This unplanned condition is reportable as a loss of assessment capability per 10 CFR 50.72(b)(3)(xiii).</br>Comanche Peak Nuclear Power Plant (CPNPP) has assurance of steam generator integrity and fuel cladding integrity and there is a negligible safety significance to the current condition from a public health and safety perspective.</br>Additionally, compensatory measures are in place to assure adequate monitoring capability is available to implement the CPNPP emergency plan in the unlikely event of challenges to the steam generator or fuel cladding. The N16 (Nitrogen-16) radiation monitor serves as a backup with alarm function and Radiation Protection technicians have been briefed on taking local readings with a Geiger-Mueller tube on MSL (Main Steam Line) 2-02.</br>Corrective actions are being pursued to restore 2-RE-2326 to functional status.</br>The NRC Resident Inspector has been notified.
