All U.S. nuclear power plant (NPP) sites have had some groundwater contamination from radioactive leaks, and some of these leaks came from underground piping systems (UPS). The NRC regulates NPP to protect public health and the environ. from radiation hazards. This report: (1) determines experts' opinions on the impacts, if any, of UPS leaks on public health and the environ.; (2) assesses NRC requirements of licensees for inspecting these systems and monitoring and reporting on leaks; (3) identifies actions the nuclear power industry, licensees, and NRC have taken in response to leaks; and (4) identifies additional NRC requirements that stakeholders think could help prevent, detect, and disclose leaks. Illus. This is a print on demand report.

Unearth the Secrets of Designing and Building High-Quality Buried Piping Systems This brand-new edition of Buried Pipe Design helps you analyze the performance of a wide range of pipes, so you can determine the proper pipe and installation system for the job. Covering almost every type of rigid and flexible pipe, this unique reference identifies and describes factors involved in working with sewer and drain lines, water and gas mains, subway tunnels, culverts, oil and coals slurry lines, and telephone and electrical conduits.
