THE BENEFITS OF A DIGITAL TWIN IN SUPPORT OF COMPLEX LONG-TERM OPERATIONS

抄録

The LongOps programme (2019-2024) unites three end users with similar multi-decadal challenges: TEPCO has the challenge of decommissioning the Fukushima Daiichi reactors and especially reaching into the reactor pressure containment vessels to retrieve fuel debris; the UK Nuclear Decommissioning Authority has a complex multi-building decommissioning liability estimated to be £178B over more than 100 years; and, the UK Atomic Energy Authority started in 2024 to conduct first of a kind decommissioning of the JET fusion reactor at Culham aiming to complete by 2040 using long reach booms to access the reactor pressure vessel.
