Making her first appearance before Congress as chairman of the Nuclear Regulatory Commission, Allison Macfarlane called July 24 for more post-Fukushima safety reforms and remained neutral on the stalled Yucca Mountain nuclear waste project in Nevada. Kristine Svinicki, William Magwood, and William Ostendorff also testified before the House Energy and Commerce Subcommittee on Energy and Power and the Subcommittee on Environment and the Economy. Committee Republicans focused heavily on the commission chairman’s statutory authority and whether it should be curbed.
