The publication of the Resolution No. 14 dated March 31, 2026, by the Brazilian National Nuclear Safety Authority (ANSN) establishes new requirements for the registration of facilities and the management of naturally occurring radioactive materials (NORM) in the oil and gas exploration and production (E&P) sector, including decommissioning activities.<\/p>\n

The regulation took effect on April 1, 2026, and revoked the CNEN Resolution No. 288\/2021, replacing a more restrictive framework for a model applicable to the entire operational lifecycle. For companies engaged in decommissioning, this means that NORM management must be considered from the technical planning through to the final disposal of materials.<\/p>\n

Daniela Davila<\/strong>, Fernanda Aquino<\/strong>, and Maria Eduarda Cavalcanti<\/strong>, partner and associates in the Energy & Natural Resources area, have prepared a material that consolidates key information on the topic and outlines the changes affecting those engaged in decommissioning.
