Instrumentation and controls architectures in new NPPs
Instrumentation and control systems are the nervous system of a nuclear power plant. They monitor all aspects of the plant's health and help respond with the care and adjustments needed. Progress in electronics and information technology has created incentives to replace traditional analogue instrumentation and control 'I&C' systems in nuclear power plants with digital I&C systems. Digital I&C ...

Regulatory independence and accountability: a survey of international nuclear regulatory regimes
As the government of India considers development of an independent regulator for civil nuclear power, examples from other nations around the world, including those with established civil nuclear programmes and those now developing new nuclear, provide interesting insights and lessons to be learned. This paper compares the organisational structure of the Indian governmental agency, the Nuclear ...

An applied research study on information technology talent management and knowledge management innovations for Generation Y information technology professionals in the nuclear power industry
Nuclear power plants rely on computerised Instrumentation and Control (I&C) systems in monitoring, control and protection at nuclear facilities. I&C systems serve a critical role in monitoring and control functions in nuclear power plants (National Research Council, 1997). To support the use of I&C systems, nuclear power organisations have expanded the intellectual capital of their workforces ...

Regulations and standards for the measurement of performance and management of ageing of I&C systems of nuclear power plants
Instrumentation and Control (I&C) equipment is vital to the safety and viability of nuclear power plants. This equipment must provide accurate and timely measurements of plant control and safety systems to ensure efficient operation and guard against mishaps. Given this, numerous regulations, standards and guidelines have been devised to formulate requirements and establish maintenance methods to ...

Scalable diversity-oriented decisions and technologies for dependable SoPC-based safety-critical computer systems and infrastructures
An approach to development and implementation of multi-version technologies (MVT) for creating dependable system-on-programmable chip (SoPC)-based systems and infrastructures is described. It is based on a set of scalable diversity-oriented decisions selected using the proposed MVT-graph. This technique is applied for development of nuclear power plants (NPP) instrumentation and control (I&C) ...

The state of the art in nuclear power plant instrumentation and control
Advances over the past decade in process Instrumentation and Control (I&C) for nuclear power plants have occurred in three areas: 1. digital I&C; 2. sensors and transmitters; 3. online monitoring. These areas are the subject of this paper, including a discussion of the related opportunities and challenges.Keywords: digital instrumentation, digital control, nuclear power plants, NPP, nuclear ...

Nuclear power plant on-line sensor calibration monitoring implementation issues
The use of empirical models for on-line monitoring (OLM) of safety-critical instrumentation for calibration reduction has been investigated for over a decade. To help support the regulatory review of possible licence amendments for US nuclear power plants, a series of three NUREG/CRs is being developed for the US Nuclear Regulatory Commission. The third of these volumes, entitled 'Limiting Case ...

On system validity, quasi-experiments, and safety: a critique of NUREG/CR-6393
Based on the methods of Cook and Campbell (1979), a quasi-experimental validation model for complex human–machine systems has been recommended for the final evaluation of nuclear power plant control rooms (O'Hara et al., 1997). This model-based approach to validating systems and assuring safety is critiqued in terms of experimental theory and engineering practice. It is concluded that the model ...
