Title: Calculation of kinetic spatial weighting factors in power reactors

Abstract

Ex-core neutron detector kinetic (frequency-dependent) spatial sensitivities (weighting factors) for in-core neutron sources were determined by performing space-dependent, transport and diffusion theory, kinetic detector adjoint calculations in which both source propagation through fission processes and the frequency dependence of the reactivity-to-power transfer function were considered. This study was pursued to overcome the shortcomings of previous calculations of ex-core detector weighting factors for in-core neutron sources using discrete-ordinate shielding or point kernel techniques.

  • The ex-core detector response of the PWR core is calculated using the two-dimensional transport code. The following conclusions are obtained: The neutron scattering effect outside of the reactor vessel is rather big in the detector response calculation. When the authors calculate the assembly-wise weighting factors for the detector response using the two-dimensional transport code, the weighting factors of the peripheral assemblies not close to the detector but close to the reactor vessel become big. When the authors calculate the detector response during the one rod insertion test of the typical three-loop PWR core using the above weighting factors, the agreementmore » between calculation and measurement is very good. In the case of the simple point kernel calculational method widely used instead of the two-dimensional transport method, the authors obtain nearly the same result by correcting the method with the fractional angle seeing the detector from the reactor vessel outside surface.« less
  • From national topical meeting on mathematical models and computational techniques for analysis of nuclear systems; Ann Arbor, Michigan, USA (8 Apr 1973). In mathematical models and computational techniques for analysis of nuclear systems. The spatial xenon control problem is considered from an operational point of view. The objective is to eliminate on-going oscillations in minimal time, with minimal control actions, under design, operational, and fuel integrity constraints, and with due consideration of operator response time and human error potential. A formal approach to practical control procedures is formulated with the aid of the Pontryagin Minimum Principle directly in terms ofmore » axial offsets, and the physical concepts underlying the procedures are clarified. Examples are given of control simulations using a digital computer on time-share mode with a remote terminal, that links the reactor core, control system and instrumentation to a human operator in continuous operation in a linear transformation of real time. Suggestions are made for the use of on-line process control computers for the implementation of the control procedures. Recent experimental verifications of the control procedures in operating large PWR plants are discussed. 9 references. (auth)« less
