| Title | Failure to Properly Pre-plan a Maintenance Activity |
| Description | The inspectors reviewed a self-revealing noncited violation of Technical Specification 5.8.1 for failure to properly pre-plan the replacement of reactor coolant pump motor A. This failure resulted in the collective dose of a work activity exceeding a five person-rem and the legitimate dose estimate by more than 50percent. Refuel 24 Outage Job Package 08-AP-14, RCP Maintenance, had a dose estimate of 3.551 person-rem but accumulated a final dose of 12.135 person-rem, exceeding the initial dose estimate by approximately 340 percent. The finding was entered into the corrective action program as Condition Report 2008-3321. The licensee is evaluating the condition to determine appropriate corrective actions. This finding is greater than minor because it is associated with the occupational radiation safety program attribute of exposure control and affected the cornerstone objective, in that it caused increased collective radiation dose. The inspectors determined this finding had very low safety significance. The finding involved ALARA planning and work controls, and although the licensees latest official three-year rolling average collective dose was more than a 135 person-rem, the finding involved less than five occurrences. Additionally, this finding had a crosscutting aspect in the human performance area, associated with the work control component, because work planning of maintenance did not consider job site conditions.
