The PHV-1000 steam generator is one of the main heat exchangers in the primary circuit of the power unit of nuclear power plants with a WWER-1000 reactor. The efficiency of its operation directly affects the thermal power and overall electricity generation of the power unit. The reliability of the heat exchange tubes forming the main heat exchange area is critical not only for thermal performance but also for the safety characteristics of the steam generator.

This article is devoted to the study of one of the priority issues that remains in scientific research, namely, the worldview and methodological understanding of the role and purpose of modern law and its principles through the prism of general legal theory.

The use of machine learning models for electricity consumption prediction for smart grid has been investigated. It was found that data pre-processing can improve the performance of the energy consumption prediction model, while machine learning algorithms can improve model prediction accuracy through the integration of multiple algorithms and hyperparameter optimization. It was found that the ensemble learning method can provide better prediction accuracy than each individual method by combining the strong features of different methods that have different structural characteristics.

The article defines the influence of European principles on the formation of social responsibility of local self-government.

The importance of effective interaction of public society institutions with state authorities is analyzed, because civil society institutions ensure the provision of high-quality and cost-effective social services, the organization of private individuals and legal entities under private law to independently satisfy their interests without additional financial or administrative costs from the state; spread of charity and provision of targeted and operational charitable assistance; participation in decision-making and thus ensuring greater effectiveness of decisions taking into account the in

The article carries out a philosophical and legal analysis of existing approaches to the definition of "transitional justice" and forms the author's position regarding its understanding. Two features of the emergence of the model of transitional justice are singled out: 1) the studied model is built on practical experience, and later became the basis of theoretical studies on transitional justice; 2) this model arises at the initiative of the international community as a reaction to repeated violations of human rights.

High-frequency (HF) and ultra-high-frequency (UHF) power measurements are applied in various industries both in the development and design of radio-electronic equipment and in testing, commissioning, or repair. Since such measurements are one of the basic types of measurement for metrological support in the field of radio engineering and communication, it is necessary to ensure metrological traceability of the calibration of working standards and measuring instruments to standards on fundamental constants in wide frequency and dynamic ranges.

In the article, the preparation and conduction of the Ukrainian exhibition by the Soviet leaders at the Marseille Fair is researched. The management experience in achieving objectives by the Ukrainian Soviet authorities is studied. Specific proposals on the effectiveness of public cooperation between Ukraine and the French Republic are given.

The article analyzes the main factors influencing populism on public administration in the historical aspect. It has been proved, as experience shows, that populism has always occupied a special place in the implementation of programs of political leaders and parties and their interrelation with public administration. Populism remains an actual phenomenon of socio-political life in many countries of the world.

Problem setting. The current development of Ukraine as a state, which constantly announces its path as irreversibly democratic, makes for more effective cooperation between state authorities and civil society institutions in all spheres of social and political life.
