Final Report: Task 22 — Extreme Ground Motion Studies, John G. Anderson, James N. Brune, Jaak J.K. Daemen, Matthew Purvance

Publications (YM)

TASK 22 consisted of two separate investigations into extreme ground motions due to seismic events, Subtask 1 and Subtask 2. Subtask 1 included field studies of geological formations that should put an upper bound on extreme ground motions that have happened at the site of the formations. The locations are critically selected to provide the most effective constraints possible on the validity of the probabilistic seismic hazard analysis for Yucca Mountain. Subtask 2 surveyed recorded ground motions from around the world, with the aim to draw general conclusions from these as to the conditions where extreme ground motions are observed. …

Results Of Precipitation Monitoring At Yucca Mountain, N. Mcginnis, Amanda Brandt

Publications (YM)

This is the final report presenting precipitation data collected under task ORD-FYO4-007 “Precipitation Monitoring at Yucca Mountain”. This task acquired data using tipping bucket rain gauges to measure, with known accuracy, the accumulation and timing of precipitation in the vicinity of Yucca Mountain. Operation of the tipping bucket precipitation monitoring network was assumed by the Harry Reid Center for Environmental Studies (HRC) at the University of Nevada, Las Vegas (UNLV) in March of 2001. Precipitation monitoring data collection concluded June of 2008. All data presented in this report were collected during that time.

Environmental Effects On Corrosion Properties Of Alloy 22, Mano Misra

Publications (YM)

This document presents detailed technical report for four Subtasks that were conducted independently. All four Subtasks investigated environmental effects on corrosion properties of Alloy 22. The four Subtasks that were investigated are as follows: Subtask 1: Experimental Determination of Parameters for the General Corrosion Model. Subtask 2: Corrosion under Dust Deposits Containing Hygroscopic Salts. Subtask 3: Heated Electrode Approach for the Study of Corrosion Under Aggressive Conditions. Subtask 4: Effect of Hydrogen Permeation on the Stability of the Passive Film of Alloy 22.

Final Report: Nevada System Of Higher Education Quality Assurance Program, Nevada System Of Higher Education

Publications (YM)

The principal purpose of the cooperative agreement was to develop and continue providing the public and the Office of Repository Development (ORD) of the U.S. Department of Energy’s (DOE) Office of Civilian Radioactive Waste Management (OCRWM) with an independently derived, unbiased body of scientific and engineering data concerning the study of Yucca Mountain as a potential high-level radioactive waste repository. Under this agreement, the Nevada System of Higher Education (NSHE), formerly the University and Community CollegeSystem of Nevada (UCCSN), performed scientific and engineering research, and maintained and fostered collaborative working relationships between government and academic researchers. In performing these activities, …

Quality Assurance Services, Amy J. Smiecinski

Publications (YM)

The Nevada System of Higher Education (NSHE) Quality Assurance (QA) Program provides a full range of affordable QA services including records management, document and data control, training, and auditing. The program was regularly audited by the United States Department of Energy (DOE) to ensure strict compliance to regulatory requirements for nuclear facilities.

The NSHE QA Program is staffed by knowledgeable professionals who specialize in assisting smaller organizations who have no previous quality assurance experience.

Exceptional Ground Accelerations And Velocities Caused By Earthquakes, John G. Anderson, James N. Brune

Publications (YM)

This project aims to understand the characteristics of the free-field strong-motion records that have yielded the 100 largest peak accelerations and the 100 largest peak velocities recorded to date. The peak is defined as the maximum magnitude of the acceleration or velocity vector during the strong shaking. This compilation includes 35 records with peak acceleration greater than gravity, and 41 records with peak velocities greater than 100 cm/s. The results represent an estimated 150,000 instrument-years of strong-motion recordings. The mean horizontal acceleration or velocity, as used for the NGA ground motion models, is typically 0.76 times the magnitude of this …
