    This paper aims to explode nuclear fusion reaction, the theory behind nuclear fusion reactors and countries with different types of fusion reactors along with their fusion theory involved. The energy generated from nuclear fusion reaction is much more huge as compared to nuclear fission reaction, so there have been many research going on this field to explode efficient way to extract this energy into electricity through fusion reactors. The advantages of nuclear fusion over fission is also been discussed and why do we need nuclear fusion energy. Nuclear fusion reactors are key to future energy. Avinash Kumar Mishra | Dr. Anitha G.

    This paper outlines the use of nuclear fusion as a global warming mitigation technology. Life cycle CO2 emission from a nuclear fusion plant is quite low; it is comparable to that of nuclear fission. Nuclear fusion has the potential to contribute future energy systems and environment. The technological feasibility of nuclear fusion should be demonstrated in order to begin clarifying the potential contribution of nuclear fusion as well as to educate those outside of the fusion community about its potential.

    A technique is described for making nuclear fusion at room temperature by compressing a powder mixture comprising a deuteride and catalytic material. The result is explosive beyond known chemical reaction for the materials. This record was migrated from the OpenDepot repository service in June, 2017 before shutting down.

    A process is described for producing regular nuclear fusion at room temperature by compressing a deuteride mixed with catalytic material. The reaction is explosive beyond any possible chemical reaction for these materials. An attempt at explaining the nuclear processes in terms of soft X-ray emission has been made by deriving models of a deuteron and -particle. Future development for commercial energy production is discussed. This record was migrated from the OpenDepot repository service in June, 2017 before shutting down.

    A method to evaluate the reaction rate in nuclear fusion is proposed. This method is obtained in the framework of the elastic model for subbarrier fusion. Conditions for the validity of the method are given. Some examples are discussed.

    Abstract Developing a robust safety case is a key step in the development of a fusion power reactor for electricity generation. Plans for fusion power reactors are already underway and before nuclear facilities are licensed, they must demonstrate they satisfy several safety objectives involving keeping workers and the public safe and limiting any environmental impact. In this paper the key safety issues relating to fusion power are explored, including the current approach to fusion safety and methods of accident identification. The paper draws on major studies on the safety of fusion power plant concepts and the current work being undertaken for the ITER project. As well as discussing the key safety issues and potential accident scenarios, the paper identifies gaps in current knowledge together with areas for future work, including the establishment of internationally recognised safety standards for fusion power stations.

    Gerald Rosen (Ref. 1) estimates the fusion rate for deuterium molecules trapped in a metallic lattice by applying WKB barrier penetration formula. This comment proves that Rosen’s formula is incorrect. (AIP)

    Background: So far the feasibility of nuclear reactions has been studied only through the evaluation of the reaction rate, which gives us information about the kinetics, while the thermodynamic analysis has been limited to evaluations of the change in enthalpy without any consideration of the change in entropy. Methods: This work examines the thermodynamics of nuclear fusion reactions through a simplified approach. The analysis introduces the thermodynamic study of fission and fusion reactions through their comparison with a chemical process. Results: The main result is that fission reactions are always spontaneous (ΔG < 0) since a lot of energy is released in the form of heat and the system moves spontaneously towards a more disordered state. In contrast, fusion reactions are spontaneous only when the enthalpic contribution of the change in Gibbs free energy overcomes the entropic contribution. This condition is verified when the temperature of the process is below a characteristic value T*, calculated as the ratio between the energy corresponding to the mass defect and the change of entropy of the fusion reaction. Conclusions: Due to the unavailability of data related to entropy changes in fusion reactions, only a qualitative thermodynamic analysis has been carried out. Through such analysis, the influence of the operating conditions over the spontaneity of fusion processes has been discussed. The final considerations emphasize the role of the thermodynamics analysis that should be implemented in the current studies that, so far, have been mainly based on the assessment of the reaction rate and exothermicity of fusion reactions.

    We have developed a protocol for efficient fusion of spheroplasts of the same mating type. Nuclear fusion in this whole-cell system is also efficient and closely parallels nuclear fusion in heterosexual mating of intact cells. In the spheroplast fusion system, nuclear fusion is dependent on both the KAR1 gene and prior exposure to alpha factor. The major products of nuclear fusion in the spheroplast fusion assay were true diploids that were homozygous at the mating-type locus. An additional 10% of the products were cells of ploidy greater than diploid. The dependence of nuclear fusion on alpha factor treatment could not be replaced by synchronization in G1 by mutations in CDC28 and CDC35 or by prior arrest in stationary phase. These data suggest that nuclear fusion is not a constitutive function of the nucleus, but rather is specifically induced by mating hormone.
