ALARA Review for Concrete Sampling and Robot Deployment at221-U
This document is an as low as reasonably achievable (ALARA) review for performing characterization activities at 221-U Plant (U-Plant) in support of the Canyon Disposition Initiative. The scope of work includes sampling concrete and deployment of the robot into the ventilation tunnel to support characterization activities. While performing a radiological review of the work scope, it was determined that contamination levels in the work area may exceed the Level 2 ALARA review trigger levels specified in BHI-SH-02, Volume 1, Safety and Health Procedures, Procedure 1.22, Planning Radiological Work. This ALARA review provides a description of the engineering and administrative controls used to manage personnel exposure, control contamination levels, and control airborne radioactivity concentrations while conducting characterization and sampling activities at the 221-U Plant (U-Plant).
