Available in PDF, EPUB and Kindle. Book excerpt: An ongoing project to characterize the neutron beams at the Neutron Radiography Reactor (NRAD) is described in this paper. The effort has consisted of computer modelling with three dimensional diffusion theory to obtain a trail spectrum, foil activation measurements, and the use of SAND-II unfolding code. It was expected and found that diffusion theory will underpredict the fast flux. However, it is claimed that precise characterization of the entire spectrum is not necessary for comparisons among neutron radiography facilities; rather, the use of simple fast neutron indicators should be adequate. A specific example used at NRAD is the U-235/U-238 fission reaction rate ratio. A ratio such as this could be used in the same manner as the classic gold cadmium ratio for interfacility comparisons with regard to fast neutrons. 5 refs.

This book was released on 2013-03-08 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: For this Workshop, the organizers have attempted to invite experts from all known centers which are engaged in neutron beam development for neutron capture therapy. The Workshop was designed around a series of nineteen invited papers which dealt with neutron source design and development and beam characterization and performance. Emphasis was placed on epithermal beams because they offer clinical advantages and are more challenging to implement than thermal beams. Fission reactor sources were the basis for the majority of the papers; however three papers dealt with accelerator neutron sources. An additional three invited papers provided a summary of clinical results of Ncr therapy in Japan between 1968 and 1989 and overviews of clinical considerations for neutron capture therapy and of the status of tumor targeting chemical agents for Ncr. Five contributed poster papers dealing with NCT beam design and performance were also presented. A rapporteurs' paper was prepared after the Workshop to attempt to summarize the major aspects, issues, and conclusions which resulted from this Workshop. Many people contributed to both the smooth functioning of the Workshop and to the preparation of these proceedings. Special thanks are reserved for Ms. Dorothy K.

Book excerpt: In 1987 a series of experiments were conducted at the NRAD reactor facility at Argonne National Laboratory - West (ANL-W) to investigate the possibility of increasing the thermal neutron content at the end of the reactor's east beam tube through the use of hydrogenous flux traps. It was desired to increase the thermal flux for a series of experiments to be performed in the east radiography cell, in which the enhanced flux was required in a relatively small volume. Hence, it was feasible to attempt to focus the cross section of the beam to a smaller area. Two flux traps were constructed from unborated polypropylene and tested to determine their effectiveness. Both traps were open to the entire cross-sectional area of the neutron beam (as it emerges from the wall and enters the beam room). The sides then converged such that at the end of the trap the beam would be 'focused' to a greater intensity. The differences in the two flux traps were primarily in length, and hence angle to the beam as the inlet and outlet cross-sectional areas were held constant. It should be noted that merely placing a slab of polypropylene in the beam will not yield significant multiplication as neutrons are primarily scattered away.

Book excerpt: Methods for inspecting by neutron radiography have been demonstrated and are being applied to a wide variety of inspection problems. It seems reasonable to anticipate that the future availability of neutron sources other than nuclear reactors will contribute to much wider application of this technique in industry.

Book excerpt: TIlls book is the result of an effort made by several members of the Euratom Neutron Radiography Working Group (NRWG) to produce a new, revised and enlarged edition of the Neutron Radiography Handbooldlj (NRH), written by members of the NRWG and published in 1981, just before the First World Conference on Neutron Radiography (WCNR) (1981). Members of the NRWG have contributed with many papers both to the first (1981)[2), as well as the second (1986)[3) and third (1989) [4) World Conference on Neutron Radiography (WCNR). They were also among the editors of the proceedings of those conferences (1982, 1987, 1990). The NRWG was constituted mainly for the purpose of promoting neutron radiography (NR) in the field of nuclear reactor fuel. Therefore the next topical publication of the NRWG were Reference Neutron Radiographs of Nuclear Reactor Fuel (1984)[5). The book on Collimators for y Thermal Neutron Radiograph 6/ written in 1987 by a member of the NRWG was another publication in the same series of books on NR. To the same series belongs the present book on Practical Neutron Radiography (PNR). It will be followed soon by another book written by the members of the NRWG: Neutron Radiography on Nitrocellulose Filmf71. The NRWG concentrated its interest in the past years on the problem of dimensional measurements from neutron radiographs. The results of the investigation of this problem were summarized in a special EUR report about the Neutron Radiography Working Group Test Program[8/ published in 1989.

Nigg and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Idaho National Engineering and Environmental Laboratory (INEEL) and Washington State University (WSU) have constructed a new epithermal-neutron beam for collaborative Boron Neutron Capture Therapy (BNCT) preclinical research at the WSU TRIGATM research reactor facility1. More recently, additional beamline components were developed to permit the optional thermalization of the beam for certain types of studies where it is advantageous to use a thermal neutron source rather than an epithermal source. This article summarizes the results of some initial neutronic performance measurements for the thermalized system, with a comparison to the expected performance from the design computations.
