A furnace in the Specialty Fuels Facility … A furnace in the Specialty Fuels Facility (SFF) was being tested in order to return it to operation. As part of the test, the airflow for the ventilation was checked to ensure that if the airflow decreased to a level below what was required per the Integrated Safety Analysis (ISA), then the appropriate furnace systems would automatically shutdown. During the test with hydrogen gas flowing into the furnace and therefore the ventilation system, the shutdown sequence shutdown the hydrogen flow when the flow was at 100%, but it did not shutdown the hydrogen flow when the flow was at 8%. There was no immediate risk or threat to the safety of workers or the public as a result of this event.</br>An evaluation is currently being performed.</br>BWXT is making this 24 hour report in accordance with 10 CFR 70.61, Appendix A (b)(1) - 'Any event or condition that results in the facility being in a state that was not analyzed, was improperly analyzed, or is different from that analyzed in the Integrated Safety Analysis, and which results in failure to meet the performance requirements of 70.61.'</br>The furnace is shutdown pending further investigation.</br>The licensee will notify the NRC Resident Inspector.</br>* * * UPDATE FROM CHERYL GOFF TO JOE O'HARA AT 1505 ON 01/14/09 * * * </br>On January 9, 2009 BWXT made event notification #44761 regarding a furnace in the Specialty Fuels Facility (SFF) which failed to perform the shutdown sequence for a given hydrogen flow level required per the Integrated Safety Analysis (ISA).
