ASME ANS RA-S-1.1

Standard for Level 1/Large Early Release Frequency Probabilistic Risk Assessment for Nuclear Power Plant Applications

ASME ANS RA-S-1.1 is a standard jointly issued by the American Society of Mechanical Engineers (ASME) and the American National Standards Institute (ANS), serving as a guide for reliability analysis in nuclear facilities. This standard primarily guides the process of reliability analysis in nuclear facilities such as nuclear power plants.

RA-S-1.1 covers various aspects including data collection, analysis methods, interpretation of results, and reporting requirements. It provides detailed guidance on the fundamental concepts and methods of reliability engineering to ensure the reliability of nuclear facilities during operation and design.

The implementation of this standard aims to assist in assessing the safety and reliability of nuclear facilities to meet regulatory and industry requirements. Through systematic analysis of potential failures, accidents, and incidental events, a better understanding and management of the risks associated with nuclear facilities can be achieved, thereby enhancing their safety and reliability.
