This paper deals with formal and simulation based verification methods of a primary-to-secondary leaking (abbreviated as PRISE) safety procedure. The PRISE safety procedure controls the draining of the contaminated water in a faulty steam generator when a non-compensable leaking from the primary to the secondary circuit occurs. Because of the discrete nature of the verification, a Coloured Petri Net (CPN) representation is proposed for both the procedure and the plant model. We have proved by using a non-model-based strategy that the PRISE safety procedure is safe, there are no dead markings in the state-space, and all transitions are live; being either impartial or fair.Further analysis results have been obtained using a model-based verification approach. We created a simple, low dimensional, nonlinear dynamic model of the primary circuit in a VVER-type pressurized water nuclear power plant for the purpose of the model-based verification. This is in contrast to the widely used safety analysis that requires an accurate detailed model. Our model also describes the relevant safety procedures, as well as all of the major leaking type faults. We propose a novel method to transform this model to a CPN form by discretization. The composed plant and PRISE safety procedure system has also been analysed by simulation using CPN analysis tools. We found by the model-based analysis -using both single and multiple faults-that the PRISE safety procedure initiates the draining when the PRISE event occurs, and no false alarm will be initiated.

“…The ever-increasing complexity, in conjunction with the market pressure for improved quality, safety, ease of use, and performance, promote the former as an important future bottleneck. Many model-driven software development approaches, typically relying on formal methods, are advocated as cost-effective approaches that support rigorous specification, validation, and testing of software [1,2]. Some standards, like [3,4], even make these methodologies compulsory.…”

h i g h l i g h t s• We discuss the role of supervisor synthesis in automated software code generation.• The proposed approach is systematic and based on process theory.• We implemented a model-based systems and software engineering framework.• The framework has been applied to multiple industrial studies. a r t i c l e i n f o a b s t r a c t We give an overview of a model-driven systems engineering approach for high-tech systems that relies on supervisory controller synthesis. The proposed framework has a process-theoretic foundation and supports extensions with quantitative features. We briefly discuss several industrial case studies that highlight the advantages of the proposed approach.© 2013 Elsevier B.V. All rights reserved. Model-driven control software developmentEmbedding information and communication technology in consumer and industrial products was enabled by advances in software that carries most of these products' functionalities. The need for development techniques that can guarantee software quality is more than apparent. Conferences like Software Development Automation, Model-Driven Engineering Languages and Systems, or Applications of Concurrency in System Design, are some of the venues where this need has been recognized and studied by means of automated model-driven software development techniques. In this paper, we would like to point to one model-driven systems engineering approach, referred to as supervisory controller synthesis, which targets discrete-event control software for high-tech and complex systems. We find this approach to be relevant to the software development community and we hope that it might offer novel insights in development of quality control software, and bring the communities of software development, systems engineering, and formal methods closer together.

A generic approach to build plant models for DES verification purposes

Abstract-The modeling of plant behavior is often essential in the design, performance analysis or diagnosis of Discrete Event Systems (DES). Yet this task remains a difficult one for which little research has been devoted. In this paper, we propose a technique for building behavioral models specific to large-scale plants, in order to perform a formal verification of the controller by means of "model-checking". In this aim, we have opted to use a modular approach with an appropriate class of automata. To obtain the overall plant model, parallel evolutions of the elementary automata are to be coordinated by a sequencer that ensures consistency of these evolutions.
