Yucca Mountain Project - 1999 Geographic Information System CD-ROM Project 스크랩

This Record is type of CD-ROM About the Project: The purpose of the Yucca Mountain Site Characterization Project is to determine if Yucca Mountain, Nevada, is a suitable site for a spent nuclear fuel and high-level radioactive waste repository. These materials are a result of nuclear power generation and national defense programs and will remain highly radioactive for thousands of years. Experts throughout the world agree that the most feasible and safe method for disposing of highly radioactive materials is to store them deep underground. Based on this consensus, the United States Congress passed the Nuclear Waste Policy Act of 1982 that directs the Department of Energy to find a site and characterize it. If the site is found suitable and a license application is approved by the Nuclear Regulatory Commission, the Department of Energy is to build and operate an underground disposal facility. The project involves extensive scientific study on Yucca Mountain's geology, hydrology, biology, and climate. If found suitable, Yucca Mountain could be part of the nation's first long-term solution to a compelling environmental problem.

Views on Proposed Legislation on Civil Penalties for Nuclear Safety Violations by Nonprofit Contractors 스크랩

* Four observations about the specific language in the bill 1. The definition of the amount of fee at risk is unclear. H.R. 723 while eliminating the exemption, provides a limitation on the amount of civil penalties that can be imposed on nonprofit contractors. 2. If the congress decides to limit the amount of fee at risk by specifying that "discretionary fee" means only the incentive fee portion of the total fee, the ability to impose penalties on nonprofit contractors may be limited 3. Under the proposed bill, limitations on payments for civil penalties would be extended to all tax-exempt nonprofit contractors, not just nonprofit educational institutions. 4. The penalty provisions specified in H.R. 723 would apply to contracts entered into after the date of enactment. Consequently, it could be many years before some of the contractors would have to pay a penalty. ◆ Continued Exemption of Nonprofit Contractors From Paying Civil Penalties is not Warranted - Los Alamos national laboratory, new Mexico. - Argonne national laboratory West, Idaho. ◆ Modifications to H.R. 723 could help clarify and strengthen the penalty provisions ◆ Limiting the amount of any payment for penalties made by tax-exempt contractors to the amount of the incentive fee could have unintended effects. - Contractors would be affected in an inconsistent way. - Enforcement of nuclear safety violations would differ from enforcement of security violations. - Disincentives could be created if the congress decides to limit the penalty payment to the amount of the incentive fee. ◆ Preferential treatment would be expanded to all tax-exempt contractors. ◆ Some contractors might not be subject to the penalty provisions until many years in the future.

Inadequate Justification for Relaxation of Computer Controls Demonstrates Need for Comprehensive Study 스크랩

Several implications of the changes to the control thresholds and the proposed change in U.S. computer export control policy related to increased risks for U.S. national security. ◆ The inadequacies of the President's justifications again demonstrate the need for a comprehensive study of the issues involved. ◆ The new rules effectively eliminate routine prior U.S. government review of computer exports below the licensing threshold to sensitive countries. In the past, we found that establishing a notification threshold lower than the licensing threshold was useful in that it allowed the U.S government to deny or defer some exports, or make other exports conditional upon additional safeguards. ◆ Raising licensing control thresholds in January 2001 increases the risk that more powerful computers might be exported without a license to sensitive customers nearly a year before Defense projects that these customers could attain the same computing power by clustering less powerful computers ◆ Defense and Commerce officials said that the U.S. government will have to rely more heavily on computer vendors to “know your customers“ and assess their intentions to use computers for proliferation purposes. Past evidence has shown this reliance may be misplaced. ◆ The policy proposal would reduce information that might be useful in detecting patterns of exports to customers engaged in proliferation activities because it would eliminate an annual reporting requirement that provides information on end users.
