The MAJORANA Project: a status report

This series of slides presents the topic under the following aspects: ββ sensitivity, underground laboratory, shield, monoliths, strings, detectors, electroformed small parts, and background. Assembly and construction are proceeding at Sanford Davis Campus laboratory. Based on assays, material backgrounds are projected to meet cleanliness goals. Module 1 is complete. Electroformed copper has just been completed at SURF and PNNL. The shield is nearly complete. Successful reduction and refinement of enr Ge has taken place with 98% yield. AMTEK (ORTEC) has produced 27 kg within 32 detectors from the reduced/refined enr Ge; 30 of these are underground at SURF being assembled into strings.

Status Report on HTR Research, Development, and Deployment in the USA

Abstract – The Gas-Cooled Reactor deployment effort in the United States is a collaboration between the US government and private vendors. The US Department of Energy sponsors the qualification of fuels, materials, and analysis methods that exploit the capabilities of the national laboratories (mainly Idaho, Oak Ridge, and Argonne) to generate the fundamental fuel, material, and core behavior data needed to support design and licensing efforts by vendors in general. Private HTR vendors provide input to the R&D program and engage in the design of the systems, structures, and components that are unique to their design concepts. Their plant design all exploit the properties and behavior of the TRISO fuel, graphite, and alloys being tested in the DOE qualification programs. This paper will summarize the goals and recent progress of the US Gas-Cooled Reactor Program.
