LATTICE MEASUREMENTS WITH 7-ELEMENT UO$sub 2$ CLUSTERS IN ZED-2. PART I: BUCKLINGS OVER A RANGE OF SPACINGS WITH THREE COOLANTS
Technical Report
·
OSTI ID:4811448
Buckling measurements were made in ZED-2 in a series of hexagonal lattices of 55 7-element UO/sub 2/ clusters with spacings from 18 cm to 36 cm. Three materials in the cluster coolant region were investigated: D/sub 2/O of moderator purity; helium, to simulate a voided condition; and an organic liquid, HB-40. The experimental results were compared with values calculated using the latest Chalk River lattice recipes. Buckling measurements made previously with these 7-element UO/sub 2/ clusters in ZEEP are in agreement with the measurements made in ZED-2. A short description of the ZED-2 reactor is included.
