Nuclear energy is the second-highest producer of carbon-free electricity after hydropower. Currently, nuclear energy is generated from fission- where the nuclei of an atom split into several parts; however, research on the energy generation from fusion is ongoing. Nuclear reactors are termed as heart of this process. This paper reviews the major nuclear reactor involved in these reactors' power generation and working and provides a broader aspect of the GEN-IV reactor.

Many vital applications benefit from mobile multi-robot teams, including search and rescue, environmental monitoring, military, unmanned space exploration, hazard detection and analysis. Communication between robots is important for group coordination and information sharing in mobile multi-robot teams. Because many mobile robot applications involve scenarios where communication infrastructure is destroyed or unavailable, mobile robot teams must regularly connect with one another through ADHOC networking. In such situations, low over-head and energy efficient routing systems for sending information are essential. The most difficult task is to provide a unified foundation for robot communication. The framework of Mobile Robots is described in this paper, as well as a review and analysis of several research papers on Energy Efficient Routing in Robotic Wireless sensor networks (RWSN).

This paper explores the effects of injection/suction on MHD unsteady natural convective radiative flow of heat mass transfer in a plumb frequency. The governing partial differential equations are converted to non- dimensional forms and solved numerically by an efficient, implicit, iterative method of Crank Nicolson. Suction/injection is used to control the fluid flow in the channel, and an exothermic chemical reaction of Arrhenius kinetic is considered. A parametric study illustrating the influence of various physical parameters is performed. Numerical results for the velocity, temperature, ad concentration as well as the skin friction factor, surface heat and mass transfer rates have been presented for parametric variations of injection/suction, Grashof number, MHD, Prandtl number and Schmidt number. It is reported that the velocity profile increase as thermal grashof number increases. The temperature profile rises by the influence in increasing values of injection and decreases by increasing values of suction parameter. While concentration profile decreases by the increasing values of chemical reaction in the case of suction and injection. The dependence of the skin friction coefficient, rate of heat transfer and mass transfer on these parameters has been discussed.

This study examined the effects of a pressure gradient that was exponentially increasing or decreasing on the mixed convection flow of viscous reactive fluids in a vertical tube between two concentric tubes with r = 0 and r = b. The nonlinear partial differential equation governing the flow formation are solved using the implicit finite difference form where all time differentials were calculated using the forward difference formula, and second order central differences were utilized to approximate the first and second derivatives. The impacts of several physical parameters, including shear stress, the rate of heat transfer, mixed convection, viscous reactive fluid parameter, activation energy, Prandtl number, and exponential decaying/growing pressure gradient on skin friction and Nusselt number were investigated. It's intriguing to see that raising the values of Frank–Kamenetskii (λ), mixed convection (Gre) as well as exponential growing pressure term increases the velocity fluid, However, in the case of exponential decay, the parameter drop also causes the fluid's velocity to diminish. The results also showed that a small bump in the viscous reactive fluid parameter considerably improves the energy profile.
