Title: 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 enrGe has taken place with 98% yield. AMTEK (ORTEC) has produced 27 kg within 32 detectors from the reduced/refined enrGe; 30 of these are underground at SURF being assembled into strings.
