Analytical Results of Mox Colemanite Concrete Sample Poured May 4, 2012

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. The Savannah River National Laboratory is tasked with measuring the total density, partial hydrogen density, and partial boron density of the colemanite concrete. Sample 04 May 12/Test/S1-1, S1-2, and S1-3 was received on 5/9/2012 and analyzed. The total density measure by the ASTM method C 642 was 2.00 g/cm3, within the lower bound of 1.88 g/cm3. The partial hydrogen density of 6.35E-02 g/cm3 as measured using method ASTM E 1311 met the lower bound of 6.04E-02 g/cm3. The measured partial boron density of 1.88E-01 g/cm3 exceeded the lower bound of 1.65E-01 g/cm3 when the sodium peroxide fusion dissolution method was used in place of the prescribed ASTM C 1301 method.
