This book was released on 1961 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calculations have been made relating to flux-trap reactors constructed in the ZPR-VII critical assembly having heavy water-moderated cores of THUD or Babcock and Wilcox fuel. The flux-trap regions consisted of heavy water, except for a few light water flux traps with THUD-fueled cores. Various flux ratios and quantities, such as ratios of maximum thermal flux to maximum power density or total core power, are compared for THUD-fueled lattices.
