4 In April 2000 NRC implemented the new Reactor Oversight Process The new process revised, and for the first time, integrated NRC’s inspection, assessment and enforcement programs The new process revised, and for the first time, integrated NRC’s inspection, assessment and enforcement programs This presentation will describe This presentation will describe ã Reasons for the change ã Results to date

Despite objective evidence of improving safety, NRC Violations continued to increase
Increase was driven by a 100% jump in Level IV Violations (minor process and procedure errors)
The consequences of the old approach were significant, both economically… …AND in diverting NRC and industry resources from focusing on more risk significant areas
17 NRC agreed a new approach was appropriate NRC’s internal reviews found the previous approach inefficient, untimely, very subjective and inscrutable to licensees and the public NRC’s internal reviews found the previous approach inefficient, untimely, very subjective and inscrutable to licensees and the public Advances in risk assessment provided confidence that risk-informed performance indicators and simplified risk analyses could be used as effective assessment tools Advances in risk assessment provided confidence that risk-informed performance indicators and simplified risk analyses could be used as effective assessment tools
