Laboratory Testing of Nuclear-Grade Activated Charcoal (ERRATA); Issue

The Nuclear Regulatory Commission (NRC) has issued the errata for a typographical error that was found in Generic Letter (GL) 99-02. GL 99-02 addresses the laboratory testing of nuclear-grade activated charcoal that is used in the safety-related air-cleaning units of engineered safety feature ventilation systems of nuclear power plants to reduce the potential onsite and offsite consequences of a radiological accident by adsorbing iodine. The typographical error makes the sentence in which it appears technically incorrect. This sentence appears in two places, namely, in Requested Actions 2 and 3, on page 7 of the generic letter. The affected sentence reads ``If the system has a face velocity greater than 10 percent of 0.203 m/s (40 ft/min), then the revised TS [technical specification] should specify the face velocity.'' This sentence should read ``If the system has a face velocity greater than 110 percent of 0.203 m/s (40 ft/min), then the revised TS should specify the face velocity.''
