Radiological Design Review Screening Steel Cover Plate Replacement at 241-U-107
- CHG
This document provides the calculated basis for the level of radiological design review required for the replacement of the existing 241-U-107 pump pit 5.1 cm (2 inch) steel cover plate with a 7.6 cm (3 inch) carbon steel plate. The determination of the expected dose rate over the 241-U-107 pump pit after the installation of a 5.1 cm (2 in.) or alternatively 7.6 cm (3 inch) cover plate is described. The existing 61 cm (24 inch) concrete cover block must be removed to provide access for saltwell pumping. The pit opening will be covered by a 5.1 cm (2 in.) or 7.6 cm (3 inch) carbon steel plate. Also calculated is the lifecycle dose due to this facility modification including replacement of the concrete cover block with a steel plate, and operation of the Hose-in-Hose Transfer Line (HIHTL).
