Title | Plastic Shipping Plug in Rosemount Transmitter |
Description | The inspectors identified a finding for the licensees failure to properly install a flow transmitter for the containment spray system. Specifically, since construction, Rosemount Transmitter ENFT0005, which provides a signal for containment spray train A pump flow rate, had a plastic shipping plug installed in the spare conduit port instead of the vendorrequired stainless steel plug. The licensee did not include this transmitter as part of an operating experience extent of condition walkdown conducted in 2010 because the transmitter provides indication only and does not have an active safety function. However, the inspector determined that this transmitter provides operator post-accident monitoring capability of containment spray pump performance. The licensee entered this issue into the corrective action program as Callaway Action Request 201403300. The licensee reviewed this deficiency and determined that although Transmitter ENFT0005 was degraded, the containment spray system remained operable. The licensee promptly replaced the plastic shipping plug with the required stainless steel plug. Failure to properly install a Rosemount transmitter needed for post-accident monitoring to its qualified configuration was a performance deficiency. This performance deficiency was more than minor, and therefore a finding, because it adversely affected the configuratio
control attribute and the Barrier Integrity Cornerstone objective to provide reasonabl assurance that physical design barriers (i.e., containment) protect the public fro radionuclide releases caused by accidents or events. Specifically, the improperly configured containment spray flow transmitter could have resulted in erratic spray flow indication, which could impede operators ability to monitor this parameter and act upon the indication. The finding is of very low safety significance (Green) because containment spray is not a significant contributor to large early release frequency. This finding does not have a cross-cutting aspect because the transmitter was installed in this manner during original construction and, thus, was not indicative of current licensee performance. |
