Method for determining the uncertainty of gap conductance deduced from measured fuel centerline temperatures. [BWR]

Description: The paper describes the method which was developed to determine the uncertainties of gap conductances deduced from measured fuel centerline temperatures of NRC-RSR/BPNL fuel rods irradiated in the Halden Boiling Water Reactor. The ..integral..k(t)dt method is used to calculate the fuel surface temperature from the measured fuel centerline temperature and the fuel thermal conductivity. The gap conductance is calculated from the fuel surface temperature, the calculated cladding inside surface tem… more

Health and environmental effects document for direct coal liquefaction - 1981.

Description: This document presents initial estimates of potential human health effects from inhalation of nonmethane hydrocarbons (NMHC) that may be released from a future hypothetical industry producing about 600,000 bb1/day of synthetic fuel by direct liquefaction of coal. The assessment approach starts wth general assumptions that are then refined in a tiered sequence that considers available epidemiological, environmental and chemical data. The uncertainties involved in such an evaluation have been qua… more

Evaluation of CHESS: Utah asthma study, 1971-1972. Final report

Description: This report is divided into five main sections. The first reviews the use of asthma as a health indicator in environmental epidemiology, including a review of selected asthma panel studies. The next two sections consider the impact of the data quality: the limitations and characteristics of the aerometric data and of the panelists' data, respectively. The last two sections contain statistical analyses: analyses correcting for variation among panelists and analyses based on person-days.

Evaluation of fuel fabrication and the back end of the fuel cycle for light-water- and heavy-water-cooled nuclear power reactors

Description: The classification of water-cooled nuclear reactors offers a number of fuel cycles that present inherently low risk of weapons proliferation while making power available to the international community. Eight fuel cycles in light water reactor (LWR), heavy water reactor (HWR), and the spectral shift controlled reactor (SSCR) systems have been proposed to promote these objectives in the International Fuel Cycle Evaluation (INFCE) program. Each was examined in an effort to provide technical and ec… more

Fuel cycle cost studies: fabrication, reprocessing, and refabrication of LWR, SSCR, HWR, LMFBR, and HTGR fuels

Description: The comparative analysis of power generation costs for the various reactor cycles that is being performed in the Nonproliferation Alternative Systems Assessment Program (NASAP) and the International Nuclear Fuel Cycle Evaluation (INFCE) requires that the costs associated with processing of fuel materials for use in these cycles be estimated. The study described here provided unit cost estimates for the fabrication, reprocessing, and refabrication of a variety of fuels for several reactor system… more

Uncertainty in North America wet deposition isopleth maps: Effect of site selection and valid sample criteria

Description: This report considers several issues related to the preparation of isopleth maps for the display of spatial patterns of wet deposition. The valid sample criteria and data completeness rating used in the data summarization process are described. The data interpolation technique, kriging, is presented and it's derivation in terms of generalized least squares regression is given. Four different annual summaries for pH, sulfate concentration, and sulfate deposition in 1986 are prepared using e… more

Assessment of electrochemical potentiokinetic reactivation tests to qualify stainless steel for nitric acid service

Description: To minimize the costs and delivery time delays associated with purchasing type 304L stainless steel materials for service in nitric-acid-containing media, an alternative to the current Oak Ridge Y-12 Plant requirement of testing in accordance with American Society for Testing and Materials (ASTM) A 262, Practice C (the boiling nitric acid test), is being sought. A possible candidate is the electrochemical potentiokinetic reactivation (EPR) test being developed for the nuclear industry and under… more

HRP Radiation Corrosion Studies

Description: A fifth in-pile loop experiment, L-4-8, was completed. The loop operated in-pile for a total of 1637 hr, during which time the LITR energy output was 4377 Mwhr. The average fission power in the loop based o cesium analyses was 622 w when the LITR was at full power (3 Mw). Based on oxygen data, the generalized corrosion rate for the first 300 hr was 4.0 mpy; the rate for the remaining 1357 hr was 0.7 mpy. The nickel data gave parallel results. The corrosion of the type 347 stainless steel, Zirca… more
