Computational Support for the UMLRR
Prof. John R. White

This page identifies a sequence of papers, reports, and student theses that document much of the work that has been performed over the years in support of the UMass-Lowell research reactor (UMLRR). A brief historical overview puts our work into perspective and it provides some justification for the particular categorization given below. Full versions of many of the more recent materials are available in either html or pdf format for your review, as desired. Hopefully some of these will be useful in your work/studies. Enjoy!!!
