1. A method of filling and sealing a container with radioactive debris, comprising the steps of: placing a container within a support structure submerged in water and covering the support structure and container with a hood submerged in the water; and, while the hood remains submerged in water, then:  lowering a connector portion of a fill line into a secondary volume of the container and connecting the connector portion of the fill line to a fill tube of the container;  lowering a connector portion of a dewatering line into the secondary volume of the container and connecting the connector portion of the dewatering line to a dewatering tube of the container;  injecting a slurry of radioactive debris into a primary volume of the container through the fill line and fill tube; and  removing fluid from a slurry of radioactive debris within the container through the dewatering tube and dewatering line. 2. The method of  claim 1 , further comprising the steps of: claim 1 isolating the fill line and fill tube using a first pair of valve assemblies;  isolating the dewatering line and dewatering tube using a second pair of valve assemblies; and  raising the respective connector portions of the fill line and dewatering line out of the secondary volume of the container. 3. A The method of  claim 2 , further comprising the steps of: claim 2 moving the hood relative to the support structure and container into an intermediate position;  introducing a gas into the hood to displace a water within the hood to a level below an upper end of the container;  lowering a straw into the secondary volume of the container and removing water from the secondary volume through the straw; and  raising the straw out of the secondary volume. 4. The method of  claim 3 , further comprising the steps of: claim 3 injecting a dye into the secondary volume after the water within the hood is displaced to a level below the upper end of the container; and  visually checking a water level in the secondary volume using a camera. 5. The method of  claim 2 , further comprising the steps of: claim 2 moving the hood relative to the support structure and container into a sealing position;  lowering a cover into sealing engagement with the container; and  securing the cover to the container. 6. The method of  claim 1 , further comprising the step of vibrating the container to facilitate removal of water from the slurry of radioactive debris. claim 1 7. The method of  claim 1 , further comprising the step of monitoring an amount of radioactive debris within the container using a scale positioned between the support structure and the container. claim 1
