Practical Methods to Identify, Prepare and Manage Abnormal Events
Tuesday, April 12, 2016 - 10:45am to 11:15am
Through extensive research, technical studies, and discussions, the industry and the regulatory body came to consensus on an approach. The use of realistic, best-estimate calculations, unlike the conservative, specific design-basis calculations typically performed in the past, resulted in a reasonable picture of consequences and expected actions. A measure of relative risk and risk improvement for such changes can also be quantified and compared.
The defense-in-depth concept was used. This minimized the impact to existing plant configuration. Flexibility was also desired to avoid limiting the assessments to specific scenarios. It was desired to have the solutions be as independent from the initiating event as possible to maximize its usefulness.
This paper will examine and discuss the challenges faced by the U.S. nuclear industry after 9/11 and the Fukushima accident, the process to determine the appropriate path to success, and the solutions themselves. It will show that the solutions were effective, useful, and cost-effective.
It will also compare the nuclear industry methods and regulations for risk and security management with fuel and petrochemical industry standards and guidance such as API’s Security Guidelines for the Petroleum Industry, Security Risk Assessment Methodology for the Petroleum and Petrochemical Industries, and Security Vulnerability Assessment Methodology for the Petroleum and Petrochemical Industries.
It is possible the fuel and petrochemical industry may glean valuable lessons from the experience of the nuclear industry regarding security and risk mitigation.
