(a) Packaging (1) Model No.: NAC-LWT (2) Description The NAC-LWT is a steel-encased, lead-shielded shipping cask. The cask is designed to transport various radioactive contents as listed in 5.(b)(1). The overall dimensions of the package, with impact limiters, are 232 inches long by 65 inches in diameter. The cask body is approximately 200 inches in length and 44 inches in diameter. The cask cavity is 178 inches long and 13.4 inches in diameter. The volume of the cavity is approximately 14.5 cubic feet.

The cask body consists of a 0.75-inch-thick stainless steel inner shell, a 5.75-inch-thick lead gamma shield, a 1.2-inch-thick stainless steel outer shell, and a neutron shield tank. The inner and outer shells are welded to a 4-inch-thick stainless steel bottom end forging. The cask bottom consists of a 3-inch-thick, 20.75-inch-diameter lead disk enclosed by a 3.5-inch-thick stainless steel plate and bottom end forging. The cask lid is 11.3-inch-thick stainless steel stepped design, secured to a 14.25-inch-thick ring forging with twelve 1-inch diameter bolts. The cask seal is a metallic O-ring. A second teflon O-ring and a test port are provided to leak test the seal. Other penetrations in the cask cavity include the fill and drain ports, which are sealed with port covers and O-rings.

The neutron shield tank consists of a 0.24-inch-thick stainless steel shell with 0.50-inch-thick end plates. The neutron shield region is 164 inches long and 5 inches thick. The neutron shield tank contains an ethylene glycol/water solution that is 1% boron by weight.

The cask is equipped with aluminum honeycomb impact limiters. The top impact limiter has an outside diameter of 65.25 inches and a maximum thickness of 27.8 inches. The bottom impact limiter has an outside diameter of 60.25 inches and maximum thickness of 28.3 inches. Both impact limiters extend 12 inches along the side of the cask body.

The maximum weight of the package is 52,000 pounds and the maximum weight of the contents and basket is 4,000 pounds.

8. Bolt torque: The cask lids bolts must be torqued to 260 +/- 20 ft-lbs. The bolts used to secure the alternate vent and drain port covers must be torqued to 100 +/- 10 inch-lbs. The bolts used to secure the Alternate B port covers must be torqued to 285 +/- 15 inch-lbs.
9. Prior to each shipment, the package must be leak tested to 1 x 10-3 std cm3/sec, except that replaced seals must be leak tested to 2.0 x 10-7 std cm3/sec (He). Prior to first use, and at least once within the 12-month period prior to each subsequent use, the package must be leak tested to 2.0 x 10-7 std cm3/sec (He).
10. In addition to the requirements of Subpart G of 10 CFR Part 71:

(a) The metallic O-ring lid seal must be replaced prior to each shipment; and (b) Each package must meet the Acceptance Tests and Maintenance Program of Chapter 8 of the application, as supplemented; and (c) The package shall be prepared for shipment and operated in accordance with the Package Operations of Chapter 7 of the application, as supplemented. If the cask is loaded under water or water is introduced into the cask cavity, the cask must be vacuum dried as described in Chapter 7 of the application. The cask cavity must be backfilled with 1.0 atm of helium when shipping PWR or BWR assemblies, individual PWR and BWR rods, or TPBAR contents.

11. When shipping PWR, BWR, PWR MOX, MTR, DIDO assemblies, TRIGA fuel elements, TRIGA fuel cluster rods, high burnup PWR or BWR rods, GA IFM, PULSTAR fuel elements, spiral fuel assemblies, and MOATA plate bundles, the neutron shield tank must be filled with a mixture of water and ethylene glycol which will not freeze or precipitate in a temperature range from -40 °F to 250 °F.

The water and ethylene glycol mixture must contain at least 1% boron by weight.

12. A personnel barrier must be used when shipping PWR or BWR assemblies. Shipments of MTR, DIDO fuel assemblies, TRIGA fuel elements, TRIGA fuel cluster rods, high burnup PWR or BWR rods, PWR MOX rods, TPBAR contents, PULSTAR fuel elements, spiral fuel assemblies, MOATA plate bundles, or irradiated hardware must use the ISO container.
13. Packages used to ship metallic fuel rods may be shipped in a closed shipping container provided that the closed container, the cask tie-down and support system and transport vehicle (trailer) meet the applicable requirements of the Department of Transportation. When the cask is shipped in a closed shipping container, the center of gravity of the combined cask, closed shipping container and trailer must not exceed 75 inches.
14. For shipment of TPBAR contents:

(a) Prior to first use for shipment of TPBAR contents, each packaging must be hydrostatic pressure tested to 450 +15/-0 psig, as described in Section 8.1.2 of the application; (b) The package must be marked with Package Identification Number USA/9225/B(M)-96; (c) The package must be configured as shown in NAC International Drawing No. LWT 315-40-128 (Sheets 1-2), for the applicable TPBAR contents; and (d) Prior to each shipment, after loading, each cask containment seal must be tested to show no leakage greater than 2 x 10-7 std-cm3/s (helium).

15. For shipment of PULSTAR fuel:

(a) Intact fuel elements may be configured as PULSTAR fuel assemblies, may be placed into a TRIGA fuel rod insert (a 4 x 4 rod holder), or may be loaded into PULSTAR fuel cans. Intact PULSTAR fuel assemblies and PULSTAR fuel elements in a TRIGA fuel rod insert may be loaded in any module of the 28 MTR basket assembly. PULSTAR fuel cans may only be loaded into the top or base module of the 28 MTR basket assembly.

(b) Damaged PULSTAR fuel elements and nonfuel components of PULSTAR fuel assemblies must be loaded into PULSTAR cans. Damaged PULSTAR fuel, including fuel debris, pellets or pieces, may be placed in an encapsulating rod prior to loading into a PULSTAR fuel can.

PULSTAR fuel cans may only be loaded into the top or base module of the 28 MTR basket assembly.

(c) Loading of modules with mixed PULSTAR payload configuration is allowed.

16. For shipment of HEUNL contents:

(a) Hydrogen concentration can be assumed to be less than 5% provided the package shipment is completed within 3 months of closure of the HEUNL containers.

(b) The maximum cumulative time (service life) an HEUNL container shall contain the HEUNL solution is 15 months.

(c) An HEUNL container that has a cumulative time containing HEUNL solution greater than 12 months is not authorized to be loaded with HEUNL solution.

17. For shipment of NRU\NRX Fuel:

NRU/NRX basket weldment serial numbers (S/N's) 315-391-173-01 and -03 through -06 are authorized for use with exception to the requirement presented in License Drawing No. LWT 315-40-173, Rev. 2, (sheets 1-2) note No. 8. No other NRU/NRX basket weldments are authorized for use with exception to note No. 8, other than the S/Ns specified in this condition.

18. For shipment of non-fissile contents, with fissile content in the package not exceeding Type A quantity, and qualifying as a fissile exempt quantity under 10 CFR 71.15, the Model No. NAC-LWT shall be designated as Type B(U)F-96, with package identification number USA/9225/B(U)-96.
19. Transport by air is not authorized.
20. Revision 70 of this certificate may be used until March 31, 2022.
