National Nuclear Laboratory (NNL) and Studsvik Scandpower (Studsvik) have concluded agency and licence agreements which appoint Studsvik Scandpower as agent for the sale and distribution of NNL’s ENIGMA fuel performance software.
Studsvik will market the software alongside its own fuel core analysis software, CMS. This is great news for customers who will benefit from this unique combination of tools and service.
The ENIGMA code is a state of the art fuel performance code which has been extensively validated and offers customers a comprehensive modelling capability across a range of fuel types.
NNL has been a long time user of SSP’s CASMO code and this agreement will further strengthen the relationship between the two organisations.
Commenting on the agreement Dr Paul Howarth, NNL’s Managing Director said:
“This is an example of NNL expertise in the area of fuel performance being linked with Studsvik’s core analysis software. We believe this will offer customers a comprehensive package and provide a combination of tools unique in the marketplace. The opportunity to work with Studsvik is one that we look forward to building and strengthening over the years.”
Dr Thomas Smed, President of Studsvik Scandpower stated;
“This is an effort by Studsvik and NNL to join forces and combine two established technologies into a multiphysics application that we believe will be valuable for our customers. It provides a basis for a better understanding of how our customers can protect their fuel in Nuclear Power Plant operation.”
ENIGMA is a state of the art fuel performance code that calculates the thermo-mechanical performance of an LWR fuel rod in both steady-state and transient conditions. ENIGMA is used in the design, licensing and safety analysis performance of a range of fuel types, including UO2 and MOX and offers customers a comprehensive modelling capability across a range of fuel types, backed up by extensive validation. The code has been used for several definitive design and licensing assessments for both UO2 and MOX fuel, including licensing UO2 and gadolinia-doped UO2 in Sizewell ‘B’ and the Finnish Loviisa VVER-440 reactor, and mixed oxide (MOX) fuel in the Swiss Beznau-1 PWR. ENIGMA is also used in support of MOX production in the Sellafield MOX Plant (SMP) and to perform feasibility studies for advanced fuels, as well as for strategic assessments such as plutonium management in new build UK reactors
