Container system for radioactive waste
First Claim
1. A radioactive waste container system comprising:
- a canister having an interior chamber for holding radioactive waste and an open top;
a lid assembly comprising a confinement lid and a shielded lifting lid, the confinement lid being detachably mounted to the shielded lifting lid;
the confinement lid being configured for mounting on the canister and having a first thickness;
the shielded lifting lid including a lifting attachment and having a second thickness;
wherein the confinement lid is independently mountable on the canister relative to the shielded lifting lid;
wherein the shielded lifting lid comprises a plurality of first bolt holes and the confinement lid comprises a plurality of second bolt holes, the first and second bolt holes concentrically aligned; and
a plurality of first mounting bolts inserted through some of the first bolt in the shielded lifting lid and attaching the confinement lid to the canister without engaging the shielded lifting lid.

Abstract
A container system, for radioactive waste and method for using the same is provided. The system includes a canister configured for holding radioactive waste and a lid system. In one embodiment, the lid system comprises a two-part lid assembly including a confinement lid and a shielded lifting lid. The confinement lid is detachably mounted to the confinement lid. In use, the lifting lid supports die confinement lid for lifting and placement on the canister. The lifting lid further shields operators while the confinement lid is mounted to the canister. Thereafter, the lifting lid is removed and may be reused for confinement lid mountings on other canisters. In one embodiment, the confinement lid is bolted to the canister. The canister may be disposed in a protective overpack for transport and storage.
