In this study, the behaviour of the triple product (niτE Ti) and height of the saddle point are investigated on the basis of the particle and power balance equations by considering primary reaction and side reactions among all product and reactant species in a spherical torus nuclear fusion reactor. For this purpose, a set of equation are coupled and solved numerically. Ignition capability is investigated and compared for different types of side reactions and other features like, the ratio between particle and energy confinement time and hot ion modes. Finally the results are compared with each other to improve future research.
