EPRI-ESCP Thermal Modelling Benchmark

As part of an international benchmark of the Electric Power Research Institute, BGZ – together with GNS and WTI – compares thermal calculation methods on an instrumented TN^®32 cask that was loaded at the North Anna nuclear power plant (USA) in 2017.

The aim is to estimate cladding tube temperatures more realistically and to quantify the sensitivity of different modelling approaches. The first modelling phase has been completed and published. Phase 2 deepens the uncertainty and sensitivity analyses of the various modelling approaches and feeds into the best-estimate proofs for future storage licences. A detailed final report had not yet been published at the time of going to press.
