Kernel dead during depletion analysis

Reference.ipynb (52.3 KB)

I have attached my code here. When I use boron._depletable = ‘true’ this command in my depletion analysis it shows these error messeages

But when i didnt use boron._depletable = ‘true’ this command the same code run fine. How can i sort this out? or, What is the correct way by which i can deplete my boron using this code?
