Nuclear Engineering Computer Modules: Reactor Dynamics, RD-1 and RD-2.
Onega, Ronald J.
The objective of the Reactor Dynamics Module, RD-1, is to obtain the kinetics equation without feedback and solve the kinetics equations numerically for one to six delayed neutron groups for time varying reactivity insertions. The computer code FUMOKI (Fundamental Mode Kinetics) will calculate the power as a function of time for either uranium or plutonium. Either fuel can be used with one to six delayed neutron groups and one of three types of reactivity insertions: a constant reactivity, sinusoidal, or a ramp. The code does not compute any parameters so the neutron generation time must be provided. The user has the option of studying the effects of various time steps in solving the system. The objective of Module RD-2 is to examine the temperature feedback mechanism of a pressurized water reactor (PWR) and solve the one delayed neutron model with temperature feedback for a step insertion and a ramp insertion of reactivity. A PWR core with a two-path feedback is considered. The core region is the only one of interest in this module. The program name is FUMOTEM (Fundamental Mode Kinetics with Temperature Feedback). There are four types of reactivity inputs that the program can accommodate. (Author)
