This section is concerned with calorimetry to determine the classification of the reacting system (as described in Chapter 4) so that appropriate relief sizing methods can be used. The measurement of data for relief sizing is described in A2.4 to A2.6 below, depending on the results of the classification of system type for relief sizing. 

All of these classifications are naturally interrelated for a given chemical/biological engineering problem, and the best approach is to choose one main classification and then use the other problem s classifications as subdivisions. The most fundamental classification of systems is usually based upon their thermodynamical characteristics. This classification is the most general it divides systems into open, closed, and isolated systems which are defined as follows ...

The above has been an attempt, obviously subjective, to identify a chronological pattern to the subject under review. In the following discussion, less emphasis will be placed on the sequence of events than on classification of systems and the problems of interpretation. 

II, Chapters 4, 5, and 6 give all the information regarding the theoretical aspects involved in designing a complete NMMS and ensuring its successful implementation and maintenance. A complete system to detect, describe, analyse and follow-up near misses is outlined (Chapter 4), with special emphasis on a model-based classification of system failure (Chapter 5) a number of key issues relating to organisational aspects like acceptance by employees, and safety cultures are discussed in Chapter 6,...

Another classification of systems which is very important for deciding the algorithm for model solution, is that of linear and non-linear systems. The equations of linear systems can usually be solved analytically, while the equations of non-linear systems are almost always solved numerically. In this respect, it is important to recognize the important fact that physical systems are almost always non-linear and linear systems are either an approximation that should be justified, or the equations are intentionally linearized in the neighbourhood of a certain state of the system and are strictly valid only in this neighbourhood. 

Chapter 1 introduces the reader to system theory and the classification of systems. It also covers the main principles for the development of mathematical models in general and for fixed bed catalytic reactors in particular. 

Several ways of classification of systems are possible. One classification refers to the way how energy forms can be exchanged and another more recent classification... 

Because the HTR-10 test reactor is designed on the inherent safety philosophy, safety classifications of systems and components departure from the way it is done for water cooled power reactors For example, primary pressure boundary is defined to the first isolation valve Steam generator tubes are classified as Class II component Diesel generators are not required to be as highly qualified as those used for large water cooled power reactors, since no systems or components with large power demand would require an immediate start of the diesel engines at a plant black-out accident... 

A general agreement exists that classification of systems, structures and components of a plant from the point of view of safety and from the point of view of resistance to external actions (earthquake, and so on) is necessary to make decisions on the following ...

Taxonomy is a systematic representation of a system s existence (McKelvey 1982). Accordingly, taxonomy is built based on principles of system theory. It is a mechanism for structuring the knowledge about a certain system domain. The process of taxonomy development consists of information collection, systematic analysis, and classification of system attributes.
