RNDISRIUION NMSS-2002-A-0002 Page 1 ALLEGATION REVIEW BOARD
SUMMARY
Allegation: NMSS-2002-A-0002 U. S. Tool & Die Holtec Commonwealth Edison/Dresden
- 1. The NMSS Allegation Review Board met on April 4,2002, at 9:00 a.m. in O-13D22
- 2. Present at the meeting were:
E. W. Brach, Dir. SFPO, Chairman P. P. Narbut, SFPO R. L. O'Connell, OAC E. P. Wilson, 01
- 3. Facilities involved: U. S. Tool & Die, Holtec, Excelon (ComEd), Dresden site
- 4. Concerns:
- 1.
The Concerned Individual (Cl) stated that a vendor [U.S. Tool & Die] modified spent fuel storage casks during the fabrication process by making repairs and/or accepted discrepancies "as is" without obtaining the required review and approval of the cask designer [Holtec]. Cl is concerned that this was contrary to Excelon's (ComEd) procedures.
- 2.
Cl is concerned about the Inadequate QAQC oversight by the spent fuel storage cask design organization [Holtec] over the spent fuel storage cask fabricator [U.S. Tool &
Die] and that this inadequate oversight has resulted In Indeterminate quality and the structural integrity of the casks Is suspect. Cl stated that the fabricator's disposition of nonconformance condition as "use-as-ls," "rework," and "repair" was a violation of the QA program for design control as specified in 10 CFR 71 and 10 CFR 72. Cl stated that "use-as-is" and "repair" dispositions are design changes and should be evaluated and documented by engineering analysis. In addition, the fabricator dispositioned many nonconformance conditions under its QA program without the design organization's consent.
- 5. Safety significance: Medium Basis: If technically inadequate changes were made to the casks fabricated and delivered to_
licensees for spent fuel storage, then inadequate casks may be loaded with spent fuel and there may be a potential for release or accelerated fuel degradation. Also the internal spent fuel canisters may be used later in transportation containers for shipment to other repositories, posing a potential transportation risk.

- 8. The following resolution plan & schedule was approved by the ARB:
Transfer of two concerns from RilI-2002-A-0005. ARB was briefed on the background of the concerns by Paul Narbut. His review of the file indicated that the alleger's description of the allegation also included: "....ComEd should have documentation of their review of the dry cask storage dispositions of Use-as-is and Repair that Holtec was sending to them," and " I suspect whether [an Individual] of Holtec performed any design reconciliation and documentation for all the drycask storage containers and associated parts impacted by disposition of use-as-is, repair, and rework at UST&D that were already built and delivered to nuclear plants."
ARB noted that alleger had, in the course of a contact with SFPO management, indicated that he would be providing additional written materials. To date such nformation has not been received. OAC will send a letter to alleger asking that any such additional information be provided promptly.
ARB was advised that SFPO had conducted recent inspection at U. S. Tool & Die and found activities in this area satisfactory, but that the Inspection looked at current activities and did not look back at the period discussed by alleger.
ARB determined that allegation should be assigned to SFPOISLID for review and Inspection.
Staff will determine location of appropriate records, then will Inspect at Holtec and/or U.S. Tool
& Die as appropriate. Staff will determine the nature of the Dry Storage Quality Group (DSQG)
Audit findings at UST&D from CY 2000 related to the allegations, and will review the Holtec and.
UST&D corrective actions for adequacy of defining the extent of the condition, Immediate corrective action, and action to prevent recurrence. SFPO will conduct Inspection within 60 days.
ARB also determined that NMSS should request Rill Inspection assistance to perform an Inspection at ComEd/Dresden and determine the code and procedure requirements for reviewing and approving Supplier Deviation Requests (SDRs), and Nonconformance reports (NCRs) In regards to the obligations of the cask owner to review and approve use-as-is, and repair dispositions. Determine If ComEd Is and was complying with the requirements during the period of the allegations.
Rill will be asked to coordinate with Paul Narbut re scheduling and scope of Inspection efforts, and coordination of Rill Inspection with findings from SFPO's inspection activity.
