Evaluation of dose rate and uncertainty of fuel debris in a canister for the safe retrieval of damaged nuclear fuel [PDF]

open access: yes, 2021
Damaged fuel from core melting accidents like Three Mile Island and Fukushima Daiichi need to be retrieved and disposed. Retrieval of damaged fuel is considerably more complex than for standard fuel as fuel is relocated and deformed during the accident ...

Development of Numerical Simulation Method to Evaluate Heat Transfer Performance of Air Around Fuel Debris: Part 2 — Validation of JUPITER for Free Convection Heat Transfer [PDF]

open access: yes, 2017
A dry method is one of fuel debris retrieval methods for decommissioning of TEPCO’s Fukushima Daiichi nuclear power station. If stopping the water leakage from a damaged primary containment vessel (PCV) is impossible, the dry method may be adopted ...

Development of Numerical Simulation Method to Evaluate Heat Transfer Performance of Air Around Fuel Debris: Part 1 — Effect of the Debris Shape [PDF]

open access: yes, 2017
Fuel debris retrieval in atmospheric conditions is proposed as one candidate in the Fukushima Daiichi NPS since it can suppress generation of the contaminated water. However, there are unknowns and uncertainties to evaluate the air cooling performance of
