Climate change concerns, resource constraints on conventional energy sources, ever-increasing electricity demand with new loads on the consumer side, improving electricity access, and the new challenge of matching dynamic energy resources with dynamic demand have forced the transitions in electricity systems worldwide. The Indian electricity system is undergoing significant transitions concerning all segments, viz., electricity generation, transmission & distribution, and demand-side to manage such challenges. These transitions throw numerous challenges in technical, economic, social, and policy dimensions. This paper tries to elucidate these transitions and associated challenges in the Indian electricity system. The overall goal of the paper is to present such an understanding of these transitions to introduce appropriate interventions for the effective operation of future electricity systems. The electricity sector has a cardinal role in reducing global greenhouse gas emissions. Only a sustainable electricity system can cater to the needs of the people. It can be concluded that the electricity sector's transition is inevitable, and it is eternal.

This paper considers the physical processes in the structure of the material for a heat-emitting fuel element (FE) shell, caused by various damaging defects, on its outer and inner surfaces, and affecting the change in the geometric parameters of a nuclear reactor’s FE. The task to improve the model of damage to an FE shell is being solved, taking into consideration structural and phase changes in the material of the shell with damaging defects on the outer and inner surfaces, in order to establish the actual criterion for assessing the FE hermeticity degree. It is proposed to study the structure of the shell material with damaging defects (macropores and microcracks), which is a porous heterogeneous structure with fractal properties of self-similarity and scalability, to use the apparatus of fractal geometry. A physical model of the FE shell has been built and proposed, in the form of a geometric cylinder-shaped figure, which makes it possible to investigate the fractal properties of the structure of the material of the damaged shell and their influence on a change in the geometric parameters of FE An improved model of damage to the FE shell was derived, which makes it possible to take into consideration fractal increases in the geometric parameters of FE, for the established values of the fractal dimensionality. Experimental studies of the FE shell, using the skin effect, confirmed the theoretical results and showed the validity of the choice of practical use of the fractal dimensionality parameter as an effective criterion for assessing the hermeticity degree of an FE shell. It has been experimentally established that the value of the fractal dimensionality of 2.68 corresponds to the maximum degree of damage to the shell for a leaky FE.
