The purpose of this U.S. Nuclear Regulatory Commission (NRC) information notice (IN) is "to alert addressees [all fuel cycle licensees and certificate holders] about recent hydrogen fluoride (HF) exposures. It is expected that recipients will review the information for applicability to their facilities and consider actions, as appropriate, to avoid similar problems. However, suggestions contained in this IN are not new NRC requirements; therefore, no specific action nor written response is required."
