Nuclear thermal-hydraulic analyses
We ensure the safety of your facility. Reliably and independently, using qualified computer codes.
Areas of expertise
The team of dedicated experts has implemented the nuclear thermal-hydraulic codes in a wide range of reactors. These include:
- Pressurized water reactors (PWR)
- Boiling water reactors (BWR)
- High temperature reactors (HTR)
- Liquid metal fast reactor (LMFR)
- Molten salt reactor (MSR)
- Research reactors
- Chemical reactors
For these reactor types, we work on the international standard problems (ISP), research projects, code-to-code benchmarks and more. Our in-house developed SPECTRA code is highly versatile and can handle many reactor types and configurations. Contact us for more information.
What codes do we use?
Do you want to build a new reactor? Or do you want to modify your existing reactor? We use independent software packages to help you perform nuclear thermal-hydraulic design analyses and safety studies. Our team is ready to assist you to continue operation. The codes we use are:
- MELCOR, the US NRC severe accident code for modelling the progression of accidents within light water reactors.
- RELAP5, the US NRC thermal-hydraulic code to perform best-estimate transient simulations of the coolant system and core for design basis accidents.
- TRACE/PARCS, the US NRC thermal-hydraulic code to analyse large and small break LOCAs and system transients in PWRs and BWRs.
- SPECTRA, the NRG thermal-hydraulic code. This code is used in various kinds of reactors and can be used to analyse thermal accident scenarios, such as loss-of-coolant accidents, operational transients and other accident scenarios in nuclear facilities.
