LT61LEP-40 Phase II, Final Report

LT-40 Phase II evaluates the shear strength of Wilethane 44 (W44) when bonded to plastic bonded explosives (PBXs) as a function of accelerated aging time. These tests involve two PBX formulations, PBX 9502 and PBX 9012 (which is identical to the LX-07 formulation but lacks the orange dye). The LT-40 Phase I and Phase II test series differ from each other in their use of different lots of the two PBX formulations. The earlier LT-40 Phase I reports captured the initial shear strength data aged to 6 months [1] and18 months [2] for LX-07 lot 692 -5 and PBX 9502 lot 891-008. The Phase I final report [2] incorrectly refers to LX -07 as PBX 9012. These materials have the same formulation but, again, LX-07 includes orange dye. This report gives the Phase II data which includes the test results of 3-month and 6-month specimens [3] along with the18-month aged specimens of PBX 9012 Development Lot 1 and PBX 9502 Development Lot 2. The summary of all the LT-40 Phase II results are given and compared with the Phase I work. In a separate study, LT61LEP-21 [4 ], using the same Iosipescu loading configuration, the dependence of W44 shear bond strength as a function of cure time was investigated on the Phase I lots.

Testing Fast Reactor Fuels in a Thermal Reactor: A Comparison Report

The testing of fast reactor fuels in the thermal-spectrum of the Advanced Test Reactor using cadmium-filtering has been underway since 2003. The objective of this experimental approach to create a temperature profile inside of test fuel rodlets that is nearly prototypic of corresponding fast reactor conditions. This requires, necessarily, that the power generation profile inside of test fuel rodlets also be nearly prototypic of corresponding fast reactor conditions. By doing so, this experimental approach should allow for the study of fast reactor fuel performance phenomena that are primarily dependent upon the conditions of temperature and/or temperature gradient inside the fuel to be possible using a thermal test reactor. Validation of this assertion has been undertaken by both supporting analyses and by comparing fuel performance phenomena observed in fuels irradiated in cadmium-filtered positions in ATR to similar or identical fuels irradiated under similar conditions in genuine fast reactors. This report documents a preliminary comparison of fuel performance data available from the testing of metallic, oxide, and nitride fuels in cadmium-filtered positions in the ATR to the performance of identical or similar fuels irradiated in genuine fast reactors. Although a variety of fuel performance metrics are presented, particular attention is paid to those phenomena that are primarily, or significantly, dependent on conditions of temperature and temperature gradient with the fuel. Although the comparisons presented in this report are at this time limited in scope and preliminary in nature, they do support the assertion that the objectives of the cadmium-filtered testing approach in ATR are both feasible and appear sound. The analyses and comparisons presented in this report show that ATR irradiations performed using cadmium shrouding are sufficiently prototypic that they can be used with confidence in the development and testing of fast reactor fuels.

Investigation of Archived Gamma Data to Report Minimum Detectable Activities for Gamma-Emitting Radionuclides in Groundwater Samples

Los Alamos National Laboratory (LANL) has performed gamma analyses on ground water samples from the Nevada National Security Site (NNSS) (previously known as the Nevada Test Site or NTS) for the last 50 years. During that time, LANL has reported all of the detected radionuclides in various reports, letters and publications. However, until recently, no minimum detectable activities (MDAs) for undetected radionuclides of interest have been reported. In fact, most gamma emitting radionuclides were not detected in groundwater samples above their respective MDAs, and the MDAs can be used to define upper -bound activities for these radionuclides in the groundwater samples.

2017 Annual Reuse Report for the Idaho National Laboratory Site's Advanced Test Reactor Complex Cold Waste Ponds

This report describes conditions and information, as required by the state of Idaho, Department of Environmental Quality Reuse Permit I-161-02, for the Advanced Test Reactor Complex Cold Waste Ponds located at Idaho National Laboratory from November 1, 2016–October 31, 2017. The effective date of Reuse Permit I-161-02 is November 20, 2014 with an expiration date of November 19, 2019. A permit modification, I-161-02: Modification 1, became effective March 7, 2017. The modification incorporated clarification to the delivery of analytical reports and chain of custody forms. This report contains the following information: • Facility and system description • Permit required effluent monitoring data and loading rates • Permit required groundwater monitoring data • Status of compliance activities • Issues • Discussion of the facility’s environmental impacts. During the 2017 permit year, 234.05 million gallons of wastewater were discharged to the Cold Waste Ponds which is below the maximum annual permit limit of 375 million gallons. Sulfate and total dissolved solids concentrations continue to remain highest in well USGS-065, which is the closest downgradient well to the Cold Waste Ponds. As shown by the groundwater sampling data, sulfate and total dissolved solids concentrations decrease rapidly as the distance downgradient from the Cold Waste Ponds increases. The concentrations of all permit-required parameters were below their respective groundwater quality standard levels (IDAPA 58.01.11) for all six groundwater monitoring wells. There was one noncompliance with the Reuse Permit during the 2017 permit year. Approximately 600 gallons of cooling water was discharged to ground surface outside of the designated application site. DEQ was notified of the noncompliance.

Feasibility Evaluation of Potential Stimulation Methods for Collab Experiment 3. Recommendation Report

In support of the Collab Project Milestone 1.4, INL is to submit a recommendation report describing feasible methods to investigate during Experiment 3 to DOE. This report fulfils this FY18Q1 SMART milestone. Twenty one potential methods were consideration for testing as part of Collab Experiment 3. The potential methods have been categorized as; Fracture Initiation, Stimulation Fluids, Stimulation Methods and Flow Control. The categories have been further divided into three general groups (e.g. high, medium, low) based on applicability to the scale of measurement at Collab (~10 meter) and it’s applicably to FORGE. The highest relevant methods (not necessary in order) are: 1) fracture initiation within the borehole, 2) use of slickwater fracturing fluids, 3) use of viscous fracturing fluids, 4) simultaneous stimulation of multiple wells, 5) use of energetic fluids to initiate larger fractures or connect a borehole to existing fractures, 6) injection of diverters to control short circuits and working fluid loss, 7) testing of borehole isolation techniques to control water flow pathways in the reservoir, and 8) use of multiple injection and production wells to characterize a fracture. Fractures created in Experiments 1 and 2 offer the opportunity to test engineering solutions to issues encountered in the stimulation process or during the fracture flow testing. An advantage of using these sites is that there would be a wealth of baseline characterization data for the site, and the borehole monitoring system and experimental infrastructure is already established and could possibly be reused. This suggested potential method list should be considered preliminary due to the timing of this report and the status of Collab Experiments 1 and 2 as well as the need for preliminary modeling to assess each of the proposed methods effectiveness.

Final technical report

This final report covers the final year of the project. Reports from previous years were included in the group report for that year. The objective of this part of the project was to compare results from two large-scale, nonlinear plasma simulation codes based on magnetohydrodynamics, M3D and M3D-C1, for plasma edge instabilities. This is a difficult undertaking and the comparison was only partially successful because, while the MHD equations are standard, there are a number of valid MHD models of the plasma dissipation that make different approximations to their physics and the numerical implementation of a given model can be quite different depending on the way that the rest of the equations are solved. Large differences arise, and have major effects on the predicted plasma behavior, in the case of the greatest interest to this project, the plasma edge region under conditions where the plasma edge instabilities are strongest and the background plasma changes abruptly from interior hot, dense conditions to an unconfined, cool, diffuse plasma outside the magnetic boundary surface. Experimental observations only partially measure the background plasma and there are many non-MHD processes that can have important effects (studied in the rest of the project). Comparisons for edge instabilities at very small amplitude, the so-called linear modes, had showed good agreement for a few interior plasma instabilities, but strong differences between the default models for the plasma edge.

Report on Developing a US-China Joint Project on CO2-Based Fracturing Techniques

There are several types of hydraulic fracturing methods that have been investigated in the past decades that use little or no water. The criteria for selecting an optimal hydraulic fracturing fluids are many, and no single fluid can meet all the desired characteristics. Developing a set of technologies by using different fracturing fluids can better meet individual geologic, economic, and environmental needs. CO2 as an alternative of water for hydraulic fracturing has its unique place among all other fracturing fluids, and can meet both economic and environmental objectives under certain circumstances. There are three main categories of CO2-based fracturing fluids, simple liquid CO2 (LCO2), directly thickened LCO2, and CO2-foams/emulsions. Although LCO2 has many advantages, critical disadvantages arise due to its high operating pressure, low viscosity, poor proppant-carrying capacity, and generation of shallower fracture networks. To date, techniques for direct thickening of LCO2 to overcome these limitations have proven ineffective. To increase the apparent viscosity of CO2, we propose to further develop CO2-foam (and emulsion) fracturing techniques. While CO2-foams have long been used in EOR, the required properties for hydraulic fracturing are different, and relatively few peer-reviewed publications and field test reports are available regarding their applications in fracturing, and the surfactants and additives used are often proprietary This report describes a brief state-of-the-art analysis of CO2-based hydraulic fracturing methods and then discusses a joint plan for a long-term R&D collaboration to advance the most promising CO2-based hydraulic fracturing techniques as part of the U.S.-China Clean Energy Research Center, Water Energy Technology (CERC-WET). The objective of this U.S.-China joint research project is to design and laboratory test a CO2-foam fracturing fluid system, and then conduct pilot field-tests on them in China’s Jilin Oilfield. This joint research project will benefit both U.S. and China for advancing their shared goal of developing better technologies for CO2-based fracturing. The Chinese CERC-WET has two teams joining the project, one from RIPED, responsible for aboveground infrastructure design and construction. Another team from the Jilin Oilfield will be responsible for the field test design and conducting the test. The U.S.CERC-WET team at LBNL will be responsible for providing the CO2-foam formulations and their rheology parameters to be tested in the field (a challenging task and a key to success); participating in the equipment design and field test design; assisting in analyzing field data; and reporting to U.S. DOE and CERC-WET.

Nevada National Security Site Environmental Report 2017-Attachment A: Site Description

This attachment expands on the general description of the Nevada National Security Site (NNSS) presented in the Introduction to the Nevada National Security Site Environmental Report 2017 . Included are subsections that This volume of the three-part report summarizes the site’s geological, hydrological, climatological, and ecological settings and the cultural resources of the Nevada National Security Site. The subsections are meant to aid the reader in understanding the complex physical and biological environment of the NNSS. An adequate knowledge of the site’s environment is necessary to assess the environmental impacts of new projects, design and implement environmental monitoring activities for current site operations, and assess the impacts of site operations on the public residing in the vicinity of the NNSS. The NNSS environment contributes to several key features of the site that afford protection to the inhabitants of adjacent areas from potential exposure to radioactivity or other contaminants resulting from NNSS operations. These key features include the general remote location of the NNSS, restricted access, extended wind transport times, the great depths to slow-moving groundwater, little or no surface water, and low population density. This attachment complements the annual summary of monitoring program activities and dose assessments presented in the main body of this report.
