The INTOR reference design was developed to permit limited maintenance operations external to the reactor in a “hands-on” mode; all internal operations would be remotely accomplished. The design embodies those requirements for shielding, tritium containment and cleanup, and confinement of contaminated particulate matter to permit personnel access. The cost reflects these requirements, at least to first order. The impact of personnel access on the reactor design and its cost are cause to reexamine the maintenance approach on which much of the present configuration is based. The purpose of this study is to compare the benefits and costs associated with personnel access maintenence procedures to those associated with all-remote maintenance procedures and to identify modifications to the baseline design that could enhance maintenance operations.
