| Title | Part 21 - Notification of Deviation - Sor Qualification Test Report 9058-102 |
| Event Description | {{#Wiki_filter:The following information was excerpted from a facsimile received by SOR:
Pursuant to the requirements of 10CFR Part 21, this letter notifies the NRC of a Part 21 condition. Irradiation testing performed since 1984 did not take into account all of the uncertainties associated with reported doses of gamma radiation to nuclear test specimens for qualification testing. SOR contracted services with lsomedix in 1992 for the radiation aging that was performed per SOR nuclear qualification report 9058-102 Revision 1. Although SOR imposed Part 21 reporting requirements, lsomedix did not include SOR as part of their Part 21 notification. The Part 21 was brought to SOR's attention through an inquiry by a nuclear power station. SOR requested a conference with Steris lsomedix which occurred on November 3, 2016. The teleconference confirmed that the subject radiation aging test results report would be affected by the Steris lsomedix Part 21. As a result, corrections are underway per qualification test report 9058-102 regarding the uncertainty calculations. SOR does not have the capability to perform further evaluations to determine if a safety hazard exists as the specific customer application is unknown. The end user must confirm for each application that the qualified life dose + accident dose + 10% of accident dose is less than or equal to the corrected values. SOR is currently identifying all customers potentially affected by this deviation. At the conclusion of this activity, SOR will notify the customers and the U.S. Nuclear Regulatory Commission in accordance with the requirements of 10 CFR Part 21.
The following is an excerpt of an updated Part 21 received via email: Corrections are now complete to test report 9058-102 regarding the uncertainty calculations. The calculations changed from 8% uncertainty to 9.6% uncertainty for the minimum irradiation aging. SOR does not have the capability to perform further evaluations to determine if a safety hazard exists as the specific customer application is unknown. The end user must confirm for each application that the qualified life dose + accident dose + 10% of accident dose is less than or equal to the above noted values.
