Lawrence Livermore National Laboratory Experimental Test Site 300: Energetic Materials Development Enclave (EMDEC) Soil Sampling and Analysis Plan Addendum 1 (April 2023)

The purpose of this addendum is to amend and update the Energetic Materials Development Enclave [project] Soil Sampling and Analysis Plan (SAP) dated June 2022 (LLNL-AM-22- 21678). In July 2022, portions of the SAP were completed. Since then, the project scope and limits have been redefined to include potential additional buildings. The exact locations of the additional buildings have not been determined, but the Project Management Office (PMO) would like to investigate at this time additional areas adjacent to the investigation area subject to the June 2022 SAP. The information contained in this addendum supersedes the June 2022 SAP. However, this addendum only addresses elements of the June 2022 SAP that were modified. Elements of the June 2022 SAP that have not been modified are relevant and will remain in effect.

Reference Mission Version 3.0 Addendum to the Human Exploration of Mars: The Reference Mission of the NASA Mars Exploration Study Team

This Addendum to the Mars Reference Mission was developed as a companion document to NASA Special Publication 6107, “Human Exploration of Mars: The Reference Mission of the NASA Exploration Study Team.” The Addendum summarizes changes and updates to the Mars Reference Mission the Exploration Office developed since the final draft of SP 6107 was printed in early 1998. The Reference Mission is a tool used by the Exploration Team and the exploration community to compare and evaluate approaches to mission and system concepts that could be used for human exploration missions. It is intended to identify and clarify system “drivers,” or significant sources of cost, performance, risk, and schedule variation. It does not represent a final or recommended approach to human Mars missions. Several alternative scenarios, including human exploration missions to the Moon, asteroids, or other targets beyond Earth orbit as well as employing different technical approaches to solving mission and technology challenges, are currently under study by the Exploration Team. Comparing alternative approaches provides the basis for continual improvement to technology investment plans and general understanding of future human exploration missions. The Addendum represents a “snapshot” of work in progress in support of planning for future human exploration missions through May 1998. Annual publications of revisions to the Reference Mission are planned beginning in late 1998.

Addendum: Unified framework for open quantum dynamics with memory

This Addendum presents a detailed analysis of the discretization error in time-integration and time-derivative that appear in the Nakajima-Zwanzig equation. This was brought to our attention by Makri et al. [arXiv:2410.08239]. Our analysis in the Addendum shows that the relationship derived in our earlier work [Nat. Commun. 15, 8087 (2024)] is valid within the choice of discretization and is not contaminated by the discretization error.

Addendum to the 2015 Eastern Interconnect Baselining and Analysis Report

This report serves as an addendum to the report 2015 Eastern Interconnect Baselining and Analysis Report (Amidan, Follum, and Freeman, 2015). This addendum report investigates the following: the impact of shorter record lengths and of adding a daily regularization term to the date/time models for angle pair measurements, additional development of a method to monitor the trend in phase angle pairs, the effect of changing the length of time to determine a baseline, when calculating atypical events, and a comparison between quantitatively discovered atypical events and actual events.

Sierra/SolidMechanics 4.48 User's Guide: Addendum for Shock Capabilities.

This is an addendum to the Sierra/SolidMechanics 4.48 User's Guide that documents additional capabilities available only in alternate versions of the Sierra/SolidMechanics (Sierra/SM) code. These alternate versions are enhanced to provide capabilities that are regulated under the U.S. Department of State's International Traffic in Arms Regulations (ITAR) export-control rules. The ITAR regulated codes are only distributed to entities that comply with the ITAR export-control requirements. The ITAR enhancements to Sierra/SM in- clude material models with an energy-dependent pressure response (appropriate for very large deformations and strain rates) and capabilities for blast modeling. Since this is an addendum to the standard Sierra/SM user's guide, please refer to that document first for general descriptions of code capability and use.

Addendum to water resource assessment in the New Mexico Permian Basin

There are an estimated 48,745 wells producing oil or gas in New Mexico as of August 8, 2020 and with advances in drilling and oil recovery technology the use of hydraulic fracturing has become more commonplace. With a typical well requiring 1.5 to 16 million gallons of water, there is an increased demand for water in the Permian Basin and concern over the regions ability to meet this demand. This report is an addendum to the 2018 report Water Resource Assessment in the New Mexico Permian Basin (SAND2018-12018) to monitor baseline water level and chemistry data established in the original report. Results from this addendum can be used to further understand regional water supply and demands and aid in the BLMs mission of sustainably meeting the needs of water users while protecting human and environmental health.

Addendum to Underground Test Area (UGTA) Closure Report for Corrective Action Unit 98: Frenchman Flat Nevada National Security Site, Nevada

This addendum to the CR for CAU 98, Frenchman Flat, NNSS, Nevada (compiled in DOE/EMNV, 2019) defines the long-term monitoring approach after a five-year evaluation of water sampling results, water-level measurements, and trends in water-level measurements. The approach was developed by Navarro and discussed in the report Corrective Action Unit 98: Frenchman Flat Five-Year Evaluation Nevada National Security Site, Nevada (DOE/EMNV, 2022), which was approved by NDEP. Sections 4.0 and 5.0 of the CR were rewritten to reflect the approach discussed in the five-year evaluation. Appendix C contains well construction diagrams that have been updated since the original CR was published. Appendix D contains updated Use Restriction (UR) forms and maps. NDEP requested an addendum instead of a complete revision to the Frenchman Flat CR so the history of the CR would not be lost.
