A Study on optimization of dismantling scenarios in Fugen decommissioning project, 3

Koda, Yuya ; Tezuka, Masashi  ; Yanagihara, Satoshi*

In order that we implement the decommissioning safe and reasonable, which is important to select the optimal scenario assuming multiple scenarios in advance in the discussion stage of the dismantling work. We assume a realistic simple dismantling scenario to target the turbine equipment and reactor coolant purification system equipment, it has been studied technique to select the optimal dismantling scenario as the PMD evaluation item of Work artificial number, worker exposure dose, etc. In this presentation, we report the results of a study for the heavy water, helium-based equipment.
