Studsvik Scandpower and VTT partner to develop Serpent software

6 July 2022

Sweden’s Studsvik Scandpower and VTT Technical Research Centre of Finland have initiated a strategic partnership to address the growing need for Quality Assured neutronic simulation in the Advanced Reactor market, according to Studsvik. Studsvik is a global leader in neutronic simulation software while VTT leads development of advanced software for nuclear reactor and power plant modelling such as the Serpent Monte Carlo code.

The partnership aims to expand the commercial uses of Serpent software to the advanced civil nuclear community around the globe and will continue the growth of the Studsvik product line with a new version of Serpent under Studsvik's NQA-1 and 10 CFR50 Appendix B Quality Assurance program, Serpent-SSP.

In recognition of the regulatory challenges for advanced reactor designers today, Studsvik aims to provide the quality assurance, software support and engineering feature development in Serpent to enhance advanced reactor designer's regulatory submittals with confidence and enable VTT to provide their expert consultation in the global advanced reactor industry.

Studsvik and VTT will work together to develop new methodology for the modelling of advanced reactors through this partnership, which will provide ease of access to the VTT organisation and expertise for Studsvik customers. Studsvik and VTT aim to expand applications and support of Serpent into new fields including medical physics, radiation shielding, and other neutron and radiation transport applications.

Serpent is a multi-purpose three-dimensional continuous-energy neutron and photon transport code, developed at VTT since 2004. The continuous-energy Monte Carlo method can be used for a wide range of particle transport applications. The physics model in Serpent covers neutron, photon and coupled neutron-photon simulations. Serpent has more than 1,000 users in 250 organisations around the world.
