Model No. PAT-1 Shipping Container USA /0361/B( )F ADDENDUM NO.1 TO THE SAFETY EVALUATION BY THE TRANSPORTATION CERTIFICATION BRANCH FOR THE MODEL N0. PAT-1 SHIPPING CONTAINER, NUREG-0361, DATED JUNE 1978 Encl to ltr dtd APR 2 3 1988 By application dated February 20, 1980, Sandia Laboratories, Albuquerque, New Mexico, requested an amendment to NRC Certificate of Compliance No. 0361 for tne Model No. PAT-1 shipping container.
The application requested modifica-tion of the authorized contents to pennit shipment of larger amounts of bagging and inert packaging material when less than 200 grams of radioactive material are transported in the package. The specific changes are as follows:
1.
Maximum 200 grams total radioactive material, the type and form of material to be as previously authorized for the package.
2.
Maximum one gram of water.
3.
Maximum 200 grams of metal.anning material (in addition to the PC-1 product can, Drawing No. ".02.4).
4.
Maximum 64 grams of aluminum foil or honeycomb material (in addition to the top spacer, Drawing No.1015).
5.
Maximum 175 grams of glass.'
6.
Nximum 35 grams of polyethylene or polyvinylchloride bagging material.
With these changes,Mthe total weight of the contents and the total weight of the package will not exceed the values considered in the original safety evaluation. The physical condition and structural integrity of the package, following the tests specified in 10 CFR Part 71 and in NUREG-0360, will be the same as previously considered.
The maximum quantity of radioactive material will be less than previously approved. The maximum pressure in the containment ' vessel under the normal and accident conditions in 10 CFR Part 71 and under the qualification tests in NUREG-0360 will not exceed the peak values considered in the original safety evaluation. Also, the time-history of pressure within the containment vessel following the one-hour fire test will be within the bounds considered in the original safety l
evaluation. Therefore, the maximum quantity of material that could L' released from the containment vessel, integrated over a one week perica following the accident tests specified in NUREG-0360, will be no more than previously estimated and will be within allowable limits.
l
In addition to the modifications requested in the Sandia Laboratories application, three other changes have been incorporated into the revised Certificate of Compliance:
1.
The additional permissible contents of "two single-layer polyethylene bags" has been changed to a maximum of 10 grams of polyethylene or polyvinylchloride bagging material.
This change more precisely quantifies the amount of bagging material that may be used and authorizes use of polyvinylchloride as an alternative to polyethylene.
The 10 gram limit corresponds to the mass of decomposable material considered in the original safety evaluation. With these changes, the pressure in the containment vessel will not exceed the values considered previously.
2.
The authorized contents have been revised to include mixtures of enriched uranium oxide as well as mixtures of ~ natural or depleted uranium oxide that were previously huthorized.
The staff has determined that contents which include mixtures of enriched uranium oxide will be no more reactive than the contents considered in the original safety evaluation.
Including enriched uranium oxide as authorized contents does not affect the ability of the package to meet the containment requirements specified in 10 CFR Part 71 and in NUREG-0360.
3.
A license condition has been added to. clarify that the PC-1 product can (Drawing No.1024) and the top spacer (Drawing No.1015) are not i
required when less than 20 curies of plutonium are being transported in the package.
This change clarifies the applicability of 10 CFR 571.42(b) to the use of the Model No. PAT-1 package when the contents include 'as than 20, curies of plutonium.
Based upon the foregoing, the staff has determined that its initial safety findings have not been invalidated and the Model No. PAT-1 package authorized by NRC Certificate of Compliance No. 0361, Revision 1 meets the requirements specified in 10 CFR Part 71 and in NUREG-0360.
