Quintessa’s Continuing Support to SSM’s Review of SKB’s Safety Assessment SR-PSU

In November 2017, the Swedish Radiation Safety Authority (SSM) published a series of reports associated with the main phase of the review of SKB’s assessment (SR-PSU) of the long-term safety for the expansion of the final repository for low and intermediate level waste at Forsmark (SFR).

SSM has contracted a number of external experts to support its review of SR-PSU. Quintessa is supporting SSM in the areas of geochemical review, reactive transport modelling, radionuclide transport modelling and biosphere modelling.

Within the main review phase, Quintessa was tasked with re-implementing key aspects of SKB’s radionuclide transport and biosphere models using the AMBER code and with developing independent models of the evolution of engineered barrier materials using the QPAC code. Quintessa has authored the following chapters in the main phase review reports:

The initial review phase findings were published in SSM report 2016:09.
