OPTIMUS-L Package SAR December 2023 Docket No. 71-9390 Revision 23D NAC International 1.2-10 Maximum Quantity of TRU Waste Contents per Package:

1. Greater than Type A quantities of radioactive material in the form of solids or dewatered materials in secondary containers.

2. Greater than Type A quantities of radioactive material in the form of activated reactor components or segments of components of waste from a nuclear process or power plant.

3. That quantity of any radioactive material not generating spontaneously more than 100 thermal watts of radioactive decay heat.

4. TRU waste not exceeding the fissile gram equivalents (FGE) of fissile radioactive material in Table 1.2-1 for the specified criticality configuration limits.

5. TRU waste contents shall comply with regulatory dose rates, as demonstrated in accordance with Chapter 7, Attachment 7.5-1. Note: Maximum activity limits for key individual gamma-emitting contents (e.g., Co-60 and Cs-137 including Ba-137m daughter product) and neutron-emitting contents (e.g., Cf-252 and Cm-244) are provided in Table 1.2-3 Loading Restrictions:

1. TRU waste contents shall be in secondary containers (e.g., drums or boxes).

2. TRU waste contents with a total decay heat exceeding 50 watts shall be inerted with helium gas.

3. Explosives, corrosives, non-radioactive pyrophorics, and sealed items containing compressed and/or flammable gas (e.g., aerosol cans, lecture bottles, etc.) are prohibited.

Pyrophoric radionuclides may be present only in residual amounts less than 1 wt%. All nonradioactive pyrophoric material be reacted (or oxidized) and/or otherwise rendered nonreactive prior to placement in a secondary container (e.g., drum).

4. Free liquids shall not exceed 1% of the CCV cavity volume.

5. Maximum weight of the CCV contents, including TRU waste, secondary containers, and internal structures (e.g., CCV bottom support plate, SIA, etc.) and dunnage or shoring shall not exceed 3,500 pounds (1,587 kg).

1.2.2.2 Irradiated Fuel Waste The materials in Irradiated Fuel Waste (IFW) are restricted to low enriched uranium (LEU) fuel and metal structural components (e.g., cladding, liners, baskets, etc.) meeting the following requirements and restrictions.

(1) Maximum activity limits are provided for entire content in a package. The corresponding maximum resultant dose rates from these isotopes at the listed activity limits are shown for the bare case (i.e., package without an SIA) in Table 5.1-2. Compliance with external dose rate limits shall be demonstrated with the isotope inventory of the individual package contents using the dose rate per curie values listed in Tables 7.5-1 and 7.5-2, as outlined in.5.1.

(2) Package configuration without an SIA inside the CCV cavity.

(3) Package configured with the 1-inch SIA inside the CCV cavity.

(4) Package configured with the 21/4-inch SIA inside the CCV cavity.

(5) Includes Ba-137m daughter.

OPTIMUS-L Package SAR December 2023 Docket No. 71-9390 Revision 23D NAC International 5.1-2 and cab (occupied position) dose rates are only calculated from the side of the package, as the package is only transported in the upright position.

For TRU waste, the contents of the package are variable, and the final isotope inventory is different for each TRU waste drum or irradiated fuel waste liner, the maximum dose rates are strongly dependent on the specific contents. As an example, maximum dose rates are calculated for the maximum allowable quantity of four individual isotopes. The isotopes considered are Co-60, Cs-137, Cf-252, and Cm-244. Examples of the maximum activity in a package of the conveyance that would result in the limiting dose rate at 90% of the regulatory limit are provided in Table 5.1-2, along with the resulting total dose rates at each location. It should be noted from this table that, due to the relatively thin layers of shielding provided by the packaging, the maximum isotopic activities permissible in the contents are very limited. The primary content intended for transport in the package is drums of TRU waste with relatively low activity. Thus, the relative hazard of the contents is limited.

For TRISO compact contents, the payload is composed of fresh, unirradiated fuel, therefore dose rates on package surfaces will be negligible. Based on the significant shielding presented by the package design and that the payload is unirradiated material fresh fuel, no shielding evaluations are required.

2. For a maximum load, there must be a distance to the drivers cab of at least 20 ft from the centerline of the package.

3. Includes Ba-137m daughter.

OPTIMUS-L Package SAR December 2023 Docket No. 71-9390 Revision 23D NAC International 5.5-12 5.5.3 Example Cases This section provides sample calculations of demonstrating compliance for a hypothetical group of packages with bare casks that are not secured to the center of the trailer (i.e. using the Dose Rate/Ci values from Table 7.5-1). The same example calculations can be applied to a centered package, with or without SIAs, using the Dose Rate/Ci values in Table 7.5-2.

To provide an example of the demonstration of compliance for a group of 10 hypothetical packages, dose rates are calculated for 10 sample isotope inventories (labeled Content ID 1 - 10) in Table 5.5-9 using the Dose Rates/Ci values from Table 7.5-1. The results in this table show that the calculated dose rates for the package surface, 2-meter, and HAC 1-meter are far below the limit, indicating that all packages are acceptable for transport from this hypothetical group of packages. Note that the trailer surface dose rate is not calculated because it is always bounded by the package surface location (i.e. the package surface dose rate limit will always be reached before the trailer surface).
