Overview of U.S. Nuclear Regulatory Commission Security Activities

摘要

The U.S. Nuclear Regulatory Commission (NRC) regulates both the safety and security of special nuclear material and by-product materials. As such, it has a well developed and robust safety and security regulatory framework. Following the events of September 11, 2001, security was enhanced in a graded risk-informed manner for NRC licensees. Significant activities include issuing an order that required licensees to enhance security, updating design basis threats for radiological sabotage and theft/diversion, updating security regulations for nuclear power plants and developing security regulations for by-product materials. Today, NRC-regu-lated nuclear facilities are among the most secure in the nation's critical infrastructure.
