N.R.C. Nomination Shines Spotlight on Waste-Disposal Issue

WASHINGTON -- When the Senate Environment and Public Works Committee meets on Wednesday to consider President Obama's choice to head the Nuclear Regulatory Commission, three themes are likely to dominate the questioning: waste, waste and earthquakes.
Collegiality and diplomacy may also be mentioned, given that the commission's current chairman, Gregory B. Jaczko, has drawn criticism for his aggressive management style. The nuclear industry would, no doubt, prefer more uplifting confirmation hearing topics, like new reactor construction or progress on radical new designs that would make nuclear plants more useful or economical.
But for the first time, the president has chosen a geologist for the post, Allison M. Macfarlane of George Mason University, and her expertise aligns with the pressing concerns facing Congress and the nuclear industry. She is a longtime critic of the idea of burying waste at Yucca Mountain, a volcanic structure about 100 miles from Las Vegas chosen by Congress in the late 1980s, considering its geology too unpredictable. With little new plant construction, the commission's main responsibility these days is assuring the safety of the 104 plants now operating, and what to do with the decades-old problem of waste.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
