A fully-enriched U-235 reаctоr is оperаted fоr severаl weeks at a thermal flux of 1.75×1013 n/(cm2·s) and fuel temperature of 600°C.  The reactor is then tripped and drops to a temperature of 200°C.  Determine the Xenon reactivity worth (in dollars, $) just before the reactor is scrammed.  You may assume that the thermal-averaged macroscopic fission cross-section (Σf-bar) is 0.0140/cm.
