Pedigree
Altran Praxis has a long track record of developing
software and
systems to the highest levels of integrity against a range of international and national
safety standards including IEC 61508 and industry standards such as the IEC and ISC variants.
Throughout this time, complementing its critical and embedded software development, Praxis has also delivered a broad range of safety engineering services. These include safety case development and Independent Nuclear Safety Assessment (INSA).
Focus
As the dependency on programmable systems and smart instruments grows, we are assisting organisations with the safe integration of the latest software intensive technology.
We also continue to provide safety audits and assessments to meet all relevant international safety standards.
Praxis is advising nuclear industry clients on advanced software engineering methods and is demonstrating software development that achieves high safety integrity levels, exploiting extensive safety-critical system development experience from other markets.
We fully appreciate that legacy systems have a key part to play in the future of the nuclear industry and we are advising on strategy and supporting such systems.
Example Nuclear projects
-
Altran Praxis awarded further work on UK Nuclear New Build programme.
- Praxis has recently completed an assignment at Dungeness B power station preparing Engineering Change reports which gain approval for safety modifications of the Statutory Outage for Reactor 21 (the three yearly reactor shutdown to allow maintenance, inspection and repair). Modifications covered the following systems: main cooling pipework, reactor vessel cooling pipework, turbine condenser cooling supply, reactor gas circulator pump lifting frame and nitrogen shutdown.
- Praxis is supporting CINIF with a study of techniques for high-integrity software development and assessment. This includes analysis of the effectiveness of specific assurance techniques in identifying software faults and in supporting Safety Integrity Level (SIL) claims for software.
- Praxis has been engaged by a government agency to investigate the hardware and software techniques required for an ultra high-integrity micro-processor unit related to nuclear applications. Working closely with Cambridge Consultants, a sister company within Altran, the project team have been able to prove required principles and demonstrate a working system.
- Praxis has undertaken software verification and validation services on safety-related plant control applications. Activities included design review, software verification (including formal proof), concurrency analysis and object-code verification.
- Praxis provides consultancy to numerous nuclear sites, including provision of review services for Sellafield Ltd against IEC 61508 and guidance on the safety issues associated with concurrent systems for Scottish Nuclear.
- Praxis is developing safety management systems and system development guidance for a Control and Instrumentation (C&I) manufacturer to enable compliance with IEC 61508.
