| Title | Potential Issue Regarding Incorrect Industrial Irradiation Dose |
| Event Description | The following information was received via facsimile:
Nutherm International, Inc. was notified by Steris Isomedix Services that the applied radiation dose reported on their Component Irradiation Certificates did not account for all uncertainties involved (i.e. density of unrelated products in carriers, off-carrier location within the irradiator and Cobalt-60 source decay). This issue was originally identified as part of NRC Inspection Report No. 99901445/2014-201. Nutherm International, Inc. is conducting an evaluation to determine whether a defect as defined by 10 CFR Part 21 exists. The impact of this failure to account for all uncertainties will be evaluated for all projects that required data from any sample irradiated by this supplier. 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 the requirements of 10 CFR Part 21.21. If you have any questions regarding this issue please do not hesitate to contact Adrienne Smith, Quality Assurance Manager at 618-244-6000, adrienne.smith@nutherm.com. The supplier will update this report when the evaluation is complete. This event report was originally received by the NRC Operations Center on 08/01/2014
The following information was received via fax: Nutherm has identified one customer where there is a potential impact to the conclusions of the equipment qualification that Nutherm does not have the capability to perform further evaluations to determine if a defect exists. Nutherm International, Inc. performed equipment qualification testing for SOR, Inc., Lenexa, KS under SOR, Inc. Purchase Order number 166984 which included irradiation performed by Steris Isomedix. Based on the location of the sample during the irradiation and the total variability for this location provided by Steris Isomedix, Nutherm has verified that the test specimens received a minimum irradiation dose that meets the customer's TID requirement but does not meet the customer's TID requirement with the 10 percent IEEE 323 margin. In accordance with the requirements of 10 CFR Part 21.21, SOR Inc. has been notified regarding this issue to allow them to evaluate this deviation or failure to comply. Notified the R4DO (Werner), NMSS Events Resource (via e-mail), and the Part-21 Group (via e-mail)
The following information is summarized from the information received from Nutherm International, Inc. via fax: Nutherm has completed their evaluation of past equipment qualifications and identified that the following U.S. facilities may be impacted: Cooper Nuclear Plant, Oconee Station, J.A. Fitzpatrick Station, Point Beach Nuclear, Brunswick Nuclear, Susquehanna Nuclear and Electric Power Research Institute. Nutherm has notified the affected facilities. Notified R1DO (Rogge), R2DO (Musser), R3DO (Kozak), R4DO (Pick) and the Part 21 group via email. |
