Rome, Italy

 

Introduction

A 5 day training module covering the design, conduct, reporting and follow up of inspection programmes for reactor electrical systems and instrumentation and control systems. It addresses activities undertaken by the regulatory authority to assure compliance with safety requirements during design, manufacture/fabrication, construction, installation and testing, commissioning and operation phases of the nuclear power plant lifetime. It includes design, conduct, reporting and follow up of regulatory inspection programmes during these phases. The module is made up of presentations, exercises and key issue discussion sessions and is presented by internationally recognised experts from European nuclear regulatory authorities and international organisation.

 

The training is intended for professionals involved in regulatory processes related to the design, construction, commissioning and operations of nuclear power plants and research reactors. Firstly, it is intended to create an understanding of compliance assurance activities undertaken by the regulatory authority, second the importance to safety of reactor electrical systems and instrumentation and control systems and their consideration in the safety assessment process and third the design, conduct, reporting and follow up inspection processes.  It covers the design, construction, commissioning and operational phases and the regulatory interaction, inspection and follow-up during these phases of project development.

Participants will require a basic knowledge of nuclear installation technology, nuclear and radiation safety and nuclear regulatory processes. 

 

Educational objective

The objective of this training module is to provide trainees with an understanding of regulatory compliance assurance activities and their application to reactor electrical systems and instrumentation and control systems during design, manufacture, construction, installation, commissioning and operation. The training will address the design, conduct and follow up of inspection programmes for these activities giving trainees an understanding of how regulatory processes work in practise.

A.4 Regulatory documentation - Peter Hughes

Key words nuclear safety, instrumentation and control systems, electrical power systems nuclear power plants research reactors, regulatory documentation

Synopsis

Licensees are required to document safety assessments of nuclear installations, derive operating technical specifications and establish surveillance and testing, in-service inspection, maintenance, radiation protection and other programmes. Operating procedures must also be developed to comply with operation technical specifications and to implement the control programmes. All these documents are subject to review and various levels of approval by the regulatory authority. An overview will be presented of the required documentation.

 

A.5 I&C principles for nuclear facilities and current challenges - Mauro Cappelli

Key words nuclear safety, principles for instrumentation and control systems, nuclear power plants research reactors

Synopsis

The lecture gives a general overview of instrumentation and control topics for nuclear applications. Why a plant must be monitored? Why a plant must be controlled? The answer to these questions gives rise to the introduction of sensors and physical actuators, and to the concept of control and closed loop control systems.  The lecture provides a comprehensive, yet introductory description of many aspects of modern nuclear instrumentation and control. A particular focus will be on the significance of I & C systems for safety and the challenges posed by I & C technology. I & C systems will be described in terms of their physical, functional and lifecycle features. A brief overview will be presented of all I & C product phases (design, qualification, supply chain commissioning, training, operations and maintenance, modernization). Finally, the lecture outlines the potential challenges to be faced when a new technology must be introduced (safety, security and licensing driven issues).  

 

Day 2 – Importance to safety of electrical systems and I & C systems

 

B.1 Safety requirements for electrical power systems for NPPs and research reactors - Peter Hughes

Key words nuclear safety, electrical power systems, nuclear power plants, research reactors, safety requirements Regulatory inspection processes for I & C systems

Synopsis

This presentation will describe the electrical systems at NPPs (and research reactors). The safety requirements that are applicable to electrical power systems will be identified and discussed.  The application of the graded approach to safety requirements for research reactors will be covered. The role of codes and standards, the design considerations that arise for nuclear safety and the design considerations that arise for electrical design will also be covered. The safety requirements for the design bases for the electrical power systems will be introduced and the considerations that the regulator needs to give to developing a suitable inspection plan.

 

 

B.2 Analogue I&C Systems - Mauro Cappelli

Key words nuclear safety, analogue instrumentation and control systems, nuclear power plants research reactors

Synopsis

The objective of the lecture is to provide a basic review of electronic design techniques and to learn how to treat sensors, actuators and analogue signals. This is a fundamental step for addressing the more advanced issues. The basic building blocks for electronic circuits:  active and passive components, signal conditioning, power control, cabling, basics of electromagnetic compatibility. The presentation covers how to design electronic circuits manually using mental calculations, and how to design and simulate electronic circuits using software tools and potential accident scenarios. Signal processing for analogue sensors is addressed together with power amplifier for physical actuators.  The analogue computer is discussed covering PID regulators. Limits for analogue I&C are covering: dynamic, signal to noise ratio and bandwidth.

 

B.3 Digital I&C Systems - Mauro Cappelli

Key words nuclear safety, digital instrumentation and control systems, nuclear power plants research reactors

Synopsis

The objective of the lecture is to develop a positively critical view of digital technology addressing why digital is substituting analogue I&C. An overview of analogue and digital sensors and actuators is provided and analogue to digital and digital to analogue conversion techniques are discussed.  A/D and D/A converters as control systems building blocks are addressed together with digital signal processing basic building blocks. The digital computer as a closed loop controller is discussed and real time computer concepts explained. Well known and typical catastrophic design errors for digital I&C systems are covered.

 

B.4 Identification and classification of SSCs and safety assessment - Phil Metcalf

Key words nuclear safety, nuclear power plants, research reactors, structures systems and components important to safety, safety classification

Synopsis

Different structures, systems and components play different roles in providing nuclear safety. These roles are of varying levels of importance and as such there is considerable value in classifying such structures systems and components with a view to identifying the importance of their safety role and thus the degree of effort that should be expended in assuring their assigned safety functions will be fulfilled. Amongst other aspects the classification scheme determines the degree of inspection and assurance that should be applied to the different safety classes. The presentation discusses the approach to classification of structures systems and components.

 

 

B.5 Classification of I & C and electrical power systems - Peter Hughes

Key words nuclear safety, instrumentation and control systems, electrical power systems nuclear power plants, research reactors, safety classification

Synopsis

Electrical power and I & C systems and component falling under the classification of those SSCs important to safety require particular consideration within the SSC classification scheme. Such classification for I&C systems depends on the role played by the system and this presentation will discuss the various roles played by I & C systems and how these are dealt with by the classification methodology.

 

 

Day 3 – Regulatory inspection processes for electrical systems

 

C.1 Design guidelines for electrical power systems - Peter Hughes

Key words nuclear safety, electrical power systems, design guidelines, nuclear power plants, research reactors

Synopsis

 

This presentation will discuss the implementation of the electrical power systems design basis which have been covered earlier in lecture B1.  The design of the electrical power systems needs to consider anticipated electrical faults and those that challenge the continuity of supplies on the power station e.g. Station Blackout. This presentation will cover the design provisions that lead to defence in depth and robustness in electrical power systems and consider failure mechanisms that might undermine their reliability e.g. common cause failure. The presentation will draw out the type of information that a regulator needs to identify for effective regulatory assessment and inspection.

 

C.2 Derivation of limits, controls and conditions and establishment of regulatory conditions of authorisation - Phil Metcalf

Key words nuclear safety, instrumentation and control systems, electrical power systems nuclear power plants, research reactors, regulatory control, limits and conditions, conditions of licence

Synopsis

Based on the classification of structures systems and components and their importance to safety it is necessary to ensure that all safety principles and requirements are fulfilled in respect of design, manufacture, installation, commissioning and operation. This presentation discusses the important elements in this regard and the establishment of operational limits controls and conditions – again based on the importance to safety of the individual structures systems and components. It also addresses the regulatory authorization process and the associated conditions of authorization. The degree of regulatory effort to be expended in this phase based on safety classification considerations will also be discussed.

 

C.3 Design, conduct, reporting and follow up of inspection processes associated with electrical power systems and components - Peter Hughes

Key words nuclear safety, electrical power systems, nuclear power plants research reactors, regulatory inspection

Synopsis

This presentation will discuss the development and implementation of regulatory inspection and other compliance assurance activities primarily for the design and manufacturing phases. These are aimed to provide a good level of assurance that design processes are undertaken competently and that manufacturing processes will ensure that the items will be manufactured as designed and assessed to be fit for purpose and providing the necessary safety functions.

 

C.4 Example inspection programme for electrical power systems - Peter Hughes

Key words nuclear safety, electrical power systems, nuclear power plants research reactors, regulatory inspection

Synopsis

This presentation will build on the development of the inspection plan in C.3 to provide examples of regulatory inspection programmes.  The example are based on regulatory programmes for the inspection of electrical systems for new build and for operating power stations. The purpose of the example is to show how a regulatory body must plan its activities over the various lifecycle phases of the power programme to ensure that regulatory decisions are timely and effective.

 

Day 4 – Regulatory inspection processes for I & C systems

 

D.1 . Design and software  considerations for I & C systems - Peter Hughes

Key words nuclear safety, instrumentation and control systems, software, design guidelines, nuclear power plants, research reactors

Synopsis

NPP engineering is complex involving many technical disciplines and correct information is necessary at appropriate times in a project for each discipline to ensure that the designs are delivered as required. For systems important to safety, a structured development process with conservative design measures and sound engineering practice is needed and this applies to I & C systems and components important to safety. In addition, computer based systems are of increasing importance to safety in NPPs as their use has rapidly increased. They are used both in safety related applications, such as some functions of the process control and monitoring systems, as well as in safety critical applications, such as reactor protection or actuation of safety features. The dependability of computer based systems important to safety is of prime interest and must be ensured. This presentation discusses these issues import to design of I & C systems and the software used in such systems.

 

D.2 Application of FPGA based technology for I&C systems - Mauro Cappelli

Key words nuclear safety, instrumentation and control systems, field programmable gate arrays, nuclear power plants, research reactors

Synopsis

This presentation is mainly organized as a case study. Participants will work on minor tasks related to the assessment of I & C from a regulatory perspective and they will shortly present their findings. The objective of the exercise is to explain FPGA, a novel technology based on programmable devices. Advances over CPUB based systems as well as limitations of FPGA technology in the context of I & C applications will be covered and the genesis of FPGA technology. The (anti)economy of FPGA circuits will be addressed and where FPGA wins and where it loses:  comparison with standard programmable micro controllers and computer based control systems.  FPGA devices as glue logic and ASIC alternative will be covered as well as mixed signal (analogue) FPGA components. Design and simulation software tools for FPGA will be addressed together with the low level layer:  the CLB, the intermediate layer: VHDL and Verilog. The high level: functional block representation (e.g. LabVIEW) will also be addressed.

 

D.3 Design, conduct, reporting and follow up of inspection processes associated with I & C systems  and components

Peter Hughes

Key words Regulatory processes, nuclear safety, radiation safety, accidents, existing situations, abandoned facilities, orphaned sources

Synopsis

This presentation will discuss the actual development and implementation of regulatory inspection and other compliance assurance activities for all phases of reactor lifecycle form the design and manufacturing phases through commissioning and operation. These are aimed to provide a good level of assurance that design processes are undertaken competently and that manufacturing processes will ensure that the items will be manufactured as designed and assessed to be fit for purpose and providing the necessary safety functions.  It also deals with the initial contact with the operating management, arrangements for access to the various areas of the plant necessary, entrance meetings and conduct of the inspections. It deals with interactions during the inspection and the initial reporting of finding to the power station management. The documenting of findings is addressed and the categorization of finding in terms of significance and the need for corrective action and follow-up. The documentation of findings and the follow-up and close out of issues identified is covered. The presentation will be complemented by an example inspection programme.
