RE-EVALUATION OF SHIELD REQUIREMENTS FOR OMR-PIQUA NEUTRON DETECTORS
Technical Report
·
OSTI ID:4233060
Due to major design changes made in the OMR-Piqua radial shield configuration a re-evaluation of shield requirements for the neutron detectors was made. A cylindrical lead-water shield is recommended. The relative thermal neutron flux at the detectors as a function of terphenyl density is shown. The heat generation rates in the lead shielding positioned in front and behind the detectors at full power operation are shown. The radiation level at the source range detector, as a function of time after shutdown following infinite operational periods, is given. (W.L.H.)
