Kinetics Of

The results of investigations of the kinetics of hydrogen generation compositions with aluminum, chemical activators (hydrated sodium metasilicate, oxide and calcium hydroxide) boric acid. Aluminium and its alloys used for the manufacture of protective sheaths of fuel elements and control rod protection system management, pipelines, tanks, and various support structures in the active zone of atomic reactors RBMK, research water-cooled reactors. The aluminum is protected from direct contact with water and steam surface layer of metal oxide having a high corrosion resistance at high temperatures in powerful radiation fields. However, after removal or when the discontinuity of the oxide layer of activated metal efficiently decompose water to hydrogen. It is established that the hydrogen aluminum-containing compositions is dependent on the concentration of boric acid. The discovery of the involvement of boric acid in these reactions expands the ideas about regularities of chemical processes of formation of hydrogen flowing in the water coolant of VVER reactors with the participation of the corrective additives and impurities.

The Integrated Modular Avionics System (IMA) has been a core technology for the new generation of aircrafts in recent years. It consists of a set of reusable and interoperable common functional modules. However, the highly coupled relationship of resources makes it difficult to identify and control dangers. As an effective and efficient way, the blueprints are used to describe and manage the IMA system. Owing to the system management functions provided by the blueprints, we can accurately determine the system resources configuration status, which is very crucial for safety analysis. In this paper, we explore the possibilities to conduct safety analysis based on blueprints. A safety analysis method based on blueprints is proposed, which applies mathematical logic to describe the logical relationship between targets and resources provided by the blueprints and uses semi-tensor product of matrix theory to simplify the logical expressions. Based on the mathematical model, we can conduct the fail safety analysis and identify resources failures that may undermine the IMA system safety.
