Specify in Abstract below or in CONCLUSION A root cause analysis determined that the reason for not complying with the TS was the inappropriate use of turnover logs as the sole method to track long term off-normal plant status information. This resulted in insufficient system status information barriers (labels, tags, etc.) being present to remind operators of the off-normal alignment of the Waste Gas System.
CORRECTIVE ACTIONS
A sample was obtained and it verified that the gas in the tank did comply with TS 2.9(1) as required.
Criteria have been developed for weekly review of turnover sheets to ensure sufficient status control barriers for components (labels, tags, etc.) are in place. A weekly preventive maintenance task has been created for the Shift Manager to review turnover logs and ensure status control barriers (labels, tags, etc.) are in place using the developed criteria.
SAFETY SIGNIFICANCE
The gas monitor provides an early warning to the operators if a flammable mixture of gas is being transferred to the waste gas tank. While it is possible for the gas mixture in the vent header to contain a flammable mixture, in this instance, the gas mixture in WD-29B was well within the flammable limits for the gasses. A flammable mixture did not exist, therefore there was no impact to the health and safety of the public due to this incident.
SAFETY SYSTEM FUNCTIONAL FAILURE This event does not result in a safety system functional failure in accordance with NEI-99-02.
