In accordance with 10 CFR 71.31, TN Americas LLC (TN) made a submission of an application to revise Certificate of Compliance (CoC) No. 9313 for the TN-40 packaging [1]. TN is providing a supplement to revise the requirement for performing leak test of the containment system as part of routine determinations before each shipment. provides a summary of this change to the Safety Analysis Report (SAR).
Changes to the Safety Analysis Report (SAR) are provided as Revision 17C in. SAR Revision 17C changes are indicated by italicized text and revision bars and, additionally, are gray shaded to distinguish them from Revision 17A and Revision 17 B changes. A consolidated SAR Revision 17 will be submitted upon completion of the NRC review.
The NRC Electronic Information Exchange (EIE) system is used for submission of this supplement to the application.

Summary of Changes to E-62829 Page 1 of 1 This enclosure is intended to provide a summary of the proposed changes to assist in understanding the revision of the affected sections of the safety analysis report (SAR).
There is one change proposed to the SAR, as described below. The change is described, a justification for the change is provided, and the section of the SAR that is impacted is identified in this summary. Changed pages are annotated with revision markings.
- 1.
Clarification of the conditions when a pre-shipment leak test is not required
==
Description:==
Page 7-3 of the TN-40 SAR Revision 17C has been modified to allow the user to not perform the pre-shipment leak test in the case where the lid bolts were replaced one at a time as required in Section 7.1.3, Step 4.
Justification:
It is shown in Calculation 10421-064 that replacing the lid bolts one at a time does not perturb the lid seal and does not cause a loss of sealing. Therefore, per ANSI N14.5, if the seal has not been perturbed, the pre-shipment leak test is not required.
Impact:
SAR Chapter 7, page 7-3 has been updated to include the change described.

- 5. Visually inspect accessible surfaces of the cask for evidence of cracks, corrosion, dents, or other degradation.
- 6. Verify that radiation and contamination levels are in accordance with the site requirements to minimize worker exposure. Also check surface contamination levels to verify that they meet the requirements of 49 CFR 173.443 [8] and 10 CFR 71.87 [6].
NOTE:
A periodic leakage rate test, as described in Section 8.2.2, shall be performed within 12 months prior to shipment. The pre-shipment leak test is not required if there has been no disassembly of the lid, vent port cover, or drain port cover, or loosening of any closure bolts (except as covered under Section 7.1.3, Step
- 4) since the periodic leakage rate test was last performed.
- 7. Perform a pre-shipment leak test of the lid, vent port cover, and drain port cover seals in accordance with ANSI N14.5 [1]. The combined standard leak rate shall be less than 1.0 x 10-4 ref cm3/s with a test sensitivity of at least 5.0 x 10-5 ref cm3/s, or no detectable leakage when tested to a sensitivity of at least 1.0 x 10-3 ref cm3/s.
- 8. Replace the storage OP port cover with the transport OP port cover.
CAUTION:
Lower trunnions shall not be used as a lifting attachment point.
- 9. Place cask on the transport frame, as follows:
a) Move the transport vehicle with transport frame in place into the loading area and prepare to down end the cask.
b) Attach the lift beam to the cask handling crane hook, and then engage the lift beam to the two upper (top) trunnions.
c) Lift the cask and place the rear trunnions on the rear trunnion supports of a separate down ending frame or the transport frame.
d) Rotate the cask from the vertical to the horizontal position. Skip Step 8.e) if the cask is on the transport frame.
e) Using a spreader bar and lifting straps, lift the cask from the down ending frame and lower it onto the transport frame.
- 10. Install the tie-down straps.
- 11. Install the impact limiters (ILs), as follows.
a) Prior to installing the ILs, inspect them visually for damage. The ILs may not be used without repair if any wood has been exposed.
b) Install the top IL spacer on the front end (lid end) of the cask.
c) Install the front (top) and the rear (bottom) ILs onto the cask.
