| Title | Part-21 Report - Nutherm Irradiation Certification with Insufficient Margin |
| Event Description | {{#Wiki_filter:The following report was received via fax:
SOR Inc. was notified by Nutherm International, Inc. that irradiation certification performed by Steris Isomedix did not meet the additional 10 percent margin to meet the requirements of IEEE 323 due to measuring and test equipment uncertainties. This issue was originally identified by STERIS lsomedix Services, Whippany, New Jersey as part of NRC Inspection Report No. 99901445/2014-201. Nutherm International, Inc. has completed their evaluation of work performed for SOR, Inc. and has identified a potential impact to the conclusions of equipment qualification testing under SOR Inc. purchase order number 166984. Nutherm International, Inc. has reported this potential issue and forwarded an update to the NRC per Event Notification Report Number 50359. SOR Inc. is conducting an evaluation of projects to determine whether a defect or failure to comply exists as defined by 10 CFR Part 21. At the conclusion of the evaluation, any customer impacted by this issue will be notified and the U.S Nuclear Regulatory Commission will be notified in accordance with 10 CFR Part 21.21. If you have any questions regarding this issue, please contact Mike Bequette, Vice President of-Engineering at (913) 888�2630 or email mbequette@sorinc.com.
The following updated information was excerpted from a SOR, Inc. report received via email: As a result, corrections were made to test report SOR-12043R revision 1, approved 9/8/2015. The uncertainty calculations by the radiation lab used for the qualification program reduced the qualification level from 35 Mrad to 33.8 Mrad. SOR found that there were three switches potentially affected as shown [on table I provided with this report]. While these switches were shipped before completion of the of test report SOR-12043R, revision 0, it has been established that there was a contractual agreement between SOR and Xcel Energy-Monticello Nuclear Generating Plant that these switches would be equivalent to those to be qualified in the new test report. Also listed are recipients of the original test report SOR-12043R revision 0 [on table II provided with this report]. In either Case, SOR does not have the capability to perform further evaluations to determine if a safety hazard exists as the specific customer application and end use is not known by SOR. Since the release of revision 0 of the test report, SOR has not provided certificate of conformance to any 141 series product shipped citing the 12043R test report other than qualification units for Excel Energy - Monticello Nuclear Generating Plant. Recipients, Customer, Utility Names: - Xcel Energy - Monticello Nuclear - Progress Energy - Brunswick - Entergy Corporation - Pilgrim In accordance with the requirements of 10 CFR Part 21.21, the customers listed have been notified regarding this issue to allow them to evaluate this deviation or failure to comply and its potential safety hazard. lf you have any questions regarding this matter, please contact; For technical issues; Joe Modig SOR Inc. 14685 W. 105th Street Lenexa, KS 66215-2003 Ph: (913) 956-3046 jmodig@sorjnc.com And for any other questions; Melanie Dirks Director of Quality Assurance SOR Inc. 14685 W. 105th Street Lenexa, KS 66215-2003 Ph: (913) 956-3160 Email: mdirks@sorinc.com Notified R1DO ( Welling), R2DO (Sykes), R3DO (Dickson), R4DO (Pick), and Part 21 Reactors and Part 21 Materials via email. }}[[Event description::Description::{{#Regex_clear:The following report was received via fax: SOR Inc. was notified by Nutherm International, Inc. that irradiation certification performed by Steris Isomedix did not meet the additional 10 percent margin to meet the requirements of IEEE 323 due to measuring and test equipment uncertainties.
