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The 2025 edition is a reinvigoration of the withdrawn ANS-54.8-1988 of the same title.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.

Transuranium elements will be produced by long-term neutron irradiation of Pu-Al alloy to produce Pu242, Am243, and Cm244, which will be irradiated in the High Flux Isotope Reactor to produce berkelium, californium, einsteinium, and fermium. Methods based primarily on ion exchange and solvent extraction are outlined for processing both irradiated Pu-Al alloy and irradiated HFIR targets. The calculated content of irradiated Pu242 and Cf252 HFIR targets is given.
