This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Generalized Area and .cap alpha./.nu. Methods of interpretation of pulsed-neutron measurements for subcritical reactivity were found to minimize the error caused by source-induced harmonics and kinetic distortion. The use of multiple neutron detectors distributed over the core of the reactor in the pulsed source measurements is recommended for increased accuracy of interpretation. The measured data are reduced to a reported value of the subcritical reactivity by the use of numerical solutions to the reactor eigenvalue problems. In the Generalized Area Method, the numerical solution provides an estimate of the static adjoint function which is used to weight the prompt and delayed neutron flux integrals measured in the experiment. These weighted integrals are then used to form the subcritical reactivity. In the .cap alpha./.nu. Method, the static eigenequation solved by numerical methods is transformed to a time eigenequation to provide a bridge between the measured decay constant of the fundamental mode and the subcritical static reactivity. Also, the transformation provides a means of normalizing the reported static reactivity. The evaluations were performed by applying both methods to numerical data generated by one-dimensional, space--time diffusion theory for which k/sub eff/ was known precisely. The Generalized Area Method was found to deduce reasonably accurate reactivity values from simulations of data from pulsed-neutron experiments in both large and small reflected reactors. The errors from the true reactivity ranged from +3% to -7% in rho at k/sub eff/ = 0.9. However, the single-detector Sjoestrand analysis failed badly for all pulsing simulations except for that of the small reactor with the source at the center of the core. Errors from the true reactivity ranged from +90% to -260% in rho at k/sub eff/ = 0.9. The .cap alpha./.nu. Method was applicable only to the small-reactor simulation where the error was -1% in rho at k/sub eff/ = 0.9.

Download or read book Accelerator Driven System at Kyoto University Critical Assembly written by Cheol Ho Pyeon and published by Springer. This book was released on 2021-03-20 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is a unique compilation of experimental benchmark analyses of the accelerator-driven system (ADS) at the Kyoto University Critical Assembly (KUCA) on the most recent advances in the development of computational methods. It is devoted especially to nuclear engineers and scientists. Readers will find a detailed description of advanced measurement techniques and calculation methodologies for the ADS with 14 MeV neutrons and high-energy neutrons (with combined use of 100 MeV protons and Pb-Bi target) at KUCA. Additionally, experimental results of nuclear transmutation of minor actinides by ADS and at a critical state are included. Readers also have access to benchmarks of specific ADS experiments with raw data in the Appendix. The book is a valuable resource for the ADS experiments at KUCA which are globally recognized as both static and kinetic studies from the point of view of fundamental research.
