Carbon value: Lifetime extensions of nuclear reactors could save billions in climate mitigation costs
On the road to achieving net-zero by midcentury, low- or no-carbon energy sources that slash carbon dioxide emissions are critical weapons. Nevertheless, the role of nuclear energy—the single largest source of carbon-free electricity—remains uncertain.
Nuclear energy, which provides 20 percent of the electricity in the United States, has been a constant, reliable, carbon-free source for nearly 50 years. But our fleet of nuclear reactors is aging, with more than half of the 92 operating reactors across 29 states at or over 40 years old—the length of the original operating licenses issued to the power plants. While some reactors have been retired prematurely, there are two options for those that remain: retire them or renew their license.

The Kraken framework is a computational reactor analysis framework developed at VTT for both safety analyses and general research and educational purposes. With the neutronics side building heavily on the in-house Monte Carlo code Serpent, the framework couples novel Finnish solvers for core physics but also couples to state-of-the-art third pary solvers. The Python based multi-physics driver Cerberus and the Python package of pre- and post-processing methods KrakenTools aim to simplify core analysis tasks. Work is ongoing to license the framework free of charge for non-commercial use with distribution through the OECD/NEA data bank and the RSICC.
Agenda:
1. Motivation behind Kraken development.
2. Current solvers in the Kraken framework.
3. KrakenTools, a Python package to help working with Kraken solvers.
4. Coupled multi-physics calculations with Kraken.
5. Demonstration: SMR operating cycle analysis with Kraken.
6. Current status of licensing and distribution.
