Last week, President Barack Obama announced that he would nominate Dr. Allison Macfarlane, a nuclear waste expert from George Mason University, as the United States’ top nuclear regulator.

Conventional wisdom is that Dr. Macfarlane satisfies all the major political interests involved with the NRC decision. She is a vocal opponent of Yucca Mountain. Harry Reid, check. She is on board with many of the post-Fukushima safety reforms. EPW Chair Barbara Boxer, check. And she is pro-nuclear, Senate Republicans, check.
