SUBJECT:
APPLICATION FOR MODEL 1100 - SUPPLEMENTAL INFORMATION NEEDED
- ENTERPRISE PROJECT IDENTIFICATION NUMBER L-2024-NEW-0010
Dear Lori Podolak:
By letter dated October 3, 2024 (Agencywide Documents Access and Management System
[ADAM] Accession No. ML24284A277), QSA Global has submitted an initial application for the Model 1100 transportation package design to the U.S Nuclear Regulatory Commission (NRC) for review.
The NRC staff performed an acceptance review of the application to determine if the application contains sufficient technical information in scope and depth to allow the staff to complete the detailed technical review. This letter is to advise you that, based on our acceptance review, the application does not contain sufficient technical information. The information needed to continue our review is described in the enclosed request for supplemental information (RSI) to this letter.
In order to schedule our technical review, responses to the enclosed RSI should be provided within 30 days from the date of this letter. If QSA Global is unable to meet this response date, please notify us at least 2 weeks in advance of your new submittal date and the reasons for the delay. If QSA Global is not able to respond within this timeframe or the RSI responses provided to the NRC do not provide sufficient information, the application may not be accepted for review.
In accordance with Title 10 of the Code of Federal Regulations Part 2, Agency Rules of Practice and Procedure, a copy of this letter will be available electronically for public inspection in the NRC Public Document Room (PDR) or from the Publicly Available Records component of the NRCs ADAMS. ADAMS is accessible from the NRC website at http://www.nrc.gov/reading-rm/adams.html. The PDR is open by appointment. To make an appointment to visit the PDR, February 10, 2025
L. Podolak 2
please send an email to PDR.Resource@nrc.gov or call 1-800-397-4209 or 301-415-4737, between 8 a.m. and 4 p.m. eastern time (ET), Monday through Friday, except Federal holidays.

Enclosure Request for Supplemental Information Certificate of Compliance No. 9405 Docket No. 71-9405 Revision 0 The question below describes information needed by the staff for it to begin its review of the application and to determine whether the applicant has demonstrated compliance with regulatory requirements.
Thermal Review RAI-Th-1:
Provide a calculation that demonstrates the integrity of the Ir-192 source capsule and Se-75 source capsule that is transported inside the QSA Model 1100 would be maintained during and after the fire hypothetical accident conditions (HAC).
SAR section 2.7.4 and section 3.5 (which referenced the Model 865 package) discussed the impact of the fire HAC on the packages internal shielding material based on results of previous test programs. However, there was no analysis that demonstrated the material, material thickness, and construction methods (e.g., weld fabrication) of the special form capsules that contain the 150 Ci Ir-192 source or the 150 Ci Se-75 source loaded within the Model 1100 could withstand the effects of a 30 minute 800 °C environment and the resulting increased internal pressure. Staff notes that a similar calculation based on a steady-state 800 °C temperature was provided in a previous QSA Model 865 application (note that references of some parameters used in the Model 865 calculation would help to provide context).
This information is needed to determine compliance with Title 10 of the Code of Federal Regulations 71.51.
