REACTIVITY COEFFICIENTS IN PMA-47 A ZIRCONIUM-URANIUM, UNPOISONED SLAB CORE. PART I. MEASUREMENTS
Technical Report
·
OSTI ID:4824134
The results of measuring neutron flux distributions, distributed reactivity coefficients of U/sup 238/, polyethylene, and zircaloy as well as the spatiatly dependent reactivity coefficients of zircaloy, aluminum, and ztrconium - boron in PMA-47 are reported. PMA-47 is the second of a series of cores constructed in the Plastic Mockup Assembly (PMA) to provide reactivity coefficients and criticality data in cores with simple geometry. It differs from the first core of the series (PMA-40) in that it contains a higher fuel density and utilizes zirconium as its structural material. The reactivity data will be used to test analytical techniques and to provide a comparison with related values for subsequent similar aluminum - uranium cores. (auth)
