Subject:
Interim Report -10CFR Part 21 Evaluation Regarding Potential DeficienciesThe purpose of this letter is to provide the NRC a report in general conformity to therequirements of 1 OCFR Part 21.21 (a)(2).Preferred Metal Technologies (PMT) was notified by Steris Isomedix Services that the appliedradiation dose reported on their Component Irradiation Certificates did not account for all theuncertainties involved (i.e. density of unrelated products in carriers, off-carrier location within theirradiator and Cobalt-60 source decay). This potential defect was originally identified as part ofNRC Inspection Report No. 99901445/2014-201.Required information as per 1 OCFR Part 21.21 (d)(4) follows:(i) Name and Address of the individual or individuals informing the Commission:Tim Stewart, Vice President NuclearPreferred Metal Technologies, Inc.140 East Tower DriveBurr Ridge, Illinois 60527(ii) Identification of the facility, the activity, or the basic component supplied for suchfacility or such activity within the United States which fails to comply or contains adefect:The Radiation Qualification of the following basic components is affected by thisdiscrepancy:(a) Electric Spring Return Actuator, PC # T-7360 (PMT Project No. N1839)(b) Various non-metallic materials (Gasket PC # T-7621, Bearings PC # T-7597,Seal PC # T-6669 and Adhesive PC # T-7594) utilized as part of a completedamper assembly (PMT Project No. N1893)Refer to section (vi) of this letter for specific project details.140 E.

This evaluation was performed as a result of an NRCInspection of the Steris Isomedix Services facility in Whippany, NJ. Thisevaluation determined that the actual dose delivered may have differedup to +/-5.1% from that value reported on their Component IrradiationCertificate depending on the location within the irradiator where thecomponent was processed. The worse case variability (+/-5.1%) is basedon the density variation, source decay and intercomparison variability.This variance is in addition to the standard uncertainty of the dosimetrysystem (+/-6.5%). As a result, there is a potential safety hazard that thebasic components supplied by PMT may not be qualified for operation atthe postulated radiation levels that may occur during an accident.(v) The date on which the information such defect or failure to comply was obtained:Notification was received on the afternoon of June 23, 2014(vi) In the case of a basic component which contains a defect or fails to comply, thenumber and location of these components in use at, supplied for, being supplied for, ormay be supplied for, manufactured or being manufactured for one or more facilities oractivities subject to the regulations in this Part:After a thorough review of all purchase orders issued to Steris IsomedixServices and PMT Projects that the irradiation test results were utilizedon, PMT has determined that there are two projects where the appliedradiation dose may have failed to meet the minimum required radiationdose to ensure that the safety related equipment would continue tooperate satisfactorily during / after an accident. The details of those twoprojects are as follows:140 E. Tower Drive -Burr Ridge, II1., 60527 -Phone 630.887.7700 -Fax 630.887.0770

Concurrent with this notificationto the NRC, PMT is providing notification of this failure to comply to theaffected Owners. PMT Engineering will determine and implement asupplemental test program on the original qualification components suchthat the minimum dose applied meets or exceeds the originalenvironmental qualification requirements contained within the Owner'spurchase order. Affected documents (e.g. EQ reports) will besupplemented or revised as applicable. PMT will review the supplierrestrictions imposed on Steris Isomedix Services for inclusion ofadditional requirements to prevent recurrence. Final corrective actions tobe implemented will be as specified within the PMT disposition to CARNo. 64 and will be documented within the Final Part 21 Report issued toNRC. Final closure of CAR No. 64 is targeted for the week of August 4,2014.(viii) Any advice related to the defect or failure to comply about the facility, activity, or basiccomponent that has been, is being, or will be given to purchasers or licensees:Each owner / utility will need to review the radiation dose applied, takeinto account the applicable reduction due to the reported variance, andthen evaluate whether or not the environmental qualification testingperformed still envelopes the minimum requirements for the application.(ix) In the case of an early site permit, the entities to whom as early site permit wastransferred:Not Applicable140 E.
