Savannah River Laboratory dose-to-man model. Appendix A. Deterministic studies - SRL Model

Solid waste contaminated with radionuclides has been buried at the Savannah River Plant (SRP) burial ground since 1953. The radionuclides include alpha-emitting transuranium (TRU) nuclides, beta- and gamma-emitting activation and fission products, and tritium. To evaluate current operating limits for burial of this waste and to aid planning for the eventual decommissioning of the burial ground, the long-term dose to man from each type of waste must be estimated. The dose projections will provide guidance in choosing alternatives for a burial ground decommissioning plan. Such alternatives may include exhuming selected segments of the waste to reduce the long-lived radionuclide inventory or providing additional backfill over the waste trenches. The sensitivity of dose projections to the length of institutional control over the burial ground will provide an estimate of the minimum time period such control must be maintained
