The following information was received by facsimile:
This serves as notification to the U.S. Nuclear Regulatory Commission (NRC) of a possible deviation or defect in nuclear qualified High Efficiency Particulate Air (HEPA) Filters manufactured by Flanders Filters.
Flanders Nuclear HEPA Model T-007-W-43-05-NU-51-23-GG-FU5 failed requalification testing at Edgewood Chemical Biological Center (ECBC). This failure was related to the 'Resistance to Pressure' test required per ASME AG-1, Section FC5140.
On November 19, 2013, Flanders received a report from ECBC indicating failure of this filter model to re-qualify per the requirements of ASME AG-1, Section FC. Flanders is investigating the failure, but at this time do not believe Flanders has the ability to determine if this could create a substantial safety hazard because we do not have specific knowledge regarding the actual application the filters are being used in at each site.
Customers supplied this model Filter, or filters with the same media type and pack style, since the last qualification of the media type and pack style on July 18, 2012 are being notified.
In accordance with 10CFR Part 21.21(d)(4), Flanders will provide written notification to the NRC within 30 Days with additional information including corrective actions where applicable.
The customers include the following: SCANA; Nuclear Fuel Service; Premier Technology Incorporated of Blackfoot,
Idaho; and Energy Northwest.
