A new ANSI/ANS standard for liquid metal fire protection published
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The 2025 edition is a reinvigoration of the withdrawn ANS-54.8-1988 of the same title.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.

Precision injection casting is a method developed at Argonne National Laboratory to produce semifinished fuel pins. It has been adapted to the remote refabrication of EBR-II fuel. Inert gas pressure is used to force molten fuel alloy into thoria-coated, precision-bore, high silica glass molds. During EBR-II, Core I production, 16,000 fuel castings were produced in batches of 120 using an experimental injection casting furnace. The specified weight, diametral tolerance, surface finish and internal soundness specifications were successfully met. Remote controlled equipment was designed from experience gained during Core I production.
