This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A Cryogenic Irradiation Facility (CRIF) has been designed, fabricated, and tested for use in the pool of the Ohio State University Research Reactor (OSURR). This CRIF will support in situ radiation induced damage experiments in optical and electronic materials from cryogenic temperatures and temperature controlled low temperature annealing experiments from cryogenic temperatures to above room temperature. The facility has been tested with liquid nitrogen and liquid helium out of the reactor pool. Temperature control has been demonstrated in the experimental volume of the CRIF from 4.2 K to above room temperature. The 10" Dry Tube, which will house the CRIF in the OSURR pool, has been inserted into OSURR pool and tested. The empty 10" Dry Tube and the CRIF have been simulated in a model of the OSURR using MCNP6 to understand the predicted radiation fields and total energy deposition in the empty 10" Dry Tube and in typical optical and electronic materials in the experimental volume of the CRIF. The radiation fields and the total radiation energy deposition have been used to predict experimental operating parameters for future CRIF experiments, based upon desired dose calculations and time to boil-off for the liquid helium inside the CRIF.

This book was released on 2008 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The objective of this work is to provide more accurate neutronic models of the OSU research reactor and also to provide a more complete characterization of the energy-dependent neutron flux spectrum present at the various experimental facilities of the reactor. This work will allow for a better predictive capability, so that experimental results can be better anticipated. Two models are analyzed, one with a very detailed core geometry, the other with a more homogenized core. The two models were refined and made to be more accurate in various ways. Also, experimental benchmarking of these computer models is included, specifically using material activation experiments and spectral deconvolution (or unfolding) codes. In these programs, the wires' post-irradiation activities, their response functions, and an initial guess of the energy-dependent neutron flux spectrum are input into an iterative process, which outputs a energy-dependent neutron flux spectrum. The experimental and predicted energy-dependent neutron flux spectra are then compared to illustrate the differences between models.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study covers the computational efforts and theory performed to simulate a biological irradiation facility at Kansas State University's TRIGA Mark II Nuclear Reactor Facility, as well as model and optimize a path taken by a platform to uniformly irradiate a target sample. The work presented in here covers the steps taken to simulate the reactor as a radiation source, model a flask of water as a target, approximate the dose from a path taken through the beam, and optimize the path to reach uniform irradiation. Previous reactor models were improved with updates to MCNP thermal cross-section libraries and converted to a general radiation source. This source was used to simulate the energy deposited in a voxelized flask of water, following a path in front of a reactor beamport in discrete steps, based on a series of parameters which set the velocity over different sections. The simulation output was used to construct a matrix with rows for each step function velocity and columns for the impact on each voxel, which has a parameter vector that minimizes the deviation in dose. Finally, simulation of a random position machine was performed to investigate how this process may change with the added constraint of flask gravity. The algorithms applied were able to converge to a series of linear motions that brought 99.7% of voxel doses within 10% of the median dose for both random and nonrandom initial parameters. There is a relationship between the parameters defining the path and the expected gravity vector, which can be randomly sampled to obtain paths with the expected gravity. Incorporating dose uniformity with gravity constraints would require both linear and rotational motion. Doing so with current memory use would be outside of the application of the algorithms in this work.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this thesis is to provide instruction on the design, modeling, construction, and implementation of a cryogenic tracer irradiation facility that produces isotopically pure noble gas samples both efficiently and cost effectively. These samples will be used for various research purposes. This facility will be installed into Beam Port 1 (BP1) of The University of Texas at Austin's Nuclear Engineering Teaching Lab (NETL) TRIGA Mark II reactor core. This work builds on previous creation of noble gas activities of 127Xe and 37Ar on the order of 3.7x1010 Bq (1 Ci). These were produced through the activation of 126Xe and 36r, respectively, in the 3-Element facility which sat within the reactor core. This new facility offers means to produce these tracer gases in ways that are much safer and more cost-effective. Methods developed include solidification of the respective gases to increase sample density, change of location, and new facility components. The most important aspect of the design is the changes made to increase sample density by way of cryogenically freezing the gases onto a condenser. Beam Port 1 was chosen because it is larger than the in-core facilities and provided a safer location than in the core itself in the event that the pressure safety limit was exceeded. To efficiently freeze these gases a condensing system was designed and built by Cryomech Inc. The condensing system is composed of an irradiation canister, heat exchanger, helium compressor and transfer lines, and gas transfer lines

Available in PDF, EPUB and Kindle. Book excerpt: Faculty and students in the Nuclear Engineering Program at the Ohio State University (OSU) have proposed a conceptual design for an inherently safe 340 MWe power reactor. The design is based on the state-of-the-art technology of LWRs and the High Temperature Gas- cooled Reactors (HTGRs). The OSU Inherently Safe Reactor (OSU-ISR) concept uses shorter than standard BWR fuel elements in the reactor core. All the fluid on the primary side is contained within a Prestressed Concrete Reactor Vessel (PCRV). This important feature significantly reduces the probability of a LOCA. A new feature of the OSU-ISR is an operator independent steam driven Emergency Core Cooling System (ECCS) housed within the PCRV. In accident conditions where the steam generators are incapacitated, steam from the core drives a jet injector, which takes water from the suppression pool and pumps it into the core cavity to maintain core coverability. The preliminary analysis of the concept was performed as a design project in the Nuclear Engineering Program at the OSU during the Spring of 1985, and published in''Nuclear Technology.'' The use of a PCRV for ducting and containment and the replacement of forced recirculation with natural circulation on the primary side significantly improve the inherent safety of the plant. Currently, work is in progress for the refinement of the OSU-ISR concept, partially supported by a grant from the U.S. Department of Energy.

Available in PDF, EPUB and Kindle. Book excerpt: The Department of Nuclear Engineering and Radiation Health Physics (NE/RHP) at Oregon State University (OSU) has been developing an innovative modular reactor plant concept since being initiated with a Department of Energy (DoE) grant in 1999. This concept, the Multi-Application Small Light Water Reactor (MASLWR), is an integral pressurized water reactor (PWR) plant that utilizes natural circulation flow in the primary and employs advanced passive safety features. The OSU MASLWR test facility is an electrically heated integral effects facility, scaled from the MASLWR concept design, that has been previously used to assess the feasibility of the concept design safety approach. To assist in evaluating operational scenarios, a simulation tool that models the test facility and is based on both test facility experimental data and analytical methods has been developed. The tool models both the test facility electric core and a simulated nuclear core, allowing evaluation of a broad spectrum of operational scenarios to identify those scenarios that should be explored experimentally using the test facility or design-quality multi-physics tools. Using the simulation tool, the total cost of experimentation and analysis can be reduced by directing time and resources towards the operational scenarios of interest.
