Committee to Bridge the Gap filed a Petition for Rulemaking (PRM-73-12) to NRC, as posted to this page, in request of requiring nuclear power stations to significantly upgrade their Design Basis Threat (DBT) to include raising physical obstructions around reactors and their critical structures to shield the sites from aircraft attack. The petition also seeks to raise nuclear site security response capabilities to repel at minimum 19 attackers or the equivalent force used on against U.S. targets. Over 700 comments, largely in support of the petition for rulemaking were received by NRC and will be posted to http://ruleforum.llnl.gov/cgi-bin/rulemake?source=ctbg_prm&st=petitions-a including comments by NIRS and the combined comments of seven State Attorneys General for Arkansas, Arizona, California, Connecticut, Illinois, New York, and Wisconsin. Additionally, the Attorney General from Delaware filed support comments.
