The study of the temperature response to power transients in a nuclear reactor covers an important link in the closed feedback loop of reactor kinetics. It is a necessary step in the determination of the kinetic behavior and stability of a power reactor and in the interpretation of oscillator tests. Similarly, the temperature response to inlet coolant temperature transients is important in determining reactivity effects fed in through or fed back around the coolant loops. Flow transients also affect the kinetic behavior of a reactor. The analysis presented is valid for any solid fuel reactor in Which there is little extraneous material besides fuel and coolant. An exact treatment of this problem consists in the solution of the transient heat transfer and heat conduction equations so as to yield the temperature at any point in the reactor at any time. In some cases, however, some simplifying assumptions can be made. These consist mainly in assuming that in those cases all or part of the temperature distribution does not depart much from what it is in steady state. Five models are considered in sucession. They are schematically represented. (auth)
