How will the new guidance on analytical methods and uncertainty analysis for online monitoring systems be used by the staff?
The safety evaluation report (SER) that approved the generic concept of online monitoring (OLM) also mandated 14 requirements that an OLM system would have to meet if the calibration frequency were to be extended (including the need to conduct a detailed uncertainty analysis). Additionally, the SER did not provide any guidance on the acceptability of any particular analytical method for implementing OLM for calibration frequency extension. The new guidance will provide the staff with detailed technical information that it can use to evaluate licensee responses to the 14 requirements in the SER and with methods for identifying and evaluating the assumptions and limitations associated with the analytical methods that are being applied in OLM systems.
