| Title | Stack Radiation Monitoring System Sampling Capabilities |
| Description | An unresolved item (URI) was identified because additional information and a review of system sampling capabilities is required to determine if there are any impacts to Oyster Creeks emergency plan and to determine if any performance deficiency exists. The inspectors plan to review the additional information after it is complied by Exelon, which had not occurred by the end of this inspection period. As a result of the difficulties experienced with the in-line auto filter change apparatus, Exelon has initiated action to replace the system with an updated model. In the interim, the installed conventional direct in-line particulate and iodine sampling system was placed in service to implement the sampling provisions of Oyster Creeks Offsite Dose Calculation Manual (ODCM). The sampling system continues to autoadjust flow rates to ensure proper collection of isokinetic samples. A separate sampling apparatus provides for sampling of tritium. A review of the availability of the system indicates the system has met requirements for sampling in accordance with the ODCM and has maintained high reliability. At the time of this inspection, the inspectors had not completed a review of potential emergency response implications associated with collection and analysis of particulate and iodine samples during accident conditions, relative to the changes in sample collection methodology (i.e., inability to use the autofilter change-out capability). Exelon is providing additional information regarding collecting samples using the installed in-line particulate and iodine sampling system. Inspectors will review the additional information against the requirements of the emergency plan to determine if a performance deficiency exists.
