Internals Removal
|
All work was performed dry because of the condition of the reactor tank and the lack of water processing on the site. All the work on the internals was done remotely until dose levels allowed the final pieces to be removed hands on. Dose levels prohibited using standard long handle tools from a platform. Instead, operators were positioned 20-feet (6-meters) above the work and 6-feet (2-meters) from the edge. Although a shield was used it's ALARA benefit was to keep the operators outside of the gamma "plume" that was exiting the vessel opening.
