SAFETY EVALUATION REPORT Docket No. 71-9356 Model No. MAGNATRAN Package Certificate of Compliance No. 9356 Revision No. 1
SUMMARY
By application dated July 1, 2019 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML19186A385), as supplemented on July 15, 2019 (ADAMS Accession No. ML19203A252), and August 7, 2019 (ADAMS Accession No. ML19221B591),
NAC International, Inc., (NAC or the applicant) submitted a consolidated application for Certificate of Compliance No. 9356, for the Model No. MAGNATRAN package. NAC requested that the consolidated application, which corresponded to Revision 0 of the certificate of compliance for the MAGNATRAN transportation package be added to the certificate of compliance. NAC submitted the consolidated application to incorporate the safety analysis report and all supplements for the initial issuance of the certificate of compliance. While NAC did not request any changes to the package design or authorized contents in the consolidated safety analysis report (SAR), NAC did request an editorial correction in Table 8.1-1.
EVALUATION In the consolidated SAR, NAC incorporated all supplements previously approved by U.S.
Nuclear Regulatory Commission (NRC). The staff also reviewed the operating and maintenance procedures for the package and found them to be adequate.
In its application dated November 26, 2012, as supplemented, NAC performed a criticality analysis for PWR baskets and took 90% credit for the 10B in the borated aluminum alloy and borated MMC plates. The effective 10B density (90% of actual 10B density) that was used in the criticality evaluation was 0.036 g/cm2, 0.030 g/cm2, and 0.027 g/cm2 to ensure criticality safety.
Table 8.1-1, Neutron Absorber Material Minimum 10B Loading, which provides both the minimum neutron absorber actual areal density and minimum effective areal density for performing the acceptance test incorrectly listed the effective areal density for borated aluminum alloy and borated MMC as 0.334 10B g/cm2 instead of 0.0334 10B g/cm2, for pressurized-water reactor (PWR) fuel. All the values for boiling-water reactor (BWR) fuel were correct.
Since the NAC criticality evaluation and the NRC staffs safety evaluation report (ADAMS Accession No. ML19105A148) both indicate that the effective areal density used was 0.030 10B g/cm2, and that it should be 90% of the actual areal density, the NRC staff concludes that the two values stipulated in Table 8.1-1 of 0.334 10B g/cm2 is a typographical error and should be 0.0334 10B g/cm2. The values shown in the table below are correct and are reflected in the August 7, 2019, supplement.

The consolidated application date was added to item 3(b) and the REFERENCES section.
The References was updated to include the supplements dated July 15 and August 7, 2019.
CONCLUSION These changes do not affect the ability of the package to meet the requirements of 10 CFR Part 71.
Issued with Certificate of Compliance No. 9356, Revision No. 1.
