SUBJECT:

Written report, in accordance with 10 CFR 71.1, as required by 10 CFR 71.95(b)

[forNRC Docket 91-934 1] regarding conditions in the Certificate of Compliance for theBEA Research Reactor Package that were not met during shipment

Dear Sir or Madam,

The University of Missouri Research Reactor (MURR) submits this letter to report a condition pursuant to10 CFR 71.95(b) regarding the use of the BEA Research Reactor (BRR) Package, NRC Docket 71-9341.The following is a description of the event, reported in accordance with 10 CFR 71.95(c):

(1) Brief abstract of the eventDuring 7 shipments of irradiated research reactor fuel between Columbia, MO and the Savannah RiverSite (SRS) between October 2011 and May 2013, the conditions contained in Section 5.(a)(3) of theCertificate of Compliance (CoC) were not met in their entirety.

Specifically, a part supplied by thecertificate holder, the alignment pin between the cask body and the closure lid, was not made of thematerial specified on the General Arrangement Drawings referenced in the CoC. To correct this situation, the certificate holder is ensuring a new alignment pin is being fabricated to the specifications of the CoC.Until the new pin is installed, the cask has been removed from service.(2) Narrative description of the eventOn March 10, 2014, MURR was notified by a representative of Idaho National Laboratory (INL) that thepart known as the alignment pin had originally been fabricated using a material not approved in thecertificate (NRC Certificate of Compliance 71-9341).

This fabrication error was attributed to atypographical error on the package as-built drawings.

A1513 Research Park Drive Columbia, MO 65211 Phone: 573-882-4211 Fax: 573-882-6360 Web: www.murr.missouri.edu Fighting Cancer with Tomorrow's Technology Apr 14, 2014MURR, Docket 50-186The purpose of the pin is to align the bolt holes in the closure lid with the threaded holes in the cask bodyduring installation of the lid. Per the certificate holder's documentation, the pin has no safety function andhas therefore been categorized as Quality Category C. The material of the pin is specified in the List ofMaterials of drawing 1910-01-01-SAR, Revision 4, as ASTM A276, UNS 21800. The actual materialused for the pin was Type 304 stainless steel. All other requirements of the CoC were met by the subjectshipments.

The original alignment pin had been installed on the package by the manufacturer and was in place uponMURR's original receipt of the package.

The package was used by MURR in this configuration during 2shipments between October 2011 and April 2012. Subsequently, the pin failed at another user's site andwas replaced using a part fabricated at MJURR, per the certificate holder's instructions, from 304 stainless steel. Installation of the pin was performed at the other user's site, and the package has been used byMURR in this configuration during 5 shipments between April 2012 and May 2013.For all shipments of the packaging from MURR, the payload consisted of up to eight irradiated aluminumplate-type research reactor fuel elements.

A detailed description of the irradiated fuel is given in Section1.2.2.1 of the BRR Package Safety Analysis Report.(3) Assessment of safety consequences of the eventSince the alignment pin does not perform a safety function, there were no safety consequences of theevent. The alignment pin continued to perform its alignment

function, even though made of the wrongmaterial.

(4) Description of corrective actionsAs noted above, the packaging has been taken out of service until the alignment pin can be replaced inaccordance with the certificate holder's Quality Assurance Program and procedures.

Since the alignment pin is threaded in place, replacement may be readily performed.

The certificate holder, AREVA Federal Services LLC, has opened a Corrective Action Report (CAR) in accordance withtheir 10 CFR 71 Subpart H Quality Assurance Program and procedures, and has performed a completereconciliation between the licensing drawings and the fabrication drawings to ensure that all othercomponents have been fabricated in full compliance with the licensing drawings.

A more completedescription of corrective actions taken by the certificate holder may be obtained from AREVA.MURR has initiated a Corrective Action Program (CAP) item, CAP 14-0023, to document the issue andwill review the certificate holder's corrective actions and NRC resolution of the issues prior to using thecask.(5) Reference to similar eventsBy letter dated March 23, 2012, MURR notified the NRC of performing two shipments using the BRRPackage in the fall of 2011 with an incorrect drain port sealing washer installed.

This sealing washer wasincorrectly specified in the package documentation; therefore, the incorrect part had been supplied by themanufacturer with the cask. A similar issue was experienced at the Massachusetts Institute of Technology Page 2 of 3 Apr 14, 2014MURR, Docket 50-186(MIT) Nuclear Reactor Laboratory in November 2011, as indicated in their letters to the NRC datedJanuary 25 and February 3, 2012.(6) Licensee contactFor further discussion of this incident, please contact John Ernst, Associate Director for Health andSafety, at 573-882-5226 or emstj@missouri.edu.

(7) Extent of exposure of individuals There was no exposure to individuals as a result of this event.I declare under penalty of perjury that the foregoing is true and correct.Sincerely, 0:ýRalph A.
