Westinghouse submits AP1000 design revision to NRC
Yesterday, the Nuclear Regulatory Commission announced that it has received an application from Westinghouse to renew and update the design certification (DC) for its AP1000 reactor. This application seeks to formally incorporate the lessons learned from the construction of Vogtle-3 and -4 into the design control document (DCD) of the AP1000.
This long-expected submittal builds on previous plans at both the NRC and Westinghouse for the future of gigawatt-scale light water reactor deployments in the United States.

Thin high intensity alpha-particle sources were prepared for the NASA Surveyor Alpha Scattering Experiment. The alpha-active isotope used for this experiment was 242Cm prepared by neutron irradiation of 241Am in a reactor. After irradiation the curium was separated from americium, fission products, and aluminum by liquid-liquid extraction, redox precipitation, and extraction chromatography techniques. The sources were prepared by vacuum sublimation of the curium onto stainless-steel plates, followed by carbon coating from a carbon arc and encapsulation for installation into the Alpha Scattering Instrument.
