Department of Energy - Statement of U.S. Energy Secretary Steven Chu on Meetings With I... - 0 views

  •  
    oday I have had the opportunity to meet with Deputy Chairman of the Planning Commission Dr. Montek Singh Ahluwalia and other distinguished Indian leaders. We had productive discussions about the opportunities for partnerships between our two countries on clean energy technologies. Meeting the climate and clean energy challenge is a top priority for President Obama. In the past ten months, the United States has demonstrated its renewed commitment to these goals both by supporting domestic policies that advance clean energy, climate security, and economic recovery; and by vigorously vigorously re-engaging the international community through bi-lateral relationships, the Major Economies Forum on Energy and Climate, the G20, and the UN negotiations. The U.S. will continue to work hard toward combating climate change and reaching a strong international agreement that puts the world on a pathway to a clean energy future. Working together, we can meet the clean energy and climate challenge in a way that will drive sustainable, low-carbon economic growth in the 21st century.

The Associated Press: Vt. nuke plant says flaw led to radioactive leak - 0 views

  •  
    "Officials at Vermont's only nuclear power plant say a design flaw that kept engineers from inspecting underground pipes helped cause a leak of radioactive water into the ground. In a report released Tuesday, Entergy Vermont Yankee says a pipe tunnel was blocked with construction material left over from the plant's construction in 1972 and prevented water contaminated with tritium (TRIHT'-ee-um) from passing through the drain line and into a tank. A separate pipe installed in 1978 created a pathway that allowed the contaminated water to reach the soil on the plant's grounds."

    The pros and cons regarding Yucca mountain are endless. It was in the late 1980s when all eyes were turned toward the State of Nevada - think about it - a small state with two new senators. There was Texas and the state of Washington with powerful leadership, as compared to our own little state of Nevada. Included in this mixture was the powerful nuclear industry pushing all the way to Nevada and Yucca Mountain. There are advantages to Yucca Mountain in that it is in a remote area along side the Nevada test site, wherein there had been nuclear testing. Think about human exposure over the next 10,000 years. Fractured rock that will provide a path down to the water table. Think also about the mountain as it sits quietly at this moment in isolation, but we have had earthquakes and this area is located in the southwestern Nevada volcanic field. There are a maze of faults and fractures beneath this mountain which make it difficult to model flow pathways.

Medical Effects of Internal Contamination with Uranium - Croatian Medical Journal v.40,... - 0 views

  • Early studies (Gmelin 1824) at the University of Tübingen on the biological effects of uranium indicated that uranium salts given by mouth present a hazard as a feeble poison, but facilitating death after intravenous injection. This work with pure uranium oxide prepared from pitchblende in the form of uranyl citrate, sulfide, and chloride was performed on experimental dogs and rabbits by oral and intravenous administration of uranium salts. The oral administration of uranium in the form of sulfate (300 mg) or nitrate (900 mg) did not demonstrate any immediate symptoms, whereas 4 g of uranyl nitrate produced emesis in dogs. Chloride salt given by a gastric tube (2 g) produced death in a rabbit in 52 hours. Pathomorpho- logical examination showed diffuse gastric inflammatory changes with leukocyte extravasation. Intravenous administration of 600 mg of uranyl nitrate or 180 mg of chloride killed a dog within a minute, with autopsy findings of coagulated blood in the right ventricle and great vessels, as well as considerable pericardial effusion. Only 3 out of 18 metals reported in Gmelin's work produced similar findings: barium, palladium, and uranium (26).

    The purpose of this work is to present an outline of the metabolic pathways of uranium isotopes and compounds, medical consequences of uranium poisoning, and an evaluation of the therapeutic alternatives in uranium internal contamination

NRC: Performance Assessment for Waste Disposal and Decommissioning - 0 views

  •  
    In the context of disposal of radioactive waste, a performance assessment is a quantitative evaluation of potential releases of radioactivity from a disposal facility into the environment, and assessment of the resultant radiological doses. The term performance assessment can refer to the process, model, or collection of models used to estimate future doses to human receptors. Typically, a performance assessment is conducted to demonstrate whether a disposal facility has met its performance objectives. In general, a performance assessment considers the following factors: * Selected scenario (specific features and processes at the disposal facility and in the surrounding area, such as the location of the potential release, location and general characteristics of the receptors, and applicable transport pathways through which radionuclides might reach the environment and pose a threat to the selected receptor groups) * Performance of the cask or other engineered barrier system used to store low-level waste, limit the influx of water, and reduce the release of radionuclides * Release and migration of radionuclides through the engineered barrier system and geosphere (those deep-underground portions of the disposal facility where human contact is generally not assumed to occur) * Radiological dose(s) to the selected receptor group(s)

FR: NRC: Criteria for Development of Evacuation Time Estimate Studies, - 0 views

    Draft Report for Comment AGENCY: Nuclear Regulatory Commission. [[Page 23220]] ACTION: Announcement of issuance for public comment, availability. ----------------------------------------------------------------------- SUMMARY: The Nuclear Regulatory Commission (NRC) has issued for public comment a document entitled: NUREG/CR-XXXX, ``Criteria for Development of Evacuation Time Estimate Studies.'' The Evacuation Time Estimate (ETE) is a calculation of the time to evacuate the plume exposure pathway emergency planning zone (EPZ), an area with a radius of about 10 miles around a nuclear power plant (NPP). The ETE is primarily used to inform protective action decisions during NPP radiological emergencies and may be used to assist in the development of traffic management plans to support an evacuation. This document is an acceptable template for use by NPP licensees to meet NRC requirements for the development of ETE studies. It also provides guidance for the update and review of ETEs. The format and criteria provided in this document will support consistent application of ETE methodology and will facilitate consistent NRC review of ETE studies.

EEOICP Site Exposure Matrices Website--Home Page - 0 views

  •  
    "The Department of Labor (DOL) Site Exposure Matrices (SEM) Website is a repository of information gathered from a variety of sources regarding toxic substances present at Department of Energy (DOE) and Radiation Exposure Compensation Act (RECA) facilities covered under Part E of the Energy Employees Occupational Illness Compensation Program Act (EEOICPA). In putting together SEM, DOL held round table meetings with workers from DOE facilities all over the country and gathered their input on the hazards at these sites. DOL also obtained copies of thousands of documents from DOE regarding toxic substances at those facilities. In addition to toxic substance information, the SEM Website also contains information regarding scientifically established links between toxic substances and illnesses. Displayed links for diagnosed illnesses show how these correlate to toxic substance exposures. The relationship between toxic substances and diagnosed illnesses shown in SEM is derived from records of research by recognized medical authorities maintained by the National Library of Medicine (NLM). DOL continually updates these relationships as new disease associations are recognized by NLM. The causal links provided by NLM do not represent an exclusive list of the pathways necessary for an affirmative Part E causation determination. Every case is evaluated on its own evidentiary merits. (Please note, however that SEM does not address the relationship between radiation and cancer. For purposes of EEOICPA, the relationship between radiation and cancer is evaluated by the National Institute for Occupational Safety and Health (NIOSH))."
