Analytical Results of MOX Colemanite Concrete Sample Poured July 25, 2012 -- Cured 28 Days
The Mixed Oxide Fuel Fabrication Facility (MFFF) will use Colemanite bearing concrete neutron absorber panels credited with attenuating neutron flux in the criticality design analyses and shielding operators from radiation. The Savannah River National Laboratory is tasked with measuring the total density, partial hydrogen density, and partial boron density of the colemanite concrete. Samples 8.1.2, 8.2.2, 8.3.2, and 8.4.2 were received on 8/1/2012 and analyzed after curing for 28 days. The average total density measured by the ASTM method C 642 was 2.09 g/cm 3 , within the lower bound of 1.88 g/cm 3 . The average partial hydrogen density was 7.48E-02 g/cm 3 as measured using method ASTM E 1311 and met the lower bound of 6.04E-02 g/cm 3 . The average measured partial boron density was 1.71E-01 g/cm 3 which met the lower bound of 1.65E-01 g/cm 3 measured by the ASTM C 1301 method.
