Areas Inspected: A special inspection of the records of a spent fuel shipping cask was performed in response to a request from the transportation branch.
The inspection involved thirty-two (32) inspector hours on site by one NRC inspector.
Results: No deviations or unresolved items were identified.
Other Significant Findings: Transnuclear, Inc., (TNY) has identified that Transuucleaire (TNP) is the cask designer and Robatel is t.se fabricator of the TN-8 and TN-9 spent fuel casks. One TN-9 cask is in domestic use currently.
Transnuclear (TNY) har committed to comply with the Quality Assurance require-ments of Appendix E to 10 CFR 71.
Cask serial number TN-9.1 was fabricated at Robatel during 1977 to the requirements of Appendix E as invoked by procure-ment documents from Transnuclear (TNY).

Records Review 1.
Background Information Recent findings indicate that some spent fuel shinping casks are not in conformance with their Certificates of Compliance. An audit of the manufacturing records was requested. The memo concerning this item requests that the fabrication records be reviewed to establish whether objective evidence exists that will demonstrate that the casks were built, inspected, and tested, it. iccordance with approved drawings and with the Certificates of Con
.tance.
2.
Objectives The objectives were to verify that the fabrication records, demon-strate that the ' spent fuel shipping casks were manufactured and tested in conformance with their Certificates of Compliance and approved drawings. Also that all repair and rework performed were verified as having been properly evaluated and approved, and any deviations from the Certificate were properly reviewed and approved and such approval documented.
3.
Method of Accomplishment The preceding objectives were accomplished by:
Review of the Transnucleaire (TNP) design specification, and a.
drawings. Also review of the Transnuclear (TNY) Certificate of Compliance, Safety Analysis Report for TN-8 and TN-9 and the drawing submitted to the NRC.
b.
Review of the Transnuclear (TNY) data files on the Cask TN-9.1 to ascertain whether the files included records of the accep-tance test reports (hydro, thermal, load, etc.).
In particular the acceptance criteria used, test instrument sensitivity, cali-bration for the hydro testing was checked. The minimum sensitivity of the leakage test was confirmed. The gauge sensitivity and the acceptance criteria used for thermal testing was certified. The test forces and gage accuracy were verified for the load tests.

2 Ine certified material test reports for a sample of approxi-mately twenty three (23) components were reviewed.
In partic-lar compliance with the material requirements stated in tha Safety Analysis Report i.e. tensile strength, yield strength, and elongation.
The Receiving Inspection Reports of the above sample of com-ponents were reviewed. The dimensional acceptance were veri-fied on a sample of approximately fourteen (14) dimensions found on the drawing no. 9317.03 referenced on the Certificate of Compliance.
Nondestructive examination reports and weld inspection reports were reviewed for a sample of approximately twenty (20) welds.
In specific it was verified that all required tests were docu-merted and that welding was properly performed.
All Deviations and nonconformance reports were reviewed. All these reports were verified to have been reviewed properly and accepted. Approximately fifty (50) reports were found and re-viewed. view of the Transnuclear (TNY) data files on cask TN-9.1 and verify that the files included such items as acceptance test reports (hydro, thermal, load, etc.), certified material test reports, inspection reports (receiving, inprocess and final),
nondestructive examination reports, test reports, weld inspection reports, deviations, nonconformance reports and drawings.

Findings a.
Deviation None.
b.
Unresolved Item None.
