(a) Packaging

(1) Model No.: MAGNATRAN

(2)

Description:

The MAGNATRAN package is canister-based and is part of a dual-purpose system for the storage and transportation of spent nuclear fuel for transporting the MAGNASTOR transportable storage canister (TSC). The MAGNATRAN packaging includes the package body, upper and lower impact limiters, and TSC. The package body consists of the inner and outer shells, lead and upper forging, lid, bottom plate, bottom forging and solid neutron shield.

Leakage testing of the package containment seals, in conjunction with the post-fabrication leakage testing of the entire containment boundary, assures that the containment is leaktight. The TSC may be credited for moderator exclusion, thus serving the function of being a special design feature, as required by 10 CFR 71.55(c), that prevents a single packing error from permitting leakage into the fissile material region.

Regardless of credit applied to the TSC confinement boundary to prevent water in leakage, the containment function is retained by the transport package body.

The packaging body is a cylinder with multiwall construction consisting of inner and outer stainless steel shells separated by a lead gamma radiation shielding. The inner and outer stainless steel shells are 1.75 and 2.25 inches thick, respectively. The lead gamma shield is 3.2 inches thick. Welded above the inner and outer steel shells is the upper forging. The upper forging is 7.2 inches thick where it attaches to the inner and outer shells.

5.(a)(2) Description (continued)

The bottom of the package body consists of the bottom inner forging, the bottom outer forging and the bottom plate. The bottom inner forging is cup shaped and welded to the inner shell and the bottom forging. The ring-shaped bottom outer forging is welded to the outer shell and to the bottom plate. The bottom plate is welded onto the outer ring. The bottom inner forging is 5 inches thick and the bottom plate is 8.65 inches thick for a total of 13.65 inches of stainless steel shielding through the bottom.

The package lid is a 7.75-inch-thick stainless steel disk used to close the package. The lid is attached to the top forging by forty-eight, 2-8 UN-2A socket head cap screws. The socket head cap screws screw into the tapped holes in the upper forging. The package lid is sealed by two concentric O-rings, as is the coverplate for the lid port, using inner metallic and outer ethylene propylene diene monomer (EPDM) O-rings. The MAGNATRAN package contains a lid port that is closed by a bolted Type 304/304L stainless steel coverplate with dual O-rings. There are four stainless steel coverplate bolts. The lid port provides access to the port opening and the quick-disconnect fitting for backfilling and sampling the cavity gas during loading and unloading.

The neutron shield is comprised of NS-4-FR encased in stainless steel enclosures. The neutron shield material and its enclosure have two thicknesses, 5.8 inches and 6.4 inches, and is attached onto the outer shell along the length of the active fuel region around the circumference of the package cavity.

Two diametrically opposite lifting trunnions are bolted to the outside of the top forging to lift the transport package. Prior to transport, the lifting trunnions are removed and replaced with trunnion plugs. Two rotation trunnions are located on the outer shell near the bottom of the package to permit rotation between the horizontal and vertical positions and to provide longitudinal tiedown restraint in the aft direction. The rotation trunnions are located approximately 5 inches off the cask centerline to ensure that the cask rotates in the proper direction.

A cavity spacer is used for the short TSCs to locate and support the canister and to minimize excessive longitudinal movement in the transport cask cavity, which is sized to accommodate the long TSC.

The MAGNATRAN package has cup-shaped impact limiters, consisting of a combination of redwood and balsa wood encased in a stainless-steel shell. The impact limiters are bolted over each end of the package to limit the g-loads acting on the package during a package drop event. The impact limiters are attached to the lid and bottom plate via 16 tapped holes for retaining rods and nuts.

5.(a)(2) Description (continued)

The TSC is constructed of a stainless steel cylindrical shell, bottom-end plate, closure lid, closure ring, and redundant port covers. The TSC confines the fuel basket structure and the spent fuel or the Greater-Than-Class C (GTCC) waste basket liner and GTCC waste. The TSC cylindrical shell is dual certified 304/304L stainless steel with a 72-inch diameter and is 1/2 inch thick and either 191.8 or 184.8 inches long, depending on the contents. The bottom end plate is welded onto the lower end of the TSC shell and is 2.75 inches thick. The closure lid is 9 inches thick and is either a solid stainless steel closure lid or stainless steel/carbon steel closure lid. The closure lid is welded onto the upper end of the TSC shell. The dual port covers provide a dual-welded closure system for the vent and drain ports. The GTCC TSC is similar in design and construction to the TSCs for spent fuel, but instead of a basket, it contains a GTCC waste liner.

The PWR fuel basket design is an arrangement of 21 square, stainless steel fuel tubes held in a right-circular cylinder configuration by side and corner support weldments that are bolted to the outer fuel tubes. The 21 tubes develop 37 positions within the basket for the PWR spent fuel. Each PWR basket fuel tube has a nominal 8.86-inch square opening. Each developed cell fuel position has a nominal 8.76-inch square opening. The fuel tubes support an enclosed neutron absorber sheet on up to four interior sides of the fuel tube. Each neutron absorber sheet is covered by a thin stainless steel sheet to protect the neutron absorber during fuel loading and to keep it in position. The neutron absorber and stainless steel cover are secured to the fuel tube using weld posts distributed across the width and along the length of the fuel tube.

The PWR damaged fuel basket is designed to store up to four damaged fuel cans in the damaged fuel basket assembly in the short TSC. The damaged fuel basket assembly has a capacity of up to 37 undamaged PWR fuel assemblies, which includes the four damaged fuel can locations. A damaged fuel can may be placed in each of the four damaged fuel can basket locations. The arrangement of tubes and fuel positions is the same as in the standard fuel basket, but the design of each of the four corner support weldments is modified with additional structural support to provide an enlarged position for a damaged fuel can at the outermost corners of the fuel basket. Each damaged fuel can location has a nominal 9.80-inch square opening. A damaged fuel can, or an undamaged fuel assembly may be loaded in a damaged fuel can location.

Similar to the PWR basket, the BWR basket consists of 45 stainless steel fuel tubes that develop 87 basket locations for the BWR spent fuel. Each BWR basket fuel tube has a nominal 5.86-inch square opening. Each developed cell fuel position has a nominal 5.77-inch square opening. The BWR basket fuel tubes are held in a right-circular cylinder configuration by side and corner support weldments that are bolted to the outer fuel tubes. The fuel tubes support an enclosed neutron absorber sheet on up to four interior sides of the fuel tube for criticality control. Each neutron absorber sheet is covered by a sheet of stainless steel to protect the neutron absorber during fuel loading and to keep it in position. The neutron absorber and stainless steel cover are secured to the fuel tube using weld posts distributed across the width and along the length of the fuel tube.

5.(a)(2) Description (Continued)

The damaged fuel can confines the fuel material within the can to minimize the potential for dispersal of the fuel material into the TSC cavity. The side plates that form the upper end of the damaged fuel can are 0.15-in thick and the tube body walls are 0.048-in thick (18-gage sheet). The damaged fuel can lid plate and bottom thicknesses total 11/16 inches and the lid overall height is 2.32 inches. The damaged fuel can bottom plate thickness is 5/8 (0.625) inch. The damaged fuel can is designed in two lengths: an overall length of 166.9 inches with a nominal cavity length of 164.0 inches; or an overall length of 171.8 inches with a nominal cavity length of 169.0 inches (shorter fuel assemblies may be accommodated with a fuel assembly spacer to limit axial movement). For the shorter damaged fuel can, a spacer is used in the damaged fuel basket assembly or alternatively fixed to the damaged fuel can bottom plate to provide an overall height of 171.5 inches. The damaged fuel can (DFC) lid and bottom include screened drain holes.

The stainless steel GTCC waste basket liner is designed to hold GTCC waste and dimensionally fit in a TSC. The GTCC waste basket liner is 173 inches long with a 1-inch-thick bottom plate welded onto it. The GTCC liner stainless steel shell is 2 inches thick for structural and gamma shield functions and has lifting lugs welded on the inside diameter of the shell. The liner design also includes an outer ring and a middle support under the bottom plate and drain holes in the bottom plate to facilitate free flow drainage from the liner. The GTCC TSC includes a sump location in the bottom plate and the closure lid includes a drain tube assembly to enable draining and drying of the loaded TSC.

The package has approximate dimensions and weight as follows:

Cavity diameter 72 inches Cavity length 193 inches Package body outer diameter 87 inches Impact limiter diameter 128 inches Package length without impact limiters 214 inches with impact limiters 322 inches

The maximum gross weight of the package is about 312,000 lbs.

5.(b) Contents

(1) Type and Form of Material

(i) Undamaged PWR assemblies

Undamaged PWR fuel assemblies within the 37 PWR basket assembly. Undamaged fuel is spent nuclear fuel that does not have any visible deformation other than uniform bowing that occurs in the reactor, assemblies that do not have missing rods, and assemblies with missing rods that are replaced by solid stainless steel or zirconium filler rods that displace a volume equal to or greater than the original rods and assemblies NRC FORM 618 U.S. NUCLEAR REGULATORY COMMISSION (8-2000) 10 CFR 71 CERTIFICATE OF COMPLIANCE FOR RADIOACTIVE MATERIAL PACKAGES

that do not contain structural defects that adversely affect radiological and/or criticality safety and/or result in unsupported fuel rod lengths in excess of 60 inches and that can be handled by normal means. Undamaged PWR fuel is loaded into the short TSC, except for Combustion Engineering (CE) 16x16 fuel assemblies, which may be loaded into either length TSC.

The fuel assemblies consist of uranium dioxide pellets with zirconium alloy-clad fuel rods and zirconium alloy instrument and guide tubes. Empty fuel rod positions are to be filled with a solid filler rod or a solid neutron absorber rod. PWR fuel assemblies containing nonfuel hardware may be loaded in the TSC. Prior to irradiation, the fuel assemblies must be within the dimensions and specifications of the hybrid assemblies listed in Table 1. In addition, the PWR fuel must meet the fuel class assembly specifications listed in Table 2.

The burnup credit loading curve in Table 3, must be used for the 37 assembly loading profile. WE15x15 fuel may use the burnup credit loading curve in Table 4, with the 33, 35 or 36 assembly loading scheme provided the required cell locations for that profile shown in Figure 1 are left empty, at a minimum. Fuel assembly burnup, minimum initial average enrichment1, and cool time requirements are provided in Table 9 and Table 11, for PWR baskets with Type 2 neutron absorbers and Table 12 and Table 14 for baskets with Type 1 neutron absorbers. Burnup credit curves are only applicable to systems not crediting moderator exclusion. Initial enrichment up to 5 weight percent (wt%) in the 235U isotope, with no burnup requirement, is permitted when crediting moderator exclusion.

Unirradiated fuel and unenriched fuel are not authorized for loading, except that unenriched axial blankets are permitted, provided that the nominal length of the blanket is not greater than 6 inches. An unenriched rod may be used as a replacement rod to return a fuel assembly to an undamaged condition.

Undamaged PWR fuel assemblies may contain nonfuel hardware. Fuel assemblies with an instrument tube tie rod repair shall be loaded with fuel inserts and/or top spacers to ensure proper spacing and support of the fuel assembly. Fuel inserts and/or top spacers are not required when using the extended fuel tube basket because the top nozzle is adequately supported. The nonfuel hardware may be loaded as a complete assembly or as individual components, individual nonfuel rods may be full-length rods or partial-length rods/rodlets. Partial-length rods/rodlets are permitted in guide tubes provided guide tube plug devises are installed. Nonfuel hardware must meet the exposure and cool time or cobalt-60 activity requirements in Tables 6-8. Fuel assemblies loaded with nonfuel hardware must meet the additional cool time requirements in Table 5 (for Type 2 neutron absorbers), and Table 15 (for Type 1 neutron absorbers).

Hafnium absorber assemblies (HFRA) are only allowed for Westinghouse (WE) assemblies and may have a maximum exposure of 4.0 GWd/MTU and must have a minimum cool time of 16 years. Fuel assemblies may contain any number of unirradiated

1 Assembly average fuel enrichment is the enrichment value determined by averaging the 235U wt% enrichment over the entire fuel region (UO2) of an individual assembly, including axial blankets, if present.

nonfuel solid filler fuel replacement rods. Activated stainless steel fuel replacement rods are limited to 5 steel rods per assembly, 1 assembly per basket, and a maximum steel rod exposure of 32.5 GWd/MTU. Fuel assemblies with activated stainless steel rods must be cooled for either a minimum of 21 years or the loading table minimum cool time (as adjusted for additional cool times for nonfuel hardware, as applicable) plus 1 year, whichever is greater.

Fuel assemblies loaded with in-core instrument thimbles must meet the additional cool time requirements in Table 5 or Table 15, as appropriate, for burnable poison rod assemblies (BPRAs) or guide tube thimble plug devices (GTPDs), whichever is bounding, for Westinghouse and Babcock and Wilcox (B&W) fuel types and for reactor control components (RCCs) for CE fuel types. The additional cool time requirements for assemblies with nonfuel hardware are added to any additional cool time requirements due to damaged fuel also being loaded in the same TSC. RCCs are restricted to fuel storage locations 11, 12, 13, 18, 19, 20, 25, 26 and 27 in Figure 1. Only one neutron source assembly (NSA) is permitted to be loaded in a TSC in fuel storage locations 11, 12, 13, 18, 19, 20, 25, 26 or 27, as shown on Figure 1.

NSAs may contain source rods attached to hardware similar in configuration to guide tube plug devices (thimble plugs) and burnable absorbers, in addition to containing burnable poison rodlets and/or thimble plug rodlets. NSAs, GTPDs, and BPRAs are not authorized for CE fuel assemblies. In addition, the following un-irradiated nonfuel hardware may be loaded with the fuel assemblies: stainless steel rods inserted to displace guide tube dashpot water, instrument tube tie components, and guide tube anchors or similar devices. Axial power shaping rods are not allowed contents.

Under-burned Westinghouse 15x15 assemblies (assemblies with a maximum enrichment greater than that dictated by the burnup credit loading curve) may be loaded provided that a RCCA is inserted in the assembly, the enrichment is equal to or less than 4.05 wt. % 235U, and the assembly burnup is greater than or equal to 12,000 MWd/MTU.

When loading under-burned fuel, the RCCAs must be full-length Ag-In-Cd RCCAs comprised of stainless steel clad rods constructed with 80% Ag, 15% In and 5% Cd absorber pellets and having an exposure equal to or less than 200,000 MWd/MTU. The basket must include absorber sheets with an effective 10B areal density of 0.036 g/cm2.

Any assemblies loaded without an RCCA inserted must meet the burnup credit loading curve for the applicable assembly loading profile. Burnup credit curves, and the criticality need for RCCA insertion are only applicable to systems not crediting moderator exclusion. Initial enrichment up to 5 wt% 235U, with no burnup requirement, is permitted when crediting moderator exclusion.

(ii) Undamaged and damaged PWR assemblies

A combination of damaged and undamaged PWR fuel assemblies in the 37 PWR damaged fuel basket, shown in Figure 2, in a short TSC. Undamaged, low burnup fuel assemblies must meet the description for PWR fuel in 5.(b)(1)(i). Up to four damaged fuel assemblies, or fuel material that is less than, or equivalent to, one undamaged PWR fuel assembly must be placed in a damaged fuel can and must be placed in locations 4, 8, 30 and 34 in the PWR damaged fuel basket. Undamaged, low burnup fuel may also be placed in the 4 damaged fuel locations, without the use of a damaged fuel can. Prior to irradiation, the damaged and undamaged fuel assemblies must be within the dimensions and specifications of the hybrid assemblies listed in Table 1 and meet the fuel class assembly specifications listed in Table 2.

For the 33 non-damaged fuel can locations in the damaged fuel basket, the fuel must meet the class enrichment, post-irradiation cooling time, burnup credit loading curves, and the TSC neutron absorber sheet 10B density in Table 16. For the loading profiles up to the 33, 35 and 36 assembly loading pattern, the PWR fuel must meet the burnup loading curves in Table 17. A short-loaded 33, 35 or 36 assembly loading profile may still use the burnup credit curve in Table 17 provided the required cell locations for that profile shown in Figure 1 are left empty, at a minimum. For a TSC with a damaged fuel basket assembly that does not contain any damaged fuel, the fuel class enrichment, post-irradiation cooling time, burnup credit loading curves, and the TSC neutron absorber sheet 10B density in Tables 3 and 4 may be used for all locations (burnup credit curves are only applicable to systems not crediting moderator exclusion).

Fuel assembly burnup, minimum initial average enrichment9, and cool time requirements are provided in Tables 9-11 for PWR baskets with Type 2 neutron absorbers and Tables 12-14 for baskets with Type 1 neutron absorbers. For TSCs containing damaged fuel, all fuel assemblies in the TSC must meet the additional cool time requirements in Table 18 for the assembly type that is loaded in the damaged fuel can. If two types of fuel assemblies are loaded in different damaged fuel cans in a single TSC, the longest additional fuel cooling time applies to all fuel assemblies in the TSC. The additional cool time requirements in Table 18 apply to assemblies loaded in TSC baskets with Type 1 or Type 2 neutron absorbers. Damaged CE 16x16 fuel assemblies are not authorized for shipment.

The fuel assemblies consist of uranium dioxide pellets with zirconium alloy-clad fuel rods and zirconium alloy instrument and guide tubes. Empty fuel rod positions for undamaged fuel assemblies are to be filled with a solid filler rod or a solid neutron absorber rod that displaces a volume equal to or greater than the original rod. PWR fuel assemblies containing nonfuel hardware may be loaded in the TSC.

9 Assembly average fuel enrichment is the enrichment value determined by averaging the 235U wt% enrichment over the entire fuel region (UO2) of an individual assembly, including axial blankets, if present.

Unirradiated fuel and unenriched fuel are not authorized for loading, except that unenriched axial blankets are permitted, provided that the nominal length of the blanket is not greater than 6 inches. An unenriched rod may be used as a replacement rod to return a fuel assembly to an undamaged condition. Damaged fuel located in a damaged fuel can location in the damaged fuel basket must have a minimum burnup of 5 GWd/MTU, a maximum enrichment of 4.05 wt. % 235U, and a minimum cool time of 15 years. PWR fuel assemblies loaded in a damaged fuel can must not contain nonfuel hardware with the exception of instrument tube tie components, guide tube anchors or similar devices, and steel inserts. Application of moderator exclusion allows increasing the maximum initial enrichment to 5 wt% 235U, with no burnup requirement.

Undamaged PWR fuel assemblies may contain nonfuel hardware, while damaged PWR fuel assemblies shall not, with the exception of the following unirradiated nonfuel hardware:

instrument tube tie components, guide tube anchors or similar devices, and steel inserts.

The nonfuel hardware may be loaded as a complete assembly or as individual components, individual nonfuel rods may be full-length rods or partial-length rods/rodlets. Partial-length rods/rodlets are permitted in guide tubes provided guide tube plug devises are installed. Fuel assemblies with an instrument tube tie rod repair shall be loaded with fuel inserts and/or top spacers to ensure proper spacing and support of the fuel assembly. Fuel inserts and/or top spacers are not required when using the extended fuel tube basket because the top nozzle is adequately supported. Nonfuel hardware must meet the exposure and cool time or cobalt-60 activity requirements listed in Tables 6-8.

HFRAs are only allowed for Westinghouse assemblies and may have a maximum exposure of 4.0 GWd/MTU and must have a minimum cool time of 16 years. Fuel assemblies loaded with nonfuel hardware must meet the additional cool time requirements of Table 5 (for Type 2 neutron absorbers), and Table 15 (for Type 1 neutron absorbers). Fuel assemblies may contain any number of unirradiated nonfuel solid filler fuel replacement rods. Activated stainless steel fuel replacement rods are limited to 5 steel rods per assembly, 1 assembly per basket, and a maximum steel rod exposure of 32.5 GWd/MTU. Fuel assemblies with activated stainless steel rods must be cooled for either a minimum of 21 years or the loading table minimum cool time (as adjusted for additional cool times for nonfuel hardware and the presence of damaged fuel in the TSC, as applicable) plus 1 year, whichever is greater.

Fuel assemblies loaded with in-core instrument thimbles must meet the additional cool time requirements in Table 5 or Table 15, as appropriate, for BPRAs or GTPDs, whichever is bounding, for Westinghouse and B&W fuel types and for RCCs for CE fuel types. The additional cool time requirements for assemblies with nonfuel hardware are added to any additional cool time requirements due to damaged fuel also being loaded in the same TSC. RCCs are restricted to fuel storage locations 11, 12, 13, 18, 19, 20, 25, 26 and 27 in Figure 1.

One NSA is permitted to be loaded in a TSC in fuel storage locations 11, 12, 13, 18, 19, 20, 25, 26 or 27 in Figure1. NSAs may contain source rods attached to hardware similar in configuration to guide tube plug devices (thimble plugs) and burnable absorbers, in addition to containing burnable poison rodlets and/or thimble plug rodlets. NSAs, GTPDs, and BPRAs for CE fuel types are not allowed contents. In addition, the following unirradiated, nonfuel hardware may be loaded with the fuel assemblies: stainless steel rods inserted to displace guide tube dashpot water, instrument tube tie components, and guide tube anchors or similar devices. Axial power shaping rods are not allowed contents.

Under-burned Westinghouse 15x15 assemblies (assemblies with a maximum enrichment greater than that dictated by the burnup credit loading curve) may be loaded provided that an RCCA is inserted in the assembly, the enrichment is equal to or less than 4.05 wt. % 235U, and the assembly burnup is greater than or equal to 12,000 MWd/MTU. When loading under-burned fuel, the RCCAs must be full length Ag-In-Cd RCCAs comprised of stainless steel clad rods constructed with 80% Ag, 15% In and 5% Cd absorber pellets and having an exposure equal to or less than 200,000 MWd/MTU. The basket must include absorber sheets with an effective 10B areal density of 0.036 g/cm2. Any assemblies loaded without an RCCA inserted must meet the burnup credit loading curve for the applicable assembly loading profile. Burnup credit curves, and the criticality requirement for RCCA insertion, are only applicable to systems not crediting moderator exclusion. Initial enrichment up to 5 wt% 235U, with no burnup or RCCA requirement, is permitted when crediting moderator exclusion.

(iii) Undamaged BWR assemblies

Undamaged BWR fuel assemblies within the 87 BWR basket assembly shown in Figure

3. Undamaged fuel is spent nuclear fuel that does not have any visible deformation other than uniform bowing that occurs in the reactor, assemblies that do not have missing rods, and assemblies with missing rods that are replaced by solid stainless steel or zirconium filler rods that displace a volume equal to or greater than the original rods and assemblies that do not contain structural defects that adversely affect radiological and/or criticality safety and/or result in unsupported fuel rod lengths in excess of 60 inches and that can be handled by normal means. BWR/2-3 assemblies are to be loaded into short TSCs, and BWR/4-6 assemblies are to be loaded into long TSCs.

The fuel assemblies consist of uranium dioxide pellets with zirconium alloy-clad fuel rods and zirconium alloy-clad water rods or holes. Empty rod positions must be filled with solid, unirradiated, nonfuel filler rods that displace a volume equal to, or greater than, that of the fuel rod that the filler rod replaces. Prior to irradiation, the fuel assemblies must be within the dimensions and specifications of the hybrid assemblies listed in Table 19. In addition, the BWR fuel must meet the fuel class assembly specifications listed in Table 20. Fuel assembly burnup, minimum initial average enrichment10, and cool time requirements are provided in Table 23, Table 24, and Table 25.

Undamaged BWR fuel must meet the hybrid fuel assembly enrichment and the TSC neutron absorber sheet 10B density for loading up to the 87 and 82 assembly loading patterns for fuel with axial blankets in Table 21 and fuel without axial blankets in Table

22. Spacers may be used to axially position fuel assemblies to limit their axial movement in the TSC. Unenriched and unirradiated fuel is not authorized for loading, except that unenriched axial blankets are permitted, provided that the nominal length of the blanket is not greater than 6 inches.

For a TSC that is less than fully loaded, empty fuel storage locations shall begin with location 44, followed by locations 43, 45, 33, 55, 32, 56, 34, 54 and continuing outward, as required, in an approximately symmetric pattern as shown in Figure 3. Allowable fuel assembly locations for the 82 assembly BWR fuel assembly basket configuration are shown in Figure 4. Prior to use of the 82 assembly configuration, the center cell weldment and upper weldments of nonfuel locations must be physically blocked (fuel storage locations 44, 32, 34, 54, 56 shown as in Figure 4).

BWR fuel assemblies may be unchanneled, or channeled with zirconium-based alloy channels. BWR fuel assemblies with stainless steel channels are not authorized.

10 Assembly average fuel enrichment is the enrichment value determined by averaging the 235U wt% enrichment over the entire fuel region (UO2) of an individual assembly, including axial blankets, if present.

The 82-Assembly configuration is the result of criticality constraints on maximum enrichment. When crediting moderator exclusion, the 82-Assembly configuration is not required, as full capacity (87-Assembly) is permitted at an initial enrichment up to 5 wt%
