Abstract not provided.

Sandia National Laboratories Radiation Protection department did not successfully address the causes leading to the issue NTS-SS-SNL-NMSITE-2017-0004, “Contamination Monitor Left in Service After Inadequate Calibration”, nor identify through the verification and validation process that corrective actions were not fully implemented and effective at addressing the issue(s). This report is the third causal in four years associated with the iPCM12 instrument and the Radiation Protection Instrumentation (RPI) organization within Radiation Protection (00628).

On June 5th, 2020 Sandia National Laboratories signed and recommended for closure the evidence package for the Noncompliance Tracking System NTS—SS-SNL-NMSITE-2017-0004, Contamination Monitor Left in Service After Inadequate Calibration. On July 16th, 2020 the Sandia Field Office sent a follow-up question list to the Radiation Protection Instrumentation Program Lead to clarify some points while reviewing the evidence package. The follow-up questions readily identified deficiencies with all three calibrations of the iPCM12 systems. On July 30th, 2020 Radiation Protection hosted a meeting to better understand the exact nature of the concerns, determine if the iPCM12 machines were out of calibration and therefore would have to be taken out of service. One result of this meeting was to determine if SNL could withdraw the evidence package. SNL transmitted a letter on August 26th, 2020 recalling the evidence package and committed to performing a thorough causal analysis and invoke the required issues management processes to ensure that corrective actions are sustained.
