a. A complete description and analysis of the representative bounding accidents are presented in Appendix F.
b. Increased risk of fatal cancers per year is calculated by multiplying the [consequence (dose) x latent cancer conversion factor] x annual frequency. For dose consequences and latent cancer fatalities per dose, see tables in Appendix F.
c. The waste type for which the accident scenario is identified as a representative bounding accident. A representative bounding accident may be identified for more than one waste type. These waste types are high-level, low-level, mixed, and transuranic.
d. Replacement High-Level Waste Evaporator.
e. The frequency of this accident scenario is within the anticipated accident range.
f. The frequency of this accident scenario is within the unlikely accident range.
g. The frequency of this accident scenario is within the extremely unlikely accident range.
h. F/H-Area Effluent Treatment Facility.
i. The frequency of this accident scenario is within the beyond-extremely-unlikely accident range.
j. Intermediate-Level Nontritium Vault.
k. Savannah River Technology Center.
l. F3 tornadoes have rotational wind speeds of 254 to 331 kilometers (158 to 206 miles) per hour.
m. Transuranic.
