A new ANSI/ANS standard for liquid metal fire protection published

September 8, 2025, 1:03PMANS News

ANSI/ANS-54.8-2025, Liquid Metal Fire Protection in LMR Plants, received approval from the American National Standards Institute on September 2 and is now available for purchase.

The 2025 edition is a reinvigoration of the withdrawn ANS-54.8-1988 of the same title. The Advanced Reactor Codes and Standards Collaborative (ARCSC) identified the need for a current version of the standard via an industry survey.

Typical liquid metal reactor designs use liquid sodium as the coolant for both the primary and intermediate heat-transport systems. In addition, liquid sodium and NaK (a mixture of sodium and potassium that is liquid at room temperature) are often used in auxiliary heat-removal systems. Since these liquid metals can react readily with oxygen, water, and other compounds, special precautions must be taken in the design, construction, testing, and maintenance of the sodium/NaK systems to ensure that the potential for leakage is very small.

Building momentum for a stronger ANS

The 2025 ANS Annual Conference in Chicago was a powerful springboard to begin my term as president. With over 1,400 attendees, it was one of our most dynamic gatherings in recent memory—full of energy, ideas, and a shared commitment to advancing nuclear science and technology.

As we move forward, my focus is clear: to elevate the role of nuclear in environmental protection, national security, energy diversity, and grid stability. These priorities are not just strategic—they are essential to a cleaner, more resilient future.

The goals I laid out at the conclusion of the Board of Directors meeting in June are simple, but I am sure they will be effective in engaging our community.

One simple change to start is the move away from the term meetings—the American Nuclear Society now uses the term conferences to describe its two yearly flagship gatherings, to more appropriately reflect the more than 1,000 attendees that these events bring together.
