Available in PDF, EPUB and Kindle. Book excerpt: The problem of measuring the gamma heating in a mixed DT neutron and gamma ray environment was explored. A new detector technique was developed to make this measurement. Gamma heating measurements were made in a low-Z assembly irradiated with 14-Mev neutrons and (n, n(prime)) gammas produced by a Texas Nuclear Model 9400 neutron generator. Heating measurements were made in the mid-line of the lattice using a proportional counter operating in the Continuously-varied Bias-voltage Acquisition mode. The neutron-induced signal was separated from the gamma-induced signal by exploiting the signal rise-time differences inherent to radiations of different linear energy transfer coefficient, which are observable in a proportional counter. The operating limits of this measurement technique were explored by varying the counter position in the low-Z lattice, hence changing the irradiation spectrum observed. The experiment was modelled numerically to help interpret the measured results. The transport of neutrons and gamma rays in the assembly was modelled using the one- dimensional radiation transport code ANISN/PC. The cross-section set used for these calculations was derived from the ENDF/B-V library using the code MC2-2 for the case of DT neutrons slowing down in a low-Z material. The calculated neutron and gamma spectra in the slab and the relevant mass-stopping powers were used to construct weighting factors which relate the energy deposition in the counter fill-gas to that in the counter wall and in the surrounding material. The gamma energy deposition at various positions in the lattice is estimated by applying these weighting factors to the measured gamma energy deposition in the counter at those locations.

Available in PDF, EPUB and Kindle. Book excerpt: Gamma heating measurements have been made in a low-Z lattice irradiated with 14-MeV neutrons and (n, n(prime)) gammas produced by a Texas Nuclear Model 9400 neutron generator. Heating measurements were made in the mid-line of the assembly using a proportional counter operating in the Continuously-varied Bias-voltage Acquisition mode. The neutron-induced signal was separated from the gamma-induced signal by exploiting the signal rise-time rate differences inherent to radiations of different Linear Energy Transfer, which are observable in a proportional counter. The operating limits of this signal separation technique were explored by observing the effect on the signal as the neutron spectrum is shifted from a D-T spectrum to a softer though still fast neutron spectrum as the counter is placed further into the irradiation lattice. The experiment was modelled using the one-dimensional radiation transport code ANISN/PC. The cross-section set used for these calculations was derived from the ENDF/B-V library using the code MC2-2 for the case of D-T neutrons slowing down in a low-Z lattice. The calculated neutron and gamma spectra in the slab and the relevant mass-stopping powers were used to construct weighting factors which relate the energy deposition in the counter fill-gas to that in the counter wall and in the surrounding material. The total energy deposition at various positions in the lattice is estimated by applying these weighting factors to the measured gamma energy deposition in the counter at those locations. The overall utility of this measurement technique for fusion blanket neutronics is discussed. 8 refs., 5 figs., 2 tabs.

Download or read book The Measurement of Gamma Heating in a Fusion Blanket Test Assembly written by and published by . This book was released on 1989 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Determining the distribution of gamma heating in fusion test assemblies will help guide the construction and operation of future experiments. Currently the dominant technique for spatial characterization of heating is the wide dispersal of thin film TLD's, which are limited to measurement of the total neutron + gamma dose. The present work measures heating using calibrated proportional counters, which allows for the rejection of fast pulse-rise events characteristic of ionizations produced by neutron induced atomic recoils. A coupled calculational and experimental program designed to demonstrate this capability has been initiated at ANL. An irradiation assembly composed of graphite-filled 5 x 5 x 61 cm Mg sleeves in cubic geometry was constructed. This assembly was then irradiated in turn with Co-60 gammas and 14.8-MeV neutrons produced by a D-T neutron generator in two sets of measurements with the proportional counter occupying various positions in the central channel of the assembly. Calculation of the expected dose in the assembly due to the sources at the positions of interest were made. These calculations first generated the neutral flux profile in the assembly with either ANISN or MCNP depending on the degree of detailed used in the modelling of the counter. The profile is then fed into a charged-particle generation model to obtain the charged-particle profiles, hence energy deposition in the assembly. A comparison was made between these calculations of the energy deposition and measured energy deposition in the assembly. It is hoped that by understanding this comparison a clear picture of gamma heating in a mixed gamma and neutron environment will be obtained.
