I'm currently enrolled in a course in which we will be modeling parts of a nuclear reactor utilizing Westinghouse ANC code. Here are my questions: My professor said we will be doing coding on Unix-based machines; so, does that mean the ANC code is FORTRAN 90 based? Secondly, when performing calculations in ANC using neutron transport theory, does the process involve a lot of computational overhead? Could I install a Unix distro on my PC and (on the off chance we are allowed to have private copies of ANC) work on a project, or just tinker around with it, on my own time and computer? Lastly, if one does not reduce the number of equations coming from transport theory (via simplifications and assumptions), are the calculations primarily parallel; seeing as the same equations are being used, just with inputs and dimensions as the variances? I'm wondering if using a multi-core PC makes enough of a beneficial difference in chugging through the calculations to justify having my primary computer inaccessible for some time. Additionally- it is terribly difficult finding any information out about ANC. From what I deduced from some face-time with google, ANC9 is FORTRAN 90 based, where as ANC-H (as far as I know we are not going to use the hexagonal ANC) is written and worked with in either FORTRAN 77 or FORTRAN 95.
