Process Modelling

Platom’s Process Modelling and Analysis team both produces process models, simulations and analysis data, and is able to assess, interpret and summarize existing analysis data provided by a third party (e.g. for safety analyses). We can conduct the entire analysis work from start to finish, or handle smaller parts of the larger process. With the help of our high quality network of partners, we are able to find the suitable expertise even for the most uncommon analysis challenges.

Our analysis experts can support our customers e.g. with the following:

• Deterministic safety analyses for nuclear facilities
• Process analysis related to system modernization or modification
• Virtual model construction on plant or system level
• I&C system modelling
• Optimization studies
• Analysis of the effects of altered requirements e.g. for safety systems
• Engineering studies to support equipment or system deliveries
• Probabilistic risk and safety analyses (PRA / PSA)
• Neutronics analyses and activation calculations

Platom has extensive experience in thermal hydraulic process analysis and simulation. We use the versatile APROS-software, which we can use to also carry out I&C and control integration to our process models, and which is able to conduct dynamic modelling. We utilize our know-how of different nuclear reactor types and our expert’s problem solving mindset to produce the best possible results.

Process modelling is part of high quality, safety first-design work, ensuring safety and functionality, proving requirement compliance, and optimizing costs. With the help of process modelling, it is possible to assess process functionality and efficiency and study optimization options. Additionally, process modelling can be used to study different options for plant modifications and modernizations, to identify the best option from a safety and cost-efficiency viewpoint. First of all, process modelling is a form of quality assurance, with a focus on safety, cost-efficiency, and requirement compliance.

”Well designed is half made”, and once it’s been modelled, it’s very well designed. By producing a model, simulating, and analysing the results, it’s possible to ensure that the chosen design is going to work smoothly and does not contain any hidden problems. When a plant modification or modernization can be implemented without design-related issues on the first attempt, there are clear savings both in time and money.

An integral part of the service is also the assessment of analyses carried out by other parties. For example, we can produce a clear, understandable and requirement compliant analysis summary for a new nuclear power plant’s preliminary safety analysis report’s transient and accident analysis section (PSAR chapter 15), which is based on extensive amounts of detailed analysis data.
