The use of software based equipment and systems in nuclear power plants has been growing in recent years, both as a result of the need to replace obsolete analog equipment and as a means of improving and ensuring satisfactory levels of plant availability and safety.

Software can now be found in safety applications (e.g. Nuclear power plants – Instrumentation and control systems important to safety – Software aspects for computer-based systems performing category A functions Scope and object This International Standard provides requirements for the software of computer-based I&C systems of nuclear power plants performing functions of safety category A as defined by IEC.

With the evolution of computer hardware and software, the analog human-machine systems of the main control room in the nuclear power plant have been replaced with digital systems.

Computer-based systems are increasingly being used to implement safety functions as part of Instrumentation and Control (I&C) systems in Nuclear Power Plants (NPPs). Any breach of security in these NS-G is applicable to NPP I&C systems important to safety; and NS-G is applicable to software used in such systems.

All of these systems are maintained and inspected regularly, and upgraded when necessary, to ensure plants meet or exceed strict safety standards established by the Canadian Nuclear Safety Commission.

Protection Systems for Nuclear Power Generating Stations,” (Ref. 2) or IEEE Std.“Criteria for Safety Systems for Nuclear Power Generating Stations,” and the correction sheet dated Janu (Ref. For nuclear power plants with construction permits. This first report on Safety Classification for I&C in Nuclear Power Plants describes the current status in classification of I&C systems, identifies key causes for difficulties as well as potential solutions.

It is important to note that safety classification of systems and components is a multidisciplinary issue. Nuclear power plants - Instrumentation and control systems important to safety - Software aspects for computer-based systems performing category B.

I'll answer for France mostly. Physics simulation codes We code mostly in Fortran, though the new codes are written in C/Python.

That's for the "physics" codes, i.e. neutron transport/diffusion, thermal codes, etc. Python really is becoming more. Nuclear power plants.

IEC provides requirements and recommendations for the instrumentation and control for systems important to safety of nuclear power plants. It indicates the general requirements for systems that contain conventional hardwired equipment, computer-based equipment or a combination of both types of equipment.

The U.S. Nuclear Regulatory Commission (NRC) is issuing a revised regulatory guide (RG), Revision 1 of RG``Test Documentation for Digital Computer Software Used in Safety Systems of Nuclear Power Plants.'' This RG endorses the Institute of Electrical and Electronic Engineers (IEEE).

Generally, I would say Linux or other Unix-based systems would be the most ideal for nuclear plants. Linux systems have more versatility than Windows for these kinds of applications, especially since the system’s kernel (the layer between the hard. adequacy in safety-critical software.

understand the relationship between the software reliability and number of faults remaining in the software. Managing the aging of digital control systems ensures that nuclear power plant systems are in adequate safety margins during their life cycles.

Software is a core component in the execution of control logic and differs between digital and analog control systems. The hardware aging management for the digital control system is similar to that for the analog system, which has matured over decades.
