This report documents an Occupational Radiation Exposure (ORE) analysis that was performed for
the US International Thermonuclear Experimental Reactor (ITER) Dual Coolant Lead Lithium (DCLL)
Test Blanket Module (TBM). This analysis was performed with the QADMOD dose code for anticipated
maintenance activities for this TBM concept and its ancillary systems. The QADMOD code was used to
model the PbLi cooling loop of this TBM concept by specifying gamma ray source terms that simulated
radioactive material within the piping, valves, heat exchanger, permeator, pump, drain tank, and cold trap
of this cooling system. Estimates of the maintenance tasks that will have to be performed and the time
required to perform these tasks where developed based on either expert opinion or on industrial
maintenance experience for similar technologies. This report details the modeling activity and the
calculated doses for the maintenance activities envisioned for the US DCLL TBM.
Here’s what’s next.
