[en] Subsequent to shutdown of the Peach Bottom High-Temperature Gas-Cooled Reactor for decommissioning, steam generator and primary circuit ducting samples were removed for subsequent evaluation and design methods verification. Component removal site work commenced with establishment of restricted access areas and installation of controlled atmosphere tents to retain relative humidity at less than 30 percent. A mock-up room was established to test and develop the tooling and train operators under simulated working conditions. Primary circuit ducting samples were removed by trepanning, and steam generator access was achieved by a combination of arc gouging and grinding. Steam generator tubing and other samples were removed by internal cutting and side grinding. The special tooling used was developed by Power Cutting, Inc., under subcontract to Catalytic, Inc. Throughout the component removal phase, strict health physics, safety, and quality assurance programs were implemented
