The reporting organization provided the following information via facsimile:
NUPIC identified that a potential problem of unqualified coatings exists with results of the 1996 DBA/Irradiation Test on February 29, 2008. UESI initiated Nonconformance Report NCR # 2008-01, insured that no coating applications were scheduled in Nuclear facilities requiring adherence to ANSI N101.2-1972, notified parent company President of potential Part 21 and under his directive began investigation.
Based on NUPIC Audit No. 08.03SPAFL.08. 1, Finding No. 1, a review of Historical Design Basis Accident (DBA) / Irradiation Test Results dated 12/16/1996, and subsequent internal investigation and evaluation, it has been determined that UESI Proprietary Underwater Coating Picco UT-15, when applied over the substrate Carboline CZ-11 only, does not meet all acceptance criteria of ANSI N101.2-1972 and ANSI N5.12-1974 for DBA qualified Coating Service Level I repair material.
The evaluation concluded, that while Picco UT-15 is fully qualified to ASTM D-3911-95 for all Service Level I and Torus/Immersion Area coating repairs on all substrates tested, use of the product should have been limited to ANSI N101.2-1972 qualified on all substrates tested with the exception of CZ-11.
Beginning immediately, UESI will cease to market and install its product as ANSI N101 .2-1972 / N5.12-1974 irradiation and DBA qualified when applied as a repair material over Carboline CZ-11 substrate.
Identification of the facility the activity or the basic component supplied for such facility or such activity within the United States which fails to comply or contains the defect.
