Analysis of Three-Component Rotational and Translational Ground Motions from Source Physics Experiment Chemical Explosions and Local Earthquakes

Igel et al. (2005) demonstrated that using single point measurements of translational displacement and rotational strain can reconstruct the long-period teleseismic wavefield including wave-type, apparent velocity and propagation direction. We examine if this also holds true for higher frequencies at local distances. Four co-located three-component (3C) Eentec R-1 rotational velocity sensors and Kinemetric 3C accelerometers were deployed at the Nevada National Security Site (NNSS) to record 3 Source Physics Experiment (SPE) chemical explosions with yields of 90kg (SPE-1), 997kg (SPE-2), and 905kg (SPE-3) equivalent TNT. The four sensors were deployed 1-km from the source on granite, sedimentary, and alluvium outcrops. Three small earthquakes were also recorded, a Ml 3.3 at 28 km, a Ml 2.6 at 58 km, and Ml 3.5 at 123 km distance from SPE site. From the 3C rotational and translational motions, we measured the horizontal phase velocity of 450 m/s and 1125 m/s along two separate directions from the source consistent with near-surface geology. In contrast, the horizontal phase velocity measured for the Ml 3.3 earthquake is 5.4 km/s in the 0.1 to 10 Hz band with a propagation direction consistent with the epicenter location. While the earthquake exhibited very high coherency between 3C rotational and translational motions, the explosions exhibited more coherency with P-SV waves but less for SH-waves. This may be due to explosion SH waves originating from motions along joints or scattering near the source. This difference could be exploited as a discriminant between explosions and earthquakes.

Maintenance Plan for the Performance Assessments and Composite Analyses for the Area 3 and Area 5 Radioactive Waste Management Sites at the Nevada National Security Site (Rev.3)

U.S. Department of Energy (DOE) Order 435.1, Radioactive Waste Management, requires that performance assessments (PAs) and composite analyses (CAs) for low-level radioactive waste (LLW) disposal facilities be maintained by the responsible field office. This plan describes the activities performed to maintain the PA and the CA for the Area 3 and Area 5 Radioactive Waste Management Sites (RWMSs) at the Nevada National Security Site (NNSS). The plan is based on DOE Order 435.1 Radioactive Waste Management (DOE 2007), DOE Manual 435.1-1, Radioactive Waste Management Manual (DOE 2011), and DOE Standard DOE-STD-5002-2017, Disposal Authorization Statement and Tank Closure Documentation (DOE 2017). The facility’s Disposal Authorization Statement (DAS) specifies conditions for the continuing operation of a LLW facility. The DAS is issued based on a review of the facility's PA, CA, the maintenance plan, preliminary closure plan, and preliminary monitoring plan. The DAS specifies the limits and conditions on construction, design, operations, and closure of the low-level waste facility based on these reviews. The Maintenance Plan uses an Unreviewed Disposal Question (UDQ)/Unreviewed Composite Analysis Question (UCAQ) change control process to identify, evaluate, and control planned or discovered changes affecting the PA, CA, DAS, or other documents composing the Radioactive Waste Management Basis (RWMB). The UDQ/UCAQ process uses the PA and CA GoldSim models to calculate updated results, assess the significance of changes, and to assess the need to revise the PA, CA, or DAS. In addition to the change control process, the Maintenance Plan requires an annual review of all changes and an annual assessment of the need to revise RWMB documents, plans, and programs. The cumulative effect of all changes is assessed annually by preparing a revised PA and CA baseline model that is used to update PA and CA results. The updated results are used to assess compliance with the PA performance objectives and the CA dose constraint, and to assess the need to revise the PAs, CAs, and other documents, plans, and programs supporting the RWMB. An Annual Summary Report documenting the results and conclusions of the annual review is prepared and submitted to DOE.

Q-6 Fireset Requirements

This document provides requirements for all CDU designs to be used at the Q-6 firing sites [i.e., Technical Area 22, Building 34 (TA-22-00340; TA-40-0005; and TA-40-0015], including LANL-designed CDUs, firesets from other Department of Energy (DOE) sites, and commercial firesets. CDUs for other, non-Q-6 sites [e.g., Dual-Axis Radiographic Hydrodynamic Test (DARHT) Facility, Proton Radiography (pRad) Facility, Nevada National Security Site (NNSS), etc.] may have additional requirements that are not reflected here. While this document provides recommendations and examples for some aspects of fireset design, it is not intended to be a design guide. This document is intended for use by subject matter experts (SMEs) in fireset design. Those new to fireset design should consult SMEs before submitting a fireset for Q-6 approval.

UNREVIEWED COMPOSITE ANALYSIS QUESTION EVALUATION: Update of Composite Analysis Sources Potentially Interacting with the Area 5 Radioactive Waste Management Site, Nevada National Security Site, Nye County, Nevada

This unreviewed composite analysis question evaluation (UCAQE) assesses the impacts of the FFACO corrective actions on the Area 5 RWMS CA and the need to revise or update the CA Federal Facility Agreement and Consent Order (FFACO). The FFACO, a legal agreement among the NNSA/NFO, the state of Nevada, and the U.S. Department of Defense, establishes a process to identify, characterize, and implement corrective actions for historical sites on the Nevada National Security Site (NNSS) contaminated with hazardous or radioactive materials. Review of FFACO corrective actions involving sources of residual radioactive contamination potentially interacting with the Area 5 RWMS indicates that no significant changes affecting CA results and conclusions have occurred. Doses from the Area 5 RWMS, Industrial Sites, and Soils sites are a small fraction of the 0.3 mSv CA dose constraint, and significant interactions with releases from the Area 5 RWMS are unlikely. Doses from FFACO CASs, including UGTA sites, can be controlled by FFACO URs and institutional controls that have been implemented since the CA was prepared. As the interactions between the Area 5 RWMS and the FFACO CASs are negligible, the sites can be managed independently. The Area 5 RWMS CA reached the same conclusions about the interaction of the Area 5 RWMS with other sources of residual contamination. Therefore, there is no need to revise or update the Area 5 RWMS CA.
