PART 21 NOTIFICATION - POWER SUPPLY UNIT IS LIMITED AT ELEVATED TEMPERATURES
"In accordance with 10CFR Part 21, Nutherm International, Inc. has opened an evaluation for a potential reportable condition.
"Based on testing results of a production unit of a Nutherm Power Supply, part number 55320, the unit may not perform at elevated temperatures (at or above 120 °F) at its rated nameplate output rating of 20 Amps indefinitely. Preliminary reviews indicate that at ambient air temperatures of 120 °F or greater, the rectifier employed in the design may be limited to output currents of 15 Amps or less.
"There have been no reports from customers concerning failures of these units as a direct result of this issue. If a reportable condition exists TVA (Browns Ferry) and Exelon (Quad Cities, Dresden, Peach Bottom) will be contacted."
* * * RETRACTED ON 04/09/2008 AT 1835 EDT BY LEONARD HINSON TO FANGIE JONES * * *
The reporting organization provided the following information via facsimile:
"Nutherm has completed its investigation and concluded that all units supplied to customers meet the requirements of the Nutherm environmental qualification reports. Review of the qualification reports for these units indicates that the units were to operate at a maximum of 15.1 Amperes at temperatures up to 120°F. Some of the qualification reports also require that the units operate up to 15.1 Amperes at 160°F for 15 minutes. The results of our investigation indicate that the units supplied will meet the operating and accident requirements as stated in the qualification reports.
"Based on the results of this investigation, Nutherm International, Inc. has concluded that a reportable condition does not exist."

POTENTIAL PART 21 NOTIFICATION REGARDING TORUS IMMERSION/VAPOR PHASE COATINGS
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."
Duane Arnold Energy Center - DAEC has been contacted.
Facilities with CZ-11 substrate and repairs performed with Picco UT-15, but may be exempt from Part 21 impacts are as noted:
Cooper Nuclear Station- NPPD has been advised of the finding as a courtesy.
Pilgrim Nuclear Station - PNS has been advised of the finding as a courtesy.
Peach Bottom - PBAPS has been advised of the finding as a courtesy. |
