Professor Andrew C. Kadak Professor of the Practice Lecture 3 Reactor Kinetics and Control. Prof. Andrew C. Kadak, • Reactor follows point kinetics equations • Prompt jump – drop – Problems: 1,4,6,9 • Read Chapter 6 for next class. MIT OpenCourseWareFile Size: KB. This paper describes a multi-nodal advanced nuclear reactor core model, developed and benchmarked by CAE Electronics Ltd in collaboration with Koclas Logic Systems Ltd. (KLSL). The model is based on application of modern equivalence theory to the solution of neutron diffusion equation in real time employing the finite differences : Jean Koclas, F. Friedman, C. Paquette, P. Vivier. When an atom in a nuclear reactor fissions, neutrons are released at high energy (fast speeds). In thermal reactors (nearly all current commercial ones) the fission neutrons are slowed down to low (thermal) energies by collisions with light atoms within the reactor – hydrogen in the water in water-cooled reactors, deuterium in heavy water (D2O) in heavy water cooled reactors, or carbon in. Benchmark calculations for a variety of thermal and fast reactors have been performed by using the newly evaluated JENDL-3 Version-2 (JENDL) file. In the thermal reactor calculations for the uranium and plutonium fueled cores of TRX and TCA, the k{sub eff} and lattice parameters were well predicted.

Heavy water (deuterium oxide, 2 H 2 O, D 2 O) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium (2 H or D, also known as heavy hydrogen), rather than the common hydrogen-1 isotope (1 H or H, also called protium) that makes up most of the hydrogen in normal water.

The presence of deuterium gives the water different nuclear properties, and the Chemical formula: D, ₂O. In this paper, the famous TWIGL reactor kinetics problem, the LRA super prompt-critical transient problem and the three dimensional transient LMW problem (Kotchoubey,Benchmark Problem Book,Christensen,Shober, ) are analyzed to test the numerical properties of STFT_GNEM.
