Nuclear & SMR
Gain a better understanding into the dynamic behaviour of nuclear cycles through Flownex® Simulation Environment. Flownex® has proved itself to save time and money in the design and commissioning of Nuclear systems with integrated Heat & Flow simulation together with control simulation.
OVERVIEW
Flownex® SE enables system level modeling of nuclear plant fluid mechanics, heat transfer and neutronic response in both transient and steady state.
APPLICATIONS
TOTAL PLANT MODELLING
Leading nuclear companies use Flownex® SE for complete nuclear plant modeling. The reactor, balance of plant and control logic are all integrated into one versatile model, focusing on system level performance and solutions. It includes:
- Integrated reactor response using point kinetic neutronics
- Balance of plant performance management using state of the art flow and heat transfer
- Control system configuration and testing using industry standard and analog control logic capability
LICENSABLE TECHNOLOGY
Nuclear technology is built on licensing. The Flownex® nuclear version can be issued with a Certificate of Compliance and a Verification & Validation pack is available for purchase, leading the way towards your design approval.
SMR DESIGN
Flownex® SE advances SMR plant design from concept to detail design phases. Its fast solving
speed and accurate representation of expected performance allows quick and informed decision making. This drives SMR projects beyond research towards successful implementation by performing:
- Technical feasibility studies
- Parametric and optimisation studies
- Component performance assessments
- Plant response simulations
- Accident scenario investigations
- Qualification of promising designs for primary, auxiliary and safety systems
