWR and PWR.
In your opinion which one of the two available cross section sets fit the best for the pool-type reactor and why ?

Thanks.

Neither. You must use the actual situation of your core.

A 1200 Megawatt core in a high pressure water reactor (either saturated or pressurized) is going to burn up differently because of the fuel locations and core size very, very differently than the open-pool low-watt research reactor. Your flux shape is different, core poisons are different at the start of the fuel load cycle, and control rods reactions are different.
