Average Burnup

Hi,

When burning the core using "dep" is it the average burnup or maximum burnup that I enter?

Thanks,

Jordan

Re: Power Distribution for each burnup step using SIE method

So in order to get the power distributions with a detector at a specific burnup, using the restart capability, what am I not doing incorrectly?

In addition, your comment about 'normalized total reaction rate' do I need to use 'set arr'?

Re: Power Distribution for each burnup step using SIE method

That is very odd. I am doing two simulations: Step 1: Doing a burnup simulation and using 'set rfw' to write the results to a seperate file Step 2: Running it again with 'set rfr' to find the power distribution at specific burnup points with detectors or set cpd. When I do step 1 my reactor has a mu...

Re: Power Distribution for each burnup step using SIE method

Okay sounds good, thank you! When I run my initial burnup simulation and us 'set rfw' I use 'set power' for normalization. However, when I run 'set rfr' and use 'set power' it gives me an error that says: "Error in normalization: zero fission power". Could you provide some direction as to what this ...

Re: Power Distribution for each burnup step using SIE method

At the end of your last comment you posted, "Regardless of the being able to print-out some results during corrector steps, if using SIE-scheme, I would (strongly) suggest to perform the calculation in two-steps - with the original source" When you are talking about the two-steps are you talking abo...

Re: Power Distribution for each burnup step using SIE method

With the modifications you suggest I make to the code, what is the bare minimum input I need to determine the core power distribution in my reactor core at each given burnup step? If burn my core with the latest code changes you suggested for score.c and printcordistr.c , and I use the input line 's...

Re: Power Distribution for each burnup step using SIE method

After making these modifications I need to have lines for 'set pcc' and 'set sie' correct? For 'set pcc' which mode should I be using? I have tried all of them and they seem all very similar to me. Is there would that you would recommend or prefer over another? Do I need to do 'set rfw' and 'set rfr...

Re: Power Distribution for each burnup step using SIE method

Hi Ana, I made the changes in the files you mentioned. However, when I run the 'cpd' card with the line: set cpd 3 100 0.0 170 I don't get all of the different files you mentioned generated. You wrote "'_core[BURNUP].m' (predictor) and '_core[BURNUP]_CI_[ITER].m' (corrector) files are generated." I ...

Re: Power Distribution for each burnup step using SIE method

Hi Ana, My apologies for continuing to ask questions. I would prefer to use 'cpd' if it is possible. I went ahead and made the associated changes in printcoredistr.c as outlined in an earlier comment. I also added #define STAB_BURN as you suggested. However, cpd is still just outputing the power dis...

Re: Power Distribution for each burnup step using SIE method

Hi Ana, Thanks for getting back to me! So just to confirm, I can find the power distribution for a given pin in each pin and assembly in the core using detectors instead of the 'cpd' card? All I need to do is add the code below and everything will work? Or do I need to add the code below to be able ...
